1. Sector profile
Mining involves the extraction of minerals and other geological materials from the Earth, typically from an ore body, lode, vein, seam, reef, or placer deposit. These deposits form a mineralized package that is of economic interest to the miner. Mining operations typically include exploration, development, production, closure, and reclamation.
Sector activities and business relationships
Through their activities and business relationships, organizations can have an effect on the economy, environment, and people, and in turn make negative or positive contributions to sustainable development. When determining its material topics, the organization should consider the impacts of both its activities and its business relationships.
Activities
The impacts of an organization vary according to the types of activities it undertakes. The following list outlines some of the key activities of the mining sector, as defined in this Standard. This list is not exhaustive.
Exploration: Surveying of resources, including aerial surveys, seismic testing, and exploratory drilling.
Development: Design, planning, and construction of mining operations, including processing and worker facilities.
Production: Extraction of minerals and ores from the Earth, and separation of valuable minerals from waste material.
Closure and rehabilitation: Closure, decommissioning, dismantling, removal, disposal, or modification of assets, facilities, and sites.
Refining: Processing of raw materials into a refined product for further use in manufacturing.
Business relationships
An organization’s business relationships include relationships that it has with business partners, with entities in its value chain including those beyond the first tier, and with any other entities directly linked to its operations, products, or services. The following types of business relationships are prevalent in the mining sector and are relevant when identifying the impacts of organizations in the sector.
Joint ventures: represent a significant share of spending by mine site and are commonly used to perform mining operations or to provide products or services, including security. Some of the most significant impacts covered in this Standard concern the supply chain.
State-owned enterprises (SOEs): Are often the largest mining enterprises and hold ownership of the majority of global reserves. They may also serve as joint venture partners to publicly traded mining organizations. SOEs have specific challenges relating to transparency and governance, which are addressed in some of the likely material topics in this Standard.
Suppliers and contractors: Are used in large numbers in the mining sector to perform certain activities, such as drilling and construction, or to provide other services and products. Some of the significant impacts covered in this Standard concern the supply chain.
Customers: and other parties in the value chain are increasingly voicing expectations for supply chain traceability to ensure the responsible production of minerals. They, therefore, constitute a key driver of transparency in the sector.
The sector and sustainable development
The mining sector plays an important role in many national economies and can make significant contributions to the economic development of regions and countries. Low- and middle-income countries are most likely to rely on their natural resources as a primary driver of economic activity – a dependence that has grown steadily over the last few decades. In mining-dependent economies, responsible mining practices can lead to reductions in levels of poverty and overall improvements in social well-being.
Financial flows around mining projects are substantial, deriving, for example, from taxes, royalties, and other payments to governments or spending on suppliers. Along with providing employment opportunities, particularly in the supply chain, the sector also invests in infrastructure and community development projects. Benefits like these can contribute to long-term development needs and priorities for rural areas and countries that have limited sources of additional revenue. These flows represent important benefit streams but can also give rise to corruption.
Locating, extracting, and processing minerals entails complex scientific, environmental, and socioeconomic planning. The scale of mining projects can be significant, sometimes spanning vast areas and taking place over many decades. Government legislation, including environmental protections and tax regimes, set out by the countries where mining occurs largely regulate mining projects. If poorly managed, mining can create negative impacts with lasting implications for ecosystems, human rights, and the health, safety, and well-being of workers and local communities. Climate change brings additional challenges to managing the impacts of mining with consequences for water management, biodiversity, and extreme heat. Moreover, the decline of ore grades increases the amount of energy and resources needed by mining organizations to locate and extract minerals from rock, resulting in more pollution and waste generated [20].
Global demand for minerals is expected to increase due to continued economic growth, improved living standards, and the need to transition to a low-carbon economy. While minerals are essential to clean energy technologies that underpin global climate change mitigation goals, the sector is increasingly under scrutiny due to its contribution to GHG emissions and the need to reduce them in the value chain. The mining sector is also facing expectations to transition to renewable energy sources and implement circular economy principles, such as reusing and recycling existing materials.
The drive to mine certain minerals needed for clean technologies has also raised concerns over risks of increased environmental and human rights impacts. When higher-grade ores and proven deposits are depleted, mining activities may be driven to more remote or ecologically sensitive areas, areas characterized by water stress or inhabited by Indigenous Peoples, or fragile, conflict-prone states. Additionally, land use, displacement, environmental impacts, and the economic potential associated with mineral extraction can inflame conflict. This can sometimes result in violence against or within local communities.
Box 1. Gender in mining
Because of the significance of impacts that mining organizations have at a community level, there is a growing expectation to disclose information on their local impacts on the economy, environment, and people. As mining can have different impacts on women and men, organizations are also increasingly expected to consider and address the distinct impacts of their activities on different genders. For example, women are disproportionately and uniquely affected by environmental degradation, climate change, and mining-induced social impacts like sexual and genderbased violence [12] [21]. Additionally, a lack of job opportunities can affect women's financial independence, and conditions of work in the sector can pose additional health and safety risks for women [23].
Applying gender-specific human rights due diligence approaches can address these issues, including when conducting community engagement or assessing aspects related to land rights, security, grievance resolution, and social investments. Organizations can also implement gender-responsive corporate policies and codes of conduct in the workplace. Recognizing how the impacts of mining can be more adverse or beneficial depending on unique social circumstances can broadly contribute to meaningful engagement with affected stakeholders and result in more informed actions by organizations to manage their impacts [9] [18] [21] [26].
A number of topics in this Standard list reporting disclosures that include a breakdown of reported information by gender. This is especially important if the impacts or reported numbers differ significantly for women and men. Beyond these instances, organizations can proactively provide gender-disaggregated data for any other topic where relevant and useful.
Sustainable Development Goals
The Sustainable Development Goals (SDGs), part of the 2030 Agenda for Sustainable Development adopted by the 193 United Nations (UN) member states, comprise the world’s comprehensive plan of action for achieving sustainable development [11].
Since the SDGs and targets associated with them are integrated and indivisible, mining organizations have the potential to contribute to all SDGs by enhancing their positive impacts or by preventing and mitigating their negative impacts on the economy, environment, and people.
The mining sector can contribute to achieving Goal 7: Affordable and Clean Energy and Goal 13: Climate Action by supplying critical minerals necessary for the low-carbon transition while mitigating GHG emissions through the use of renewable energy and energy efficiency measures.
The sector has connections to Goal 6: Clean Water and Sanitation and Goal 15: Life on Land due to the impacts that water use and land use by mining organizations can have on local communities and the environment.
The mining sector can make meaningful contributions to Goal 8: Decent Work and Economic Growth and Goal 1: No Poverty because it provides an essential source of revenue and employment in many regions while also providing materials for other industries that drive economic growth. With proper management of environmental impacts and the continuing supply of materials that enable infrastructure development, the mining sector can contribute to Goal 11: Sustainable Cities and Communities and Goal 12: Responsible Consumption and Production.
Table 2 presents connections between the likely material topics for the mining sector and the SDGs. These links were identified based on an assessment of the impacts described in each likely material topic, the targets associated with each SDG, and existing mappings undertaken for the sector (see reference [32] in the Bibliography). Table 2 is not a reporting tool but presents connections between the mining sector’s significant impacts and the goals of the 2030 Agenda for Sustainable Development. See references [32] and [31] in the Bibliography for information on reporting progress towards the SDGs using the GRI Standards.
2. Likely material topics
This section comprises the likely material topics for the mining sector. Each topic describes the sector’s most significant impacts related to the topic and lists disclosures that have been identified as relevant for reporting on the topic by mining organizations. The organization is required to review each topic in this section and determine whether it is a material topic for the organization, and then to determine what information to report for its material topics.
Mine-site disclosure
This disclosure applies to organizations that own or operate mine sites.5
Mining activities have impacts that often manifest locally. Given that an organization’s operations may span diverse regions, environments, and jurisdictions, impacts can vary greatly depending on where activities occur. An organization should assess and report information about its impacts in relation to appropriate local contexts (see the Sustainability Context principle in GRI 1: Foundation 2021 for more information).
Several topics in this Standard include mine-site-level reporting. Where impacts are highly significant for some mine sites and not others, organizations should provide site-level information about the sites where impacts are highly significant.
In other cases, disaggregated data may be needed for all mine sites to allow information users to make accurate assessments about the organization's overall contributions to sustainable development. These include certain public interest topics, such as greenhouse gas (GHG) emissions or biodiversity, where the mining sector has considerable impacts globally.
Organizations can proactively provide mine-site disaggregated data for any topic identified as material for reporting. Table 3 offers an example of how to present information for Disclosure 14.0.1. Organizations can use the table to indicate instances where impacts are highly significant for specific mine sites, and whether disaggregated data is provided for the site.
Topic 14.1 GHG emissions
Greenhouse gas (GHG) emissions comprise air emissions that contribute to climate change, such as carbon dioxide (CO2) and methane (CH4). This topic covers direct (Scope 1) and energy indirect (Scope 2) GHG emissions related to an organization’s activities, as well as other indirect (Scope 3) GHG emissions that occur upstream and downstream of the organization’s activities.
GHG emissions are the single biggest contributor to climate change. The mining sector’s activities and the use of mining products are responsible for a large portion of GHG emissions. Recent measurements indicate that available figures on GHG emissions from the sector could be underestimates.
GHG emissions from mining activities are classified as direct (Scope 1) GHG emissions in the case of activities owned or controlled by the organization or energy indirect (Scope 2) GHG emissions in the case of purchased or acquired electricity, heating, cooling, and steam consumed by the organization.
Direct (Scope 1) GHG emissions comprise emissions from fuel combustion during production, process emissions, and fugitive emissions. A substantial source of the sector’s Scope 1 GHG emissions is from the use of heavy machinery and equipment in mining operations.
Energy indirect (Scope 2) GHG emissions originate from stationary and mobile sources. The depletion of traditional mineral resources has led the sector to move production to more difficult settings, which may involve more complex extraction methods. These conditions are likely to increase the amount of energy used during production and transportation and, as such, GHG emissions associated with these activities.
GHG emissions resulting from the end use of products are classified as other indirect (Scope 3) GHG emissions. For the mining sector, these constitute a significant portion of GHG emissions. The majority of Scope 3 GHG emissions originate from downstream activities related to the use of mining products.

Topic 14.2 Climate adaptation and resilience
Organizations contribute to climate change and are simultaneously affected by it. Climate adaptation and resilience refer to how an organization adjusts to current and anticipated climate change-related risks, as well as how it contributes to the ability of societies and economies to withstand impacts from climate change.
Across the value chain, mining activities contribute to climate change by releasing GHG emissions (see also topic 14.1 GHG emissions). Changing climatic conditions, rising sea levels, and increasing intensity and frequency of extreme weather events already affect every region of the globe, causing negative impacts on the health, livelihoods, and human rights of millions of people. Physical impacts also pose risks to the workers, suppliers, local communities, and infrastructure, including transportation routes linked or adjacent to mining activities.
Climate change has been found to aggravate the impacts of mining on the local environment, disrupting biodiversity (see also topic 14.4 Biodiversity), affecting water quality and quantity, and exacerbating water stress (see also topic 14.7 Water and effluents). Climate change also heightens the risks of tailings storage facility failures due to increased rainfall (see also topic 14.6 Tailings and 14.15 Critical incident management). Rising temperatures can have negative impacts on air quality through the retention of particulate matter, which can exacerbate the impacts of air pollution (see also topic 14.3 Air emissions). In addition, climate change has the propensity to create drier climates where mining takes place, increasing the likelihood of dust events while diminishing the availability of water to suppress dust.
These impacts can have implications for the health, safety, well-being, and livelihoods of local communities and workers. They can also increase competition for natural resources, which often disproportionately affects women (see also topic 14.10 Local communities). Mining organizations can help strengthen local communities’ resilience to climate change-related impacts. Adaptation strategies can involve planning for post-mining land use, ensuring the availability of natural resources for agriculture, promoting climate-resilient economic growth, and long-term emergency planning. Organizations can also assist communities in obtaining reliable access to energy and water by, for example, establishing shared renewable energy infrastructure, implementing energy-saving programs, and sharing water resources.
The transition to a low-carbon economy is expected to increase demand for critical minerals needed for clean energy technologies, such as cobalt, copper, lithium, nickel, and rare earth elements. If managed well, this can present opportunities for mineral-rich countries through positive economic development (see also topic 14.9 Economic impacts). However, increased negative environmental and human rights impacts are recognized as a major risk. Many minerals that face rising demand are extracted from regions vulnerable to political instability, institutional weakness, and human rights violations. Mining in these areas can trigger or exacerbate conflict, corruption, environmental damage, and labor abuses (see also topic 14.25 Conflict-affected and high-risk areas).
Box 3. Scenario analysis
Scenario analysis allows for the simultaneous consideration of alternative forms of future states affected by climate change and can be used to explore climate change-related risks. Organizations typically define scenarios according to the transition speed expressed in the average global temperature changes. A scenario compatible with the Paris Agreement will require a temperature rise well below 2°C, pursuing efforts to limit the temperature rise to 1.5°C. Other scenarios can be defined according to an organization’s national context. For more guidance, see TCFD, The Use of Scenario Analysis in Disclosure of Climate-Related Risks and Opportunities, 2017 [82].

Topic 14.3 Air emissions
Air emissions include pollutants that have negative impacts on air quality and ecosystems, including human and animal health. This topic covers impacts from emissions of sulfur oxides (SOx), nitrogen oxides (NOx), particulate matter (PM), volatile organic compounds (VOCs), carbon monoxide (CO), and heavy metals, such as mercury (Hg).
In addition to greenhouse gas (GHG) emissions, mining activities are a source of other anthropogenic air emissions classified as pollutants. Globally, air pollution causes acute health problems and millions of deaths annually by contributing to heart and lung diseases, strokes, respiratory infections, and neurological damage [90]. Air emissions are a major concern for the sector’s workers (see also topic 14.6 Occupational health and safety) and local communities adjacent to mine sites and transportation routes (see also topic 14.10 Local communities). These emissions disproportionately affect children, the elderly, and the poor [89]. Air emissions from mining activities also have negative impacts on nearby ecosystems (see also topic 14.4 Biodiversity).
Mining activities release air emissions during drilling, blasting, excavation, overburden removal, storage, mineral processing, and transportation. Fugitive emissions can result from earthmoving, crushing, transportation, and pollutants from tailings facilities (see also topic 14.6 Tailings). These emissions mostly comprise dust and other particulate matter (PM). Depending on the mineral being mined, air emissions can also include heavy metals, carbon monoxide (CO), sulfur dioxide (SO₂), nitrogen oxide (NOx), hydrogen sulfide (H₂S), and volatile organic compounds (VOCs). The severity of impacts from air emissions can depend on the proximity of local communities and workers, and the sensitivity of local ecosystems.
The extraction and smelting of zinc and other non-ferrous metals produce mercury gases, which lead to severe health impacts. Mercury (Hg) is frequently used in artisanal and small-scale gold mining activities, sometimes located adjacent to mining organization’s concessions (see also topic 14.13 Artisanal and small-scale mining). Many gold and silver operations and refineries use cyanide to extract the mineral from ore, which can under certain conditions volatilize into hydrogen cyanide (HCN) and cause respiratory hazards for workers.8
Nitrogen oxide emissions from transportation can have negative impacts on ecosystems. They can enter waterways and oceans, have negative impacts on marine life, and generate ground-level ozone (O₃) or smog. Sulfur oxides from burning fossil fuels and smelting mineral ores containing sulfur can lead to acid rain and contribute to ocean acidification. In addition to negative impacts on human health, acid rain, and smog can degrade water and soil quality, impairing the functions of natural environments and thereby affecting food chains.
Box 4. Dust and particulate matter
Mining activities release significant amounts of particulate matter (PM), a pollutant mixture of solid particles and liquid droplets in the air. Dust is the main type of PM from mining, generated during blasting, digging, and hauling, as well as through conveyors, vehicles, and ore crushing. Dust can also be generated from exposed surfaces such as dirt roads, pits, waste piles, or dry tailings. Exposure to dust is associated with increased risks of heart and lung conditions for workers and communities. Dust can also impede the photosynthetic functions of trees and other plants.
Open-pit mining has a large geographic footprint, making dust management challenging. Organizations utilize dust control measures to prevent or mitigate dust exposure for workers and communities, including ventilation systems, dust collectors, irrigation bars, dry fog, water cannons, and bunds of trees. Air quality surveys can be undertaken to assess the adequacy of these controls.

Topic 14.4 Biodiversity
Biodiversity is the variability among living organisms. It includes diversity within species, between species, and of ecosystems. Biodiversity not only has intrinsic value, but is also vital to human health, food security, economic prosperity, and mitigation of climate change and adaptation to its impacts. This topic covers impacts on biodiversity, including on genetic diversity, animal and plant species, and natural ecosystems.
Mining activities typically require large-scale developments that have impacts on biodiversity and ecosystem services. These impacts can limit the availability and accessibility of natural resources or degrade their quality. Impacts on biodiversity and ecosystem services may also affect the well-being and livelihoods of local communities and Indigenous Peoples (see also topic 14.10 Local communities and 14.11 Rights of Indigenous Peoples).
Direct drivers of biodiversity loss influence biodiversity and ecosystem processes, leading to impacts such as degradation of ecosystems, habitat fragmentation, and animal mortality. Mining activities may contribute to the direct drivers of biodiversity loss through land and sea use change, for example, in the form of land clearance for mining, access routes, and waste management facilities; exploitation of natural resources by withdrawing and consuming water; through the introduction of invasive alien species; and pollution. Sources of air, water, and soil pollution can include:
- air emissions, including dust and fumes (see also topic 14.3 Air emissions);
- effluent discharges such as riverine tailings disposal (see also topic 14.7 Water and effluents);
- waste storage, disposal, and tailings facility failures (see also topics 14.5 Waste and 14.6 Tailings); and
- light, noise, and vibration.
Different mining methods present distinct impacts on biodiversity. Open-pit mines generate more severe impacts than underground mines due to the progressive deepening and widening of the mine site, increasing the affected areas over time. Open-pit mining is a prominent cause of deforestation, with nearly a third of all forests estimated to be affected by mining projects worldwide [110]. Removing carbon sinks and topsoil can also exacerbate GHG emissions (see also topic 14.1 GHG emissions), contributing to erosion and desertification. Underground mining, in turn, can have negative impacts resulting from ground subsidence and groundwater contamination.
Mining activities can have impacts on biodiversity beyond the mine site. These impacts can be more significant when mining occurs in or near ecologically sensitive areas. For example, mining activities can spread into ecological corridors and disrupt the functioning of an ecologically sensitive area. Inactive mine pits, underground workings, and hazardous waste can also cause biodiversity impacts beyond closure (see also topic 14.8 Closure and rehabilitation).
The increasing demand for minerals drives mining activities to ecologically sensitive areas, including previously undeveloped locations and marine ecosystems (see also topic 14.2 Climate adaptation and resilience). While the potential impacts of deep-sea mining are not fully understood, it is likely to disrupt marine ecosystems, compact or alter seafloor areas, create sediment plumes, and pose a risk of leaks, accidents, and spills on fragile habitats [105].
To limit and manage impacts on biodiversity, many mining organizations use the mitigation hierarchy tool to help inform their actions to balance or outweigh negative impacts on biodiversity [103]. The mitigation hierarchy follows avoidance, minimization, restoration, rehabilitation, and offset. Actions to avoid negative impacts are prioritized, as is minimizing those impacts when avoidance is not possible. Restoration and rehabilitation measures should be implemented when negative impacts cannot be avoided or minimized. Offsetting measures may be applied to residual negative impacts after all other measures have been applied.

Topic 14.5 Waste
Waste refers to anything that a holder discards, intends to discard, or is required to discard. When inadequately managed, waste can have negative impacts on the environment and human health, which can extend beyond the locations where waste is generated and discarded. This topic covers impacts from waste and the management of waste.
Mining activities typically generate high volumes of waste, including hazardous waste. The largest waste streams derive from the extraction or processing of minerals and comprise overburden, rock waste, and tailings. These waste streams can contain toxic and naturally occurring heavy metals and minerals mobilized by mining, such as asbestos and antimony, aluminum, arsenic, cadmium, chromium, copper, iron, lead, manganese, mercury, and thallium.
Waste from mining activities may contaminate surface water, groundwater, and seawater (see also topic 14.7 Water and effluents), as well as food sources. Waste also has negative impacts on human health (see also topic 14.10 Local communities) and animal and plant species (see also topic 14.4 Biodiversity). Land use for waste storage, along with soil contamination, leads to erosion and loss of productive land, which can further have effects on local communities’ livelihoods. The waste impacts from mining activities can depend on an organization’s approach to waste management, regulations, application of technologies, and the availability of recovery and disposal facilities near mine sites.
Mining activities often require using and storing hazardous materials, such as chemicals, for mineral processing. These materials can be released into the environment during exploration, extraction, processing, and transport. Hazardous materials can accumulate and remain in the environment beyond the life of a mine. There are specific concerns regarding the use of cyanide in processing minerals such as gold and silver, which, when improperly used, stored, or disposed of, can have negative impacts on human health and the environment (see also topic 14.15 Critical incident management). Mercury can be produced as a by-product when processing ores, potentially releasing toxic vapors. While most mining organizations no longer use mercury to extract gold, it is still used by many artisanal and small-scale operators (see also topic 14.13 Artisanal and small-scale mining).
Overburden from surface mining is usually stored in overburden emplacement facilities or dumps on adjacent land until the pit is backfilled or the overburden dump is stabilized and revegetated. These dumps require physical and chemical stabilization to avoid failures, which can have impacts on the environment and the safety of people. Overburden can also contribute to the formation of highly acidic water rich in heavy metals, known as acid mine drainage, which can seep into the environment.
Rock waste is usually managed in heaps or disposed of in waste rock dumps or former open-pit operations and can generate dust (see also topic 14.3 Air emissions). Tailings, a by-product of the processing of minerals, are often treated and discarded into ponds, filtered, stored in heaps, or disposed of in underground voids. Runoff from tailings and tailings facility failures can cause widespread environmental contamination and pose risks to the health, safety, and livelihoods of local communities (see also topic 14.6 Tailings).
The amount of waste produced by mining activities depends on the type of mineral extracted and the ore grade. Generally, surface mining produces more waste than underground mining due to the possibility of obtaining lower-grade sediments and rocks from which the mineral is extracted. Waste from mining activities often requires management beyond the productive phase of a mining operation, including long-term aftercare. Closure can also yield significant waste, for example, from decommissioned processing plants and other facilities (see also topic 14.8 Closure and rehabilitation).
Typical waste generated by mining operations comprises oils, chemicals, tires, e-waste, used catalysts, solvents, various industrial byproducts, packaging materials, and construction debris. Mining organizations may also need to manage substantial domestic waste at mine camps or in dedicated mining towns.
Box 5. Circular economy
The mining sector is both a supplier of materials and a significant user of natural resources, materials, and products. Mining organizations are increasingly incorporating circularity measures throughout the value chain. This approach can help reduce the requirement for raw materials, minimize waste generation, and repurpose waste for productive purposes, all contributing to improved resource efficiency. Mining organizations can repurpose tailings and waste rock for uses such as backfill, landscaping, and construction materials. They can also implement processes for treating and recycling process water, enabling its reuse in mining operations. Many circularity measures can be designed in collaboration with and for the benefit of local communities.
Reusing and recycling metals can significantly contribute to the circular economy, as many metals can be melted and reused infinitely. Recycling metals can also be less energy-intensive than extracting and processing virgin materials (see also topic 14.1 GHG emissions). Some mining organizations are already transitioning to more circular business models, expanding their activities from the primary extraction of minerals to metals recycling. Circularity measures can be reported using GRI 306: Waste 2020, and the use of materials is addressed in GRI 301: Materials 2016.

10 The additional sector recommendations under Disclosures 306-3, 306-4, and 306-5 ask to report a breakdown of total weight of tailings produced. The management of tailings facilities is reported in topic 14.6 Tailings.
Topic 14.6 Tailings
Tailings are a by-product of mining that need management throughout the life of a mine and beyond closure. Poor design or management of tailings facilities can, at worst, lead to catastrophic failures with lasting impacts on workers, local communities, and damage to the environment, natural resources, and infrastructure.
Tailings are generated as a by-product of mining and are usually one of the largest waste streams related to mining operations (see also topic 14.5 Waste). Often contained in the form of liquid slurry, tailings consist of processed material usually mixed with chemicals left over when separating minerals from rock or soil.
Tailings are often treated and stored in surface tailings facilities, filtered and dry-stacked, or used to fill underground voids. Surface tailings are contained by dams or disposed into decommissioned open pits and can cover vast areas. Other disposal methods, such as riverine, lake, and submarine tailings disposal, are still in use by the sector. However, these methods are widely discouraged due to the significant potential impacts on the environment and health of local communities from, for example, elevated levels of metals present in tailings (see also topic 14.10 Local communities).
Tailings containing heavy metals, cyanide, chemical-processing agents, or sulfides can pose a health risk when released into the environment. Catastrophic failures of tailings facilities, including dams, can pose detrimental risks to the safety and well-being of workers and local communities. At worst, failures can lead to loss of life and the destruction of whole communities (see also topic 14.15 Critical incident management). Further impacts include damage to infrastructure, natural resources, and the activities of other sectors, ultimately disrupting lives and livelihoods. Failures of tailings facilities result from, for example, inadequate water management, overtopping, foundation or drainage failure, erosion, and earthquakes. Extreme weather events due to climate change pose additional challenges to the long-term management of tailings (see also topic 14.2 Climate adaptation and resilience).
Runoff from tailings can contaminate groundwater, surface water, and seawater. Contaminated water sources cause damage to ecosystems, species, and agricultural operations, affecting local communities’ health and livelihoods (see also topic 14.7 Water and effluents). Dry tailings can also generate dust (see also topic 14.3 Air emissions). Inefficient processing of metal ores can spur re-encroachment and re-mining of tailings by artisanal and small-scale operators, which can mobilize toxic tailings into the environment (see also topic 14.13 Artisanal and small-scale mining).
Tailings management and storage options depend on and can be altered by various factors. These factors can include the presence of local communities, distance to areas of biodiversity importance, seismicity, the amount and seasonal distribution of rainfall, and local topography. Based on its context, each facility requires unique design and technical considerations to minimize risks to people and the environment throughout the tailings facility lifecycle, including closure and post-closure (see also topic 14.8 Closure and rehabilitation). The design is expected to be monitored, evaluated, and updated regularly, according to findings from reviews, risk assessments, and whenever there are material changes [134].
Organizations utilize site-specific plans on emergency preparedness and response to identify hazards, prepare for and assess their capacity to respond to emergencies, and anticipate long-term remediation. Alongside regular testing and updates, the plan requires active involvement with various stakeholders who could be affected, such as workers and local communities. This includes collaboration with public sector agencies, first responders, local authorities, and institutions to mitigate the potential repercussions of a failure.

Topic 14.7 Water and effluents
Recognized as a human right, access to fresh water is essential for human life and well-being. The amount of water withdrawn and consumed by an organization and the quality of its discharges can have impacts on ecosystems and people. This topic covers impacts related to the withdrawal and consumption of water and the quality of water discharged.
Mining can have significant impacts on water availability and quality, resulting in long-term consequences on biodiversity, human health and development, and food security (see also topics 14.4 Biodiversity, 14.10 Local communities, and 14.11 Rights of Indigenous Peoples). Impacts on water occur throughout the life of a mine and beyond closure.
Mining organizations use water throughout their operations, including mineral extraction, processing, cooling, dust suppression, and the transportation of ore and waste in slurries. Mining activities can reduce water availability for local communities and other water users, potentially affecting people’s right to clean drinking water. In areas where water is collected manually, reduced access to water can have disproportionate impacts on women and girls, who are typically responsible for this task [141].
The amount of water needed for mining operations depends on operational efficiency and mining methods. The total volume of freshwater withdrawn for mining operations can also vary according to an organization’s ability to substitute freshwater, the quality of water required, characteristics of local water resources, and recycling infrastructure.
Mining organizations can improve local communities’ access to freshwater by bolstering water and sanitation infrastructure and improving water quality, for example, by treating naturally occurring acid rock drainage. Mining organizations can also influence hydrology and have impacts on the livelihoods of local communities by altering groundwater levels, shifting river flow regimes, and using dams for freshwater needs in mining activities. In areas already facing water stress, mining operations can aggravate the problem by reducing water accessibility for other users and intensifying competition for water. These impacts can exacerbate tensions between and within other sectors or local communities, especially in cases where water rights and regulations are poorly managed or enforced.
The impacts of mining activities on the quality of surface water, groundwater, and seawater can be due to water discharge and runoff, heavy metal contamination, spills, leaks or leaching of chemicals, and the failure of tailings facilities (see also topic 14.5 Waste and 14.6 Tailings). Acid mine drainage can be one of the most significant water impacts from metal mines, occurring when water and oxygen react with rocks containing sulfur-bearing minerals, forming an acidic runoff. Underground operations might also disrupt or contaminate aquifers.
Contamination risks can be higher when mining occurs in areas with frequent heavy rainfall events, which can cause flooding and make the containment of effluents more challenging. The level of water treatment and water quality standards applied to effluent discharges, as well as the sensitivity of the local ecosystem, can affect the impact that mining organizations have on the receiving waterbody.
Droughts, floods, and other extreme weather events due to climate change pose more frequent challenges to water availability and quality (see also topic 14.2 Climate adaptation and resilience), requiring collaborative approaches by the mining sector to prevent or mitigate impacts on local communities [153].

Topic 14.8 Closure and rehabilitation
At the end of commercial use, organizations are expected to close assets and facilities and rehabilitate operational sites. Impacts can occur during and after closure. This topic covers an organization’s approach to closure and rehabilitation, including how the organization considers the impacts on the environment, local communities, and workers.
The aim of closure is to return land disturbed by mining to a physically, biologically, and chemically stable condition. When implemented successfully, it enables ecosystem restoration, minimizes long-term pollution, protects local water supplies, ensures public safety, and provides communities with productive land wherever possible. This process is expected to result in a healthy and functioning ecosystem that is compatible with planned post-mining land use, compliant with regulatory requirements, and considerate of the needs and livelihoods of local stakeholders. Closure planning should start at the project design phase and be updated regularly throughout the mine lifecycle. This can help mitigate impacts on the environment and people while integrating opportunities for reclamation concurrent with mining operations.
When not managed adequately, the closure of a mine can result in various environmental impacts, including the contamination of surface water and groundwater, soil contamination from overburden heaps, changes to landforms, and disturbance to biodiversity (see also topics 14.4 Biodiversity, 14.5 Waste, and 14.7 Water and effluents). The presence of, or contamination by, hazardous materials can result in long-lasting health and safety impacts on people (see also topic 14.10 Local communities). Failure to rehabilitate sites can also render land unsuitable for other productive purposes, such as agriculture, leading to the potential loss of livelihoods.
Closure activities can include:
- stabilization of open-pit or underground workings to prevent subsidence and erosion of mine-pit benches;
- decommissioning of processing facilities, equipment, and other infrastructure;
- removal of workers’ facilities and camps;
- land reclamation and rehabilitation, including management of topsoil, waste rock stockpiles, and overburden heaps to control erosion and land degradation, and foster ecosystem restoration;
- closing and sealing waste, including tailings, facilities (see also topic 14.6 Tailings);
- post-closure environmental and socioeconomic monitoring to ensure that post-closure objectives are being achieved; and
- remediation actions identified through monitoring activities.
Mining organizations can implement closure and rehabilitation activities progressively during the operating life of a mine by, for example, backfilling and revegetating unused areas as operations move to other zones.
Although closure and rehabilitation may offer new employment opportunities, cessation of mining operations also leads to unemployment when workers are no longer essential. When a mine closes, it can also result in job losses for the mine’s suppliers. In locations where the mine has been the primary economic driver by providing employment, income, tax revenue, community development, and other benefits, closure can leave local communities to face economic downturns and social disruption.
The impacts of mine closure can be exacerbated if there is insufficient notice or inadequate planning for economic revitalization and social transition. Closed or abandoned mine sites can leave a long-lasting legacy of environmental issues and financial burdens for communities and governments, unless there are assigned responsible parties or allocated funds to cover the costs of mine closure and post-closure activities (see also topic 14.9 Economic impacts). Mining organizations can collaborate with local communities, governments, unions, and workers to mitigate negative impacts and work towards a sustainable post-mining economy. This can be done by, for example, reskilling and retraining workers, offering worker transfer programs and relocation assistance programs (see also topic 14.17 Employment practices), and consulting communities, including women, on closure plans (see also topic 14.10 Local communities). Closure planning often starts in the early phases of a mine’s life cycle, becoming more detailed and responsive as the closure date approaches.
Many jurisdictions require organizations to make financial provisions, or assurances, for long-term costs associated with mine closure and rehabilitation when developing closure plans. These assurances are intended to cover the total estimated cost of closure activities and post-closure monitoring to account for social and environmental legacy impacts that can occur after closure [157].
Assurances can be in the form of various financial instruments, such as cash deposits, bank guarantees, surety bonds, trust funds, or other third-party-held assets, all designed to ensure the fulfillment of closure obligations.
Organizations can conduct periodic reviews and update costs to account for operational changes during the life of a mine and their effect on the cost of closure. However, closure costs are often misunderstood, poorly regulated, or underestimated, resulting in insufficient financial assurances to cover the actual closure costs. Providing transparency over these provisions can improve the relationship between mining organizations and stakeholders, including governments.

Topic 14.9 Economic impacts
An organization’s impacts on the economy refer to how the value it generates affects economic systems, for example, as a result of its procurement practices and employment of workers. Infrastructure investments and services supported by an organization can also have impacts on a community’s well-being and long-term development. This topic covers economic impacts at local, national, and global levels.
Mining activities can be an important source of investment and income for local communities, countries, and regions. Mineral extraction offers considerable opportunities for producing countries and their communities to gain lasting economic benefits, which, if well managed, can transform national economies, reduce poverty and inequality, and improve people’s well-being. Economic contributions can manifest locally through procurement spending, capacity building, or employment provision, and at national, subnational, or regional levels through taxes and royalties (see also topic 14.23 Payments to governments).
Impacts vary according to the scale and duration of operations, interactions with other economic activities, the effectiveness of resource governance by local and national governments, and local procurement and employment practices used by the organization. At a global scale, the sector’s contributions are prevalent through, for example, the provision of minerals for the low-carbon transition, essential infrastructure and buildings, and food production.
The economic impacts of mining vary depending on the specific phase of the mining project. During mine development, infrastructure investments are at their peak, procurement of goods and services are high, and many workers are needed. When the mine is in operation, economic impacts are mainly generated through procurement spending, employment, community investments, taxes, and other payments to governments. Mine closure and post-mining phases require economic restructuring, characterized by out-migration, reduced government revenues, and a limited need for infrastructure, goods, and services.
Through local procurement, mining organizations can foster employment and raise demand for goods and services. Workers of mining organizations and their suppliers also drive local economic growth by spending their earnings. Long-lasting positive impacts can be generated by capacity building of suppliers, along with training and skill transfer to the community. Mine construction and operation can involve the development of infrastructure, such as roads, railways, and other transport networks, that local communities can use. Production linkages with other sectors can also drive economic diversification and community development.
The extent to which local communities benefit from mining activities depends on their existing development and industrialization levels, their capacity to provide qualified workers to meet new employment opportunities, and the commitment of organizations in the sector to train local workers. The net employment impact of mining also depends on how existing jobs in other sectors are affected and the organization’s employment practices (see also topic 14.17 Employment practices). For example, using a fly-in/fly-out work arrangement to supply workers can reduce the employment opportunities available to local communities, detracting from the potential economic benefits at the local level. In places where women are traditionally responsible for meeting the subsistence needs of families and jobs are mostly occupied by men, this can result in increased domestic and community-based workload for women. These impacts can exacerbate economic disparities and gender inequalities, especially if benefit-sharing from mining is separated from the local context and community needs (see also topic 14.10 Local communities).
Changes in technology in industrial-scale mining, such as the increased use of automation and robotics, can affect economic impacts and benefit sharing. While these changes can introduce new skills and increase work opportunities for women and other underrepresented groups, they can also reduce the number of workers needed for mining activities.
Additionally, a poorly planned or executed mine closure process can generate legacy impacts with economic consequences for communities and governments (see also topic 14.8 Closure and rehabilitation).
Lasting negative impacts can be mitigated at the local level in consultation with the community. This can be achieved by incorporating inclusive development, benefit-sharing mechanisms, and impact-driven community development programs aimed at the structural transformation of local economies. Mining organizations can also promote economic inclusion by recruiting or using suppliers that recruit workers from less represented or marginalized groups, including women-owned enterprises (see also topic 14.21 Non-discrimination and equal opportunity). Extending skills development to workers who are not employees and the local community can also contribute to positive impacts and promote a just transition after a mine is closed.

Topic 14.10 Local communities
Local communities comprise individuals living or working in areas that are affected or that could be affected by an organization’s activities. An organization is expected to conduct community engagement to understand the vulnerabilities and priorities of local communities and how they may be affected by the organization’s activities. This topic covers socioeconomic, cultural, health, and human rights impacts on local communities.
Mining activities can create social and economic benefits for local communities through local procurement and employment, taxes and other payments to governments, infrastructure investments and services supported, and community development programs (see also topics 14.9 Economic impacts and 14.23 Payments to governments). However, mining activities can also trigger negative socioeconomic, cultural, health, and human rights impacts on communities near mine sites, including Indigenous Peoples, artisanal and small-scale miners, and other vulnerable groups throughout the life of a mine and beyond closure (see also topics 14.11 Rights of Indigenous Peoples and 14.13 Artisanal and small-scale mining).
Negative impacts can result from land use requirements that limit the accessibility and availability of land and natural resources, leading to the loss of tradition, culture, or cultural identity (see also topic 14.12 Land and resource rights). Mining activities can damage tangible cultural heritage, including sites and artifacts, as well as intangible forms of culture, such as lifestyles and knowledge. Other negative impacts on community health, safety, and well-being can be caused by:
- exposure to pollution, hazardous substances, and dust (see also topic 14.3 Air emissions);
- contamination of groundwater and surface water (see also topic 14.7 Water and effluents);
- traffic to and from the mine site;
- increased levels of light, noise, and vibration resulting from, for example, blasting and transportation;
- degradation of ecosystem services;
- reduced fishing and agricultural yields; and
- critical incidents such as explosions, fires, mine collapses, spills, and tailings facility failures (see also topic 14.15 Critical incident management).
Women can be disproportionately affected by the negative environmental impacts of mining. For example, the work to collect water and food by many rural communities is most often carried out by women and girls. Women are also frequently excluded from formal community consultations.
The influx of workers, job seekers, or others aiming to benefit from the economic activity of a mine can generate social disruption and greater economic inequalities within the local community. This influx can place local services and resources under pressure, induce inflation, and raise housing costs. There can also be an increase in substance abuse, gambling, and prostitution, as well as communicable diseases, which may disrupt the social cohesion of a community. These changes can have disproportionate impacts on vulnerable groups in society, such as the elderly, children, and young people. Women, in particular, are more affected due to the potential rise in sexual violence and trafficking resulting from the gender imbalance of predominantly male workers. Documented cases also show the presence of domestic and gender-based violence on mine sites and in mining-adjacent communities [185].
Mining can also trigger social conflicts, resulting in human rights impacts. When the interests of the mining organization are at odds with the interests of the local community, disagreements or grievances can escalate (see also topic 14.4 Security practices). Conflict can occur, for example, due to negative environmental impacts, inadequate engagement with the local community, uneven distribution of economic benefits, or disputes over land use and natural resources during mining and post-closure.
Mining organizations can assess impacts on communities throughout the life of a mine by undertaking environmental and social impact assessments. This can help ensure that negative impacts are identified, prevented where possible, addressed, and remedied on time. Organizations are expected to provide benefits that contribute to long-term development for local communities to balance the negative impacts of mining. For example, community development agreements often define mining organizations’ rights and responsibilities to deliver socio-economic benefits to local communities. These agreements may include obligations related to infrastructure development, land and water use, collaboration with artisanal and small-scale miners, and local procurement and employment [187]. In some cases, these agreements can be enforceable.
Meaningful engagement with local communities involves two-way communication that is transparent, proactive, inclusive, and ongoing. This approach can help alleviate tensions, improve community relations, and facilitate transparent decision-making processes, which are essential for obtaining and retaining a social license to operate. Meaningful engagement also entails consultation with local communities before making decisions, including by acknowledging the power imbalance of the mining organization with local communities and providing accessible, culturally appropriate, and gender-responsive information in the local language [173]. By including the voices of women, ethnic minorities, and other underrepresented groups in consultations, mining organizations can actively involve their community engagement processes. This ensures that the information gathered reflects local priorities and promotes the equitable distribution of benefits.
Organizations further address their negative impacts by establishing or participating in grievance mechanisms and other remediation processes tailored to community needs.
