Nickel mining in the Philippines has turned the Caraga Region into a global hub for the mineral used in electric vehicle batteries, but for the communities living near the mines, the cost has been measured in polluted water, lost livelihoods, and a growing sense of abandonment. The Philippines is the second largest producer of nickel and the world’s leading exporter of raw nickel ore, a material essential for the batteries powering the global energy transition. Yet a 125-page report by Climate Rights International, based on interviews with 57 residents and workers in Dinagat Island and Surigao del Sur, documents a pattern of environmental destruction and human rights abuses that raises serious questions about who truly benefits from this industry.
These numbers only hint at the scale of the problem. The Caraga Region alone hosts 23 operating nickel mines, more than any other region in the Philippines, and the environmental footprint extends far beyond the mine pits. For the people who live there, the consequences are not abstract statistics — they are the daily reality of trying to farm, fish, and raise families in landscapes transformed by mining operations. Understanding how this situation developed, and what it means for the communities caught in the middle, requires looking at the specific ways mining reshapes both the environment and the social fabric of affected areas. For a broader look at how industrial pollution affects waterways across the country, you can read about medical waste messes in the Philippines that pollute waterways.
How nickel mining undermines food security and health
The most immediate consequence of unchecked nickel mining is the destruction of the natural resources that communities depend on for survival. In Dinagat Island and Surigao del Sur, fisherfolk interviewed by Climate Rights International described how water pollution from mining areas has harmed fisheries and made it more difficult, if not impossible, for people to continue fishing. This is not a marginal issue — for coastal communities, fishing is not just a livelihood but a primary source of protein and income. When the fish disappear, families face a direct hit to both their nutrition and their earnings.
Farmers face a similar predicament. Across the region, they described how mining has made farming much more difficult, and in some cases impossible, due to the loss of their farmland, frequent flooding of fields from mining-choked rivers, and dust and water pollution from nearby mining activities. Rice, the most important staple food of the region, is particularly affected because it is grown in lowland areas that are susceptible to flooding and siltation. The result is a growing food insecurity that one resident, Analiza, a 46-year-old mother of four from Tubajon on Dinagat Island, summed up bluntly: “It is now hard to feed my family. We are hungry most of the time.”
Health concerns compound the economic losses. Residents living near nickel mines in Dinagat Island and Surigao del Sur told researchers that they are concerned that recently developed health problems, including respiratory and skin ailments, are related to pollution from nearby mines. These concerns are not unfounded. In Palawan, a separate investigation by Friends of the Earth Japan found that hexavalent chromium exceeding domestic and international environmental standards has been detected constantly during the rainy season at a fixed point in the Togpon River flowing from the existing mining concession of the Rio Tuba Nickel Mining. In September 2024, the highest concentration of this carcinogen in 15 years of water quality studies was recorded. The implications are stark: indigenous peoples and farmers who depend on these rivers for their daily lives and agriculture may be adversely affected for decades to come.
What gets missed in the conversation about mining and climate
The dominant narrative around nickel mining positions it as a necessary part of the green energy transition — after all, nickel is a key component in batteries for electric vehicles and energy storage. But this framing often overlooks the local environmental costs that undermine the very climate goals these technologies are meant to serve. The picture is more complicated than a simple trade-off between clean energy and local harm.

| Impact | Direct Effect | Climate Consequence |
|---|---|---|
| Deforestation | Loss of forests and mangroves | Carbon sink becomes carbon source; reduced storm surge protection |
| Water Pollution | Siltation and runoff contaminate drinking water | Communities more vulnerable during extreme weather |
| Livelihood Loss | Farming and fishing become impossible | Food insecurity increases; families cannot afford to relocate |
| Health Impacts | Respiratory and skin ailments | Reduced capacity to cope with climate shocks |
One of the most overlooked dimensions is how mining operations actively increase climate vulnerability for local communities. Nickel mining drives deforestation and the loss of species that provide climate resilience, such as terrestrial and mangrove forests. When deforestation occurs, carbon stored in both plant matter and soil may be released into the atmosphere, turning a carbon sink into a source of emissions. Residents in Tubajon on Dinagat Island described how the loss of forests and mangroves due to mining operations and mining-related pollution has made their communities more exposed to storm surges, high winds, and flooding during extreme weather events like the devastating Super Typhoon Odette in 2021. The very industry that is supposed to help mitigate climate change is, in some places, making people more vulnerable to its effects.
Another dimension that rarely surfaces in public discussion is the role of corporate accountability — or the lack of it. Despite ongoing complaints from local communities, those directly impacted face a lack of accountability and remedies for the harms they have suffered. A general lack of transparency by many mining companies impacts the ability of local governments and communities to actively participate in approving mining projects or monitoring mining impacts. Some individuals in the Caraga Region and across the Philippines who have challenged mining companies have faced Strategic Lawsuits Against Public Participation (SLAPPs) that they believe are intended to silence their activism. The Philippines is considered the most dangerous country in Asia to be a land and environmental defender, and multiple people interviewed by Climate Rights International reported knowing individuals whose killings they believe were linked to their anti-mining activities or who had experienced attacks, harassment, or intimidation themselves.

What can be done about mining pollution in the Philippines
The situation is not without potential remedies, but they require action from multiple fronts — government regulators, mining companies, and the international corporations that buy Philippine nickel. The path forward involves both stopping further damage and addressing the harm already done.
Strengthening enforcement of existing regulations
Climate Rights International has called on the Philippines government, including the Department of Environment and Natural Resources and the Mines and Geosciences Bureau, to fully enforce and strengthen laws and regulations to minimize the impacts of nickel mining on communities. This is not about creating new rules from scratch — it is about making existing ones work. The report specifically recommends that the government urgently stop the permitting of new mines until the industry meets domestic and international environmental standards, including in the management of mining waste. For communities already affected, this pause would provide a window to assess cumulative impacts rather than approving projects one by one without considering how they compound each other.
Holding mining companies accountable for remediation
Nickel companies should take immediate steps to remedy water and air pollution caused by their operations and properly dispose of mine waste to minimize environmental pollution. This is not a vague suggestion — it means specific actions like treating contaminated water before it enters rivers, rehabilitating deforested areas, and compensating communities for lost livelihoods. The fact that hexavalent chromium has been detected in the Togpon River for 15 years without effective mitigation suggests that voluntary measures have not worked. Civil society groups, including 86 organizations from 39 countries, have submitted a petition calling on Sumitomo Metal Mining Co. to immediately suspend the Coral Bay Nickel Processing Project and the Rio Tuba Nickel Mining Project in Palawan until effective and publicly verifiable countermeasures are developed and implemented.
Leveraging the influence of international buyers
Electric vehicle and battery companies that directly or indirectly source nickel from the Philippines — including Tesla and Toyota, which use battery materials from Sumitomo Metal Mining — should use their leverage to ensure suppliers end and remedy rights abuses, clean up water and air pollution, and protect the rights of environmental and human rights defenders. As Leon Dulce of LRC-FoE Philippines put it, “electric vehicle corporations like Panasonic and Tesla are profiting from CBNC-SMM’s nickel value chain while host communities in the Philippines are left to suffer miniscule royalties that pale in comparison to the damages caused by hexavalent chromium pollution.” These companies have the market power to demand better practices from their suppliers, and increasingly, international legal frameworks such as the UN Guiding Principles on Business and Human Rights are being recognized by courts as requirements that governments and corporations must observe.
Addressing the emerging threat of expanded mining
With expectations of growing global demand for nickel in the context of efforts toward a decarbonized society, mining operations have begun to expand in the region. However, as no effective pollution mitigation measure has been taken to date, it is highly likely that similar water pollution will spread to other rivers. This is not a future hypothetical — it is a predictable outcome based on 15 years of data. The expansion plans should be halted until the existing pollution problems are solved, not accelerated in the name of climate action.
