Mining Pollutes Remote Ecosystems

The Philippines is the world’s leading exporter of raw nickel ore and the second largest producer of the metal, a position that places the country at the centre of a global paradox. The nickel dug from its soil is essential for the batteries powering electric vehicles and renewable energy storage, yet the mining operations that extract it are causing documented harm to the very ecosystems and communities that climate action is meant to protect. Understanding this tension — between the raw materials needed for a clean energy transition and the local environmental destruction left in their wake — is essential for anyone following the real-world costs of the green economy.

Global nickel demand is expected to increase roughly 60 percent by 2040 in a scenario aligned with the Paris Agreement’s climate goals. That figure matters because it signals that the pressure on mining communities in the Philippines will not ease — it will intensify. The country already ships more than 90 percent of its nickel ore exports to China, where the raw material is processed into battery-grade metal. A smaller but rapidly growing share — nickel ore exports to Indonesia increased more than 4,000 percent from 2023 to 2024 — reflects how Indonesian smelters facing shortages have turned to Philippine supply. For readers, this means the environmental and social footprint of nickel mining is not a distant concern; it is directly tied to the global supply chain for the devices and vehicles many now consider essential. For a deeper look at how industrial activity affects marine ecosystems, see our coverage of heavy metal contamination in Filipino waters.

What nickel mining does to ecosystems and communities

The core issue is straightforward: nickel laterite deposits, which account for about 70 percent of the world’s nickel reserves, are extracted through open-pit mining that strips away topsoil and vegetation. In the Philippines, most mining occurs in the Caraga Region on Mindanao and on the island of Palawan. Climate Rights International interviewed 57 residents and workers living near nickel mines in the Caraga Region who reported increased vulnerability to the climate crisis because of mining-related deforestation and pollution, the destruction of fishing and farming livelihoods, inadequate compensation for land, increased rates of food insecurity, water pollution threatening access to drinking water, health problems related to mining and dust, and new difficulties accessing education. Multiple individuals, including a prominent anti-mining activist and a local politician, told researchers that bounties had been put on their heads due to their anti-mining positions.

On Palawan, known as the Philippines’ “last frontier” for its untouched natural beauty and rich marine ecosystems, the damage is visible. Environmental groups estimate the island may hold close to half of all the Philippines’ remaining untouched old-growth forest, as well as 30 percent of its remaining mangroves and up to 40 percent of its coral reefs. Mining operations there, including the Ipilan Nickel Corp project near Mt Mantalingahan, are among 11 active mining projects on the island that were exempted from a 2025 moratorium on mining expansion. Local communities say the mine has sent tendrils of contamination into the delicate ecosystems that surround it.

How deforestation and pollution amplify climate vulnerability

The relationship between nickel mining and climate vulnerability is not a simple one. Mining operations drive deforestation, and when forests and mangroves are cleared, the carbon stored in both plant matter and soil may be released into the atmosphere. This turns what was once a carbon sink into a source of emissions — a direct contradiction of the climate goals that justify the demand for nickel in the first place.

Residents in Tubajon on Dinagat Island in Mindanao 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 Super Typhoon Odette in 2021. Climate change is projected to increase the frequency of heavy rainfall in the Philippines, increasing the likelihood of flooding events that will impact lives and livelihoods. The severity of the flooding is often exacerbated by failures by mining companies to effectively manage their waste, leading to rivers choked with sediment and logs. Residents in the towns of Cantilan, Madrid, and Carmen in Surigao del Sur told Climate Rights International that they are particularly concerned that flooding events are becoming more frequent and severe due to the combined impacts of mining and the climate crisis.

On Palawan, the damage extends underwater. What were once vibrant orange and delicate pink coral formations now lie buried under thick layers of mining sediment, transformed into uniform khaki-colored mounds. The reef ecosystem, once teeming with marine life, has become suffocated by red globules of nickel ore runoff that cloud the water like smoke when disturbed. Roddy Masap, a fisherman near Brooke’s Point, noticed fish disappearing from the bay about four years ago — shortly after the mine expanded and shipped out its first 50,000 tonnes of nickel ore to China. Once, a good day would bring in 40kg of fish. Now, their catch is often as little as 7kg. For a family that depends on fishing for both food and income, that difference is not an inconvenience — it is a collapse.

What gets missed in the clean energy narrative

The global push for clean energy often presents mining as a necessary trade-off — a temporary environmental cost for a long-term climate benefit. But several complications emerge when you look closely at how nickel mining actually operates in the Philippines.

The processing gap

Most of the nickel mined in the Philippines is shipped as raw ore and processed outside the country. More than 92 percent of shipments go to China, with another 5.5 percent sent to Indonesia. This means the Philippines bears the environmental and social costs of extraction — deforestation, water pollution, livelihood destruction — while the economic value of processing and manufacturing accrues elsewhere. The country exports a critical mineral but captures only a fraction of its value chain.

The biodiversity blind spot

Analysis produced for the Guardian by academics found more than 3,267 instances of mining within key biodiversity areas globally, accounting for nearly 5 percent of the sector’s footprint. In the Philippines, mining occurs in locations like the tabletop tepuis mountains of Venezuela — earthbound “islands” more than 1,000 metres high where unique species have evolved in isolation over millennia. When a mine opens in such an area, the species loss is irreversible. The argument that mining is a temporary disturbance ignores the permanent elimination of biodiversity that took millions of years to develop.

The health denial

Mining companies have told local people that nickel extraction will not affect their health. In a statement reported by the Guardian, one company said: “Laterite is not considered toxic and is not the cause of losses for farmers or fishermen, nor does it have any negative effects on human health.” While nickel laterite is not considered toxic in its undisturbed form, when processed or washed into waterways it can release nickel and chromium. Residents near stockpiles report painful, itchy rashes after contact with the silt, and children have developed long-term coughs since the stockpile was built. The distinction between undisturbed laterite and processed runoff matters, but it is not one that communities living downstream can afford to rely on.

What can be done — and what is being done

The situation is not without responses, though the scale of the challenge is significant. Several avenues exist for those looking to understand or act on the issue.

Trace the supply chain

By analyzing customs records for shipments of nickel ore, the organisation Empower was able to document 3,473 shipments of nickel ore to eight countries, 65 distinct exporters, and 110 importers from April 2020 to December 2024. This kind of transparency is rare. For consumers and investors, the first step is knowing where the nickel in a product comes from. Battery manufacturers and automakers are increasingly being asked to disclose their supply chains, and several have committed to sourcing only from certified responsible mines. The practical step for an individual is to look for companies that publish third-party audits of their mineral supply chains.

Support community-led monitoring

Residents in mining areas have documented their own evidence — water samples, photographs of sediment runoff, records of fish catches. Organisations like Climate Rights International and Empower work with local communities to gather testimony and data. Supporting these groups, either through direct donations or by amplifying their findings, helps ensure that the voices of affected communities are not drowned out by industry narratives. The process is straightforward: identify a credible organisation working on mining accountability in the Philippines, review their published reports, and share them within your network.

Advocate for domestic processing

One structural fix that would shift the balance is requiring or incentivising the processing of nickel ore within the Philippines rather than exporting raw material. This would keep more economic value in the country and allow for stricter environmental oversight of processing facilities. Several policy proposals have been floated, but none have been implemented at scale. For readers interested in policy advocacy, tracking the legislative progress of bills related to mining taxation and local processing requirements is a concrete starting point. For a broader look at how industrial waste affects Philippine ecosystems, see our article on rivers choked by factory waste.

Understand the moratorium exemptions

The 2025 moratorium on mining expansion in Palawan exempted 11 existing active projects. This means that while no new mines can open, the ones already operating — including the Ipilan Nickel Corp project near Mt Mantalingahan — can continue and even expand. For anyone tracking this issue, the key question is whether the moratorium will be renewed and whether the exemptions will be narrowed. Future-phase information: advocacy groups are pushing for a complete ban on mining in Palawan’s remaining old-growth forests and key biodiversity areas, but no such legislation has passed as of the latest reporting.

Frequently asked questions about nickel mining in the Philippines

Closing

The nickel in a single electric vehicle battery may have travelled from a mine in the Caraga Region or Palawan, through a Chinese smelter, and into a factory on another continent. Along that route, it leaves behind deforestation, polluted water, collapsed fisheries, and communities that report being threatened for speaking out. The clean energy transition will not succeed if it replicates the same patterns of extraction and harm that defined the fossil fuel era. The question is whether the global demand for nickel can be met in a way that does not sacrifice the ecosystems and people on the front lines of extraction.
