Philippines Mining Pollution Truth

The Philippines is the world’s largest exporter of raw nickel ore, shipping out nearly US$1 billion worth in 2024 alone. That figure reflects a global rush for minerals essential to electric vehicle batteries and clean energy infrastructure, but it also points to a less visible cost borne by the communities living closest to the mines. For residents in mining provinces like Surigao del Sur and Dinagat Islands, the trade-off has meant degraded farmland, polluted water sources, and a growing sense of insecurity.

These numbers help explain why the Philippines finds itself at the centre of a difficult conversation. The country holds some of the world’s largest laterite nickel deposits — which account for about 70 percent of global nickel reserves — and demand is only expected to climb. But the environmental and social consequences documented by researchers, journalists, and residents raise questions about who benefits and who bears the risk. For a deeper look at how industrial activity affects waterways, you can read our earlier piece on protecting Philippine rivers from pollution.

What nickel mining actually involves — and what it displaces

The method used in Surigao del Sur — open-pit strip mining — is not subtle. It involves clearing every layer of vegetation and soil to reach the nickel-bearing ore beneath. The result is a landscape that can take decades to recover, if it recovers at all. Residents in Tubajon on Dinagat Island described how the removal of mangroves and forests has made their communities more vulnerable to extreme weather. Climate change is projected to increase the frequency of heavy rainfall in the Philippines, meaning that flooding events are becoming more frequent and severe due to the combined impact of mining and a changing climate.

For fishing communities, the changes have been immediate. In Palawan, a fisherman named Masap told reporters that fish began disappearing from the bay about four years ago — shortly after the mine expanded and shipped its first 50,000 tonnes of nickel ore to China. Where a good day once brought in 40 kilograms of fish, the catch now often falls to just 7 kilograms. The mining company has stated that laterite is not toxic and is not the cause of losses for farmers or fishermen, but residents point to the visible sediment plumes and altered water quality as evidence to the contrary.

The human cost: health, intimidation, and a 15-year legal battle

The social toll documented by investigators goes beyond environmental damage. Climate Rights International interviewed 57 residents and workers near nickel mines in the Caraga Region, who reported a range of harms: increased food insecurity, water pollution affecting drinking water, health problems linked to mining dust, and difficulty accessing education. Some also described a climate of fear. Multiple individuals, including a prominent anti-mining activist and a local politician, told researchers that bounties had been placed on their heads because of their opposition to mining.

That case, documented by Global Witness, began when Nick Iriberri was just five years old, making him the youngest plaintiff in a lawsuit accusing Marcventures Mining and Development Corporation of environmental destruction and human rights violations. The case was filed in Cantilan, Surigao del Sur, and by law should have been resolved within a year. Nick was 20 by the time the court finally reached its verdict — and it found in favour of the company. The report alleges that the company used political connections to sidestep regulations and evade accountability, though the company has denied wrongdoing.

The broader pattern is one of extraction without adequate oversight. By analyzing customs records, the organisation Empower documented 3,473 shipments of nickel ore from April 2020 to December 2024, involving 65 distinct exporters and 110 importers. Of those shipments, 92 percent went to China and 5.5 percent to Indonesia. The Philippines processes very little of its own nickel; most is shipped as raw ore, meaning the value-added processing — and the jobs that come with it — happens elsewhere.

What gets missed in the clean energy narrative

The global push for electric vehicles and renewable energy storage has created a surge in demand for nickel. According to modelling aligned with the Paris Agreement, global nickel demand is expected to increase by roughly 60 percent by 2040. EV batteries alone are expected to account for more than half of that growth by 2030. The logic seems straightforward: mining nickel enables the transition away from fossil fuels. But the reality on the ground complicates that picture.

One of the most striking findings from recent research is the scale of mining’s overlap with biodiversity. Analysis produced for the Guardian found more than 3,267 instances of mining within key biodiversity areas globally, accounting for nearly 5 percent of the sector’s footprint. In Palawan — known locally as “the last ecological frontier” — environmental groups estimate the island holds close to half of all the Philippines’ remaining untouched old-growth forest, 30 percent of its remaining mangroves, and up to 40 percent of its coral reefs. Yet it is also home to 11 active mining projects that were exempted from a 2025 moratorium on mining expansion.

The processing gap

Another dimension that often goes unmentioned is where the ore actually gets processed. More than 90 percent of Philippine nickel ore is shipped to China, where it is smelted into nickel pig iron or battery-grade nickel. This means the Philippines bears the environmental cost of extraction — deforestation, siltation, water pollution — while the economic benefits of processing and manufacturing accrue elsewhere. Nickel ore exports to Indonesia increased more than 4,000 percent from 2023 to 2024, as Indonesian smelters faced shortages, further highlighting how dependent the global supply chain is on raw ore from a small number of source countries.

Who is in the supply chain

Research by Global Witness suggests that some of the world’s largest car companies — including Tesla, Volkswagen, Mercedes, BMW, and Audi — likely source battery components using nickel from Philippine mines, including the Marcventures mine at the centre of the 15-year legal case. This means that the clean energy products consumers buy may be linked to the same environmental and human rights concerns documented in Surigao del Sur and Dinagat Islands.

What can be done — and what is being asked

For residents and advocates, the path forward involves several concrete demands. These are not hypothetical suggestions; they reflect what affected communities have been asking for, often for years, through legal cases, protests, and international advocacy.

Stronger enforcement of existing regulations

The 2025 moratorium on new mining projects in Palawan shows that the government can act when pressure builds. But the exemption of 11 existing projects means that the most biodiverse areas remain under threat. Advocates argue that enforcement of environmental impact assessments, water quality standards, and reclamation requirements needs to be consistent and independent of political influence. The Marcventures case, which took 15 years to resolve despite a one-year legal mandate, illustrates how delays can effectively deny justice.

Accountability for human rights violations

Climate Rights International and Global Witness have documented cases of intimidation, threats, and violence against anti-mining activists. Multiple individuals told investigators that bounties had been placed on their heads. For meaningful change to occur, these cases need to be investigated independently, and those responsible must be held accountable. Without that, the climate of fear will continue to silence opposition.

Domestic processing and value capture

One structural change that could shift the balance is requiring or incentivising domestic processing of nickel ore. Currently, more than 90 percent of exports go to China as raw ore. Building local smelting capacity would create jobs, retain more economic value, and allow for tighter environmental oversight of processing. Indonesia has pursued a similar strategy with some success, though it has also faced environmental criticism. The Philippines could learn from both the opportunities and the pitfalls.

Community consent and benefit-sharing

Indigenous communities and local governments often have little say in mining decisions that affect their land and water. Free, prior, and informed consent — a principle recognised in Philippine law — is frequently ignored in practice. Strengthening this mechanism, along with transparent benefit-sharing agreements, would give communities a genuine stake in decisions about extraction on their ancestral lands.

• 1
  Push for independent monitoring

  Community-led water testing and air quality monitoring can provide evidence that holds mining companies accountable when violations occur.

• 2
  Support legal aid for affected communities

  Organisations like CRI and Global Witness provide documentation and advocacy, but local legal support is essential for cases to move forward.

• 3
  Demand supply chain transparency

  Consumers and investors can pressure car manufacturers and electronics companies to disclose where their nickel comes from and under what conditions it was mined.

Frequently asked questions about nickel mining in the Philippines

Closing thoughts

The clean energy transition will require more nickel, and the Philippines will remain a key supplier for the foreseeable future. But the current model — open-pit mining with minimal domestic processing, weak enforcement, and documented human rights abuses — is not sustainable in any meaningful sense of the word. Communities in Surigao del Sur, Dinagat Islands, and Palawan are not asking for mining to stop entirely. They are asking for rules to be followed, for their safety to be protected, and for a fair share of the value their land produces. Those are not unreasonable demands. If this was useful, you might also want to read how dirty water hurts Filipino families.
