Dear Mr. Corbat,

Each year, mining companies dump over 180 million tonnes of hazardous mine tailings directly into oceans, rivers and lakes; this is more than the US puts into its landfills each year.  Mine tailings can contain dangerous chemicals including arsenic, lead, mercury, and cyanide. This practice devastates the environment, and the communities that depend on it for food, clean water and livelihoods.

Citigroup is a shareholder in Nussir ASA and Nordic Mining ASA, which have both proposed new mines that would dump tailings directly into Norway’s majestic fjords. Citigroup is also the third largest shareholder in Highlands Pacific and St Barbara Limited, two mining firms responsible for collectively dumping more than 54 million tonnes of toxic waste into waters off the coast of Papua New Guinea, home to some of the most highly diverse coral ecosystems in the world.

Citigroup’s investment in companies that dump their mine waste into coastal waters, as well as those companies seeking to employ this practice, violates the Equator Principles, which seek to ensure that financing is provided only to projects being developed in a “socially responsible manner and with sound environmental management practices.” Submarine tailings disposal has been phased out in many parts of the world due to the often irreversible consequences.

Continued investment in the few companies that use this archaic practice is inconsistent with Citi’s Sustainable Progress Strategy goals to advance environmental and social progress and promote sustainable, pro-biodiversity investment. It is also in direct conflict with Citi’s core values of sustainability and innovation as outlined in Citi’s ‘Citizenship Approach’ and the commitments set out in the Environmental Social Policy Framework for Areas of High Caution and Special Focus, including areas of high value for conservation, cultural heritage, and Indigenous Peoples.

Nussir’s copper mine is opposed by Saami Indigenous people due to the threat it poses to their traditional reindeer herding and fishing practices. The Saami Parliament has rejected the mine twice. In 2016, the Saami Parliament wrote Citigroup to express concern about the Nussir mine and to request it withdraw its investment.

Nordic’s Engebø mine would dump 250 million tonnes of toxic waste into the Førdefjord, a ‘National Salmon Fjord,’ connecting the open sea with a permanently-protected river and important spawning grounds for salmon, cod, halibut, and herring. The Union for Norwegian Coastal Fishermen and the Norwegian Fishermen’s Association oppose mine waste dumping in the Førdefjord, and the local tourism board has called it a “catastrophe for modern business.”

Highlands Pacific’s Ramu nickel mine is opposed by local people who have experienced contamination of coastal waters critical to cultural practice and traditional livelihoods. St Barbara’s Simberi mine also has a long track record of dumping in the South Pacific Ocean.

So far, 36 groups have joined the call for an end to the financing of mines that would use submarine tailings disposal. Continuing this harmful practice presents grave risks to people, ecosystems and the clean water we all depend on. We urge Citigroup and its global subsidiaries to sever ties to companies that dump waste into the ocean.
