Wall Street's major Financial Institution Group is to blame for funding the massive-emitting Bitcoin mining industry, according to a new report from Greenpeace USA. Greenpeace claims that large Financial Institution Groups perpetuate the ecological threat the industry represents by creating economic incentives to support Bitcoin mining. The report names Trinity Capital, Stone Ridge Holdings, BlackRock, Vanguard, and MassMutual as the top five funders of carbon pollution from Bitcoin mining companies. According to the report, they collectively emit more than 1.70 million metric tons of carbon dioxide by 2022, equivalent to the annual electricity emissions of more than 335,000 U.S. households. Greenpeace said that bitcoin mining has developed into a large commercial industry, and companies need to obtain large amounts of capital to build facilities and purchase computing equipment.
