As The Guardian reported in partnership with the Center for Media and Democracy in July, Manchin himself founded a private coal brokerage in 1998 called "Enersystems." Though currently run by his son, Manchin still owns as much as a $5 million stake in the company, raking in $500,000 of income from it in 2020 alone. As of late 2019, Manchin was by far the most invested of any senator in "dirty energy."
Manchin serves as chair of the Senate Energy and Natural Resources Committee, which oversees the coal industry as well as "global climate change." As Sludge reported in early July, Manchin told the 2021 annual conference of the Edison Electric Institute in June that "coal-fired plants are being unfairly targeted by environmentalists."
