In a given year, the biggest banks in the U.S.–Wells Fargo, Citi, Bank of America, and JP Morgan Chase–rake in billions of dollars in fees that their customers pay to the bank they are with, and money they have to turn over if they overdraw from one of their accounts. Often, the banks then turn that money around and invest it in fossil fuels; in one of the most well-documented instances of big banks’ questionable investments, Wells Fargo poured money into companies pushing the controversial Dakota Access Pipeline.
