President Trump is heading to Charleston, West Virginia, today to hold a campaign rally and announce a massive rollback of Obama-era environmental regulations for coal-fired power plants. The deregulation will dramatically weaken President Obama’s signature Clean Power Plan, which aimed to cut carbon dioxide emissions in order to address climate change. Under President Trump’s planned deregulation, individual states will now be allowed to decide whether to curb emissions. The Washington Post reports the deregulation will mean at least 12 times more carbon dioxide will be released into the atmosphere over the next decade. The deregulation will also roll back rules aimed at reducing air pollution from the coal-fired power plants. Andrew Wheeler, the current acting administrator of the Environmental Protection Agency, is a former coal industry lobbyist.
