During his first two months in office, President Donald Trump has rolled back key Obama-era greenhouse gas regulations. A look at some of those moves:
• In Tuesday’s executive order, Trump instructed the Environmental Protection Agency to reverse course on the Clean Power Plan, which aimed to cut emissions from existing coal- and gas-fired power plants.
• Earlier this month, Trump took aim at fuel economy standards that would cut tailpipe CO2 emissions from personal cars and trucks, instructing EPA Administrator Scott Pruitt to reopen a review of fuel standards.
• Earlier this month, the EPA announced it was withdrawing a rule that required existing oil and gas well operators to provide information about methane emissions.
• As one of its first actions, the White House issued a freeze on all new or pending regulations, which put on hold several energy-efficiency standards that cover products like portable air conditioners and commercial boilers. The rules have not been officially undone, but remain in regulatory limbo.
