In total, the administration projects $1.5 trillion in savings for the economy through all the regulations it plans to have terminated by end of September. The lion’s share of the expected savings stems from a single action underpinning the climate policies of Presidents Barack Obama and Joe Biden, repealing the 2009 “endangerment finding” that greenhouse gases pose a threat to human health and welfare. Trump has claimed that the emissions policies made possible by that finding would cost the economy $1.3 trillion.
