President Trump has also removed California's ability to set more stringent standards on emissions.
President Donald Trump nixed nearly 100 environmental regulations during his first three years in office, effectively rolling back much of his Democratic predecessor’s environmental legacy.
The president rolled back more than 90 environmental rules and regulations, The New York Times reported in December. The NYT relied on an analysis from Harvard Law School, Columbia Law School and other sources to keep tabs on Trump’s numbers during his time in office.
Trump has fully eliminated 25 rules designed to rein in air pollution and emissions, as well as 19 that regulate energy producers’ ability to drill and extract oil and gas. Trump uses a “one-two punch,” according to Caitlin McCoy, a fellow at Harvard Law School who tracks such measures.
One of Trump’s biggest accomplishments in the early going was replacing former President Barack Obama’s Clean Power Plan, which required states to make deep cuts to power sector emissions. The U.S. Supreme Court issued a stay on the CPP’s implementation in 2016.
