Tracking the environmental rules reversed by trump

By Nadja Popovich
Shortly after coming into office three years ago, President Trump began to undo many of the major climate and environmental policies put in place by his predecessor, Barack Obama, calling them unnecessary and harmful to industry.
Within a week his inauguration, Mr. Trump had revived a pipeline project rejected by Mr. Obama and expedited review of another. He also moved quickly to begin unwinding the Obama-era Clean Power Plan, which required states to cut planet-warming carbon dioxide emissions from power plants, and to quit the Paris Agreement on climate change, under which nearly 200 nations pledged to significantly reduce their output of greenhouse gases.
The Times climate team chronicled this flurry of reversals, one by one. And, for Mr. Trump’s first 100 days in office, we pulled together each of these early actions into a single list, so readers could better understand the scope of the president’s deregulatory agenda. At the time, we counted 23 rules being rolled back.
We’ve been tracking them ever since. Today, our tracker counts nearly 100 rules and regulations reversed or on the way out under Mr. Trump. More than 60 rules have been officially revoked or otherwise undone, with an additional 34 rollbacks still in progress, including rules governing clean air, water and toxic chemicals.
You can read more about each of them on our tracking page. We’ll be updating it soon with several more entries that readers identified.
