WASHINGTON (Reuters) - Joe Biden has promised sweeping measures to make the U.S. economy carbon neutral by 2050 to put the United States on a path to cut emissions as deeply as scientists say is necessary to avoid the worst impacts of climate change.

The agenda to reverse President Donald Trump's legacy of climate deregulation would likely start with some easy wins, such as rejoining the Paris Agreement, but would become more complex as his administration ventures further into regulating greenhouse gas emissions down toward net-zero.
