WASHINGTON: The administration of President Donald Trump on Thursday announced the repeal of a scientific finding that greenhouse gas emissions endanger human health, and eliminated federal tailpipe emissions standards for cars and trucks. It is the most sweeping climate change policy rollback by the administration to date, after a string of regulatory cuts and other moves intended to unfetter fossil fuel development and stymie the rollout of clean energy.

A White House official confirmed the plans, which were first reported by the Wall Street Journal.

The scientific finding has long been the central basis for U.S. action to regulate greenhouse gas emissions and fight climate change.
