Trump Administration set to repeal US climate regulation

On Thursday, the administration of Donald Trump plans to announce "the repeal" of a scientific conclusion that greenhouse gas emissions endanger human sanity. This will remove the legal basis of federal climate regulations.

This is the biggest climate change policy rollback the administration has ever made. It follows a series of regulatory reductions and other actions designed to reduce the restrictions on fossil fuel development, and to stymie clean energy deployment.

Trump believes that climate change is a hoax and has pulled the United States out of the Paris Agreement. This leaves the United States, the largest contributor historically to global warming, outside the international efforts to fight it.

The United States adopted the so-called "endangerment" finding in 2009. This led the EPA, under the Clean Air Act of 1963, to take actions that would curb the emissions of methane and carbon dioxide from power plants, vehicles and other industries.

Officials told the Wall Street Journal that the repeal of the law would remove the requirement to measure, report and certify federal greenhouse gas emission standards. However, it may not apply initially to stationary sources like power plants.

I was not able to confirm these details.

According to EPA data, the transportation and power industries are responsible for about a quarter each of U.S. emissions.

Legal and regulatory uncertainty could be unleashed if the industry groups reverse the policy. Legal experts said that the policy reversal would, for example lead to an increase in "public nuisance" lawsuits. This path had been blocked by a Supreme Court ruling in 2011 that GHG regulation was best left in the hands of the Environmental Protection Agency.

Robert Percival is a professor of environmental law at the University of Maryland.

Environmental groups have called the repeal proposal a threat to the climate. The endangerment finding would likely need to be reinstated by future U.S. administrations if they want to regulate greenhouse gas emission. This could be a politically and legally difficult task.
