In an executive order, President Donald Trump rolled back a number of regulations that required reductions in greenhouse gas emissions. While its immediate impact will be limited, the move reduces the federal regulatory burden on industries—notably coal, oil, and gas mining.
The March 28 order directs federal agencies to no longer consider greenhouse emissions when permitting energy, infrastructure, and other projects and stops the agencies from factoring the “social cost of carbon” into their decisions.
The order also directs the Environmental Protection Agency and Interior Department to review rules that govern oil and natural gas developments.
