Among the Obama administration's major accomplishments during eight years in office was a sweeping series of environmental regulations governing everything from clean air and water to greenhouse gas emissions and auto fuel efficiency.

It looks like much of that work may be reversed in just a few days of the new Trump administration.

Donald Trump has broadly attacked a wide range of government regulations, echoing complaints of congressional Republicans and some business leaders that economic growth has suffered.

"We have been stuck in a terrible, over-regulated economy for eight years," former General Electric CEO Jack Welch told CNBC on Wednesday.

Welch and other critics of Obama administration regulations now have an opportunity to see many of them rolled back.

Trump has singled out Obama's Affordable Care Act and the landmark Dodd-Frank financial regulations as targets for repeal. But the list of rules subject to repeal includes a wide range of actions undertaken by the White House governing everything from food safety to internet network neutrality.

Republicans on Capitol Hill are already gearing up for the regulatory rollback.

"You're going to find that we are going to repeal a half dozen or more regulations in the first week of Congress," Kentucky GOP Sen. Rand Paul told MSNBC on Wednesday. "And I'm excited about it because I think the regulations have been killing our jobs and making us less competitive with the world."

A swift reversal of White House policies would not be unusual. President Barack Obama made similar moves in the early days of his administration after succeeding Republican president George W. Bush. Those moves included some of the environmental policies and regulations that are now targeted for repeal by Trump.
