Real estate mogul Donald Trump has won the presidential election, and that likely means the Obama administration’s global warming agenda will be massively scaled back or scrapped altogether.

Trump, a Republican, has promised to cut the EPA, scrap the Paris climate treaty and rollback rules holding back U.S. energy production.

“Just look at what Trump has promised,” a source close to Trump’s transition team told The Daily Caller News Foundation.

“Withdraw from Paris Climate Treaty, defund UNFCC, scrap EPA’s Daily Caller  New Foundationgreenhouse gas emissions rules, scrap the ‘waters of the U.S.’ rule, scrap Stream Protection rule and remove obstacles to oil, gas, and coal production,” the source said.

Trump has promised to rollback much of President Barack Obama’s global warming agenda, including the Environmental Protection Agency’s (EPA) global warming rule for power plants. Pro-energy and global warming skeptics were thrilled at Trump’s win.

“Climate sanity has been restored to the U.S.,” Marc Morano, the published of the global warming skeptic website Climate Depot, said in a statement.

“No longer do we have to hear otherwise intelligent people in charge in D.C. blather on about how UN treaties or EPA regulations will control the Earth’s temperature or storminess,” he said.

Trump’s win comes as United Nations delegates meet in Morocco to discuss how to implement a major global warming agreement hashed out in Paris last year. Trump promised to tear up the agreement, and scrap the main way Obama planned on meeting his climate pledge.

Some 27 states and dozens of businesses and union groups challenged the so-called Clean Power Plan (CPP) in court. Legal experts expected the rule to be upheld by the D.C. federal circuit court, but a Trump win makes a legal victory for EPA less important.

The CPP was the main regulation Obama was relying on to meet a pledge he made to UN members to get the Paris agreement passed. Obama pledged to cut U.S. greenhouse gas emissions 26 to 28 percent by 2025. That’s not likely without the CPP.

“The time for a Clexit has arrived, a U.S. exit from the UN Paris climate agreement,” Morano said.

Trump made the so-called “war on coal” a major part of his campaign message, traveling across coal states attacking EPA regulations for hurting miners. Trump handily won in coal states like, Kentucky, West Virginia and Wyoming.

Trump ‘s victories in Ohio and Pennsylvania, key swing states, were in no small part due to huge turnout in coal mining regions of the state. Trump’s stance on trade and energy likely resonated with voters there.

“We anticipate good policies moving forward such as the Keystone XL and Dakota Access pipelines, liquefied natural gas exports, and energy projects on non-park, non-wilderness federal lands,” Tim Wigley, president of the petroleum industry-backed Western Energy Alliance, said in a statement.

UN delegates who’ve worked for years to craft a global climate treaty were “stunned” at Trump’s victory. Some foreign officials said Trump would not be able to undo the Paris agreement.

“As I speak, 103 countries representing 70 percent of (greenhouse gas) emissions have ratified it, and he cannot — contrary to his assertions — undo the Paris Agreement,” Segolene Royal, France’s environment minister told French media.

Environmentalists were similarly convinced Trump would not be able to undo the Paris deal.

“Science cannot expect any positive climate action from him,” Hans Joachim Schellnhuber, head of the Potsdam Institute for Climate Impact Research, said in a statement.

“The world has now to move forward without the U.S. on the road towards climate-risk mitigation and clean-technology innovation,” he said.
