Mike Bloomberg would shut down the nation’s remaining 251 polluting coal power plants and halt construction of 150 new gas facilities as part of a sweeping program to slash carbon emissions and boost clean energy alternatives if elected president.

Bloomberg’s plan — unveiled Friday during a campaign stop in northern Virginia — aims to cut US carbon emissions in half over 10 years and put the country on course to get 80 percent of its electricity generated from green energy sources, like wind and solar, by 2028.

The proposal would end taxpayer subsidies for fossil fuels and offer incentives for clean energy. Additionally, it would impose more stringent carbon and pollution standards for new gas plants, effectively barring new construction.

Bloomberg’s plan largely aligns with programs laid out by other Democrats — and stands in sharp contrast to President Trump’s public boosting of coal and oil.

The US became the top oil and natural gas producer in the world in 2018. Natural gas has replaced coal as the top energy source.

Combating climate change has long been one of Bloomberg’s pet causes.

The former three-term New York City mayor and billionaire philanthropist helped launch the Sierra Club’s Beyond Coal campaign, which led to the shuttering of more than half the nation’s coal plants.

He also this year started the group Beyond Carbon to tackle global warming.

“The president refuses to lead on climate change, so the rest of us must. I’ve been all in on this fight for more than a decade — and having helped close more than half the nation’s dirty coal plants, having cut New York City’s carbon footprint by 14 percent, having led a coalition of cities, states, and businesses committed to the Paris Agreement, I know that we can win,” Bloomberg said.

“We’ve proven that you can transition to clean energy and strengthen the economy at the same time. As president, I’ll accelerate our transition to a 100% clean energy economy.”

The former mayor promised details laying out how oil and coal workers could transition to new work, but provided no specifics Friday.

Bloomberg joined former California Gov. Jerry Brown and a coalition of mayors and governors pledging to abide by the Paris climate deal after Trump withdrew the US from it.
