Democratic presidential hopeful Joe Biden is crafting a climate change policy he hopes will appeal to both environmentalists and the blue-collar voters who elected Donald Trump, according to two sources, carving out a middle ground approach that will likely face heavy resistance from green activists.

The backbone of the policy will likely include re-joining the United States with the Paris Climate Agreement and preserving U.S. regulations on emissions and vehicle fuel efficiency that Trump has sought to undo, according to one of the sources, Heather Zichal, who is part of a team advising Biden on climate change. She previously advised President Barack Obama.

The second source, a former energy department official also advising Biden’s campaign who asked not to be named, said the policy could also be supportive of nuclear energy and fossil fuel options like natural gas and carbon capture technology, which limit emissions from coal plants and other industrial facilities. [...]

The approach, which has not been previously reported, will set Biden apart from many of his Democratic rivals for the White House who have embraced much tougher climate agendas, like the Green New Deal calling for an end to U.S. fossil fuels use within ten years. That could make Biden a target of environmental groups and youth activists ahead of next year’s primary elections.
