Joe Biden promised to reverse the Trump administration’s deregulatory effort and set the United States on course to hit net-zero emissions by 2050 under a plan the former vice president put forward Tuesday as a version of the Green New Deal initiative animating many of his 2020 rivals’ campaigns.

In a 10,400-word campaign policy proposal, the presumptive front-runner for the next Democratic presidential nomination laid out plans to ramp up renewable energy and electric car investments, spurring 10 million jobs over a decade, and ending fossil fuel subsidies.

“As president, I will lead America, and the world, not only to confront the crisis in front of us but to seize the opportunity it presents,” Biden said in a campaign video. “I’ll use every authority available to me to drive progress. And I will not accept half measures.”

But the plan, teased ahead of its release as what Reuters called a “middle ground” between big business and the Green New Deal movement, offers scant details and potentially leaves room for fossil fuels. And it operates on a timeline some advocates are likely to reject as too slow to avert catastrophic warming.

The Biden plan revives the Obama-era blend of regulation and multilateral agreements, taking an all-of-the-above approach that opens the door to nuclear power and advocating wide-scale deployment of carbon-capture technology. But it goes much further with the kind of spending rarely attempted in the deficit-obsessed eight years Biden served as vice president.

The plan calls for spending $1.7 trillion over a decade, meant to spur a total of $5 trillion of investment. It includes $400 billion on increased clean energy research and the construction of 500,000 new electric car charging stations by 2030. The proposal requires new buildings to slash emissions 50% by 2035. It flexes considerable foreign policy muscle, highlighting levers that a Biden administration could pull at trade and international agencies to pressure other countries to cut emissions.

Biden cites the Green New Deal as a “crucial framework” and nods throughout the proposal to the potential for emissions cuts to bring jobs. But the former vice president’s plan stops short of calling for the sort of full energy transformations on which his rivals are running.
