Democratic presidential hopeful Bernie Sanders released a sweeping $16.3 trillion climate plan on Thursday, vowing to create 20 million jobs and completely zero out planet-heating emissions by 2050.

The proposal outlines easily the most ambitious vision for a Green New Deal to date, with calls to massively expand public ownership of everything from power generation to groceries. With Washington Gov. Jay Inslee ending his climate-centered bid for the Democratic nomination a day earlier, the plan vaults the Vermont senator ahead of his 2020 rivals on whats emerging as the defining policy issue of the Democratic primary.

At a moment when record wildfires are raging from the Amazon to the Arctic and Greenland is losing up to 12.5 billion tons of ice in a single day, the plan is dense with detail and frank in its goals. Where other proposals, including those from Inslee and Sen. Elizabeth Warren (D-Mass.) depict expanded regulatory regimes and public spending aimed at spurring private investment, Sanders charts out a path to a hospitable global climate through Nordic-style social democracy.

The scope of the challenge ahead of us shares some similarities with the crisis faced by President Franklin Delano Roosevelt in the 1940s, the plan states. Faced with battling a world war on two fronts both in the East and the West the United States came together, and within three short years restructured the entire economy in order to win the war and defeat fascism. As president, Bernie Sanders will boldly embrace the moral imperative of addressing the climate crisis.

The campaign declined a request to interview Sanders on Wednesday evening.

The plan opens with Sanders vowing to slash U.S. emissions 71% below 2017 levels by 2030 with 100% renewable electricity and zero-emissions vehicles. He declares war on the fossil fuel industry with proposed bans on fracking, drilling on public lands and all imports and exports of oil and gas, and threatens companies with civil and criminal charges for pollution and obstructing climate action. He pledges $200 billion to help developing countries reduce their own climate pollution by 36% in the next decade.

Citing the nuclear disasters in Chernobyl and Fukushima, Sanders, long a critic of nuclear power, swears off new reactors and promises a moratorium on future licenses to existing plants. His plan rules out geoengineering the climate or deploying technologies to capture carbon dioxide from fossil fuel plants, which he derided as false solutions. Its unclear whether hed consider carbon capture technologies for difficult-to-decarbonize industries like cement making.
