Her “economic patriotism” agenda would pull on several levers of industrial policy, creating a Green Apollo Plan that would inject $400 billion into clean-energy research and development; a Green Industrial Mobilization Plan that would commit the government to spend $1.5 trillion on American-made emissions-free technologies; and a Green Marshall Plan that would provide $100 billion to help other nations buy those US products.

Between these and other plans, Warren wants to pour some $3 trillion of federal money into climate-related initiatives over the next 10 years, partially funded by reversing President Donald Trump’s earlier tax cuts.

She also says she would recommit the US to the Paris climate accords on day one of her presidency. The landmark international agreement strives to prevent the world from exceeding a dangerous 2 ˚C of warming, but the Trump administration is in the process of withdrawing the nation.

Her broader plan to overhaul trade would require all parties to US trade agreements to commit to independently verified plans for cutting emissions under the Paris agreement, and eliminate their domestic fossil-fuel subsidies. It would also implement a border carbon adjustment, or a tax on carbon-intensive imported products, to discourage US companies from simply setting up shop elsewhere to avoid tightened climate rules.

Here are Warren’s position on other key energy issues.

Electricity: Her policies would set a target of producing 100% of the nation’s electricity from “clean, renewable, and zero-emissions energy” by 2035.

Vehicles: Her plan would require all new passenger vehicles and buses to be emissions-free by 2030. She’s also proposed a “Clean Cars for Clunkers” program to more rapidly remove gas guzzlers from the road.

Carbon tax: Her campaign has said she is “open to” a price on carbon, either as a carbon tax or as a cap-and-trade program, according to the Washington Post.

Fracking: On her first day in office Warren would declare a moratorium on new fossil-fuel leases on public lands, halting extraction of oil and gas that produce nearly a quarter of the nation’s emissions, she said in her public lands plan. Her campaign also told the Washington Post that she would “ban all fracking,” shutting the tap on a source that fuels about a third of US energy consumption.

Nuclear: Warren came out strongly against nuclear power during the CNN climate change town hall. She said no new plants would be built under her administration and that we should “start weaning ourselves off nuclear and replace it with renewables.” In a December debate, she softened that stance, saying: “We have to stop putting more carbon in the air. That means we need to keep some of our nuclear in place.”

Feasibility and risks: It would require a major shift in political power and a massive legislative effort to secure the buy-in and funding necessary to pull off Warren's extremely ambitious plans.
