Cory Booker

U.S. senator, New Jersey

Booker supports banning fossil fuel exports, he told The Post. In his climate plan, Booker pledged to “reinstate the ban on crude oil exports; and expand the ban to cover all fossil fuel exports by 2030.”

Tulsi Gabbard

U.S. representative, Hawaii

“Yes, I support a federal ban on fossil fuel exports,” Gabbard told The Post.

Jay Inslee (Dropped out)

Governor, Washington state

Inslee is no longer running for president. “Yes. We must stop burning fossil fuels at home as well as sending that pollution around the globe,” Inslee told The Post. “It was a mistake for Congress to repeal the crude oil export ban, and I do not support the Trump Administration’s continued efforts to ship our fossil fuel pollution abroad — and increase domestic energy prices.”

Bernie Sanders

U.S. senator, Vermont

“Yes. When [Sanders] is in the White House, he will ban all fossil fuel exports,” a campaign spokesman told The Post.

Joe Sestak

Former U.S. representative, Pennsylvania

“Yes, though we should not ban all fossil fuel exports immediately, we must phase them out quickly while working to reduce the impact to American workers,” Sestak told The Post.

Elizabeth Warren

U.S. senator, Massachusetts

“I support re-imposing limits on crude oil exports and I opposed lifting the 40-year-old ban on exporting crude oil,” Warren told The Post. “The Puerto Rico and Virgin Islands Equitable Rebuild Act, of which I am a sponsor, specifically prohibits the use of funds to rebuild the islands’ electrical grids from being used to construct new liquefied natural gas import and export terminals.”

Marianne Williamson

Author

Williamson supports a ban on fossil fuel exports, she told The Post.

Steve Bullock

Governor, Montana

“No. I believe other policy measures can transition existing export industries and reflect the social costs of greenhouse gases from their production and export,” Bullock told The Post. “I believe the fossil fuel export industry must provide the leadership and investment to transition energy systems internationally to lower emissions solutions in the interim.”

John Delaney

Former U.S. representative, Maryland

Delaney does not support banning fossil fuel exports, he told The Post.

John Hickenlooper (Dropped out)

Former governor, Colorado

Hickenlooper is no longer running for president. “No,” Hickenlooper told The Post. “I support a dedicated effort to transition from fossil fuels to clean energy. My climate change plan includes a carbon tax, which will create the necessary market incentives to quickly and cost-effectively lower carbon emissions.”

Seth Moulton (Dropped out)

U.S. representative, Massachusetts

Moulton is no longer running for president. “No, I don’t support a ban, but we need to implement policies to ensure that fossil fuel exports fall over time,” Moulton told The Post. “Banning American exports will hurt American producers that not only employ many Americans but are more heavily regulated than their counterparts overseas. Restricting fossil fuel exports will only make it more difficult to meet our decarbonisation targets. However, it is of pivotal importance that we incorporate the price of carbon emissions into the cost of fossil fuels. We cannot export fossil fuels at a price lower than its ultimate cost to society.”

Tim Ryan

U.S. representative, Ohio

“No. Natural gas exports through LNG not only has enormous economic benefits for American companies and workers, but also play a pivotal geo-political role in our assistance to allies in Central Europe in reducing their dependence on Russia for energy resources,” Ryan told The Post.

Eric Swalwell (Dropped out)

U.S. representative, California

Swalwell is no longer running for president. “Our work should be to reduce global demand for fossil fuels,” Swalwell told The Post. “That's done through innovation and by working with markets and other countries, not by ceding control of those markets to other world powers with terrible human rights records and goals that clash with our own. Moving forward means not banning fossil fuel sales, but making fossil fuels obsolete.”

Andrew Yang

Tech entrepreneur

Yang would not ban fossil fuel exports, he told The Post. At a CNN climate town hall, he said, “I think we have to stop subsidizing the industry, but I don’t think that includes banning exports. Because if our fossil fuel industry, which is going to be around for some period of time, is competitive and cost competitive enough to export to another country, I wouldn’t stand in the way of that.”

Michael Bennet

U.S. senator, Colorado

Bennet did not provide an answer to this question.

Joe Biden

Former vice president

“I think we should [ban fossil fuel exports], in fact, depending on what it is they’re exporting for what they’re replacing,” Biden said at a CNN climate town hall. “Everything is incremental.” His climate plan said the United States can “export our clean-energy technology across the globe and create high-quality, middle-class jobs here at home.” The campaign did not directly answer this question.

Pete Buttigieg

Mayor, South Bend, Ind.

Buttigieg told The Post he supports “a transition to 100% clean energy production in the U.S. and around the world.”

Former mayor, San Antonio

Castro did not provide an answer to this question.

Bill de Blasio

Mayor, New York City

Kirsten Gillibrand (Dropped out)

U.S. senator, New York

Gillibrand is no longer running for president. Gillibrand did not provide an answer to this question.

Kamala D. Harris

U.S. senator, California

“We must begin intentionally and deliberately transitioning away from fossil fuels, shifting from being an exporter of fossil fuels to an exporter of clean energy technology,” Harris's climate plan said. Her campaign had not clarified her position by publication.

Amy Klobuchar

U.S. senator, Minnesota

Klobuchar did not provide an answer to this question.

Wayne Messam

Mayor, Miramar, Fla.

“I would set a phasing period until the nation could be credibly and fully fueled by renewable energy,” Messam told The Post.

Beto O'Rourke

Former U.S. representative, Texas

O'Rourke “would take executive action on day one to require any federal permitting decision to fully account for climate costs and community impacts,” a campaign spokesman told The Post. “We must ensure that the resources we consume — even as we work quickly to transition to renewable energy — are governed by the strictest environmental laws, safeguards, and standards.”

Tom Steyer

Billionaire activist

Steyer did not answer this question by publication.
