Where Do the Presidential Candidates Stand on Climate Issues?

Sen. Bernie Sanders topped the Center's list as the only candidate to score a perfect 10 out of 10. He is a lead supporter and champion of the Green New Deal, and his website makes his plans for fighting the climate crisis clear.

Sen. Elizabeth Warren earned the second-highest score, with an 8 out of 10. Her website features a detailed page about "tackling the climate crisis head on," she calls addressing climate change a "top priority," and she is also a sponsor of the Green New Deal.

Kassie Siegel, the Center for Biological Diversity Action Fund's climate director, said in a statement that based on the scorecard, both Sanders and Warren “would use the full power of the presidency and commit trillions to fight this greatest threat to our planet,” as reported by The Hill.

If we're talking school grades, the four remaining candidates would have failed this test. 

Mayor Pete Buttigieg scored a 4 out of 10. On his website, he calls the climate crisis a catastrophe, he has expressed the urgency in which we need to enact climate policies, and he has a lengthy plan to address the climate crisis.

Vice President Joe Biden scored a 2 out of 10. He is a supporter of the Green New Deal, has a detailed climate plan on his website, and spoke passionately at this week's debate— but he just hasn't made enough promises to get him a higher score on the Center's scorecard.

Even though Mayor Michael Bloomberg has talked some big talk about his plans to move the U.S. towards clean energy, he scored just 1 out of 10.

Sen. Amy Klobuchar tied for last, with a score of 1 out of 10. Both Bloomberg and Klobuchar's sole checkmark was thanks to them stating they would end new fossil fuel leasing — which is actually the only category for which all six candidates received a checkmark.

Both Bloomberg and Klobuchar have shared their support of using natural gas a "transition fuel" away from oil and gas. But why not just skip ahead to renewable energy sources? As Earther put it, the two candidates' climate policies are "simply not enough."

“The stark differences between how the candidates would address the climate crisis shouldn’t be glossed over,” Siegel added, via The Hill. “Bloomberg’s climate plan contains almost no bold executive actions, firm targets to curb greenhouse pollution, or spending to confront the emergency.”

There are still two more Democratic candidates in the race, but they are both polling at 1 percent or less, and neither of them qualified for the debate this week or for the Center's climate scorecard: Tom Steyer and Rep. Tulsi Gabbard.

According to The New York Times, addressing the climate crisis is one of Steyer's signature issues. On the climate justice page of his website, he boasts: "On day one of my presidency, I will declare the climate crisis a national emergency." He plans to neutralize pollution by prioritizing transitioning workers to jobs in clean energy, establishing climate-friendly transportation, and supporting the low-income communities who are most affected by pollution.

On Rep. Tulsi Gabbard's website, she states support of a fracking ban, an intention to end fossil fuel and agribusiness subsidies, and plans to build a 100 percent renewable energy economy.
