By now, we’ve all heard of freshman US Rep. Alexandria Ocasio-Cortez’s (D-NY) proposal to form a Select Committee For A Green New Deal, which is designed to create legislation that will shift the US economy to 100 percent renewables within ten years of passage. It has the support of dozens of other legislators, but it’s hardly the only proposal in the works. Fellow freshman Rep. Sean Casten (D-IL) thinks such high ambition could prove counterproductive, and Senator Ed Markey, who co-sponsored the Waxman-Markey cap-and-trade Bill back in 2009, is reportedly working on his own proposal.

At the same time, the number of viable candidates throwing their hats into the presidential race is growing, and while all of them advocate action on climate change, few have explicitly said how they will deliver – let alone whether they advocate a price on carbon.

In this scorecard, we will be tracking the candidates’ positions on climate and adjusting them as the positions come into focus. We are also reaching out to the candidates directly with specific questions, and we invite feedback from you on the issues we’ve chosen to highlight.

We want to hear from you, so feel free to contact me at szwick@forest-trends.org or utilize our comments section below. We consider this a living document that will expand, contract, and hopefully sharpen over time. We may change the title as themes emerge, and we may expand beyond the Democratic Party, too. For this list, we focused on declared candidates who have already held public office, and added in Andrew Yang because he seems to drawing attention.

Elizabeth Warren

General: Warren has proposed, but not yet introduced, legislation called the Climate Risk Disclosure Act, which would require public companies to quantify and disclose their climate risk exposure. Her proposal builds on the work of Michael Bloomberg’s Task Force on Climate-Related Financial Disclosures, which is a global task force designed to promote climate risk disclosure.

Price on Carbon: No public comments yet.

John Delaney

General: Delaney co-sponsored last year’s Energy Innovation and Carbon Dividend Act (HR 7173), along with three other Democrats and three Republicans. The returning sponsors say they will re-introduce it in the new session. The bill, in its current form, calls for a $15-per-ton carbon tax, increasing $10 every year, until it reaches $100-per-ton, with much of the proceeds going to low- and middle-income families hit hardest by rising energy costs. The goal is a 40-percent reduction in greenhouse-gas emissions within 12 years of passage, and a 90-percent reduction by 2050.

Green New Deal: Supports

Price on Carbon: He supports a carbon tax, which makes sense given his sponsorship of HR 7173
