The 2020 Democratic presidential primary is already shaping up to be the most climate-centered election in modern history.
Some candidates in the crowded field crafted multi-thousand-word proposals that provide clear paths forward. Others have done little more than promise to reenter the U.S. into the 2016 Paris climate agreement ― a pledge that one 2020 contender dismissed during a debate as “kindergarten.” A candidate who dropped out last month ran solely on a book-length stack of climate policies.
Even as Democratic Party leaders quash efforts to organize an official debate on the climate crisis, TV networks stepped in to hold climate forums with the Democratic candidates. The first, CNN’s marathon seven-hour affair, is scheduled to begin at 5 p.m. EDT Wednesday.
Ahead of the event, we put together a cheat sheet to help readers understand the policies each campaign has put forward. This is by no means a comprehensive accounting of the proposals, but it offers a quick way to compare the candidates.
We excluded low-polling candidates who so far have added little to the climate debate, such as former Rep. Joe Sestak of Pennsylvania and Miramar, Florida, Mayor Wayne Messam. We included scores from Data for Progress on candidates whose proposals the left-leaning think tank analyzed, as well as some answers candidates submitted in response to a recent survey by The Washington Post.
The list also includes Washington Gov. Jay Inslee, who until last month was the race’s climate candidate, for comparison.
On Stage

The former vice president took heat earlier this year after Reuters reported that his campaign was charting a “middle ground” approach to climate change. Biden responded with a hefty proposal, based on the Green New Deal, to decarbonize the economy by midcentury.
His plans for new research funding for more efficient nuclear reactors and plans for public electric vehicle charging stations excited some, while a shifting position on fossil fuels raised alarms.
Cost: $1.7 trillion over a decade, but Biden hopes private, state and local investments bring the figure to “more than $5 trillion”
Jobs promised: “More than 10 million”
Bans:
Fossil fuel drilling on public lands? Supports ban.
Fracking? Unclear.
Subsidies to fossil fuel companies? Supports ban.
What Stands Out: Biden, long a critic of nuclear power, opens the door to “small modular nuclear reactors at half the construction cost of today’s reactors.” The plan also includes “more than 500,000” public charging ports for electric vehicles by 2030.
What The Wonks Criticize: The campaign addresses fossil fuels in only vague terms. Biden, whose campaign includes a former natural gas executive, made clear that fossil fuels could still play a role when sparring on the debate stage with Inslee.

The New Jersey senator was among the first to throw his weight behind the Green New Deal last year and sign on to the resolution. His plan puts a unique focus on poor, minority communities that often suffer the worst pollution ― which could prove advantageous, as the lead contamination crisis in Newark, where Booker served as mayor from 2006 to 2013, “dredges up uncomfortable memories,” as ABC News put it, of past water scandals.
Cost: $3 trillion by 2030
Jobs promised: Unspecified “millions”
Bans:
Fossil fuel drilling on public lands? Supports ban.
Fracking? Supports ban.
Subsidies to fossil fuel companies? Supports ban.
What Stands Out: The plan calls for establishing a $50 billion-per-year U.S. Environmental Justice Fund “charged with coordinating the most ambitious-ever federal effort to advance environmental justice and invest in communities long left behind.” It also prioritizes protecting and restoring public lands.
What The Wonks Criticize: The plan lacks details, and risks being overshadowed by Newark’s lead contamination crisis.

The South Bend, Indiana, mayor said the climate crisis helped inspire his unlikely run for the White House, and credited his age ― he’s just 37 ― for giving him a unique appreciation of the threat. Yet he has taken a piecemeal approach to climate policy so far. He joined calls for establishing a national Climate Corps, backed a climate tax and dividend scheme and promised to “at least quadruple” federal research spending on renewable power and energy storage technology.
Cost: At least $2.5 trillion
Jobs promised: 3 million
Bans:
Fossil fuel drilling on public lands? Supports ban.
Fracking? Supports ban, but only on new fracking.
Subsidies to fossil fuel companies? Supports ban.
What Stands Out: The plan calls for “net-zero emissions for all new heavy-duty vehicles, buses, rail, ships, and aircrafts” by 2040. Including airplanes is a unique goal, given how far behind electric planes are compared to other forms of electrified vehicles.
What The Wonks Criticize: The plan promises a thriving “carbon removal” industry by 2040, and hints that it would include paying farmers to sequester carbon, but it lacks details and, as its worded, leaves open the possibility of carbon capture for continued fossil fuel use.

The former housing and urban development secretary stood out early on for his proposals to overhaul drinking water infrastructure and combat the sort of lead contamination that plagues poor, predominantly minority cities such as Newark and Flint, Michigan. His campaign’s focus on communities of color adds extra weight to his justice-centered proposals.
Cost: $10 trillion in public and private investment
Jobs Promised: 10 million
Bans:
Fossil fuel drilling on public lands? Supports ban.
Fracking? Unclear.
Subsidies to fossil fuel companies? Supports ban.
What Stands Out: Having positioned himself as arguably the most progressive candidate on immigration, Castro’s calls to create a new “climate refugee” status and establish a program to resettle migrants from low-lying islands carries extra weight.
What The Wonks Criticize: The plan’s “Economic Guarantee for Fossil Fuel Workers” offers few details despite being pivotal to winning support for the policy. It also makes no mention of nuclear power.

Kamala Harris

The California senator was among the last to release a climate plan, with her latest out early Wednesday morning ahead of CNN’s climate forum. Harris leans heavily on existing legislation, including the Climate Equity Act she co-sponsored with Rep. Alexandria Ocasio-Cortez (D-N.Y.), as well as Oregon Sen. Jeff Merkley’s bill to transition to zero-emissions vehicles.
Cost: $10 trillion in unspecified “public and private spending over the next 10 years”
Jobs Promised: “Millions”
Bans:
Fossil fuel drilling on public lands? Supports ban.
Fracking? Unclear.
Subsidies to fossil fuel companies? Supports ban.
What Stands Out: Harris’ proposal prominently features a promise to designate 30% of U.S. land and ocean for conservation.
What The Wonks Criticize: The plan breaks little new ground. It also touts Harris’ record of “holding polluters accountable” as California’s attorney general, but under her leadership, the Golden State’s top law enforcement office failed to join high-profile investigations in New York and Massachusetts into oil giants’ efforts to obscure the realities of climate change.

The Minnesota senator’s approach to climate change focuses on reversing the Trump administration’s deregulatory agenda and putting the United States back on the course set under former President Barack Obama. Klobuchar also endorsed the Green New Deal resolution and vowed to introduce “sweeping” emissions legislation within her first 100 days in office.
Cost: $2 trillion, with another $1 trillion in bonds
Jobs promised: Unspecified
Bans:
Fossil fuel drilling on public lands? Supports ban.
Fracking? Does not support ban.

During the former Texas congressman’s bid to unseat Sen. Ted Cruz (R-Texas) last year, he bolstered his state’s oil and gas industry. He touted his record of voting to lift the export ban on oil and gas. After a kerfuffle with activists in which O’Rourke signed the No Fossil Fuel Money pledge, violated it, then renewed his commitment, his campaign became the first to release a comprehensive climate plan. The proposal, which helped set the tone for other campaigns, lays out a plan to make the United States carbon neutral by mid-century.
Cost: $1.5 trillion over a decade, but O’Rourke hopes to spur “at least $4 trillion” in related spending
Jobs promised: Unspecified
Bans:
Fossil fuel drilling on public lands? Supports ban.
Fracking? Supports ban, but only on new fracking.
Subsidies to fossil fuel companies? Supports ban.
What Stands Out: The plan calls for establishing the “first-ever, net-zero emissions by 2030 carbon budget for federal lands” and requiring all federal permitting decisions “to fully account for climate costs and community impacts.”
What The Wonks Criticize: The plan’s vagueness. Inslee, who put tackling the climate crisis at the center of his 2020 bid before dropping out of the race last month, called the plan “empty rhetoric” and said O’Rourke “will need to answer why he did not lead on climate change in Congress.”

The Vermont senator’s proposal is the most ambitious in scope and spending. The plan is also unique in how it finances its budget, in its proposals to redistribute wealth and in its ideas to right the original New Deal’s racist, sexist legacy.
Cost: $16.3 trillion over the next decade
Jobs promised: 20 million
Bans:
Fossil fuel drilling on public lands? Supports ban.

What Stands Out: Sanders would use military cuts and tax hikes on the wealthy to pay for the plan. The plan also includes a blueprint to nationalize electricity production and expand public- and worker-owned grocery stores and food processing plants.
What The Wonks Criticize: Sanders’ firm stance against nuclear power and carbon capture technology jeopardizes a focus on emissions cuts.

The Warren campaign’s motto is “I have a plan for that.” On climate, the Massachusetts senator has several. Warren has plans to eliminate drilling on public lands, decarbonize much of the U.S. military by 2030, put America’s public lands to use in the fight against climate change, require companies to disclose climate risk, use trade policy to lower emissions, and start a green manufacturing boom. On Tuesday, she released an overarching proposal that also adopts key energy components from former climate candidate Jay Inslee’s library of policies.

What Stands Out: The Warren campaign’s plans are rooted in the senator’s long-held belief that eliminating the corruptive political influence of fossil fuel companies is the key to comprehensive reform.
What The Wonks Criticize: Some on the left say Warren’s calls for “economic patriotism” and restrictive intellectual property rules on clean energy technology risk slowing global decarbonization and unfairly profiting off countries that are hardest-hit by the climate crisis.

Who Won’t Be On The CNN Stage:

The Colorado senator veers away from the Green New Deal in favor of a more centrist approach that will “endure across American elections and administrations.” His proposal puts a focus on rural communities and offers policy rebrands that could make federal programs more palatable to conservative voters.

What Stands Out: Bennet’s plan promises to reduce food waste 75% by 2030, targeting a significant but under-discussed source of emissions and waste. It rebrands popular public funding programs for climate proposals as Climate X Options.
What The Wonks Criticize: The plan calls for a Next Generation Climate Board of Directors “comprised of youth leaders to ensure that their energy and ideas are part of the solution,” though it’s unclear how such a panel would work. It also outlines a vision for states to compete for green infrastructure funding, which adds an extra barrier to making long-overdue upgrades.

Bill de Blasio

New York City’s mayor kicked off his long shot presidential bid with a press conference touting the Big Apple’s version of a Green New Deal. But while the nation’s biggest city has made strides on cutting emissions and requiring building owners to become more efficient, the achievement de Blasio is most fond of promoting ― divesting the city’s pension funds from fossil fuels ― has yet to actually happen.
