Where 2020 hopefuls stand on climate change policies

The first 2020 Democratic presidential debates spent 15 minutes on climate change. That’s more than the candidates spoke about the issue during presidential debates for the 2016 election, but it’s much less than would satisfy some who care about the issue.

Jay Inslee, the governor of Washington state, has structured his presidential campaign with climate change as its central focus.

“This is a climate crisis, an emergency,” Inslee said at the first Democratic primary debate on June 26, 2019.

Both advocates and candidates have called for a debate centered around climate change. The Democratic National Committee has rejected that approach, opting instead for 12 sanctioned debates focused on a range of issues.

Nonetheless, many candidates have plans, some lengthy and detailed, some brief and vague, to address climate change. Generally, the candidates support recommitting to the Paris climate agreement and implementing a Green New Deal, at least in some form. But there are some exceptions.

Former Colorado Gov. John Hickenlooper, for example, thinks the current Green New Deal, which includes guaranteeing a job to all Americans, would cause “needless tax increases” and “expansion of the federal government.”

That isn’t the only point of disagreement among candidates. The Democrats’ climate change proposals splinter in terms of how they plan to cut emissions, specifically whether or not they support implementing a tax on carbon.

As of this writing, candidates without specific or detailed climate change plans include Montana Gov. Steve Bullock, New York Mayor Bill de Blasio, and former U.S. Housing and Urban Development Department Secretary Julián Castro.

We’ll take you through some of the key points of the climate change discussion among the Democratic field. To see where the individual candidates stand on climate change policies, check out our chart.

Basics of climate change

Climate change is an expansive issue, encompassing increased temperature trends, sea level rise, ice mass loss, changes in plant blooming and extreme weather events. Global warming refers to the longterm warming of the Earth.

Burning fossil fuels, like coal, oil and natural gas, has been the main source of greenhouse gas emissions into Earth’s atmosphere. Without humans contributing these emissions, greenhouse gases, through the greenhouse effect, keep Earth’s surface warm. But the addition of emissions caused by human activities has led to a rise in global temperatures.

Carbon dioxide is the primary greenhouse gas emitted through human activities. U.S. greenhouse gas emissions originate mainly from transportation, electricity and industry.

“We can’t make climate change go away anytime soon, because the greenhouse gases we’ve already put into the atmosphere have not yet exerted their full impact on the climate system,” said Jennifer Francis, a senior scientist at Woods Hole Research Center.

Paris Agreement and foreign policy

Countries all over the world took a dramatic step to address climate change in December 2015 with the United Nations Paris Agreement. The agreement is an attempt by most countries to limit a global temperature increase during this century to 1.5 degrees Celsius above pre-industrial levels.

Under the agreement, developed countries pledged to take the lead in reducing emissions and to support developing countries in similar actions. The United States is one of the top emitters of carbon dioxide from fossil fuel combustion, according to the International Energy Agency.

Former President Barack Obama championed the Paris Agreement. But President Donald Trump pledged to cancel it and announced his plans to pull the United States out of the agreement in 2017, claiming that it was unfair to U.S. workers. (In the past, Trump has denied that global warming is real.)

Some Democratic candidates have said they will make the goals of the Paris climate agreement more ambitious.

Former Vice President Joe Biden’s climate plan states that he’ll ramp up the targets of the agreement, make the commitments more transparent and enforceable, and, more broadly, integrate climate change into his foreign policy strategy. That includes conditioning trade agreements on partners meeting targets for cutting emissions.

Plans from Inslee and Hickenlooper also say they will incorporate climate change goals into U.S. trade agreements.

Massachusetts Sen. Elizabeth Warren proposed a plan to address climate change in her approach to national security. She wants the Pentagon to achieve netzero carbon emissions for its non-combat bases and infrastructure by 2030.

Green New Deal

Seven of 10 Democratic presidential candidates who are members of Congress co-signed the Green New Deal, a resolution that addresses climate change, pollution, and income and racial inequality. The Democratic measure was introduced by Rep. Alexandria Ocasio-Cortez, of New York, and Sen. Ed Markley, of Massachusetts, in February 2019.

The resolution cites the 2018 National Climate Assessment, produced by over 300 federal and non-federal experts, which says climate change has worsened and increased a variety of events across the United States, including wildfires in the Northwest, droughts in the Southwest, flooding in the Southeast, snow storms in the Northeast and heavy rains in the Midwest. Earth’s climate is changing faster than at any point in the history of modern civilization, it found.

The Green New Deal focuses on goals to combat climate change, rather than specific paths. It calls for a transition to a net-zero greenhouse gas emissions economy and an energy sector powered entirely by zero-emission sources.

The Democratic presidential candidates who cosponsored the deal are Warren, New Jersey Sen. Cory Booker, New York Sen. Kirsten Gillibrand, California Sen. Kamala Harris, Minnesota Sen. Amy Klobuchar, Massachusetts Rep. Seth Moulton, and Vermont Sen. Bernie Sanders.

Inslee, a current governor, wants to put the deal into action through investing in clean energy and expanding jobs in the solar and wind sectors. His clean energy plan claims that, by 2030, the country will reach zero emissions in new lightand medium-duty vehicles, zero-carbon pollution from new commercial and residential buildings, and a requirement for 100% carbonneutral power.

Warren wants to invest $2 trillion over 10 years in “green research, manufacturing, and exporting,” with the goal to create jobs. She’s also proposed a ban on all new fossil fuel leases, including drilling offshore and on public lands.

Multiple candidates incorporated economic and racial justice into their climate change proposals through protecting public lands, addressing environmental and health threats, and creating jobs.

In October 2017, Booker introduced an environmental justice act in the Senate to, in part, require federal agencies to implement strategies that identify and address the human health or environmental effects of their programs and policies with respect to communities of color, indigenous communities and low-income communities. Gillibrand, Harris, Sanders and Warren co-sponsored the bill, which was never passed.

Alvaro Palacios Casanova, a senior policy advocate at the Center on Race, Poverty and the Environment, told PolitiFact that coming up with solutions to benefit environmental and social justice causes is difficult due to the fossil fuel industry’s political influence.

As of July 24, 2019, 21 Democratic presidential candidates signed a pledge to not take any contributions over $200 from oil, gas and coal industry executives, lobbyists and political action committees. Bullock, Hickenlooper and former Maryland Rep. John Delaney haven’t signed the pledge.

Carbon pricing

Various Democrats have incorporated putting a price on greenhouse gas emissions, typically through a tax, into their climate change plans. They include Biden, Delaney, Gillibrand, Hickenlooper, Inslee, South Bend, Ind. Mayor Pete Buttigieg, former Pennsylvania Rep. Joe Sestak, author and activist Marianne Williamson, and entrepreneur Andrew Yang.

In a January 2019 opinion piece, a bipartisan group of economists said that a carbon tax is the most costeffective method to reduce emissions “at the scale and speed that is necessary.”

But carbon taxes are not without controversy. Ten states have active carbon pricing programs, according to the Center for Climate and Energy Solutions, but voters have rejected carbon pricing initiatives in other states like Washington, where Inslee endorsed the program.

Some critics are concerned on the impact carbon pricing systems may have on low-income households; protests erupted in France after fuel tax hikes were put in place, and France later suspended the increases.

Tamra Gilbertson, a carbon pricing policy researcher at the Indigenous Environmental Network, is critical of a carbon tax and other carbon pricing systems because, if implemented, companies will continue to extract fossil fuels, she told PolitiFact. It’s better if the fuel stays in the ground.

But many countries have carbon pricing systems in place, including Canada and Mexico.

Kevin Trenberth, a senior scientist at the National Center for Atmospheric Research, told PolitiFact that climate change mitigation efforts need to be broadbased.

“A city by itself, or a state by itself or a small country like New Zealand can’t solve the problem or even necessarily do a carbon tax responsibly, unless everybody does it,” Trenberth said. WHATEVER YOUR HEARING NEEDS MAY BE, WE INVITE YOU TO OUR AND YOU’LL RECEIVE:
