Mostly agree: The Democratic candidates favor taking steps to preserve the environment and taking action to alleviate the worst effects of climate change.
Most candidates back the "Green New Deal," a sweeping plan that would transition the American economy from fossil fuels to clean energy and curb greenhouse gas emissions.
And 18 of them have signed the No Fossil Fuel Money Pledge, promising to not seek financial support from the oil, coal and gas industries. Fifteen candidates also support having a climate change debate.
The divide: The devil is in the policy details.
Few of the people taking the primary stage have the ambition of Washington Gov. Jay Inslee, who has centered his campaign on fighting climate change and rolled out policy proposals to achieve 100 percent clean energy by 2030, a decade-long $9 trillion investment plan, and phasing out fossil fuels.
That hasn't stopped other Democrats from trying to match Inslee. Warren bills her "green manufacturing plan" as a $2 trillion investment in climate-friendly industries that would boost American manufacturing and promote job creation.
O'Rourke has also released a climate plan with an eventual $5 trillion price tag that sets a legally-binding target of net-zero greenhouse gas emissions by 2050.
Biden released a similar plan pegged to the 2050 deadline, calling for $1.7 trillion in federal spending, a carbon pollution tax, and job training for workers to readjust in a greener economy. Sens. Kamala Harris, Kirsten Gillibrand, Cory Booker, and Buttigieg have not issued climate proposals.
