Bennet on climate change

Mr. Bennet is in line with the rest of the Democratic field in calling for recommitting to the Paris Agreement and preserving Obama-era climate regulations that Mr. Trump is reversing. He has also supported regulating methane emissions and creating a standardized metric for the federal government to measure the cost of greenhouse gas emissions.

In March, he helped create the Senate Special Committee on the Climate Crisis, and last month, he was co-sponsor of a bipartisan bill that would provide tax incentives for energy storage.

In other areas, though, he has diverged from the party’s left wing. In a USA Today op-ed essay in 2017, he said some Democrats had played into Republicans’ portrait of them as “job killers fundamentally out of touch with most Americans.”

“It is not enough to call for less coal or oil without having meaningful work to replace lost jobs,” he wrote, and “when Democrats oppose natural gas, we fail to appreciate both its importance to small-town economies and its pivotal role in reducing coal production.”

He also suggested that instead of opposing the Keystone XL pipeline, Democrats should have negotiated a deal that approved the pipeline in exchange for emission reduction measures.
