CLAIM: Fracking is a “transitional fuel” at best, and contributes to the problem of climate change.

VERDICT: False. Fracking has helped the U.S. reduce emissions while growing its economy.

NBC News’ Chuck Todd asked candidates in the Democrat debate in Las Vegas, Nevada, whether they would eliminate fracking. He asked Sen. Bernie Sanders (I-VT), who wants to end it within five years, what he would tell workers in the energy industry who might lose their jobs. And he asked Sen. Amy Klobuchar (D-MN) if her slower approach was risky, given that scientists were “sounding the alarm.”

Both the moderator and the candidates accepted the premise that fracking makes climate change worse.

In fact, fracking — or “hydraulic fracturing,” in more technical terms — has helped the U.S. reduce its carbon emissions by allowing the energy industry to harness vast reserves of clean-burning natural gas.

Last year alone, U.S. emissions fell by 2 percent, in the midst of an economic boom where Americans were producing and consuming more, thanks to a switch from coal to natural gas, much of it made available through fracking. The shift to renewable energy is a minor factor compared to natural gas. The U.S. is virtually unique among all industrial economies in achieving this environmental, economic feat.

Fracking is only “transitional” if the ultimate goal — as even “moderate” billionaire Michael Bloomberg said — is to move to “all renewables.” But given that the goal of “all renewables” is still a fantasy, the fact remains that fracking is, provably, part of the solution to climate change, not part of the problem.
