Democratic presidential candidate Joe Biden expressed support for “complete zero emissions by 2025” by transitioning away from oil during the debate with President Donald Trump Thursday night.

“Because the oil industry pollutes significantly,” said Biden. “It has to be replaced by renewable energy over time.”

Biden mentioned solar and wind energy, but renewable fuels were not specifically mentioned by either candidate. Later in the segment on climate change, Biden stretched the deadline for zero emissions beyond 2025. “We have to move toward net zero emissions. The first place to do that by the year 2035 is in energy production, by 2050 totally.”

The former vice president also said he is does “rule out banning fracking,” but wants to make sure we can “capture the emissions from the fracking.”
