President Joe Biden said the U.S. would aim to cut greenhouse-gas emissions roughly in half by 2030 during his opening remarks at the White House climate summit Thursday morning.

“That’s where we’re headed as a nation, and that’s what we can do if we take action to build an economy that’s not only more prosperous but healthier, fairer and cleaner for the entire planet,” Biden said.

“This is a moral imperative, an economic imperative,” he continued. “We have no choice, we have to get this done.”

The goal, which relies heavily on the green energy subsidies included in Biden’s infrastructure package, would see the U.S. cut emissions by as much as 52 percent below its 2005 levels within the next ten years.
