President Joe Biden on Thursday doubled US ambitions on slashing greenhouse gas emissions.
Putting the United States back at the forefront on climate, Biden told a virtual Earth Day summit that the world’s largest economy will cut emissions blamed for climate change by 50 to 52 percent by 2030 compared with 2005 levels.
“The cost of inaction keeps mounting. The United States isn’t waiting,” Biden told a two-day summit of 40 leaders including the presidents of rivals China and Russia.
“We have to step up,” Biden said. “We have to take action — all of us.”
Biden’s early and aggressive environmental push marks a drastic shift from his predecessor Donald Trump — but quickly raised questions on whether the United States can keep promises if another climate-skeptic president is elected in the future.
