US President Joe Biden unveiled an ambitious plan to combat climate change last week, setting a new national goal to reduce greenhouse gas emissions. According to him, the United States is aiming for a 61%-66% reduction in emissions by 2035, compared to 2005 levels. "We will turn this existential threat into a unique opportunity to reshape the future of our country," Joe Biden said, stressing that the new plan represents "the boldest climate program in the history of the United States." •
