President Biden has mapped out a $2 trillion clean energy and green jobs plan, pledging to set the U.S. on the path to net-zero greenhouse gas emissions by 2050 and to shift the nation away from fossil fuels. During his first weeks in office, Biden rejoined the Paris Climate Agreement and issued an executive order that directs agencies to make climate change a top domestic priority. In this online discussion, Todd Stern — the United States’ chief negotiator at the 2015 Paris Climate Agreement — will shed light on President Biden’s environmental agenda, discussing the challenges the Biden-Harris administration faces as well as the larger national context.
