Are Biden's climate change targets ambitious enough?

On April 22 ( Earth Day)vand 23, United States President Joe Biden invited 40 world leaders to a virtual Leaders Summit. The purpose of this summit was to encourage large economies to cooperatively tackle the climate crisis and set more ambitious targets to reduce their greenhouse gas emissions.

The Leaders Summit was convened not only to pressure other polluting economies to ramp up climate ambition but also to announce the US’ new Nationally Determined Contribution or NDC under the Paris Agreement.
