President Biden is enjoying a honeymoon with many environmental advocates after coming under criticism during the 2020 Democratic presidential primary from green activist groups pressing him to be more ambitious on climate change.

Biden gained favor from a number of groups after winning the Democratic nomination by shifting to the left on climate change and working with progressives, some with ties to Sen. Bernie Sanders (I-Vt.), as part of a unity effort.

Since taking office, Biden has revoked a key permit for the Keystone XL pipeline, rejoined the Paris climate agreement and issued a temporary pause on new oil and gas leases for federal lands.

The moves come with some risks for Biden even as they have drawn applause from climate groups.
