Gov. Josh Shapiro’s administration said Nov. 21 that it is appealing a court ruling that blocked a state regulation to make Pennsylvania’s power plant owners pay for their planet-warming greenhouse gas emissions, even as the Democrat warned lawmakers to get to work on a better alternative.

In a statement, Shapiro didn’t pledge to enforce the regulation, should his administration win the appeal at the Democratic-majority state Supreme Court. His appeal revolves around the need to preserve executive authority, his administration said.
