Running for the U.S. Senate, Pennsylvania’s lieutenant governor supported carbon caps when he was mayor of Braddock and a fracking moratorium during his unsuccessful 2016 Senate campaign. Now, Fetterman balances the “existential threat” of climate change with a need for “energy security.” 

Fetterman’s advocacy won him the endorsement from the union representing Edgar Thomson workers. But environmental groups say candidates can’t make promises to the climate movement while also supporting fracking jobs.
