"Pennsylvania will no longer seek to be part of a regional climate agreement among states in the Northeast U.S.

A recent budget deal ends the commonwealth’s effort to participate in the Regional Greenhouse Gas Initiative (RGGI), according to a statement from state Senate Republicans.

The initiative sets a cap on planet-warming emissions and requires power plants in the states to purchase allowances to release carbon dioxide.

In 2019, then-Gov. Tom Wolf (D) issued an order seeking to join RGGI. That order was challenged in court and has been the subject of an ongoing legal fight."
