A member of the PA Senate, Sen. Wayne Langerholc (R), and a member of the PA House, Rep. Jim Rigby (R), together penned a response to an inaccurate column written by PA Rep. Greg Vitali (D) concerning the Regional Greenhouse Gas Initiative (RGGI). In their response, Langerholc/Rigby flatly state, “Pennsylvania’s participation in RGGI is not about climate change or any other reduction in pollution.” So what is RGGI really about?
