With a final regulation published Saturday, Pennsylvania has become a leader in the fight to diminish dangerous atmospheric warming. It is now the largest power-producing state within the 12-state Regional Greenhouse Gas Initiative.
The RGGI is environmental policy rooted in fundamental economics. Historically, the United States has not attached a direct cost to pollution, so power generators have produced massive amounts of it. For the first time, RGGI will apply a direct cost to carbon air pollution. It also creates a market mechanism for generators to mitigate those costs while accelerating the transition from fossil fuels to carbon-free renewable fuels for power production, including nuclear, solar, wind and hydropower.
