New York Times: Yesterday Governor Chris Christie announced that New Jersey would become the first state to withdraw from the Regional Greenhouse Gas Initiative, a 10-state trading system, reports Mireya Navarro for the New York Times. Under RGGI, 10 Northeastern and mid-Atlantic states ranging from Maine to Maryland set a ceiling on carbon dioxide emissions and require power plants to purchase credits that allow them to emit specified amounts of carbon dioxide. According to Christie, the initiative “does nothing more than tax electricity, tax our citizens, tax our businesses, with no discernible or measurable impact upon our environment.” Environmental advocates called the decision a serious blow to the state’s efforts to reduce emissions from power plants and foster a shift from fossil fuels to renewable energy. Nevertheless, Christie says that New Jersey would continue to work to reduce its carbon dioxide emissions by increasing the proportion of electricity generated by natural gas, the Sun, and the wind.
