In June 2013 President Obama announced he would use his executive power to take steps to combat climate change.
“I refuse to condemn your generation and future generations to a planet that’s beyond fixing,” he said in a speech at Georgetown University unveiling the plan.
The overall goal is a 30 percent reduction in emissions nationwide by the year 2030. States will be directed to craft plans to meet their own specific targets.
Pennsylvania– the nation’s third-largest emitter of carbon dioxide and fourth-largest coal producer–would be required to reduce its greenhouse gas emissions by about 32 percent over the next 15 years. The president’s most controversial move is directing the federal Environmental Protection Agency (EPA) to require cuts to greenhouse gas emissions from existing power plants. The agency has also proposed rules to limit emissions from all future power plants.
Obama is also promoting the expanded use of renewable energy. Pennsylvania is one of 35 states that already sets targets for renewable energy through its Alternative Energy Portfolio Standard (AEPS). Passed in 2004, the law requires the state’s utilities to purchase eight percent of their overall power from so-called “tier 1″ alternative sources– like wind and solar– by 2021.
The White House plan has been sharply criticized by the coal industry. The Pennsylvania Coal Alliance calls Obama’s plan “the biggest obstacle to continued coal use that has confronted the industry in decades” and says it’s a “de facto attempt to transform America’s energy usage away from coal.”
Coal currently supports over 8,000 direct mining jobs in Pennsylvania and supplies about 40 percent of the state’s electric power.
Governor Tom Corbett believes the scientific consensus around man-made climate change is still the subject of debate and views Obama’s climate initiative a “war on coal” and a “war on jobs.” Environmental groups have largely praised the president, with some arguing he’s not going far enough.
Aside from the new federal rules, the coal industry has also faced increasing competition from low-priced natural gas. Pennsylvania’s Marcellus Shale has rapidly become one of the most productive gas plays on the planet and power plants have been shifting from coal to natural gas. Obama has touted the role of natural gas in reducing carbon emissions.
Nationally, energy-related carbon emissions have reached their lowest level in 20 years, in part due to the surge in natural gas use, which produces less carbon pollution compared to coal. However scientists are still trying to determine the overall role of gas in climate change by tracking methane leaks and emissions. Methane is much more potent as a heat trapping greenhouse gas, compared to carbon dioxide. As part of the climate plan, the Obama administration has also announced efforts to cut methane emissions from natural gas systems.
Earlier this summer, the EPA held a series of public hearings on its proposed rules for existing power plants– including one in Pittsburgh. The agency plans to have final rules developed by June 2015.
