As a follow-up to President's Climate Plan, The White House has issued state climate reports.
The Pennsylvania White House climate report has several interesting facts. For example, Pennsylvania has had 13 storm disaster declarations in the last 10 years. It's carbon emission from power plants and industrial sources were 150 million tons in 2011 or less than 3% of US emissions.
Pennsylvania's power plant emissions fell significantly in 2012, as gas displaced considerable amounts of coal generation. As a result, the current number is certainly below the 150 million tons in this White House Climate Report 2011.
