PA’s Switch from Coal to NatGas Netted at Least $500B in Benefits
The switch from coal to natural gas in power generation has led to historic emissions and air pollutant reductions equaling $450 billion to $1.04 trillion in public health benefits for Pennsylvanians, according to a Marcellus Shale Coalition (MSC) analysis. The analysis leverages emissions data from the Pennsylvania Dept. of Environmental Protection (DEP) and applies U.S. Environmental Protection Agency (EPA) methodologies to assign a dollar value to each ton of NOx and SOx reduced. As shale gas development became prevalent across PA and in-state natural gas electric generation increased from 5% to 59% between 2005-2022, criteria emissions contributing to respiratory ailments — nitrogen oxides (NOx) and sulfur oxides (SOx) — are down 81% and 93%, respectively, yielding a range of $7.9-$18.4 billion in NOx and $445.1 billion – $1.02 trillion in SOx cumulative public health benefits for Pennsylvanians.
