Marcellus Fracked Gas Leads to Record Low Emissions in PJM Grid

PJM is the largest electric grid operator in the U.S. It serves 65 million people in 13 states plus the District of Columbia (including PA, OH, and WV). PJM recently issued a press release to tout a radical reduction in emissions of all types. From 2005 to 2023, carbon dioxide (CO2) emission rates fell 43% across PJM’s footprint. Emission rates for nitrogen oxides (NOx) declined 90%, and the rates for sulfur dioxide (SO2) dropped 96%. It is, says PJM, a new all-time low for electric power emissions across the PJM region. Why the drastic drop? Because (says the Marcellus Shale Coalition), a number of coal-fired power plants have been replaced by natural gas-fired plants.
