Benchmarking Air Emissions of the 100 Largest Electric Power Producers in the United States 2014

This report examines and compares the stack air pollutant emissions of the 100 largest power producers in the United States based on their 2012 generation, plant ownership, and emissions data and shows a downward trend in nitrogen oxides (NOx), sulfur dioxides (SO₂), mercury and carbon dioxide (CO₂) since 2000, with CO₂ emissions decreasing 13 percent between 2008 and 2012. The findings show that the industry is already shifting toward a combination of increased energy efficiency and lower carbon fuel sources.
