We are committed to protecting the environment and are continuously working to reduce air emissions from our operations. Natural gas, widely considered the cleanest-burning fuel available for large-scale generation of electricity, is part of this commitment.
Increasing the use of natural gas in the energy mix is the fastest and most economical path to significantly reducing U.S. greenhouse gas (GHG) emissions, particularly carbon dioxide (CO2). Combustion of natural gas generates very little sulfur dioxide and nitrogen oxides, which helps curb the formation of acid rain and smog. Burning natural gas also has the added benefit of not generating soot or volatile organic compounds.
According to the U.S. Environmental Protection Agency1, natural gas used for power generation produces half as much carbon dioxide, less than a third as much nitrogen oxides, and 1% as much sulfur oxides at the power plant compared to the average air emissions from coal-fired generation.
In fact, a June 2011 study by the Massachusetts Institute of Technology Energy Initiative found the difference in GHG emissions to be so dramatic that it recommended replacing coal with natural gas as "the most practical near-term option for significantly reducing carbon dioxide emissions from power generation."2
