This year, Exelon moved up 26 positions in the U.S. and jumped up 48 positions to 24 th in the global rankings as part of Newsweek Magazine's annual assessment of sustainability practices at the top 500 global publicly traded companies.

"We have a longstanding commitment to operating our business in an environmentally responsible way, and we recognize that providing clean energy is important to our customers," said Chris Gould, senior vice president and chief sustainability officer for Exelon. "This recognition by Newsweek validates our approach and leadership in sustainability, and we'll continue to make great progress in the years ahead."

Newsweek's Green Rankings evaluate the world's largest companies by market capitalization and rate them based on a variety of corporate sustainability and environmental impact factors, such as energy, greenhouse gas emissions, water and waste productivity; company reputation and board-level oversight. They are the result of comprehensive analysis by Newsweek, Corporate Knights Capital and an advisory board of representatives of nongovernmental, academic and accounting organizations.

The U.S. report consists of 500 of the largest publicly traded companies headquartered in the U.S. by revenue, and the Global 500 is an assessment of sustainability performance of the 500 largest publicly traded companies in the world as of Dec. 31, 2016.

Exelon, the nation's largest producer of emissions-free energy, has a recognized track record of leadership in environmental performance, sustainability and reducing greenhouse gas emissions. The company continues to lead, by providing its customers with tools and resources to reduce their carbon footprint, a strategy that saved enough electricity last year to power more than 1.5 million homes for one year.

Earlier this year, Exelon was also named to the Dow Jones Sustainability North America Index for the 12 th consecutive year and five of Exelon's utilities were named to EPA's Energy STAR Partner of the Year in 2016 for leadership in energy efficiency programs. In December of this year, the Chicago Area Clean Cities Coalition announced that ComEd was one of its Green Fleet Leadership Award winners for 2017, recognizing companies and government agencies leading in the adoption of alternative fuels and clean-vehicle technologies for their fleets.
