Waste Management Hailed as Climate Change Leader for Third Straight Year

Waste Management (NYSE: WM) has earned an A grade from environmental non-profit CDP for the depth and quality of climate change data it discloses to investors and the global marketplace.

CDP's 2018 Climate A List places Waste Management among a highly competitive group of companies from around the world identified as leaders in their efforts to combat climate change. While thousands of businesses disclose their environmental performance through the CDP, few gain the coveted A rating. The rating acknowledges the company's actions to cut emissions, mitigate climate risks and develop the low-carbon economy in the past CDP reporting year.

"We are honored to be recognized among this vanguard of companies taking strategic action to preserve our environment," said Jim Fish, president and chief executive officer of Waste Management. "Our commitment to annual disclosure of our carbon footprint is key to our work with employees and customers to reduce greenhouse gas emissions in ways that benefit both the environment and the economy."

Waste Management has been included in CDP's survey results since 2004, and this is the third year in a row that Waste Management has achieved a position on CDP's Climate A List. The Climate A List and full company scores are available on CDP's website: CDP 2018 Scores.
