Recognized for Environmental, Social and Governance Performance

HOUSTON–(BUSINESS WIRE)–Waste Management (NYSE: WM) has been named to Corporate
Responsibility Magazine’s prestigious 100 Best Corporate Citizens
list for the fifth consecutive year.

The 20^th annual 100 Best Corporate Citizens list recognizes
standout environmental, social and governance (ESG) performance of
public companies across the United States.

“At Waste Management, we work every day to serve and support our
communities, stakeholders and world,” said Jim Fish, president and chief
executive officer of Waste Management. “This recognition reaffirms our
commitment to operate responsibly and respectfully – and to the highest
environmental, social and ethical standards. It also inspires us to
continue our quest for sustainable solutions, collaborative community
partnerships and a vibrant future.”

The 100 Best Corporate Citizens list documents 260 ESG data points of
disclosure and performance measures in seven categories: environment,
climate change, employee relations, human rights, governance, finance
and philanthropy and community support. The list ranks the Russell 1000
Index, a roster of the 1,000 largest U.S. public companies.

“U.S. corporate leadership matters more than ever to drive progress
despite government gridlock around environmental and social topics like
climate change. Transparency and public commitments make corporate
responsibility and sustainability programs stronger,” said Dave Armon,
CEO, 3BL Media.

“This commendation by CR Magazine is thanks to hard-working,
hard-driving men and women of Waste Management,” said Fish. “Our team is
dedicated to making a difference – on the job, in our neighborhoods and
