Award recognizes leadership in ethical business practices and commitment to sustainability

Waste Management has been recognized by the Ethisphere Institute as one of the 2013 World's Most Ethical Companies. Ethisphere is a leading international organization dedicated to the creation, advancement and sharing of best practices in business ethics, governance, anti-corruption and sustainability.

This is the sixth year WM has been honored for upholding the highest of ethical standards. The company was chosen for its strong corporate culture focused on deep commitments to environmental sustainability, ethics and communities and setting and achieving ambitious sustainability goals.

"This recognition from Ethisphere reflects our most fundamental commitment to keeping the environment - and our people and our neighbors - safe," said David Steiner, WM CEO and president. "As an industry leader, we continue to develop strategies to extract value from waste, which both minimizes our environmental impact and saves our customers money."

This is the seventh year Ethisphere has published the World's Most Ethical rankings. Ethisphere evaluated a record number of applications this year and reviewed nominations from companies in more than 100 countries and 36 industries. After conducting in-depth research and a multi-step analysis, Ethisphere named companies that surpassed their industry peers to this year's World's Most Ethical Companies list.

"This is one of our company's proudest achievements," said Lori Caso, WM spokesperson for upstate New York. Locally, Waste Management is the parent company of CWM Chemical Services, the hazardous waste landfill in the Town of Porter.

The methodology for the WME ranking includes reviewing codes of ethics, litigation and regulatory infraction histories; evaluating the investment in innovation and sustainable business practices; looking at activities designed to improve corporate citizenship; and studying nominations from senior executives, industry peers, suppliers and customers.

"Waste Management continues to be a staple component of our list, for the sixth year running, and we are pleased to reward its commitment to ethical business practices," said Alex Brigham, executive director of Ethisphere. "Waste Management has accomplished a great deal through its various sustainability initiatives, and we are excited to see the company continue to make major progress in achieving its goals."
