WM named among most ethical companies
in the world

Seventh consecutive year to make list

New York – During its annual conference on March 20, the Ethisphere Institute, an independent
center of research promoting best practices in corporate ethics and governance, announced that
Waste Management had once again been named to its annual listing of World’s Most Ethical Companies. 

This is the seventh time Waste Management has been honored with this award, which recognizes
organizations that continue to raise the bar on ethical leadership and corporate behavior. It is also just
one of two companies named in the Environmental Services category.

To be named as a World’s Most Ethical Company, scores are generated in five key categories: ethics
and compliance program, leadership and innovation, governance, corporate citizenship, and
culture of ethics.
