Information
An image showing the certification badges
Sustainability at Work certified organizations walk the talk of green business, from recycling and reducing energy to bike commuting and community giving. (Note: We are not currently certifying new businesses.)

Businesses are certified through 2023

The Sustainability at Work certification program stopped actively certifying businesses in 2020. Certification lasts three years, so the current directory reflects certifications valid through 2023.

Looking for green businesses? We encourage you to support the businesses on this page, as well as those certified through other programs.

Want to green your own business? We’ve converted our certification applications into DIY sustainable business guides.
