Green is good.

Many employers are getting more eco-conscious even as workers call for businesses to follow more sustainable practices. According to the “Recycling in the Workplace: A Millennial View” survey conducted by global research organization Lightspeed with Rubbermaid last year, nine in 10 millennials say it is important that they work for a sustainable company, compared to 84% of Gen Xers and 77% of Baby Boomers. And almost one in 10 millennials said they would quit if they learned that their current employer was not sustainable.

So ahead of Earth Day on April 22, Glassdoor ran through the job listings at eco-friendly companies listed on its company review site. Workers don’t have to feel guilty about earning their green with these nine employers.

Recreational Equipment, Inc. (a.k.a.
