The finalists include Cafe Yumm, Essex Construction, and Thermo Fisher Scientific.
The city says Cafe Yumm is a finalist because all of its restaurants are built to LEED standards, and one location has a solar-powered electric vehicle charging station.
Essex Construction made the list because employees are encouraged to become LEED certified, and the company donates electronics to NextStep Recycling and works with a number of environmental nonprofits.
And at Thermo Fisher Scientific, employees are encouraged to volunteer and give back to the community. The company also keeps 95 percent of its waste out of the landfill.
“It’s an award that it represents the triple bottom line of sustainability which is people, planet, and prosperity,” said Stephanie Scafa, Waste Prevention Analyst.
Mayor Kitty Piercy will announce the winner next week at the State of the City address.
