A2ZERO Annual Report Highlights Three Years of Impact

Archived News Release: June 12, 2023 - ​Ann Arbor's aggressive climate and sustainability plan and framework, called A2ZERO, just rounded out its third year and celebrated with a weeklong series of events (A2ZERO Week) and the release of an annual report looking at major activities and accomplishments achieved in the first three years of the plan. The third-year report highlights the work of the Ann Arbor Office of Sustainability and Innovations, collaborating city departments and dozens of community collaborators, such as:

  • Installation of over 4 megawatts (MW) of rooftop solar through Ann Arbor Solarize and the creation of a new Commercial Solar Program in collaboration with the Ann Arbor 2030 District.

  • Initiation of solar at city facilities, which, when complete, will lead to 4MW of new solar at municipal sites.

  • Designed and currently piloting a Home Energy Advisor Service with Elevate and EcoWorks to assist residents with home decarbonization.

  • Held the first annual Electrification Expo with 25 vendors and around 450 attendees; the second expo is planned for August 2023.

  • Supported 20% of the city's light-duty fleet with transitioning to electric.

  • Launched an initiative to investigate options to sustainably heat the entire community.

  • Secured grants to support more solar installation at city facilities, advance net-zero energy affordable housing, conduct a geothermal study in the community, launch the state's first utility-pole charging pilot, advance work to make the 262 homes surrounding the Bryant Community Center carbon neutral, and transition all city streetlights to LEDs, among others.

  • And much more!

“Year three ​was an amazing year for A2ZERO … and year four looks even more extraordinary," said Dr. Missy Stults, sustainability and innovations director for the city. “We are honored to work with so many individuals, organizations and collaborators to help usher in a more just, equitable and sustainable community for all Ann Arborites and look forward to working with many more as A2ZERO grows."
