Cities, states, and organizations across the country are using GEM to reduce their carbon emissions, upgrade the grid through energy efficiency and clean power sources, channel funding towards disinvested communities, and advance community-driven processes.

GEM's data come from both public and proprietary sources and are reviewed by researchers from the Georgia Institute of Technology, the University of Michigan, the University of Wisconsin Madison, and the University of California Los Angeles.

Non-white communities are disproportionately harmed by environmental and socioeconomic hazards and are far more likely to live in areas with extreme weather events, heavy pollution, fragile infrastructure, and high energy bills.

We seek to correct the flawed policies that led to these conditions and advise regulations that work to create regenerative, inclusive, and fair neighborhoods for all.

To get there, city and state governments need to approach climate solutions through a racial equity lens and work collaboratively with the communities most negatively impacted. Community-driven climate policies foster long-term solutions while avoiding collateral damage that comes without community buy-in.
