The Tree Equity Score tool was created to help address damaging environmental inequities by prioritizing human-centered investment in areas with the greatest need. This tool measures how well the critical benefits of urban tree canopy are reaching those who need them most. Each score indicates whether there are enough trees in a neighborhood for everyone to experience the health, economic, and climate benefits that trees provide. Scores are based on tree canopy, surface temperature, income, employment, race, age, language, and health factors. These scores guide investment in communities living on low incomes, communities of color, and all those disproportionately affected by extreme heat, pollution, and other environmental hazards.
