Trees scattered across our towns and communities save about 7.2% in annual residential energy savings ($7.8 billion). That also results in less power plant emissions (valued at about $3.9 billion). These estimates are on top of reducing air pollution (valued at $4.7 billion) and sequestering CO2 (valued at $2 billion).
Estimates were calculated for the 6.4% of land in the U.S. that’s developed into cities/communities. The value trees provide is much higher in more densely populated areas, and less in more suburban areas and rural cities. It also follows that the maintenance and economic costs of trees vary significantly by type of tree and climate, so results will vary based on where they’re planted.
Authors of the study say their results are modeled and estimates only. Quantifying the benefits of trees at the state and local level through field work will improve understanding of the role trees play and improve the estimates.
