About the Benefits Calculator
The Tree Benefits Calculator is a promotional tool based on information from the "Tree Guidelines for San Joaquin Valley Communities" by McPherson, Simpson, Peper, and Xiao, U.S. Forest Service, Center for Urban Forest Research, March 1999 and the Sacramento Tree Foundation. The calculator assumes an average mix of small, medium, and large trees in the Sacramento region, as well as an average mix of public and private trees.
National Tree Benefits Calculator
For a more precise calculation of an individual tree's benefits based on species and location, visit the National Tree Benefits Calculator.
The National Tree Benefits Calculator was conceived and developed by Casey Trees and Davey Tree Expert Co.

Energy Savings (learn more)
Trees help us save energy by
- Shading our homes, helping us conserve our energy use for air conditioning in summer months.
- Releasing water vapor into the air, which makes our air cooler.
- Sheltering our homes from cold northerly winds, helping us conserve heat in winter months.
Properly planted shade trees can reduce summer cooling costs by 30%
Cleaner Air (learn more)
Trees clean our air by
- Pulling pollutants, like ozone and nitrogen oxides, directly from the air.
- Capturing harmful particulate matter, like dust, ash, pollen, and smoke, on leaf surfaces.
- Providing clean oxygen for us to breath.
One large tree provides enough oxygen for four people to breath.
Carbon Dioxide (learn more)
Trees reduce the amount of climate changing carbon dioxide (CO2) by
- Directly storing CO2 in their wood and leaves.
- Sheltering our buildings and reducing the demand for heating and air conditioning, which mean less CO2 in the production of energy.
Over it's lifetime, a single large tree soaks up about 5.5 metric tonnes of carbon. That is about equal to the yearly carbon emission of an average car in the Canada.
Water Quality (learn more)
Trees improve our water quality by
- Capturing rainfall on leaves and branch surfaces, which helps reduce runoff and protects us from flooding.
- Giving water a chance to sink into the ground, recharging our underground water stores.
- Reducing erosion by keeping rain from washing soil away from barren surfaces.
One large tree can capture over 1,800 litres of storm water every year.
About London's Million Tree Challengeour partners
Watch the New Million Tree Challenge Video
London's Million Tree Challenge calls on Londoners to plant one million trees over the next ten years. To kick this campaign off, we begin with a three-year goal of planting one tree for every Londoner. 2011 is the International Year of the Forest - a fitting year to begin a project that will benefit our city for generations.
London's legacy to the future can be found in our identity - The Forest City. London can be, and should be, among the best-treed communities in Canada, but we need to step up our efforts and everyone needs to contribute to create the greenest and healthiest London ever.
London's Million Tree Challenge is an initiative of ReForest London and the City of London as the founding partners. We seek additional partners to pledge to plant trees and to promote tree planting and care within their organizations. Each partner can develop programs that fit their own organization's culture and interests. Become a partner and join the challenge today!
