Carbon sequestration rates are up to 90 times greater for healthy large trees than healthy small trees. In Chicago's urban forest, a typical 3-in diameter tree sequesters approximately 2.3 lbs annually, which is equivalent to carbon emissions of a passenger vehicle driven 10 miles. Annual sequestration by a 30-in tree is around 204 lbs per year, the carbon emissions of a passenger vehicle driven approximately 900 miles.

The LPS Fast Fact Library is a collection of short summaries of landscape benefits derived from published research. The Landscape Architecture Foundation (LAF) compiles and writes the Fast Facts. LAF has no involvement in the data collection, analysis, review, publication, or funding of the research.
