A mature Bradford pear similar to the one above
was found to store approximately 306 kg (676 lb)
of CO2 in aboveground biomass.
- Trees use carbon dioxide when they grow and, thus, remove it from the air. A major report on this carbon sequestration benefit in urban forests is Carbon dioxide reduction through urban forestry: Guidelines for professional and volunteer tree planters, by Gregory E. McPherson and James R. Simpson.
- The energy saved by trees and the resultant reduced demand for power, lowers the carbon dioxide emissions from power plants.
- A hypothetical planting of 100 million trees would save 22 billion kilo-watt hours and 33 million tons of carbon dioxide annually after 10 years (Akbari and others 1990).
- Portland’s Friends of the Trees has planted over 300,000 trees. Once mature, their surviving trees and seedlings are estimated to sequester 73,000 tons of carbon dioxide at a cost of about $31 per ton.
- Reductions of carbon dioxide achieved through urban shade tree programs could offset about 0.2 to 2% of annual industrial emissions.
