On average, a mature tree can absorb about 48 pounds (21.77 kg) of CO2 per year. Over a 40-year lifespan, this amounts to about 1 ton (907 kg) of CO2.

• One acre of forest can absorb about 2.5 tons (2,268 kg) of CO2 annually .

• Urban trees can also contribute significantly to CO2 absorption. An urban tree can sequester 1 to 4 tons of CO2 over its lifetime.

• Forests in the United States collectively sequester approximately 866 million metric tons of CO2 annually, which is about 16% of the nation's CO2 emissions .

• Tropical forests are particularly effective, absorbing more CO2 per hectare than temperate forests.
