Carbon Sequestration by Trees

Saturday, January 19th, 2008 (New Projects)

“The issue of sequestration is very complicated. Sequestration rates vary greatly according to the age, composition, and location of the forests and the type of soil.”

See the following website for data

Mitigation as not as crucially important as reduction in emissions. All strategies are needed at this point. See:

Though there are strong arguments for ecosystem services that trees provide, if the right ones are selected. The issue of water consumption also plays a large role as both young trees require a lot of it and trees in general may alter hydrology.

Explaining CO2-e (carbon dioxide equivalents)

Different greenhouse gases have differing abilities to warm the planet (“global warming potential”). To enable us to estimate how much a given mass of greenhouse gas is estimated to contribute to global warming, the gas is compared to a baseline of one unit by weight of carbon dioxide (CO2), and is expressed in “carbon dioxide equivalent” (CO2-e). Many scientists also calculate the amount of carbon stored as carbon (C). To convert to CO2 or CO2-e, multiply by 44/12.

For example, methane (CH4), another common greenhouse gas, has a global warming potential 21 times that of CO2.
