Due to concerns about global warming and rising sea levels, some companies have come up with ways to offset carbon dioxide emissions. For some companies, the cost of sponsoring a renewable energy project is too high [more than $ 5 per ton of carbon dioxide emissions]. US per capita carbon dioxide emissions are about 20 tonnes of carbon dioxide per year [based on an estimated 6 billion tonnes and an estimated population of 300 million people], so we expect the following typical US residents to: I can not do it. If it costs $ 100 a year, you can sponsor your carbon offset program.
Most companies that considered options to support afforestation as a way to reduce carbon dioxide emissions faced three questions.
[1] What kind of tree do I need to sponsor? And how much carbon can a typical tree absorb every year?
Much of that information was developed around 1980 by the US State Organization on behalf of the power industry and other related groups. It was also developed by Dr. Paiul Faeth, a consulting firm at the University of Oregon and Washington, DC. Resources Management International [RMI] was the foundation of a Guatemala carbon reduction project funded primarily by the US government on behalf of Applied Energy Services, an electricity service organization in Arlington, Virginia.
The project planted 54 million trees, mostly Leucaena leucocephala, which is enough to remove more CO2 from the atmosphere each year than is released annually from plants in Uncasville, Connecticut, USA . A second project representing New England Electric Service [NEES] followed immediately.
The information comes from a study of this type of annual growth under conditions similar to those encountered in Guatemala, and various parts of these trees were weighed annually [trunks, branches, roots, leaflets, leaf]. The discovery was that such a tree removed about 53 pounds each year. The CO2 US Congress later simplified the calculation to 50 pounds and concluded that 40 such trees would remove and sequester 1 ton [2,000 pounds] of CO2 each year.
Some agronomists believe that this number may be conservative. Some trees provide additional benefits to the soil, resulting in increased undergrowth. Trees also continually drop leaves-for example, these Leucaena Trees drop as much as 15 tons of leaves per hectare per year. As such, it is worth about 20 pounds. Carbon per tree every year. Some of those leaves rot into soil and are added to the roots of the forest.
[2] How can I check that trees are really planted?
This problem was enough to kill most tree planting activities by green marketers in the late 1990s. Because there was no easy way to confirm that the tree was actually planted. As described later in this article, there are currently available options thanks to GPS.
[3] How can I confirm that trees are still 10 years from now? An incentive program can be installed in a place to monitor trees and can offer specific rewards if the local village can prove that the planted trees have matured. For example, some tree planting organizations have linked new school donations to the success of protecting newly planted areas.
Before finishing this discussion, it may be interesting to discuss the “forest garden” approach proposed by the plantation organization in Silver Spring, Maryland. taller than. The forest garden itself is a “bankable” project [local farmers get more immediate income from vegetables than from trees], and the sequestered carbon also has market value, so it is profitable Companies through this system may be able to reduce atmospheric carbon.
