The current level of fossil fuel carbon output is around 9.9 billion tons a year according to the U.S. EPA. Humans have destroyed around 1.9 billion hectares of forests worldwide. The average carbon sequestration per hectare/year of old growth rainforests is around 10,000 pounds. Those 2 billion hectares of forests would be absorbing nearly the entirety of our current fossil fuel carbon output every year had they not been destroyed. In other words, human fossil fuel emissions are not the main problem. It is the reckless destruction of the Earth’s carbon sinks that are causing CO2 levels to rise.*
It can take decades for a forest to reach a carbon sequestration level of 10,000 pounds/hectare/year. However, bamboo can actually absorb more than double the carbon of old growth rainforests within months of being planted. The average carbon absorption per hectare/year of certain bamboo species is over 22,000 pounds of carbon.
If slightly more than half of the deforested land was planted with bamboo, 100% of global fossil fuel carbon emissions would be offset in a matter of months and reverse the climbing CO2 levels. The cost to subsidize 1 billion hectares of land to grow bamboo is estimated to average around $600 per hectare, or $600 Billion per year. Less than the US military budget.
The CooBoo program is a voluntary, donation based concept with the goal of sequestering fossil fuel CO2 output through subsidizing the growing of bamboo forests.
*9.9 billion tonnes is 21.8 Trillion pounds of CO2. 1.9 billion hectares of forest absorbing 10,000 pounds per hectare per year is equal to 19 Trillion pounds. 1 billion hectares of bamboo absorbing 22,000 pounds per hectare/year is 22 Trillion pounds.
