What emerged from the Kyoto meeting is that as each country produces CO2, it must be able to contain that CO2 by tree-planting or other processes that can absorb it, such as sequestration and changing farming methods. Or it can reduce the CO2 it produces in the first place. If that country produces more CO2 than it can absorb, it must purchase an ‘absorption ability’ from another nation. The Carbon Credit is this new currency and one Carbon Credit is equal to one Tonne of CO2 and is called a CO2e (CO2 equivalent). A nation might have a shortfall in absorbing 500,000T of CO2 and according to the Kyoto agreement it must seek to purchase those from another nation that has been planting trees for such a consideration. Costs are between US (ironically) $10 – 40 per credit.
So, Algore, show us the receipts!
...BTW: isn't the accelerated planting of trees, beyond their natural growth patterns, environmentally harmful? I mean it does tamper with the natural order...
