New inventory of black carbon emissions from China finds 2007 levels higher than previously reported

Green Car Congress

for year 2007. A new black carbon (BC) emissions inventory from China found BC emissions levels in 2007 of 1,957 Gg BC—higher than reported in earlier studies. Black carbon is released into the atmosphere via incomplete combustion of carbonaceous fuel and is of major concern because of the impact on climate systems.

Perspective: The UN Approval Process for Carbon Offsets

Green Car Congress

Since 2005, when major greenhouse-gas emitters among the Kyoto signatories were issued caps on their emissions and permitted to buy credits to meet those caps, there has been more than $300 billion worth of carbon transactions. The approval process for carbon offsets has two goals. THE APPROVAL PROCESS.
