Global CO2 emissions stalled for the third year in a row

Green Car Congress

Information on the other two greenhouse gases, methane (CH 4 ) and nitrous oxide (N 2 O), is only available until 2012, as international statistics on agricultural activities—the main source of these emissions—are not updated as frequently as on energy and industry-related activities. Other greenhouse gases keep creeping up.

Measurements of CO2 and CO in China’s Air Indicate Sharply Improved Combustion Efficiency

Green Car Congress

The findings, published in the 21 September issue of Atmospheric Chemistry and Physics , are generally consistent with official Chinese government statistics and could bolster their credibility as international negotiations proceed on commitments of China and other nations to combat climate change.

GCP Carbon Budget Finds Anthropogenic CO2 Emissions Rose 2% in 2008 Despite Global Financial Crisis; Natural Sinks Not Keeping Pace With Increasing Emissions

Green Car Congress

Using a variety of data including direct observations, computer-generated models, and estimates from countries’ energy statistics, the team created a global CO 2 budget—the amount of CO 2 produced and consumed—from 1959 to 2008. between 2000 and 2008, compared with 1% per year in the 1990s. —Dr Canadell.
