Global CO2 emissions from fossil fuels have risen 29% since 2000, according to an international team of researchers. Compared to 1990, the Kyoto Protocol reference year, the rise is 41%.
The Global Carbon Project, writing in peer reviewed journal Nature Geoscience, also report a 2% increase in emissions during 2008 despite the economic downturn. However, this is less than the 3.4% average annual rate of increase over the same period.
The use of coal as a fuel now exceeds oil for the first time in 40 years and developing countries have overtaken their western counterparts in the amount of greenhouse gas emissions.
“The only way to control climate change is through a drastic reduction in global CO2 emissions,” says lead author Corinne Le Quéré of the University of East Anglia and the British Antarctic Survey.
However, she admits that researchers still don’t fully understand the links between human-induced CO2 emissions and atmospheric CO2 concentrations.
