Non-OECD Coal Responsible for Most Global Emissions Increase
The International Energy Agency (IEA) last week published global data for emissions from fuel combustion for 2007-2008.
It shows that CO2 emissions in Annex 1 countries decreased by more than 2% in 2008, whereas emissions in developing (Non-OECD) countries rose by almost 6%. Most of this increase was due to increased emissions from coal.
Fossil fuels still account for 81% of world primary energy supply, down only marginally on a relative share basis from 88% in 1971. In developed countries, greenhouse gas emissions accounted for 83% of all anthropogenic emissions in 2008.
China is now the highest emitter, and since 1990 has almost tripled emissions from a little over 2Gt CO2, to over 6Gt CO2.
In the past six years China showed dramatic growth in CO2 emissions from electricity and heat generation, which represents 48% of China’s CO2 emissions in 2008.
While the IEA projects that China’s emissions growth rates will slow to 2.9% out to 2030, at that date emissions will be almost twice current levels.
