CO2 emissions rise again

A paper published in the Nature Geoscience journal as part of the Global Carbon Project has found that despite the deep financial crisis last year, carbon dioxide (CO2) emissions in 2009 dropped only 1.3 per cent on 2008 levels. This is less than half the drop that had earlier been predicted.

Drops in emissions in developed economies were offset by strong growth in many developing countries and an increasing reliance on coal. The carbon intensity of production, a measure of CO2 emissions per unit of GDP, dropped by just 0.7 per cent in 2009, well below the long term average of 1.7 per cent per year.

The study also predicts that global CO2 emissions have risen by 3 per cent in 2010, a return to the high growth rates of emissions between 2000 and 2008.
