Global carbon dioxide (CO2) emissions are set to rise again in 2012, reaching a record high of 35.6 billion tonnes – according to new figures from the Global Carbon Project, co-led by researchers from the Tyndall Centre for Climate Change Research at the University of East Anglia (UEA).
It shows the biggest contributors to global emissions in 2011 were China (28 per cent), the United States (16 per cent), the European Union (11 per cent), and India (7 per cent).
Emissions in China and India grew by 9.9 and 7.5 per cent in 2011, while those of the United States and the European Union decreased by 1.8 and 2.8 per cent.
Emissions per person in China of 6.6 tonnes of CO2 were nearly as high as those of the European Union (7.3), but still below the 17.2 tonnes of carbon used in the United States. Emissions in India were lower at 1.8 tonnes of carbon per person.
Prof Corinne Le Quéré, director of the Tyndall Centre for Climate Change Research and professor at UEA, led the publication of the data. She said: “These latest figures come amidst climate talks in Doha. But with emissions continuing to grow, it’s as if no-one is listening to the entire scientific community.”
The 2012 rise further opens the gap between real-world emissions and those required to keep global warming below the international target of two degrees.
“I am worried that the risks of dangerous climate change are too high on our current emissions trajectory. We need a radical plan,” added Prof Corinne Le Quéré.
The analysis published in Nature Climate Change shows significant emission reductions are needed by 2020 to keep two degrees as a feasible goal.
