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).
The 2.6 per cent rise projected for 2012 means global emissions from burning fossil fuel are 58 per cent above 1990 levels, the baseline year for the Kyoto Protocol.

This latest analysis by the Global Carbon Project is published today in the journal Nature Climate Change with full data released simultaneously by the journal Earth System Science Data Discussions.
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.
It shows previous energy transitions in Belgium, Denmark, France, Sweden, and the UK have led to emission reductions as high as 5 per cent each year over decade-long periods, even without climate policy.
Lead author Dr Glen Peters, of the Centre for International Climate and Environmental Research in Norway, said: “Scaling up similar energy transitions across more countries can kick-start global mitigation with low costs. To deepen and sustain these energy transitions in a broad range of countries requires aggressive policy drivers.”
Prof Trevor Davies, Director and Chair of the Fudan Tyndall Centre in Shanghai, said: “Historically, other countries have been responsible for building up the burden of carbon dioxide in the atmosphere. But the challenge, today, is one for all countries to face. The innovation we find in China, together with its science and technology expertise, means that the country could grasp a major leadership role in facing up to this global challenge”.
Prof Jianmin Chen, Director of the Fudan Tyndall Centre, said: “ Something like 30% of China’s carbon emissions are related to goods consumed in other countries, and so the global pattern of responsibilities is complex, but the progress China is making in urban air pollution levels show what we are capable of when, as a nation, we put our minds to big challenges”.
Co-author Dr Charlie Wilson, of the Tyndall Centre at UEA, added: “Public policies and institutions have a central role to play in supporting the widespread deployment of low carbon and efficient energy-using technologies, and in supporting innovation efforts”.
Emissions from deforestation and other land-use change added 10 per cent to the emissions from burning fossil fuels. The CO2 concentration in the atmosphere reached 391 parts per million (ppm) at the end of 2011.
These results lends further urgency to recent reports that current emissions pathways are already dangerously high and could lead to serious impacts and high costs on society. These other analyses come from the International Energy Agency, the United Nations Environment Programme, the World Bank, the European Environment Agency, and PricewaterhouseCoopers.
