IEA helps to inform the debate on climate change leading up to Doha

To HomepageIn the lead-up to the UN climate negotiations in Doha, the latest information on the level and growth of CO₂ emissions, their source and geographic distribution will be essential to lay the foundation for a global agreement. To provide input to and support for the UN process the IEA is making available for free download the “Highlights” version of CO Emissions from Fuel Combustion.

This annual publication contains:

–       Estimates of CO₂ emissions by country from 1971 to 2010

–       Selected indicators such as CO₂/GDP, CO₂/capita, CO₂/TPES and CO₂/kWh

–       CO₂ emissions from international marine and aviation bunkers, and other relevant information

These estimates have been calculated using the IEA energy databases and the default methods and emission factors from the Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories.

Key findings include:

* Global CO2 emissions rose by 4.6% in 2010, after having declined in 2009 due to the impact of the financial crisis, in particular on Western economies.

* Emissions in Annex I countries increased by 3.3% in 2010 after falling sharply in 2009, while emissions in non-Annex I countries continued to increase rapidly (5.6%).

* Nearly two-thirds of global emissions for 2010 originated from just ten countries, with the shares of China (23.8%) and the United States (17.7%) far surpassing those of all others.

*The combined share of electricity and heat generation and transport represented nearly two-thirds of global emissions in 2010.

The PDF version of the Highlights and the full-scale study will be released on 13 November 2012.
