In the lead-up to the UN climate negotiations in Lima, 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. This annual publication contains, for more than 140 countries and regions: estimates of CO2 emissions from 1971 to 2012; selected indicators such as CO2/GDP, CO2/capita, CO2/TPES and CO2/kWh; a decomposition of CO2 emissions into driving factors; and CO2 emissions from international marine and aviation bunkers, key sources, and other relevant information. The twentieth session of the Conference of the Parties to the Climate Change Convention (COP 20), in conjunction with the tenth meeting of the Parties to the Kyoto Protocol (CMP 10), will be meeting in Lima, Peru from 1-12 December 2014. This volume of "Highlights", drawn from the full-scale study, was specially designed for delegations and observers of the meeting in Lima.
