The estimates of CO2 emissions from fuel combustion presented in this publication are calculated using the IEA energy data1 and the default methods and emission factors from the Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories, IPCC/ OECD/IEA, Paris, 1997 (1996 IPCC Guidelines).
Although the IPCC approved the 2006 Guidelines at the 25th session of the IPCC in April 2006 in Mauritius, most countries (as well as the IEA Secretariat) are still calculating their inventories using the 1996 IPCC Guidelines.
The IEA Secretariat reviews its energy databases each year. In the light of new assessments, important revisions may be made to the time series of individual countries. Therefore, certain data in this publication may have been revised with respect to previous editions.
