Statistical Databases: CO2 Emissions from Fuel Combustion

CO₂ Emissions from Fuel Combustion - IEA Online Database

Recent years have witnessed a fundamental change in the way governments approach energy-related environmental issues. Promoting sustainable development and combatting climate change have become integral aspects of energy planning, analysis and policy making in numerous countries, including all IEA members.

The database assists in better understanding the evolution of CO₂ emissions from fuel combustion from 1960 onwards for OECD/IEA countries and from 1971owards for non-OECD/IEA countries by sector and fuel.

The estimates of CO₂ emissions from fuel combustion presented in this database are calculated using the IEA energy data and the default methods and emission factors from the Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories. There are many reasons why the IEA estimates may not be the same as the numbers that a country submits to the UNFCCC, even if a country has accounted for all its energy use and correctly applied the IPCC Guidelines.

Since 2000 the IEA is presenting CO₂ emissions calculated using both the IPCC Reference Approach and the IPCC Tier 1 Sectoral Approach. In some of the non-OECD countries, there can be large differences between the two sets of calculations due to various problems in some energy data. As a consequence, this can lead to different emisssion trends between 1990 and 1999 for certain countries.

The database provides the following five data files:

• CO₂ Emissions from Fuel Combustion (detailed estimates) (Mt of CO₂)
• CO₂ Emissions from Fuel Combustion (Mt of CO₂)
• CO₂ Indicators
• Emissions per kWh and Electricity (TWh) and Heat Output (TWh)
• Per Capita CO₂ Emissions by sector
