Summary of CO₂ Emissions from Fuel Combustion

Core Content

The International Energy Agency (IEA) is an autonomous agency established in 1974, dedicated to promoting energy security and providing authoritative research on reliable, affordable, and clean energy. Its mission includes supporting sustainable energy policies, improving market transparency, and fostering global collaboration on energy technology to reduce greenhouse gas (GHG) emissions and mitigate climate change.

The IEA's 2016 publication on CO₂ emissions from fuel combustion offers comprehensive data for over 150 countries and regions, covering emissions by fuel, sector, and region, as well as key indicators like emissions per GDP and per capita. This data is based on official energy statistics and the 2006 IPCC Guidelines for National Greenhouse Gas Inventories.

Main Points

• Energy and Climate: Energy use accounts for two-thirds of total GHG emissions and 80% of CO₂ emissions. CO₂ emissions from fuel combustion are the largest contributor to global anthropogenic GHG emissions, making the energy sector a critical focus for climate action.

• Global Emissions Trends:

  • In 2014, global CO₂ emissions from fuel combustion reached 32.4 GtCO₂, a 0.8% increase from 2013, the lowest growth since 2000.
  • Non-Annex I countries accounted for 58% of global CO₂ emissions in 2014, while Annex I countries contributed 39%, and international marine and aviation bunkers accounted for 3%.
  • Emissions in non-Annex I countries tripled since 1990, whereas Annex I emissions slightly decreased.

• Fuel Contributions:

  • Coal was the largest contributor to CO₂ emissions, despite accounting for only 29% of the world's total primary energy supply (TPES), due to its high carbon content.
  • In 2014, coal accounted for 46% of global CO₂ emissions, while oil and natural gas contributed 34% and 20% respectively.
  • The share of coal in global emissions increased from 39% in 2002 to 46% in 2014, while the share of oil decreased.

• Regional Breakdown:

  • China (28%) and the United States (16%) were the top two emitters in 2014, together accounting for 14.3 GtCO₂.
  • The top ten emitting countries included five Annex I and five non-Annex I countries.
  • Emissions per capita varied widely, with the lowest in Africa and the highest in the United States (16.2 tCO₂).

• Sectoral Contributions:

  • Electricity and heat generation accounted for 42% of global CO₂ emissions from fuel combustion.
  • Transport emissions contributed 23%, with road transport being the largest contributor.
  • Emissions from international marine and aviation bunkers increased significantly, by 69% and 95% respectively, between 1990 and 2014.

• Decoupling and Efficiency:

  • Globally, CO₂ emissions increased by 58% between 1990 and 2014, driven by population and GDP growth.
  • Energy intensity decreased by 30% globally, but carbon intensity remained relatively stable, limiting decoupling.
  • In Annex I countries, emissions decreased by 8% from 1990 to 2014, with energy intensity falling 34% and GDP per capita increasing 39%.

• Key Indicators:

  • Emissions per GDP (using both exchange rates and purchasing power parities) and emissions per capita are important indicators for assessing the environmental impact of economic activity.
  • The IEA provides data on these indicators to support policy-making and international climate negotiations.

Key Information

• The publication includes data from 1971 to 2014 for over 150 countries and regions.
• Data is based on the IEA World Energy Balances 2016 and 2006 IPCC Methodologies.
• The IEA acknowledges collaboration with the PBL Netherlands Environmental Assessment Agency and the Joint Research Centre of the European Commission for additional data.
• The publication includes graphs and tables for regional and global aggregates, along with country notes detailing revisions to data, especially from the People's Republic of China.
• The IEA offers data services via its website and CD-ROM for comprehensive data access.

Conclusion

The IEA publication provides essential insights into the trends and drivers of CO₂ emissions from fuel combustion, highlighting the growing role of energy in climate change and the need for sustainable policies. It serves as a critical resource for policymakers and stakeholders involved in global climate negotiations and energy planning.
