National and International Data Availability and Sources: National 
communications from Parties to the Convention are available. Developing countries 
report on a limited basis. At the international level, the UNFCCC Secretariat database 
has information based on annual data inventory submissions from Annex I Parties to 
the Convention (see http://ghg.unfccc.int/). 
As part of the review process of the UNFCCC, emission levels were initially available 
only for Annex I Parties to the Convention. Non-Annex I Parties have also started to 
submit first-hand information on their annual GHG emissions. 
The International Energy Agency (IEA) provides data on CO
2
emissions by fuel and 
sector, and from fossil fuels consumed for electricity, combined heat and power, and 
district heating. Data are calculated using the IEA's Energy Balance Tables and the 
Revised 1996 IPCC Guidelines. 
The World Bank compiles data on annual anthropogenic emissions of CO
2
. These 
data originate from calculations by the Carbon Dioxide Information Analysis Center 
(CDIAC), sponsored by the US Department of Energy. The calculations are derived 

---

90 
from data on fossil fuel combustion, based on the World Energy Data Set maintained 
by the UN Statistics Division, and from data on world cement manufacturing, based 
on the Cement Manufacturing Data Set. To derive data on the quantity of CO
2
emissions from energy use only, the amounts of CO
2
from cement manufacturing 
have to be subtracted from the World Bank’s data on CO
2
emissions. 
(c) Data References: The IEA data on CO
2
emissions by fuel and sector, and from 
electricity and heat generation are reported in the IEA publication CO
2
 Emissions 
from Fuel Combustion, published annually. Data on total CO
2
emissions from energy 
and industrial sources are available from the World Bank report World Development 
Indicators, published annually. Data on CH
4
and N
2
O are not available. GHG 
emissions data for the European Union are available from the European Environment 
Agency Web site (http://dataservice.eea.eu.int/dataservice/metadetails.asp?id=699).
