Emission Factors
 
 
 
The Department for Environment, Food and Rural Affairs (Defra) is responsible for the delivery of the UK Government's Greenhouse Gas Inventory (GHGI) to the United Nations Framework Convention on Climate Change (UNFCCC). In this capacity, Defra is required to establish a National System for inventory data provision, in accordance with Article 5 of the Kyoto protocol and European Commission Decision 280/2004/EC, in order to support compliance with the UK and EU's Kyoto Protocol commitments.
 
To ensure the consistency and accuracy of data used within the GHGI, now and into the future, Defra is developing the UK's National System through the implementation of contracts and agreements with key data providers.
 
Emission Factors
 
References sources for emission factors for many industries are researched by environmental institutions around the world. Many of the key sources of emission factor data that are incorporated into the UK GHGI are as follows:
 
EMEP-CORINAIR GUIDEBOOK
http://reports.eea.eu.int/EMEPCORINAIR4/en
 
USEPA AP-42
http://www.epa.gov/ttn/chief/ap42/index.html
 
IPCC Guidebook
http://www.ipcc-nggip.iges.or.jp/public/gl/invs1.htm
 
In addition, many of the key data providers such as DTI Energy Group, UKPIA, Corus and JEP provide additional information regarding emission factors pertinent to specific fuels and processes.
 
AEA also manages a programme of emission factor review and improvement, the findings of which can be found at www.naei.org.uk/data_warehouse.php.
 
A key component of the UK GHGI dataset is the carbon emission factors applied to fuel use data, and this impacts upon the data utilised by the EU Emissions Trading Scheme, as many default factors for the EU-ETS are derived from the UK's national inventory. Summary data for carbon emission factors, published in April 2005, can be found at http://www.naei.org.uk/report_link.php?report_id=417
