Introduction to Greenhouse Gas Emissions and the UK Inventory
Why do we need a Greenhouse Gas Inventory?
The world is responding to the challenge of climate change. The United Nations Framework Convention on Climate Change (UNFCCC) was ratified by the United Kingdom in December 1993 and came into force in March 1994. Parties to the Convention are committed to develop, publish and regularly update national emission inventories of greenhouse gases (GHGs). Under the convention, all developed countries agreed to return their GHG emissions to 1990 levels by 2000. Further to this, the UK has a legally binding target under the Kyoto Protocol to cut GHG emissions by 12.5% below 1990 levels by 2008-2012.
The UK Government’s Greenhouse Gas Inventory is the means by which the UK’s progress towards achieving these targets is assessed by international bodies, as well as providing the formal reporting system for EU and UN reporting requirements.
For more information on climate change and the UK’s strategy towards emission reductions, visit the Defra website or read the latest National Inventory Report.
How is the Inventory Maintained & Updated?
The UK Greenhouse Gas Inventory is developed and maintained by AEA. The work is carried out under contract with Climate Energy & Ozone: Science & Analysis Division (CEOSA) of the UK Department for Environment, Food & Rural Affairs (Defra).
The GHG inventory provides an independent estimate of the UK’s GHG emissions for reporting to the UNFCCC, and is updated annually. To deliver these estimates, the GHG inventory team at AEA collect and analyse information from a wide range of sources – from national energy statistics through to data collected from individual industrial plants.
