Emissions projections are used as a way of monitoring progress towards the UK’s emission reduction targets. The government has set targets for reductions in greenhouse gas emissions out to 2050. Therefore a regularly updated set of projections is required as UK policy and understanding of likely future emissions evolves.
The UK is also required to submit projected emissions of greenhouse gases biennially under the European Union Monitoring Mechanism, and periodically in the form of National Communications to the United Nations Framework Convention on Climate Change (UNFCCC).
The projections which accompany this report are for the non-CO2 component of the Kyoto Protocol’s basket of greenhouse gases (GHG) and are collectively referred to as the non-CO2 GHGs. These are:
- methane (CH4)
- nitrous oxide (N2O)
- hydrofluorocarbons (HFCs)
- perfluorocarbons (PFCs)
- sulphur hexafluoride (SF6)
The HFCs, PFCs and SF6 are also collectively known as the ‘F-Gases’.
Projected emissions of CO2 are reported in DECC’s Updated Emissions Projections and are not included within the coverage of this report or associated projections.
Previous editions of the projections can be accessed on the National Archives website.
