Latest projections of non-CO2 greenhouse gases out to 2030.
Change to the publication frequency and timeline for the non-CO2 projections
The frequency and publication date of the non-CO2 projections are due to change for 2014. The current arrangement is to produce the non-CO2 projections twice a year, on the 15th of March (the Spring Update) and the 15th of September (the Autumn Update). The Spring Update incorporates the latest Greenhouse Gas Inventory as well as some projections data updates, the Autumn Update incorporates only projections data updates and some methodological improvements. The changes are being made in order to improve the timing and delivery of non-co2 projections to our major users and to allow more focus on improvements to the projections.
The changes proposed are:
- The non-CO2 projections change from a biannual update cycle to an annual one.
- The publication date for this single annual update is shifted to late July
- This change in publication timeline becomes effective immediately, with the next set of projections to be published by the team on 31st July 2014.

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.
