Devolved administration greenhouse gas inventories

Bookmark and Share
  • Release date: 10 June 2014
  • Period covered: 1990-2012
An annual report, produced by the National Atmospheric Emissions Inventory, includes emisson estimates for greenhouse gases.

The report presents estimates of greenhouse gas emissions for the constituent countries of the UK on both ‘by-source’ and ‘end-user’ basis. Separate greenhouse gas emission inventories have been estimated for England, Scotland, Wales and Northern Ireland for the years 1990, 1995 and 1998 to 2012.

The information published in this report will be used to assess the Welsh Government’s performance on its commitment to reduce emissions in Wales by 3 per cent per year in areas of devolved competence, against the baseline of 2006-2010 emissions.

The full report is available via the NAEI and UK Air websites.

Key points

  • Overall, since the base year (1990/1995), emissions of the basket of greenhouse gases have generally fallen.
  • In 2012 it was estimated that emissions totalled 45.8 million tonnes of carbon dioxide (CO2) equivalent, a fall of 18 per cent compared to base year emissions.
  • There was a 5 per cent increase of greenhouse gas emissions in 2012 compared with 2011; this was largely due to an increase in the energy sector which may have been affected by a shift from natural gas back to coal.
  • The main source of emissions continues to be the energy sector which produces around 42 per cent of all greenhouse gas emissions; in comparison, business is the second biggest source, accounting for 17 per cent of emissions in 2012.
  • Wales has a higher proportion of traded emissions covered by the EU Emissions trading Scheme than the rest of the UK, referred to as the ‘traded’ sector; this reflects the high share of heavy industry and electricity generation in Wales (e.g. emissions from power stations, refineries and integrated iron and steelworks) and as a result, 46 per cent of the total CO2 emissions in Wales were produced by the ‘non-traded’ sector in 2012.
  • When considering emissions from end users as opposed to energy producers, for example emissions from power stations are re-allocated to users of electricity, it is estimated that, with exclusion of emissions associated with energy exports, Wales has seen a fall of 32 per cent since the base year.
  • Wales has a lesser share of UKs end user emissions compared to the by source estimates, and has achieved higher emission reductions since the base year than the by source inventories indicate.

Please note these figures are not classed as National Statistics.

In early 2014 we consulted on the way in which we signpost users to statistics published by another official statistics producers. As a result, in future key points for Wales for these statistics will no longer be published, however the information will still be available from the Department of Energy & Climate Change via the Gov.UK website.

We will continue to provide information to users about how to locate the published data.
