Provides files to download data as it existed for this dataset on previous dates.

Statistics are most often revised for 1 of 2 reasons:

  1. For certain statistics initial estimates are released with the expectation that these may be revised and updated as further data becomes available.
  2. Revisions may also be made when methods or systems are changed.

These types of planned revisions should not be confused with errors in released statistics, which are genuine mistakes. Such mistakes occur rarely and, when they do happen, corrections are made in a timely manner, announced and clearly explained to users in line with the Code of Practice for Official Statistics (Principle 2, Practice 7).

In the cover sheet of the dataset we have changed the wording in the notes section and included additional notes to make the information clearer, the data have not been affected.

We have corrected an error in the dataset. The annual sum across the quarters for the seasonal adjusted time series was not equal to the annual sum across the quarters for the non-seasonal time series. This happened because of a processing error.

Important notes and usage information

  • These experimental estimates of greenhouse gas emissions have been modelled using the Chow-Lin regression based temporal disaggregation method. 

  • Currently, all the predictor indicators used in our modelling are taken from the  Department for Energy Security and Net Zero (DESNZ), Energy trends publication.

  • The seasonally adjusted emissions estimates are modelled using X13ARIMA-SEATS.

  • These estimates are experimental - their methodology is under development and so these estimates are subject to change.

  • The Air Emission Accounts include only direct emissions, defined as 'scope 1' under the GHG protocol guidance.

  • Due to the method used to estimate these series, quarterly estimates of greenhouse gas (GHG) and carbon dioxide (CO2) emissions from consumer expenditure should not be calculated by subtracting the estimates of GHG/CO2 emissions minus consumer expenditure (Table 2 and 4) from the total GHG/CO2 series (Table 1 and 3).

  • Consumer expenditure refers to the consumption of fuels and other products by individuals in the UK, as opposed to the production of these by industry.

  • Emission intensity is calculated as the total emissions divided by gross valve added at basic prices, chained volume measures with (2019) as the base and reference year.
