Details

We provide 3 sets of conversion factors:

Condensed set: most frequently requested. An abridged version of the full set of factors which is easiest to navigate. Recommended for most, and new, users of conversion factors.

Full set: all the available factors for the selected year, recommended for advanced users only due to the volume of information.

Flat file set: same information as the full set, but arranged for automated processes. Not recommended for most users. This fileset is only available from 2014 onwards.

We recommend that new users read the introductory guidance in the latest condensed set of conversion factors, then follow the text at the top of each conversion factor tab in the output files.

Repeat users should read the ‘what’s new’ sheet before using the conversion factors, which highlights the most significant changes made to the conversion factors for that update. This will ensure that reporting is consistent and comparable year-on-year.

The methodology paper explains how the conversion factors are derived. The major changes report summarises large changes in individual factors since the last edition. The statement of voluntary compliance with the Code of Practice for Statistics outlines how the conversion factors adhere to the pillars of trustworthiness, quality and value as set out in the Code.

Defra’s Environmental reporting guidelines provide more detail.
