Details

We provide 3 sets of conversion factors:

• condensed set: this abridged version of the full set is easiest to navigate and most frequently requested. It’s 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: not recommended for most users, it contains the same information as the full set, but is arranged for automated processes. Flat files only available from 2014 onwards

The methodology paper explains how the conversion factors are derived.

New users should 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. This highlights the most significant changes to the conversion factors for that update, and so will ensure that reporting is consistent and comparable year-on-year.

Defra’s Environmental reporting guidelines provide more detail.
