Details

We provide two sets of conversion factors:

• Condensed set - most frequently requested by users. An abridged version of the full set of factors, designed to reduce the volume of information users need to navigate through to find the factors they want. Recommended for most users of conversion factors
• Full set: This set of factors contains all of the available factors for the selected year. This is recommended for advanced users due to the volume of information presented
• The methodology paper explaining how the conversion factors are derived.

For new users of the conversion factors, we recommend you download the condensed set of conversion factors from the latest available year and read the guidance in the document’s introductory sheet. Then follow the informative text at the top of each conversion factor tab in the output files. We also recommend reading guidance on emissions reporting such as Defra’s ‘Environmental reporting guidelines’. Then download the latest version of the condensed factor set.

For repeat users of the conversion factors we suggest that you download your preferred factor set and read the ‘what’s new’ sheet before using the conversion factors, which highlights the most significant changes to the conversion factors in this update. Following the ‘what’s new’ guidance will ensure that reporting is consistent and comparable year-on-year.
