Methodology reference
Activity Data Guide
A structured reference for the activity data organisations collect when measuring a carbon footprint — definitions, units, GHG Protocol scope mappings, and sub-type depth. Numeric emission factors stay in the platform; this guide publishes the taxonomy consultants and procurement teams rely on.
How to use this guide
Each activity page follows the same five sections: what counts, what activity data you need (units), which emission scope it falls under, sub-types covered, and data entry options where applicable. Use the cluster index below to find the activity you are measuring, then apply the matching factors in Compare Your Footprint.
