Which Scope 3 Categories Actually Matter for Your Business
Of the fifteen Scope 3 categories the GHG Protocol defines, usually only two to four are genuinely material for a given business, most commonly purchased goods and services, transport and distribution, and use of sold products depending on the specific product. Most companies waste significant effort trying to measure categories that turn out not to matter much for their specific business once properly screened.
Why chasing all fifteen categories equally is a mistake
Data-collection effort spread evenly across fifteen categories means precision everywhere and depth nowhere, including in the one or two categories that might represent 80% of total emissions. Screening first concentrates effort where it actually changes the total picture.
How to run a quick category screening
Use rough, spend-based estimates across all fifteen categories first, purely to identify which ones are large enough to matter. This first pass doesn't need to be precise, it needs to correctly identify the two to four categories worth investing real measurement effort into.
Why the answer differs so much by industry
A manufacturer's material categories usually centre on purchased goods and use of sold products; a services firm's often centre on business travel and purchased services instead. There is no universal answer, the screening step exists specifically because the material categories genuinely differ by business model.

We find the Scope 3 categories that actually matter for your business, move you from spend-based estimates to supplier-specific data, and embed the result in procurement decisions.
