Our method

Understand the data behind your procurement decisions.

Emission factors from published and openly licensed data, calculated in line with the GHG Protocol and ISO 14040 and 14044.

From source to assessment

How we build and explain the assessment.

Published and openly licensed data
We combine published and openly licensed emission-factor data with context such as material type, geography, life-cycle stage and relevant physical emission drivers. Coverage and suitability depend on the material and use case.
Calculation aligned to the GHG Protocol
Understand the approach used for your assessment, including relevant GHG Protocol alignment and assessment boundaries.
Traceable sources
Review the source behind the data and the assumptions used in the calculation. Assess whether the data fits your intended use.
Clearly labelled estimates
Understand where a result is estimated rather than measured. Review the assumptions and revisit estimates as data improves.

Why trust us

Climate scientists, not a support queue
Our climate and data scientists work through your data with you directly. You can talk to the people who built the model, by name.
We publish how it works
How we calculate is written down and open to scrutiny. If you want to challenge how we got to a number, there is a document to argue with.
We tell you what we do not know
Confidence scores on every estimated figure. You see the weak spots on screen rather than discovering them in an audit.
The 70% nobody can give you
Suppliers can reliably provide about a third of your Scope 3 data. We estimate the rest transparently rather than pretending the gap will close on its own.
