Prasine Index checks the climate claims of large European companies against public records: verified emissions in the EU Emissions Trading System, enforcement records on environmental marketing, climate target registries, lobbying assessments and open climate datasets. Each assessment is published with its evidence and sources, and the code is open source.
In November 2026 every published assessment was reviewed against its sources. Since then, each enforcement record in the pipeline has been checked twice against its official source and now carries a verbatim quotation. The scoring is being redesigned so that a score can be traced to the records behind it.
Three assessments were withdrawn after the review, and the corrections page explains why. The five below are under revision.
These five assessments were made with the version 1 method. Each report sets out the claims, the evidence and its sources.
Each report is under revision and will be reassessed with version 2.
