Carbon Decision AI Methodology: Which Emission Factor Databases Do We Use?
From ADEME to the GHG Protocol, IEA, and IPCC: the complete map of the frameworks powering our CO2 calculations.
To calculate a company's carbon footprint reliably, the choice of data sources is everything. At Carbon Decision AI, precision is our baseline. That's why our calculation engine is primarily powered by the French ADEME database, supplemented by leading global frameworks to cover every aspect of your international operations.
Mapping the standards and databases behind the platform
| Assessment Area | Framework & Standard | Emission Factor Source |
|---|---|---|
| Methodology Framework | GHG Protocol Corporate Standard (WRI, 2015) | The global golden standard used to structure Scope 1, 2, and 3 reporting. |
| Greenhouse Gases | IPCC AR5 (100-year horizon) | Official CO2eq conversion factors for methane (CH₄), nitrous oxide (N₂O), and HFCs. |
| Electricity | IEA Electricity 2024 + National Agencies | Up-to-date grid factors calculated country by country for consumed power. |
| Freight & Logistics | EN 16258 / GLEC Framework | Accurate calculation models using ton-kilometer ratios for every transport mode. |
| Cloud & IT | ADEME + Vendor Energy Reports | Advanced evaluation of IT infrastructure impact (based on EUR spend and vendor-specific data). |
| Materials & Products | ADEME (Product Catalogue) | Official Product Emission Factors derived directly from the ADEME Base Empreinte database. |
The transparency choice
By combining the ADEME database for inputs and IT with global standards like the GHG Protocol and IEA, Carbon Decision AI ensures your reports meet auditor requirements and CSRD regulation.
