CO2 AI: sovereignty score and 8 European alternatives

CO2 AI is a sustainability platform that enterprises use to measure, track and report their emissions, including across supply chains, with the aim of reducing them. The software is aimed at large organisations that have to meet corporate reporting requirements, and it is delivered as a software platform for corporate sustainability and finance teams. The product was first developed inside Boston Consulting Group (BCG) and became an independent company in September 2023, with BCG remaining a strategic partner.

The company is headquartered in Paris, France, and has operations in Germany, the Netherlands, Spain and the United States. Its investors include the venture firms Unusual Ventures and Partech, along with BCG, and no majority owner is named. As an EU-headquartered provider it is subject to EU data protection law. Public information on hosting locations is limited, so organisations should request a data-location statement and a data processing agreement before sending emissions data.

Why digital sovereignty matters with CO2 AI

CO2 AI is headquartered in FR and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so CO2 AI scores best on data residency.

CO2 AI is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs CO2 AI together with your other vendors and gives a total score, a heatmap and the main risk drivers.
