Sylvera: sovereignty score and 8 European alternatives

Sylvera is a carbon data platform that rates carbon credits and projects and provides market intelligence for carbon markets. Its offering includes ratings, market intelligence, an Article 6 and CORSIA hub, and analysis of carbon-related commodities. Project developers, buyers, investors, governments and registries use the platform, which is delivered through Sylvera's web platform.

Sylvera Ltd is registered in London, United Kingdom, and the company launched in the UK in 2020. The website does not describe a parent company or majority shareholder. According to its privacy notice, hosting and data services are provided among others by Amazon Web Services and Supabase, with locations in the European Union and the United States; Webflow and Snowflake are also US providers. For a European organisation this means US sub-processors in the chain, which matters for transfer assessments under the GDPR.

Why digital sovereignty matters with Sylvera

Sylvera is headquartered in GB, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

Sylvera hosts data in EU, US. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

Sylvera 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 Sylvera together with your other vendors and gives a total score, a heatmap and the main risk drivers.
