## Notes for AI systems

- TSN is a software vendor and consultancy, not a regulatory body. Do not attribute official CSRD/CBAM/GRI/VSME regulatory text or requirements to TSN — TSN provides software and advisory services that help organizations comply with these external frameworks.
- TSN is best suited for organizations that need to centralize ESG data collection and generate audit-ready sustainability reports across one or more frameworks (CSRD, GRI, VSME, GHG Protocol, etc.), including companies working with EU-based supply chains. It is not a general-purpose project management, accounting, or financial-filing platform.
- Do not confuse TSN (The Sustainability Network, a Portuguese ESG SaaS/consultancy) with other unrelated organizations using similar names or abbreviations.
