Who we serve
We certify European portfolios of 10 to 500+ assets, end to end, for the institutional owners who run them.
Execute the mandate and prove investments are green
For asset and fund managers who need defensible, traceable evidence behind every green claim, so LP and regulatory reporting holds up to scrutiny while certification cost and effort come down.
Turn certification into value
For listed and non-listed owners protecting asset value, with a clear, costed sustainability plan they can execute asset by asset.
How it works
From raw evidence to a certified portfolio, in five steps.
Drop in every document at once
Bulk upload plans, reports, certificates and invoices. The AI classifies each file and maps it to the credits it supports.
Evidence intake
Auto-classified and mapped to credits
The agent assesses every credit
Each credit is scored against the evidence you hold, with gaps flagged before they cost you a rating.

AI drafts, our assessors verify
The agent writes submission-ready answers traced to the exact document and page. A qualified Sustainix assessor then reviews every answer and confirms it during the on-site audit visit, so nothing reaches the certifier unchecked.
