Direct sources. Structured data.
Every record in the database starts with a documented request to a port authority — and ends with a verified, source-attributed entry.
Reach out
Structured requests sent to port authorities in their official language and protocol. Each request follows the channel the authority recognises — port authority office, harbour master, environmental department.
Verify
Each response is classified by completeness, cross-checked against the relevant convention text, and reviewed for contradictions with other authoritative sources.
Structure
Verified data lands in a port-by-port database with full source attribution.
Categories under active mapping.
The system focuses on the discharge and emission categories most often subject to local variation. Coverage expands as port authority responses are received and verified.
