— Approach

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.

Step 01

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.

Step 02

Verify

Each response is classified by completeness, cross-checked against the relevant convention text, and reviewed for contradictions with other authoritative sources.

Step 03

Structure

Verified data lands in a port-by-port database with full source attribution.

— Scope

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.
