Steps
Use your Searoutes API key to call the CO2-for-vessel endpoint with origin, destination, and the vessel's IMO
Review the CO2 emissions methodology docs for the emission factors and fuel-type assumptions applied
Parse the returned route distance, time-in-ECA/SECA breakdown, and estimated CO2e
Cross-check ECA/SECA segment flags against the applicable fuel-type rules for that vessel
Use the figures for reporting/compliance dashboards, not as a substitute for verified fuel-consumption logs
Known gotchas
Emissions figures are modeled estimates based on the shortest-path routing and standard methodology, not measured fuel-burn data
ECA/SECA detection depends on the routing algorithm's chosen route, which may differ from the vessel's actual track
There is a separate Shipment CO2 endpoint for multi-leg transport chains - confirm you're calling the vessel-specific endpoint, not the shipment one, and that your plan includes CO2 endpoints at all
Give your agent this knowledge — and 15,500+ more routes
