get https://api.searoutes.com/co2/v2/execution/
This endpoint returns the CO2 details of an itinerary by hash (the unique fingerprint used to identify an itinerary). Those hashes are returned in /itinerary/v2/execution.
The response gives the CO2e breakdown at the itinerary level (total, wtt, ttw, intensity), as well as at the leg level.
The distances are given in meters and the CO2e emissions in grams per TEU.
