The calculator combines cargo weight, distance travelled, transport mode, and vessel or vehicle type into a single emissions estimate. Enter a route and cargo details, or pick a carrier, and it returns the CO2 figure for that specific shipment.

Calculate CO2 emissions for any shipment
Enter a route or pick a carrier and get an emissions estimate across sea, air, and road — built on recognized industry standards, not a rough guess.
Two Ways to Calculate
Start from a route, or start from a carrier
By route
Enter the origin and destination and choose the transport mode and cargo type — container, bulk, or RoRo. The calculator accounts for the specifics of each to return an accurate CO2 estimate for that exact shipment.
By carrier
Pick a shipping line to see its historical emissions performance on a given route. Useful when the choice of carrier — not just the route — is what's driving the footprint of a shipment.
Built On Standards
Compliant by design, not as an afterthought
The calculator is built on the Global Logistics Emissions Council (GLEC) Framework and ISO 14083, so the numbers you get are ones you can put in a report or hand to an auditor. A few inputs get you an automated, standards-based estimate — no spreadsheets, no separate consultant.
Why It Helps
One tool, every transport mode
-
Emissions per kilometre
See the carbon cost of any route worldwide in a few clicks, no separate report required.
-
Sea, air, and road covered
One calculator for every mode, instead of switching tools depending on how the cargo moves.
-
Compare before you book
Line up routes and carriers side by side to see which option actually costs the least in CO2.
-
Numbers you can report
GLEC- and ISO 14083-aligned figures, ready for ESG reporting or a client-facing sustainability claim.
Built For
Different teams, same numbers
-
Freight forwarders
Give clients an emissions figure alongside the quote, not as a follow-up email.
-
Importers & exporters
Check the footprint of a shipment before choosing a carrier or route.
-
ESG & sustainability teams
Pull standards-based figures for reporting without chasing data from ops.

FAQ
Got any questions?
Calculations follow the Global Logistics Emissions Council (GLEC) Framework and ISO 14083, the two reference standards for logistics emissions accounting — so the output is usable in formal reporting, not just a rough internal estimate.
Yes. The calculator covers sea, air, and road, so a multimodal shipment can be estimated leg by leg instead of guessing at the non-ocean portions.
Yes — search by carrier to see its historical emissions performance on a given route, so the carrier itself can factor into a routing decision, not just price and transit time.
Yes — the Carbon Emissions API returns the same standards-based figures shown here, built for CRM, TMS, and ERP integration.
