Carbon Footprint of Freight and Shipping API

Carbon Footprint of Freight and Shipping API

The freight/shipping emission estimations are for Road, Rail, Air and Sea (categorized into Short Sea and Deep Sea). Recommended average emission factors and guidelines have been used as proposed by member companies of ECTA (European Chemical Transport Association) and Cefic which are aligned with CN's recommendations. Two additional calculations for Intermodal shipping are available: 1) Road with Rail and 2) Road with Short Sea. In both cases, the road distance is assumed to be 10% of the entire journey.

CarbonSutra API calculates the carbon emission footprint for your organization. Hosted at ZYLA, it can be instantly tested by yourself at no cost.

This particular API is used to calculate the footprint associated with freight shipment. It estimates the carbon emissions for road, rail, air and sea. If the shipment is for maritime transport of goods on intercontinental routes and crossing oceans, select deep sea. However, for relatively shorter distances, select short sea. Lastly, there are two additional calculations for Intermodal shipping. The first is combination of Road with Rail and second, Road with Short Sea. The final emission is calculated based on weight of freight and length of journey. The API then returns the value of carbon dioxide equivalent in kilograms, metric tonnes and pounds.


API Documentation


The following fields are ingested:

TRANSPORT_MODE : Mandatory. The values for mode of transport are listed here. Deep sea (value: DeepSea) shipping refers to the maritime transport of goods on intercontinental routes, crossing oceans as opposed to short sea (value: ShortSea) shipping over relatively short distances.​ For Intermodal shipping of 1) Road with Rail and 2) Road with Short Sea, the road distance is assumed to be 10% of the entire journey. The permissible values are:

FREIGHT_WEIGHT : Mandatory. The weight of freight in kilograms (KG). If an undefined value is passed, it will be set to 1.00

DISTANCE_VALUE : Mandatory. The distance of journey in kilometers (KM). If an undefined value is passed, it will be set to 1.00

Prices are based on a recurring monthly subscription depending on the plan selected β€” plus overage fees applied when a developer exceeds a plan’s quota limits. In this example, you'll see the base plan amount as well as a quota limit of API requests. Be sure to notice the overage fee because you will be charged for each additional request.
