How this service works
Shipment carbon estimate from cargo mass, distance and mode (air, road, rail, sea) in kg CO2e
Output
A JSON object containing the input echo (weight_kg, distance_km, mode), computed tonne-km, the emission factor (kg CO2e per tonne-km), estimated CO2e in both grams and kilograms, the formula used for the calculation, a rounding rule note, a scope note explaining what is and isn't covered, and a source note citing the underlying emission factors.
Example use cases
E-commerce shipment carbon labeling
“Calculate the CO2e emissions for shipping a 12 kg package by air freight over 6500 km — I want to show the carbon footprint on our checkout page.”
Supply chain sustainability reporting
“We're shipping 50000 kg of goods by sea across 18000 km and 8000 kg by road for the last 200 km — can you estimate the kg CO2e for the sea leg so I can include it in our annual sustainability report?”
Freight mode comparison for logistics planning
“I need to compare the carbon footprint of sending 3000 kg of freight 4500 km by air versus rail — estimate the CO2e for the rail option so I can weigh the trade-offs.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/shipping/carbon?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, per-shipment carbon emission estimate based on standard emission factors for a known transport mode, weight, and distance. It is ideal for carbon labeling, sustainability reporting, or logistics mode comparison where a science-based formula and source citation are needed. It is not suited for multi-leg journey aggregation in a single call, real-time carrier-specific tracking data, or scope 1/2/3 full lifecycle analysis.
Side effects
- Missing required query parameters (weight_kg, distance_km, or mode) returns an error
- Invalid mode value (not one of air, road, rail, sea) returns a validation error
- weight_kg or distance_km outside allowed ranges (weight <0.001 or >100,000,000 kg; distance <0.1 or >1,000,000 km) returns a range error
- Non-numeric values for weight_kg or distance_km cause a parsing error
- Payment not provided or insufficient (x402 protocol) results in a 402 Payment Required response
