# MyCO2 Suite Freight Carbon Calculator

> MyCO2 Suite Freight Carbon Calculator is a paid API for AI agents from api.myco2suite.io, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).

Calculates CO2e emissions for freight shipments by weight and distance across road, rail, sea, and air transport modes, supporting single-leg and multi-leg intermodal routes.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability myco2-suite-freight-carbon-calculator-feb3e189 -d '<json body>'
```

Example prompt: Calculate the CO2e emissions for a 20,000 kg intermodal shipment from Shanghai (CNSHA) to Hamburg (DEHAM) — sea leg from Shanghai to Rotterdam (NLRTM) then road leg from Rotterdam to Hamburg — and give me a per-leg breakdown.

## When to prefer this

Choose this endpoint when you need to calculate freight-specific CO2e emissions by physical activity (weight × distance) rather than spend-based estimates. It is ideal for logistics, supply chain Scope 3 reporting, carrier comparison, and intermodal route analysis where you have actual shipment data. Prefer it over the spend-based carbon endpoint when you know the actual cargo weight and route details.

## Known failure modes

- Unknown or ambiguous port/airport identifier — returns error if UN-LOCODE, IATA code, or place name cannot be resolved
- Missing required fields such as weight or transport mode — returns validation error
- Unsupported transport mode combination — error if an invalid mode is specified
- Zero or negative weight/distance values — input validation error
- Service unavailable or rate limit exceeded — HTTP 5xx or 429 response

## How this service works

Freight carbon: CO2e for road/rail/sea/air shipments by weight × distance, single-leg or multi-leg intermodal. Ports/airports by UN-LOCODE, IATA, name or lat/long.

## Output

Returns total CO2e emissions for the shipment (in kg or tonnes), broken down by transport leg if multi-leg, along with the distance used per leg, emission factors applied, and methodology/source references.
