# UK Grid Carbon Intensity Emission Factors by Fuel Type

> UK Grid Carbon Intensity Emission Factors by Fuel Type is a paid API for AI agents from clonecho.builda.company, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Returns carbon intensity emission factors (gCO2/kWh) for each fuel type used in the Great Britain electricity grid.

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 uk-grid-carbon-intensity-emission-factors-by-fuel-type-758cb273 -d '<json body>'
```

Example prompt: What are the carbon intensity emission factors in gCO2/kWh for each fuel type on the GB electricity grid right now?

## When to prefer this

Use this endpoint when you need static or reference-level carbon emission factors per fuel type for the GB grid — ideal for sustainability calculations, carbon accounting, or enriching energy data with emissions context. Prefer over the half-hourly national forecast endpoint when you need per-fuel-type granularity rather than time-series aggregate intensity.

## Known failure modes

- Service unavailable returns HTTP 5xx
- Unexpected JSON structure if upstream data source changes
- Stale data if the underlying carbon intensity dataset is not refreshed
- Payment failure for x402 protocol returns 402 with payment details

## How this service works

Carbon intensity emission factors (gCO2/kWh) per fuel type for the GB grid (no params). Returns JSON.

## Output

A JSON object mapping each GB grid fuel type (e.g. gas, coal, nuclear, wind, solar, hydro, biomass, imports) to its carbon intensity emission factor expressed in gCO2/kWh.
