What's in it

Data offered docs-verified
electricity emissions calculation · travel emissions calculation (car, plane, train) · freight emissions calculation · procurement spend-based emissions calculation · hotel stay emissions calculation · cloud computing emissions calculation · travel spend emissions calculation · emission factor search · custom emission factor calculation
Coverage llm-inferred
Global
Formats llm-inferred
MCP stdio
Access docs-verified
Requires a Climatiq API key (CLIMATIQ_API_KEY); MIT licence; sign-up at app.climatiq.io; pricing not stated in docs

Useful for

Use cases llm-inferred
Scope 2 electricity emissions for a site or office energy use in a consultancy carbon report · Freight emissions for materials delivery to a civils or drainage construction site · Staff travel emissions for an environmental consultancy's annual carbon footprint · Procurement-based emissions estimate for a bill of quantities using spend data
Audience llm-inferred
sustainability consultants · environmental consultants · civils engineers · carbon accountants · planners preparing climate impact statements

Limitations

Constraints llm-inferred
Requires a Climatiq API key before any calculation works · Docs do not state which emission factor dataset, year or UK-specific factors are used · Docs do not state rate limits, pricing or quotas · Region selection is shown only as a parameter in the CLI example (e.g. US), so UK coverage is not confirmed · Metadata lists no tools, so the tool list is taken from the docs · Docs do not state the output format or data schema of calculation results

Example tool calls docs-verified

Estimate Scope 2 emissions for 1,000 kWh of site electricity, using a UK region code (argument names inferred from the docs' CLI example, not confirmed against the tool schema)

{
  "tool": "electricity-emission",
  "arguments": {
    "energy": 1000,
    "unit": "kWh",
    "region": "GB"
  }
}

Find candidate emission factors for freight transport before running a custom calculation (argument name is inferred, not confirmed)

{
  "tool": "search-emission-factors",
  "arguments": {
    "query": "diesel HGV freight"
  }
