How this service works
Selects a published emissions factor by activity, region and source edition. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age. This is neither legal advice nor customs advice.
Output
Returns the matched emissions factor value, unit, GHG scope, source metadata (URL, title, publication date), time window, data age, derivation method disclosure, and a list of any fields that could not be populated (unavailable_fields). All values are sourced from a specified published dataset edition.
Example use cases
Corporate carbon footprint calculation
“I need the emissions factor for natural gas combustion in the UK, using the BEIS 2022 dataset — give me the factor value, unit, and scope so I can calculate our Scope 1 emissions for our annual sustainability report.”
Supply chain emissions estimation
“What's the published CO2 emissions factor for long-haul diesel freight in the EU? Pull it from the GLEC Framework 2022 source and tell me the unit and any fields that aren't available.”
Software ESG module data enrichment
“My app needs to enrich user activity records with GHG factors — can you look up the emissions factor for commercial air travel in the US using the EPA 2023 edition, including the derivation method and source citation?”
Technical details
Endpoint
POSThttps://klima.halowerk.com/v1/emission-factorWhen to prefer
Use this endpoint when you need a citable, source-backed greenhouse gas emissions factor tied to a specific published dataset edition and region — especially for compliance, ESG reporting, or carbon accounting workflows where auditability and source disclosure matter. Prefer this over generic carbon calculators when you need the raw factor value with provenance rather than a pre-computed emissions estimate.
Side effects
- Activity or region not found in the specified source edition — factor returned as null with unavailable_fields populated
- Invalid or malformed source URL causes request rejection
- Source edition date is outside supported range
- Region string is ambiguous and cannot be resolved to a known jurisdiction
- Factor array exceeds 10,000 item limit
- Missing required source fields (url, published_at, title) causes validation error
