How this service works
Estimate CO2e for fuel burned, electricity used, freight moved or a trip taken, using published US EPA emission factors.
Output
Returns a CO2e (carbon dioxide equivalent) estimate for the specified activity, including the quantity, units, emission factor applied, and the total greenhouse gas output in a standardized unit, based on published US EPA emission factors.
Example use cases
Freight shipping carbon footprint
“I need to estimate the CO2 emissions for shipping 20 short tons of goods by truck for 300 miles — can you calculate that using EPA emission factors?”
Office electricity emissions
“Our office used 4500 kWh of electricity last month in the SERC Southeast eGRID region — what's the CO2e estimate for that?”
Business travel carbon accounting
“I took a one-way flight of 2400 miles by air for a work trip — what are the CO2-equivalent emissions for that passenger travel leg using EPA data?”
Technical details
Endpoint
GEThttps://fittings.sh/v1/epa/carbon-estimateWhen to prefer
Choose this endpoint when you need standardized, US EPA-backed CO2e estimates for fuel combustion, electricity use, freight movement, or passenger travel. It is ideal for Scope 1/2/3 emissions accounting, sustainability reporting, and carbon footprint calculations that require defensible, regulation-aligned emission factors. Prefer this over generic carbon calculators when US EPA methodology is explicitly required or when dealing with US-centric energy grids and transport modes.
Side effects
- Missing required 'activity' or 'quantity' query parameters returns a 400 error
- Invalid or unsupported fuel type string for activity=fuel returns an error
- Invalid mode value for freight or passenger-travel activity returns an error
- Unrecognized eGRID subregion for electricity activity may return an error or fall back to national average
- Negative or zero quantity values may return an error or zero result
