- Automated spend-to-emissions categorisation
- Simple integration, comprehensive documentation
Building Carbon Features Should Not Mean Building Carbon Infrastructure
If you are building a platform that needs carbon data, you face a choice: spend months building emission factor databases, categorisation logic and calculation engines from scratch, or use an API that handles it all.
Maintaining emission factor databases is a full-time job. Factors change annually, new sources are published, and different regions use different methodologies. Getting the categorisation right requires domain expertise that most development teams do not have.
The EcoHedge API gives developers access to production-ready carbon accounting infrastructure. Focus on building your product while we handle the emission factors, categorisation and calculations.

What Our Customers Say
"The API documentation is excellent. We had carbon data flowing through our platform within a day."
"Building our own emission factor database would have taken months. The EcoHedge API saved us enormous time and effort."
"The categorisation API is remarkably consistent. It handles edge cases that we expected to need manual review."
