Wind turbines in landscape – Our API solution supports sustainable development

API description

OpenCO2net offers a web API through which emission factor data can be obtained using HTTP request (see picture). The OpenCO2 API uses API-key authentication and authorization.

The OpenCO2net API brings emission factors easily into your company's own systems.

Emission factors are requested through the API by emission factor classes:

  • Car
  • Waste
  • Public transport
  • Greenhouse gases
  • District cooling
  • District heating
  • Flights
  • Service
  • Fuel
  • Buildings
  • Food and drink
  • Electricity
  • Electric device
  • Freight traffic
  • Industrial steam
  • Product
  • Machinery and equipment
  • Equity investment


In special cases, emission factors can be requested separately. A desired unit of emission factors can be added to the request in order to streamline the calculation. Subscriptions are sold for the interface and are priced based on the number of emission factor categories. See pricing.

OpenCO2net Oy is the most reliable partner in emissions accounting.
