API description

OpenCO2.net 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.

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.
