Carbon Interface

Carbon Interface gives developers the ability to add carbon emissions estimates to their applications through an easy to use API. Carbon Interface currently supports four different emission estimate types:

1. Passenger flights
2. Freight shipments (ocean containership, diesel train, diesel truck, and plane)
3. Electricity generation in Canada and the U.S.
4. Vehicle emissions data on 10,000+ vehicles
5. Static fuel combustion with 13 different fuel sources

Carbon Interface offers a free plan for a low number of monthly requests and paid plans for larger applications.
