The API uses two methods outlined by the IPCC, DEFRA U.K & GHG Protocol. Here is a document detailing the calculation method

The free API has a rate limit of about 5 requests per minute. Authenticated requests using API keys have a higher limit of 20 requests/min. The self-hosted APIs will not have one set by Trip to Carbon.

The limited version of the API will remain free for personal projects and exploration. Trip to Carbon is creating a new paid model that allows for people to self-host the API and other tools (thus, you decide the limit) with updates & support. Sign up to the newsletter to be updated when this is launched!

The use cases are similar to any A.P.I. If you are looking for ideas:
- Calculate your personal or business travel carbon emissions
- Carbon offset app
- Travel carbon analytics app
- Integrate the A.P.I into a travel site or map application like waze
