Try out the Trip to Carbon API
An embeddable carbon calculator for your website.Coming Soon
There are plans to make the core functionality
of trip to carbon open source soon.
Current Objective: developing API wrappers for different languages.
If this is something you may be interested in then join the discord :)
The API uses two methods outlined by the IPCC, DEFRA U.K & GHG Protocol. https://www.notion.so/Trip-to-Carbon-Calculations-Info-e8d5e1bf80d647f09bfce784c19a5423
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 API is free to use at the current rate limits. Trip to Carbon will soon have a new open model that allows people to self-host the API and other tools (thus, you decide the limit). Sign up to the newsletter to be updated when this is launched!
The API can be used for a range of things. Examples: Calculating personal/business emissions or Integrating into travel sites

Trip to Carbon's API cannot be accessed from client side scripts. To get around this we suggest using a proxy server to make requests to the API from you client side script/application
