Welcome to our public API!

You can get all the possible conversions at carbon.to/all

Once you decide in which unit to convert, output is available in JSON and XML, for instance carbon.to/beers. For specifying JSON as output call carbon.to/beers.json

Use the parameter ?co2=amount for specifying the amount of CO2 to be converted: carbon.to/beers?co2=200

Enjoy!
