Discover the Open Carbon API™ directory

Responsible purchasing is a powerful tool in the low-carbon transition, but relying on ESG rating can be complex and opaque, and can sometimes even lead to greenwashing. This is why we are launching the first carbon scoring API for companies. The carbon performance of companies will be re-evaluated each year by our experts on the basis of the most up to date available data. To empower consumers, shareholders and investors, to make more enlightened decisions we have developed the carbon scoring API platform which lists the Carbon Score of companies - a bit like the Nutriscore which allows us to know the nutritional quality of a food.
