Key Features:

AI-powered expense categorisation: CarbonAPI Expense Categorisation takes unstructured accounting data, categorises it into one of 600 emission categories, and selects an appropriate emission factor, calculating emissions quickly and accurately.
Automatic FX & inflation calculations: If your expenses and our factors are in different currencies, we'll handle the FX calculations for you, as well as adjusting for inflation automatically using World Bank figures.
Global supplier dataset: On top of our commodity dataset, we licence modelled supplier-specific factors for over 10,000 leading brands worldwide from Roundarc, allowing you to move past generic averages.
