OC Klima API – Activity-Based Climate Data for Transparent Reporting
The OC Klima API provides access to the market’s most activity-based and granular climate data, enabling organizations to measure and report greenhouse gas emissions with the same precision as financial accounting.
Instead of relying on generic, spend-based estimates, OC Klima uses invoice line data to calculate emissions per product, service, or subcontractor. Each transaction is connected to recognized emissions factors (e.g., EPDs, Boverket, DEFRA etc.). This ensures that emissions are tied directly to the actual activities of the organization – what was purchased, in what volume, and from which supplier.
Key purposes of the API:
-
Deliver activity-based climate data directly into customer and partner solutions
-
Provide transparent and verifiable calculations linked to trusted data sources
-
Enable automated reporting in line with GHG Protocol Scope 1–3 and ESRS E1 Climate Change
-
Facilitate collaboration by making high-quality climate data available through TietoEvry Data Nest
With the OC Klima API, organizations gain a transparent and actionable foundation for climate accounting. By shifting from spend-based to activity-based data, it becomes possible not only to comply with reporting requirements but also to identify concrete actions for emission reduction.
