DeCarbonPro

DeCarbonPro calculates and records embedded emissions for goods covered by the EU Carbon Border Adjustment Mechanism. Operators outside the EU map their installation, its production routes and its precursors once. The platform derives embedded emissions per good from that data, keeps the evidence you attach with the figures it supports, and produces the emissions data the EU buyer asks for. EU declarants and their representatives collect those figures against their own imports, compare suppliers, and see what a consignment will cost in CBAM certificates before it is declared. A producer's embedded emissions are calculated with the equations of Implementing Regulation (EU) 2025/2547, and the published acts are checked daily for changes. A set of free tools is open on decarbonpro.com with no account: a CN-code lookup, a sector cost calculator, de minimis and exemption checks, the extra cost of using default values, and the price of CBAM certificates.
