The notation, named ‘a‑EA (CFP)’, indicates that the carbon footprint generated during a vessel’s construction has been assessed and undergone third-party verification by ClassNK, enabling the use of process-specific data instead of general emission factors. Prescribed in ClassNK’s ‘Environmental Guidelines (Edition 4.2)’, the framework allows shipyards to externally demonstrate the use of low-carbon materials and emission-reduction measures, and provides shipowners with verified data to support more accurate Scope 3 (Category 2, capital goods) emissions disclosure.
