CBAM Precursor-Emissions Aggregator

Rolls up embedded emissions across precursors in a steel/aluminium value chain (including the 2028 pre-consumer-scrap rule) so a producer can supply verifiable complex-goods emissions to its importer. Pre-positions the downstream-180 scope extension (Council position 12 Jun 2026, application 1 Jan 2028). Part of the cbam-precursor chain.
