A carbon-footprint table produced at year-end does little for financing. SNSUC's approach is to write each lot's carbon-intensity factor as a field in the digital warehouse receipt, anchored on-chain with SHA-256 alongside the bill of lading number, inspection certificate and loading-port voyage. Where the cargo is and how much carbon it carries become visible to the bank on the chain, without waiting for corporate self-reporting.

That gives green credit a pricing anchor. Previously a bank pricing a receipt-backed loan looked only at cargo value and liquidity; now the same receipt, if its carbon factor is low, can earn a lower spread - effectively moving the carbon cost from the refiner's books to a financing-side discount, a self-reinforcing incentive structure.

Operationally, the DCS+ platform pulls the loading-port carbon factor at receipt issuance and writes it into the receipt metadata. The bank's credit system reads the on-chain field and releases funds at a preset per-tonne-carbon discount rate. No new paper documents are added; settlement is T+0 and shares the risk controls of the existing receipt-pledging channel.
