The revised Guidelines, jointly issued by MEP and MIIT, took effect Oct 30, 2026. For the first time, Scope 3 emissions from fuel oil trading — including transport, warehousing, and handling — must be reported by exporters starting 2027.

Each intake mints a 256-bit fingerprint, signs locally and goes on-chain; bills and certificates bind by second hash, with ESG tags by category.

CBAM 2026 enters the charging phase covering six sectors with free allowances to zero by 2034; petrochem is not listed yet, but batch-level PCF with SHA-256 verifiable carbon data is already a buyer pre-clearance.

SNSUC digital warehouse receipts hash bills of lading, inspection and inbound notes into a unique SHA-256 fingerprint in the browser, with title transfer and ESG carbon-footprint data written to the same ledger. The three-day paper-document round trip now closes in ten minutes.

SNSUC launched rubber-specific carbon footprint modules on its DCS+ platform today, enabling LCA-based calculation and ISCC Plus-aligned verification for natural and butadiene rubber across Thailand, Malaysia, and China.

On Oct 26, 2026, SNSUC launched a dedicated rubber module on its DCS+ Carbon Platform, enabling automated LCA-based carbon accounting and blockchain-verified certification for natural rubber (CNY 19,700/t) and butadiene rubber (CNY 16,170/t) across origin, processing, logistics, and warehousing.

China issued the Trial Guidelines for Petroleum Product Carbon Footprint Accounting, pushing Scope 3 accounting from wellhead to ex-works to the production side. SNSUC's DCS+ platform has already been adapted to the guideline; refiners' carbon cost shifts from a year-end line item to a metered, disclosable, tradeable burden.

China’s MEE and four other ministries jointly issued the 'Trial Guidelines for Carbon Footprint Accounting of Petroleum Products', effective Nov 1, 2026. SNSUC’s DCS+ platform has upgraded its data models to support automated LCA-based carbon accounting and blockchain-verified certification for 12 product categories including fuel oil and bitumen.

SNSUC’s Carbon Data System (DCS+) launched its bitumen lifecycle carbon footprint module on Oct 24, covering extraction, refining, logistics, and paving—fully aligned with ISO 14067 standards.

On Oct 24, 2026, SNSUC launched dedicated carbon footprint modules for natural rubber (19700 CNY/t, +0.43%) and butadiene rubber (16170 CNY/t, +1.51%) on its DCS+ platform, delivering ISO 14067-compliant LCA data.

On Oct 21, 2026, SAC released the draft GB/T XXXXX-2026 ‘General Principles for Carbon Footprint Accounting of Petroleum Products’, defining ‘transfer of de facto control’ as the key liability trigger for transshipment trade — already supported by SNSUC’s digital warehouse receipt system.

The CBAM definitive period starts in 2026 with free allocation phased to zero by 2034, covering six sectors first. Petchem is not in the first batch, but a PCF pre-condition demands verifiable batch-level carbon data, making cross-chain receipt mutual recognition and SHA-256 proof the compliance base.

The European Commission released Phase III CBAM transitional rules on Oct 18, explicitly including petroleum coke and bitumen — key SNSUC commodities. SNSUC’s free, standards-aligned (ISO 14067/PAS 2050) carbon footprint calculator is now live.
