On March 2, 2026, China's Ministry of Ecology and Environment launched the second edition of the National Greenhouse Gas Emission Factors Database, covering 52 industries including power, heat, cement, and electrolytic aluminum. Verified by UNFCCC third-party auditors, this database has become a critical reference for Chinese exporters preparing Environmental Product Declarations (EPDs), complying with the EU Carbon Border Adjustment Mechanism (CBAM), and negotiating green procurement contracts.

Event Overview

The updated database provides standardized emission factors for 52 key industries, with data undergoing rigorous third-party verification under UNFCCC standards. Notably, European and American buyers have begun incorporating database citation rates into supplier ESG evaluations, making adoption crucial for maintaining export competitiveness.

Impact on Key Industries

Export-Oriented Manufacturing

Electrolytic aluminum and cement producers face immediate pressure as CBAM-covered sectors. The database's figures will directly determine carbon tariff calculations for EU-bound exports, with discrepancies potentially triggering audits.

Supply Chain Operators

Upstream suppliers to export industries must align emission calculations with the new factors. Major buyers are requiring Tier 2-3 suppliers to reference the database for Scope 3 emissions reporting.

EPD Certification Services

Consulting firms providing carbon accounting services need to update calculation models. Non-compliant reports using outdated factors may face rejection by EU authorities.

Action Points for Enterprises

Priority Verification

Exporters should cross-check existing carbon data against the database, particularly for CBAM-covered goods like steel and aluminum where discrepancies exceed 5% in pilot tests.

Documentation Upgrade

Procurement teams must update supplier questionnaires to explicitly request database-compliant emissions data, now a baseline requirement for ESG-conscious buyers.

Capacity Building

Technical staff require training on database application methodologies, especially for combined heat-power systems where allocation factors changed significantly.

Industry Perspective

From an industry standpoint, this update signals China's standardized carbon accounting system reaching international parity. The database's UNFCCC endorsement gives it unique weight in trade contexts, though some sectors may face transitional challenges in methodology alignment. Most critically, it represents a shift from voluntary to mandatory carbon data standards for China-EU trade flows.

Conclusion

The database's release establishes a definitive benchmark for corporate carbon accounting in China's export economy. While immediate compliance is essential for CBAM preparedness, enterprises should view this as the foundation for evolving ESG reporting requirements across global supply chains.
