On March 2, 2026, China's Ministry of Ecology and Environment launched the second edition of the National Greenhouse Gas Emission Factors Database, covering 57 categories of export-oriented products including electricity, aluminum, cement, and photovoltaic glass. The database provides region-specific and equipment-type-specific emission factors with an accuracy of ±3.2%. Recognized by the GHG Protocol as a 'Recommended China Benchmark,' this development significantly impacts industries involved in international trade, particularly those exporting to markets with strict carbon regulations like the EU, US, and Japan.

Event Overview

The updated database offers precise emission factors for key export products, enabling more accurate carbon footprint calculations. It has gained international recognition, being listed by GHG Protocol as a reference standard for Chinese products. This means carbon reports using these factors will be directly accepted by EU's CBAM, US SEC climate disclosure rules, and Japan's green procurement list.

Impact on Specific Industries

Export-Oriented Manufacturers

Companies producing aluminum, cement, and photovoltaic products will benefit from reduced verification costs when exporting to regulated markets. The database's recognition eliminates the need for additional third-party validation in many cases.

Supply Chain Managers

Businesses managing international supply chains can now access standardized emission data for Chinese components, simplifying carbon accounting across production networks.

Carbon Accounting Service Providers

The standardized database may shift demand from verification services to implementation support, as the core emission factors are now government-provided.

Key Considerations for Businesses

Update Carbon Accounting Systems

Companies should immediately integrate these official emission factors into their carbon accounting processes to ensure compliance with international standards.

Review Product Categories

Pay special attention to the 57 covered product types, as these now have pre-approved emission data for key export markets.

Monitor Implementation Timelines

While recognized, the actual adoption timelines may vary across different regulations and markets.

Industry Perspective

From an industry viewpoint, this represents more than just updated data - it signals China's commitment to standardized environmental reporting. The database's international recognition suggests it may become the default reference for Chinese products in global carbon markets. However, businesses should view this as an evolving standard rather than a final solution, as methodologies may continue to develop.

Conclusion

The release of China's updated emission factors database establishes an authoritative reference point for carbon accounting of Chinese exports. While it simplifies compliance for many businesses, companies should treat this as the beginning of more standardized reporting rather than a complete solution. The database's international recognition positions it as a key tool for navigating increasingly complex carbon regulations.
