The China Green Certificate Price Index is compiled from nationwide
green-certificate transaction prices, using the national average price for a
specified period as the base and standardized into a composite, nationwide
authoritative price index. It is designed to objectively reflect the
supply-demand balance and price trend in China’s green certificate market. The
index uses January 2025 as the base period; the initial release provides monthly
index values from January 2025 onward and the NEA will publish the index on a
regular monthly basis.
