Ping An Insurance (Group) Co. of China Ltd. on Monday unveiled a rating system aimed at boosting environmental, social and governance investing in China's capital markets.

The Chinese insurance giant, which also has sizable banking, asset-management and financial-technology arms, said its CN-ESG Smart Rating System provides a suite of ESG investment tools with comprehensive, intelligent and practical features that are China-specific.

Ping An said that while corporate ESG information disclosure has increased over recent years in China, the scope and quality of such disclosure still lags levels found in other major capital markets.

Ping An said its CN-ESG system can help companies to better understand and improve their ESG performance and disclosure standards while also helping to eliminate ESG-related risks.
