On August 14, 2020, China Resources Power was selected for the first time as a constituent stock of the Hang Seng ESG50 Index and a benchmark index for sustainable development companies.

The selection of the Hang Seng ESG50 Index and the Sustainability Index targeted at the sustainability performance of listed companies in Hong Kong aims to provide a benchmark for investors who are concerned about environmental and social responsibilities. By commissioning the Hong Kong Quality Assurance Agency (HKQAA) as an independent third party to measure companies' performances in corporate governance, human rights, labor practices, environment, fair operation practices, consumer issues, community participation, and development, the Hang Seng Index Company finally selects the most outstanding enterprises embracing sustainable development as the index.
