1.1 Framework system

Datayes’s ESG data framework system is in the form of a three-tier framework: it contains three major dimensions, 15+ primary topics, 60+ secondary topics, and eventually refined to 700+ standardized indicators. Among them, environmental issues mainly cover pollution prevention and control, resource consumption, environmental management, etc.; social issues include employee rights and interests, R&D innovation, social response, etc.; and corporate governance issues include governance structure, governance results, and governance institutions, etc.
