Lei Yao, deputy director of the Institute of Finance of the People's Bank of China, said at the parallel forum on "National 'Dual Carbon' Strategy and ESG" at the 2023 Financial Street Forum Annual Conference on November 9 that to reduce the cost of sustainable development information disclosure and improve efficiency, it is necessary to rely on the so-called second-party and third-party assessment mechanisms, set up institutional arrangements such as transition periods, and strengthen the empowerment of science and technology, and strengthen the digitalization, standardization and intelligence of sustainable disclosure. Lei Yao said that the so-called digitalization is to strengthen the construction of data infrastructure and improve the level of digitalization in Scope 3 carbon accounting, supply chain carbon footprint management, reporting and other aspects, and the so-called standardization is to further strengthen the construction of classification standards for green finance and transition finance, and embed the design and market pricing of various financial products. In addition, in the future, big data intelligent models can be developed in terms of complex scenario analysis and major financial impact assessment, so as to provide more accurate pricing tools for financial market participants.
