China Galaxy Securities research report stated that the Ministry of Ecology and Environment and 15 other departments jointly issued the Implementation Plan for Establishing a Carbon Footprint Management System, which requires the initial establishment of a carbon footprint management system by 2027. It is recommended to explore investment opportunities from two dimensions: green electricity and energy-saving and carbon reduction. Green electricity: Energy is the main source of carbon, and using new energy is the most direct and effective way to reduce carbon emissions. With the increasingly perfect carbon market, the demand for green electricity is expected to experience explosive growth, and the premium of green electricity is also expected to increase significantly. Energy-saving and carbon reduction: On the one hand, the clean development trend of high-energy-consuming industries such as thermal power, heating, steel, and cement is clear. The transformation of existing production capacity and the strict emission standards of incremental production capacity are expected to promote the optimization of the industry competition pattern, and will also drive the demand for equipment and technology related to low-carbon transformation; On the other hand, carbon emission data are the foundation for building a carbon footprint management system, so equipment and software related to carbon emission measurement and monitoring are facing development opportunities. Recommended individual stocks to pay attention to: power sector Huaneng Power International, Huadian Power International, etc.; energy-saving and environmental protection sector Beijing GeoEnviron Engineering & Technology, Zhejiang Weiming Environment Protection, etc.
