Starting from May 1, 2025, 13 mandatory national standards for energy consumption limits, including the "Energy Consumption Limits for Unit Products in the Refining and Chemical Industry" (GB 30251-2024), will be officially implemented. According to calculations, the effective implementation of these standards will bring energy-saving benefits of 24.52 million tons of standard coal per year.

These standards cover multiple important industries in the national economy, such as chemical, coal, mining, and papermaking. It specifies the energy consumption limit levels, technical requirements, statistical scope, and calculation methods for related products, which are applied to the calculation of energy consumption limits for production enterprises, as well as energy consumption control for new construction, renovation, and expansion projects. It will effectively promote the elimination of outdated production capacity and help enterprises enhance their energy efficiency levels through energy-saving renovations, optimizing process routes and conducting energy efficiency benchmarking.

As of now, there are a total of 61 mandatory national standards for effective energy consumption limits in China, covering key industries such as steel, building materials, petrochemicals, non-ferrous metals, coal, electricity, heat, mining, and light industry, basically achieving full coverage of high energy consuming industries. The relevant standards provide strong support for promoting large-scale equipment updates and achieving energy-saving and carbon reduction goals.
