ESG Report 2025

Energy management has been embedded into daily operations through the dual drivers of performance assessment and metering-based monitoring. Workshops apply unit quota management to key energy consumption categories such as water, electricity and steam, and conduct monthly statistical analysis. Assessment results are directly linked to monthly and annual performance bonuses: where actual unit consumption outperforms targets, proportional rewards are granted; where consumption is worse than target, corresponding deductions are made. At the same time, metering instruments are installed across the power distribution system, major energy-using equipment and energy entry points, enabling hierarchical and itemised real-time monitoring of energy consumption and supporting precise scheduling and continuous optimisation. Through ongoing technical renovation and refined management, the Company steadily improved its energy efficiency in 2025. A number of energy-saving retrofit projects covering waste heat recovery, frequency conversion upgrades and process optimisation were completed and put into operation. During the Year, these projects delivered annual electricity savings of 14.25 million kWh, steam savings of 180,000 tonnes and natural gas savings of 9.17 million cubic metres, equivalent to approximately 29,700 tonnes of standard coal saved, with total investment of approximately RMB75.95 million.
