Hindustan Zinc Limited, India’s only and the world’s largest integrated zinc producer, recently reaffirmed its commitment to climate action by reporting over 0.1 million GJ of energy savings and a reduction of more than 20,000 tCO2e in greenhouse gas emissions during FY25. The announcement coincided with National Energy Conservation Day, highlighting the company’s sustained focus on energy efficiency and decarbonisation across its Rajasthan operations. The energy savings achieved during the year are equivalent to the annual electricity consumption of nearly 19,000 Indian households, based on Ministry of Power estimates. This comparison underscores the tangible contribution of industrial energy-efficiency initiatives to national energy security and emissions reduction. Over recent years, Hindustan Zinc has implemented a wide range of measures to improve energy performance, including the deployment of variable-frequency drives, adoption of high-efficiency equipment, optimisation of smelting and process-heat systems, and AI-enabled digital monitoring for real-time energy management. The company has also strengthened its renewable energy strategy. In March 2025, it signed a round-the-clock power delivery agreement with Serentica Renewables to scale green power capacity to 530 MW, supporting its target of sourcing 70 per cent of electricity from renewable sources by FY28. These efforts align with its Science Based Targets initiative (SBTi)-validated pathway and commitment to achieving Net Zero emissions by 2050 or earlier. Arun Misra, CEO, Hindustan Zinc, stated that energy efficiency, electrified logistics and renewable power are central to reimagining mining for a low-carbon future, while reinforcing the company’s aim to set global benchmarks in sustainable mining. Earlier in FY25, Hindustan Zinc recorded GHG emission savings of 0.67 million tonnes, increased renewable energy to nearly 19 per cent of its power mix, and was ranked the world’s most sustainable metals and mining company for the third consecutive year by S&P Global. The company also became India’s first member of the International Council on Mining and Metals. Complementing its operational initiatives, Hindustan Zinc has rolled out ‘The Power of Less’, a company-wide awareness campaign promoting responsible energy use among employees and communities, reinforcing its long-term vision for a future-ready and sustainable multi-metal enterprise.
