Hindustan Zinc Limited, India’s largest zinc producer and the second-largest globally, has earned a prestigious Top 1% ranking in the S&P Global Sustainability Yearbook 2025. This achievement marks the company’s eighth consecutive inclusion and the second year in the Top 1%, reinforcing its commitment to sustainability and responsible business practices.
The recognition follows Hindustan Zinc’s recent distinction as the most sustainable metals and mining company in the S&P Global Corporate Sustainability Assessment (CSA) 2024, highlighting its efforts in environmental, social, and governance (ESG) initiatives. To be featured in the S&P Global Sustainability Yearbook, companies must rank in the top 15% of their industry and score within 30% of the highest performer in their sector.
This year, 780 companies out of 7,690 assessed across 62 industries earned a spot in the Yearbook, underscoring Hindustan Zinc’s leadership in sustainable practices. The company also ranked among the top 66 global companies, further demonstrating its focus on sustainable and responsible manufacturing.
Hindustan Zinc is actively working on its Net Zero roadmap, with a target to achieve carbon neutrality by 2050 or earlier. The company has already reduced its greenhouse gas emission intensity by 14% compared to 2020 levels, while increasing production. It is also committed to sourcing over 70% of its energy from renewable sources by 2027 and has signed a 530 MW round-the-clock power delivery agreement.
In addition, Hindustan Zinc has maintained a water-positive status, being 2.41 times water positive, and has reduced freshwater withdrawal by 8.67% since FY20. The company’s social impact initiatives have made a difference in the lives of 2 million people across 40,000 villages, focusing on education, healthcare, skill development, and rural infrastructure.
Arun Misra, CEO of Hindustan Zinc, commented on the achievement: “Being ranked in the top 1% of the S&P Global Sustainability Yearbook for the second year in a row shows our dedication to sustainability. Responsible operations, innovation, and ESG leadership are key to our journey. As the world moves toward a low-carbon economy, our zinc and silver will play an important role in supporting this transition. We remain focused on creating long-term value for all stakeholders while integrating sustainability into every aspect of our business.”
Hindustan Zinc is the first Indian metals and mining company to gain validation from the Science-Based Targets Initiative (SBTi), aligning with the 1.5°C global warming target. The company is further strengthening its green energy transition by integrating renewable energy, improving operational efficiency, and adopting cleaner fuels and electric vehicles.
Recently, Hindustan Zinc launched EcoZen, Asia’s first low-carbon “green” zinc, which has a carbon footprint 75% lower than the global average. Its product range is also verified by the Environmental Product Declaration (EPD), ensuring transparency in environmental impact. In addition, the company’s climate action efforts were recognized by the Carbon Disclosure Project (CDP) 2023, earning an A- Leadership Band rating for its work on water security and climate change.
