Hindustan Zinc Tops S&P Global Sustainability Rankings for Third Year

Hindustan Zinc, India’s only and the world’s largest integrated zinc producer and one of the top five global silver producers, has maintained its No. 1 global position in the Metals & Mining sector in the S&P Global Corporate Sustainability Assessment (CSA) 2025. As of 5 November 2025, the company earned an industry-leading score of 90, ranking first among 235 companies worldwide—its highest CSA score in five years and a continuation of its leadership for the third straight year.

The S&P Global CSA is one of the world’s most respected ESG benchmarks, evaluating companies on comprehensive environmental, social, and governance criteria. Hindustan Zinc improved its score from 86 in the 2024 assessment, earning top marks in Climate Strategy, Community Relations, and Waste & Pollutants management.

This recognition reaffirms Hindustan Zinc’s position as the world’s most sustainable metals and mining company and reflects its strong performance across environmental stewardship, renewable energy transition, water conservation, circularity, safety, and social impact.

The company continues to lead with innovations such as EcoZen—Asia’s first low-carbon zinc—and its broader decarbonisation roadmap. Hindustan Zinc is a 3.32-times water-positive organisation and recently became the first Indian company to join the International Council on Mining & Metals (ICMM). Its long-term sustainability commitments are backed by operational excellence, responsible growth, and value creation across the value chain.

Commenting on the achievement, Priya Agarwal Hebbar, Chairperson, Hindustan Zinc, said:

“Being recognized as the world’s most sustainable company in the Metals & Mining sector for the third consecutive year is a proud and humbling moment for all of us at Hindustan Zinc. This recognition reflects our deep-rooted commitment to ESG excellence and our relentless pursuit of responsible and inclusive growth. It is the compass that directs our journey—shaping every innovation, partnership, and step toward a more sustainable tomorrow.”

Hindustan Zinc continues to champion global best practices, advance transparent ESG reporting, and work toward its Net Zero 2050 goal. The company has embedded circular economy principles across operations, with over 30% of water use met through recycled or treated sewage water. It aims for zero waste to landfill and is expanding renewable energy sourcing, supported by a 530 MW Power Delivery Agreement that will enable it to use 70% renewable electricity by FY2028.

Decarbonisation efforts also include the transition to electric and low-emission vehicles and the deployment of digital systems under its smart mining initiative. Beyond environmental leadership, the company’s social programmes in education, healthcare, livelihoods, and women’s empowerment benefited over 2.3 million people in FY2025. Its biodiversity projects further strengthen its commitment to conservation and sustainable development.

With sustainability deeply ingrained in its business strategy, Hindustan Zinc continues to set global benchmarks and exemplify India’s growing leadership in responsible and resilient industrial practices.
