####Hindustan Zinc Secures Top 1% Ranking in S&P Global Sustainability Yearbook 2026

Udaipur,  Hindustan Zinc Limited (BSE: 500188; NSE: HINDZINC), the world’s largest integrated zinc producer and amongst the top five silver producers globally, has been included in the S&P Global Sustainability Yearbook 2026, securing a place in the Top 1% of companies worldwide in Metals & Mining (MNX) industry based on its Corporate Sustainability Assessment (CSA) score of 90/100. The ranking, announced by S&P Global as part of its annual evaluation of corporate sustainability performance, recognises companies demonstrating industry-leading performance across environmental, social and governance (ESG) parameters. This milestone follows Hindustan Zinc being ranked as the world’s most sustainable metals & mining company in the S&P Global CSA 2025, for the third consecutive year, reinforcing its global leadership in responsible mining.

This marks the company’s ninth consecutive inclusion in the Sustainability Yearbook and its third straight year in the Top 1% category, reflecting sustained performance across climate strategy, water stewardship, organisational workplace practices, governance standards and risk management. Out of over 9,200 companies across 59 industries that were assessed for this year’s Sustainability Yearbook, only 848 are Yearbook Members. The Top 1% distinction is awarded to a select group of global companies that consistently demonstrate superior ESG performance relative to sector peers.

The recognition adds to a series of recent sustainability-linked milestones for Hindustan Zinc. The company received the ‘Best BRSR Report – Manufacturing (Large Cap)’ at the 4th ICAI Sustainability Reporting Awards for its FY25 Business Responsibility and Sustainability Report, recognised for its governance-led structure, strong quantitative disclosures and transparency. Its Integrated Annual Report FY25 & Sustainable Development Report 2025 also earned ‘Platinum Worldwide’ recognition at the LACP Spotlight Awards 2025, ranking 1st in India and 6th globally among over 500 submissions.

Speaking on the achievement, Mr. Arun Misra, CEO, Hindustan Zinc Limited, said:

“Being ranked in the Top 1% of the S&P Global Sustainability Yearbook for the third consecutive year is a matter of immense pride for all of us. This recognition reflects our consistent efforts to integrate sustainability into every aspect of our operations, from responsible mining and decarbonisation to community development and governance excellence. It strengthens our resolve to continue setting global benchmarks as we build a resilient, future-ready and sustainable metals business.”

Hindustan Zinc has continued to advance its long-term sustainability roadmap through focused climate action, clean energy adoption and responsible resource management. In March 2025, the company signed a round-the-clock renewable Power Delivery Agreement with Serentica Renewables, a move expected to increase its green energy capacity to 530 MW and support its target of meeting 70% of its electricity requirement through renewables by FY28. The initiative forms a key part of its SBTi-approved decarbonisation pathway and its commitment to achieving Net Zero emissions by or before 2050.

Over the past year, the company achieved a reduction of approximately 6.7 lakh tonnes in greenhouse-gas emissions and increased the share of renewables in its power portfolio to nearly 19%. It also strengthened its global responsible-mining credentials by becoming the first Indian metals and mining company to join the International Council on Mining and Metals (ICMM), reaffirming its commitment to the highest international environmental and social performance standards.

This continued global recognition solidifies Hindustan Zinc’s commitment to embedding sustainability at the core of its growth strategy and reinforces its position as one of the world’s leading responsible metals companies, driving long-term value through climate-aligned operations, innovation and inclusive development. The company continues to steer the metals and mining industry toward a more resilient, responsible, and future-ready ecosystem, aligning its growth with climate goals, societal expectations, and global sustainability standards.
