Hindustan Zinc Limited, the world’s largest integrated zinc producer and among the top five silver producers globally, has won the “Best BRSR Report – Manufacturing (Large Cap)” award at the 4th ICAI Sustainability Reporting Awards, organised by the Institute of Chartered Accountants of India (ICAI).
The recognition highlights Hindustan Zinc’s strong focus on ethical governance, responsible manufacturing practices, and transparent sustainability disclosures, aligned with globally benchmarked Environmental, Social and Governance (ESG) standards.
Recognition for Governance-Led ESG Reporting
In India, Business Responsibility and Sustainability Reporting (BRSR) is the SEBI-mandated ESG disclosure framework for the country’s top 1,000 listed companies. The award reflects growing expectations from investors and regulators for data-driven, measurable, comparable, and verifiable sustainability disclosures, moving beyond narrative reporting.
Hindustan Zinc’s FY 2024–25 BRSR was recognised for its governance-led structure and clear disclosure of material ESG indicators. These include energy and emissions, water management, biodiversity, occupational health and safety, community impact, and business conduct, presented with quantitative depth to support stakeholder decision-making.
Commenting on the achievement, Arun Misra, CEO of Hindustan Zinc, said that sustainability is deeply embedded in the company’s operating and governance philosophy.
He noted that transparent and high-quality disclosure is not merely a compliance exercise, but a critical element in building long-term trust with stakeholders. He added that as the company advances towards a responsible multi-metal future, it remains committed to combining measurable on-ground action with credible, decision-useful reporting.
Early Adopter of Sustainability Reporting in India
Hindustan Zinc has consistently taken a proactive approach to ESG transparency in India. The company voluntarily adopted BRSR reporting in FY 2021–22, one year before it became mandatory under SEBI regulations.
Over time, it has developed a robust sustainability reporting ecosystem, including:
- A Sustainability Report aligned with Global Reporting Initiative (GRI) standards
- Alignment with UN Global Compact principles
- Reporting under the Federation of Indian Mineral Industries (FIMI) Sustainable Mining Initiative
The company also publishes a Climate Action Report aligned with IFRS S2 (earlier aligned with TCFD) and became the first metals and mining company in India to release a TNFD (Taskforce on Nature-related Financial Disclosures) report.
Its Integrated Annual Report has previously been recognised by the League of American Communications Professionals (LACP) for excellence in reporting. Hindustan Zinc has also expanded voluntary disclosures on tax transparency and nature-related risks, strengthening investor confidence through globally aligned reporting practices.
Clean Energy and Decarbonisation Progress
Hindustan Zinc follows a long-term sustainability strategy focused on decarbonisation, clean energy transition, and responsible resource management across its operations.
In March 2025, the company strengthened its renewable energy roadmap by signing a round-the-clock Power Delivery Agreement with Serentica Renewables. This agreement will increase its green power capacity to 530 MW and support its goal of sourcing 70% of electricity from renewables by FY28.
This transition supports the company’s Science Based Targets initiative (SBTi)-validated decarbonisation pathway and its commitment to achieve Net Zero emissions by 2050 or earlier, in line with the UN Sustainable Development Goals.
During the year, Hindustan Zinc reported:
- Greenhouse gas emission savings of 6.7 lakh tonnes
- Increase in renewable energy share to nearly 19% of total power consumption
Recognition as the world’s most sustainable metals and mining company for the third consecutive year by the S&P Global Corporate Sustainability Assessment
The company also became India’s first member of the International Council on Mining and Metals (ICMM), reinforcing its leadership in responsible mining practices.
Multi-Metal Growth and Responsible Innovation
Hindustan Zinc continues its transformation into a multi-metal company, supported by green technologies, operational excellence, and responsible growth. The company, a part of the Vedanta Group, supplies products to over 40 countries and holds around 77% share of India’s primary zinc market.
It has also launched EcoZen, described as Asia’s first low-carbon “green zinc” brand, produced using renewable energy. EcoZen has a carbon footprint of less than one tonne of CO₂ equivalent per tonne of zinc produced, nearly 75% lower than the global industry average.
Hindustan Zinc is certified as a 3.32x water-positive company and remains committed to reaching Net Zero emissions by 2050 or earlier.
Social Impact and Energy-Transition Role
Through its social development programmes, Hindustan Zinc reports having supported the lives of 2.3 million people and is ranked among the Top 10 CSR companies in India. As an energy-transition metals producer, the company plays a critical role in supplying materials essential for long-term sustainable development.
The ICAI award further strengthens Hindustan Zinc’s position as one of India’s leading examples of sustainability-focused governance, transparent reporting, and responsible industrial growth.
