About the company

Hindustan Zinc is a Vedanta Group company and the world's largest integrated zinc producer. It holds approximately 74% of the primary zinc market share in India and supplies to more than 30 countries. The company is also among the top 10 silver producers globally.

In recent developments, Hindustan Zinc was recognized as the world's most sustainable company in the metals and mining category by the S&P Global Corporate Sustainability Assessment 2025 for the third consecutive year. It became the first Indian company to join the International Council on Mining & Metals (ICMM) in 2025. The company launched EcoZen, Asia's first low-carbon green zinc brand, and is committed to achieving Net Zero emissions by 2050.

Hindustan Zinc submitted its Climate Action Report for FY26 to stock exchanges on October 7, 2026. The report outlines the company's strategy to reduce Scope 1 and 2 emissions by 50% from FY20 baseline levels by 2030.

The filing highlights significant progress in renewable energy integration, with total green power consumption reaching 892 million units (MU) in FY26. This shift contributed to an estimated 0.83 million tCO2e reduction in emissions. The Pantnagar Metal Plant continued to operate on 100% renewable power sourcing throughout the year.

Emissions and Renewable Energy Metrics

The company reported combined Scope 1 and Scope 2 emissions of 5.02 million tCO2e for FY26. Scope 3 emissions stood at 1.47 million tCO2e. The data indicates that while absolute emissions have increased due to operational expansion, the intensity of emissions is being managed through aggressive renewable procurement.

Decarbonisation Pathway and Investments

Hindustan Zinc's decarbonisation roadmap relies heavily on shifting from the State Transmission Utility model to the Central Transmission Utility model to reduce transmission losses. The company plans to add 990 MW of battery energy storage capacity to support green power demand for both existing and expanded capacity.

Key investments include:

• A US$1 billion commitment toward fleet electrification, targeting 75% fleet electrification by 2035.
• Approximately ₹1,114.5 crore invested in renewable energy infrastructure, including the 530 MW renewable energy programme.
• Deployment of 180 LNG vehicles and 52 electric vehicles in the logistics fleet.

Product Innovation and Market Positioning

The report emphasizes EcoZen, Asia's first low-carbon zinc product, which maintains a carbon footprint of less than 1 tCO2e per tonne of zinc. This represents an approximate 75% reduction compared to the global average. In FY26, Hindustan Zinc sold 2,935 tonnes of EcoZen, helping downstream customers avoid approximately 14,505 tonnes of CO2e emissions.

What the Numbers Show

A divergence exists between the company's growth ambitions and its near-term emissions trajectory. Hindustan Zinc plans to expand metal capacity to 2 million tonnes by 2030. This expansion increases absolute energy demand, making the 50% reduction target for Scope 1 and 2 emissions challenging despite the rapid uptake of renewable power. The reliance on battery storage and grid efficiency improvements becomes critical to offsetting the emissions impact of this volume growth.

Governance and Assurance

The report was externally assured by S.R. Batliboi & Co LLP under ISAE 3000 (Revised). Governance oversight is managed through the Board Sustainability & ESG Committee, chaired by Priya Agarwal Hebbar, which monitors progress against sustainability-linked KPIs embedded in executive remuneration.
