• EV bus fleet flagged off at company’s Zinc Smelter Debari plant as part of a larger 41 bus deployment

• Expected to offset over 11,000 tonnes of CO₂e over the contract tenure

• Transition from diesel to electric buses to support Scope 3 emissions reduction

Hindustan Zinc Limited, the world’s largest integrated zinc producer and among the top ten global silver producers, recently flagged off the Rajasthan’s first & largest fleet of electric buses in partnership with Enviiiro Wheels Mobility Pvt. Ltd. at its Zinc Smelter Debari business unit in Udaipur, marking a significant milestone in its green mobility journey. This initiative is part of a larger deployment of 41 electric buses across Hindustan Zinc’s tech-first operations in Rajasthan aimed at decarbonizing employee transportation and reducing Scope 3 emissions.

The launch of this new electric bus fleet builds on Hindustan Zinc’s broader efforts to transition to low-emission transport systems. By replacing diesel buses with electric alternatives, Hindustan Zinc is set to save an estimated 11,000 tonnes of CO₂e over the contract period, translating climate commitments into tangible emissions reduction on the ground. The rollout of the first fleet of electric buses at Zinc Smelter Debari represents a key step in translating this commitment into tangible action on the ground.

Speaking on the occasion, Mr. Arun Misra, CEO, Hindustan Zinc, said “At Hindustan Zinc, our transition to sustainable mobility reflects a fundamentally different way of thinking about industrial growth. Aligned with our membership in the International Council on Mining and  Metals, we are embedding climate responsibility initiatives into everyday operations, translating global commitments into measurable action on the ground. The introduction of electric buses for employee transport is a step towards decarbonising our value chain, advancing our Net Zero ambition for 2050 or earlier, and building a future‑ready mining ecosystem.”

Aligned with its Science Based Targets initiative (SBTi) validated commitments and its membership in the International Council on Mining and Metals (ICMM), Hindustan Zinc continues to demonstrate leadership in climate action by embedding sustainability at the core of its operational strategy.

Over the years, the company has rolled out a comprehensive and integrated programme to enhance energy efficiency, significantly reduce its carbon footprint, and fast‑track the transition to clean energy. HZL has increased the share of renewable energy to nearly 18% of its total power mix, underscoring tangible progress toward its decarbonisation goals. A significant milestone in this journey is the company’s 530 MW round‑the‑clock renewable energy power delivery agreement, which is expected to meet over 70% of Hindustan Zinc’s total power requirement. The first flow of renewable energy under this agreement has already commenced in the previous fiscal, marking a decisive shift towards cleaner energy sourcing.

Reinforcing this leadership, Hindustan Zinc was recognized as the world’s most sustainable metals and mining company for the third consecutive year in the S&P Global Corporate Sustainability Assessment 2025. 

Through sustained investments in renewable energy, energy efficiency, and green mobility solutions, Hindustan Zinc is accelerating its transition towards a cleaner, low‑carbon industrial ecosystem while advancing sustainability at scale, one responsible commute at a time.
