Hindustan Zinc Saves GHG Emissions Equivalent to Powering 4 Lakh Homes

14 Jul 2025 CW Team

In FY25, Hindustan Zinc consumed 636 million units of renewable power, sourced through a combination of captive generation and power imports. According to data shared by the Ministry of Power, the average annual electricity consumption per Indian household stood at approximately 1,538 kWh. Based on this metric, the GHG emissions saved by the company in FY25 is enough to meet the annual electricity needs of over 4 lakh Indian homes annually. This compelling equivalence reinforces Hindustan Zinc’s leadership in decarbonisation and highlights its measurable contribution to advancing the clean energy transition.

Recognized as the world’s most sustainable company in metals & mining sector by S&P Global Corporate Sustainability Assessment 2024, the company recently announced its ambitious 2030 Sustainable Development Goals (SDG). The goals cover ambitious targets spanning various thematic areas such as climate change, water stewardship, biodiversity conservation, responsible sourcing, circular economy, safety & wellbeing, workforce diversity and social impact. The company has committed to achieving 50 per cent reduction of Scope 1 and 2 emissions and 25% reduction of Scope 3 emissions from the 2020 baseline.

Taking forward the vision of responsible and sustainable manufacturing, Hindustan Zinc achieved a significant milestone by sourcing c.13 per cent of its total power mix from renewable sources in FY25 with an ambitious target to source 70 per cent by FY28. Notably, the company has also signed power delivery agreements for round-the-clock renewable energy up to 530 MW. This marks a key step forward in the company’s long-term vision to achieve Net Zero by 2050 or sooner. The company also continues to invest in innovative energy-efficiency projects such as revamping of all the turbines in its captive power plants, improvement of cellhouse efficiency, installation of variable frequency drives across operations, switching to alternate fuel sources, resulting in energy savings and reduced carbon emissions across its value chain.

Earlier last year, Hindustan Zinc started receiving the first flow of renewable power that was utilized in the production of Asia’s first low-carbon ‘green’ zinc – EcoZen. It is a strategic imperative for the company to reduce dependence on conventional sources of energy thereby reducing carbon emissions across every process stage. As a result of this unwavering focus, Hindustan Zinc has reduced its GHG (greenhouse gas) emissions intensity by 15 per cent in FY25 over year 2020 baseline while increasing production volumes.

Notably, Hindustan Zinc was the first Indian company in the metals & mining sector to secure validated Science Based Targets Initiative (SBTi) targets, aligning with the ambitious 1.5°C global warming threshold. Further establishing its strong commitment to sustainability, the company’s zinc product is Environmental Product Declaration (EPD) verified thus providing comparable data on the product’s environmental footprint.

On Global Energy Independence Day, Hindustan Zinc, India’s only and the world’s largest integrated zinc producer, reaffirmed its strong commitment to climate action by recording 6,70,000 tCO2e greenhouse gas (GHG) emission savings in FY25 surpassing its Sustainable Development Goals (SDG) 2025 target of 5 lakh tCO2e. To put this into context, the GHG emission savings due to renewable energy is equivalent to powering more than 4 lakh Indian homes for a year. With a clear focus on accelerating the transition to clean energy and improving operational efficiency, the company continues to embed sustainability at the core of its operations. In FY25, Hindustan Zinc consumed 636 million units of renewable power, sourced through a combination of captive generation and power imports.
