Dear All,

Today, we stand at an essential juncture in our pursuit of a sustainable future. Climate action is no longer a choice but an imperative, and at Hindustan Zinc, we have embedded sustainable practices in every aspect of our operations to create a greener future for all.

I am thrilled to present Hindustan Zinc's 3rd Taskforce on Climate-Related Financial Disclosures (TCFD) report. This document is a testament to our unwavering commitment towards sustainable growth. Last year, we witnessed significant milestones that brought us closer to achieving our ambitious sustainability goals by 2025.

At Hindustan Zinc, we are driven by our bold targets to reduce our Scope 1 & Scope 2 emissions by 50%, and Scope 3 emissions by 25% by 2030. As a group, Vedanta's larger vision is to achieve Net Zero emissions by 2050, and at HZL we have taken significant steps towards

goal by signing a Power Delivery Agreement for 450 MW of renewable energy. A cleaner, better world can only be realised with positive action and scientific progress grounded in affirmative change. Innovation remains at the heart of our journey, as exemplified by the deployment of India's First Underground Battery Electric Vehicle (BEV) at Hindustan Zinc's Sindesar Khurd Mine.

Our efforts have been recognised across multiple platforms, with Hindustan Zinc ranking among the top three sustainable companies in S&P Global Corporate Sustainable Assessment, and achieving an impressive 'A' rating in the climate change category by CDP. Under our ESG vision we are committed to driving sustainable economic development and value creation for our stakeholders.

Together, let us harness the power of sustained collective action and undertake this transformative journey towards a greener future.

Message from the CEO

I strongly believe that sustainability is not just a choice but an imperative for our long-term success and the well-being of the planet

we have signed power delivery agreement of 450 MW Renewable Energy- Round the Clock (RE-RTC), and our Pantnagar Metal plant has started sourcing 100% green power. The move is in line with our strategic purpose of reducing dependence on thermal power by scaling up our renewable energy to cover 50% of our energy requirement by 2030 and reduce the GHG emissions from our operations. During FY 2022- 23, we became the 1st company in India to introduce underground battery electric vehicle (BEV) in our operations. We have already launched passenger EVs to reduce our carbon footprint and our business partners have also introduced electric vehicles in our smelting operations. Since joining TCFD in February 2021, our company has continued to support the guidelines and are reporting the progress annually.

valuable resource for our business continuation and for nearby communities. To address this risk, we have been practicing Rainwater Harvesting, installed Zero Liquid Discharge Plant at our smelting locations and utilizing treated sewage water and other initiatives. Currently, we are 2.41 times water positive, and we further aim to become 5 times water positive by 2025.

Furthermore, we will continue to update climate risks since we recognize that the information and understanding about the climate are uncertain and need to be updated. We have structured this report in accordance with the guidelines and advice of the TCFD enabling high- value stakeholder engagement while providing comprehensive information at one place.

We are hopeful that this report will accelerate further action towards climate change

TO OUR STAKEHOLDERS,

Hindustan Zinc is pleased to present the third report aligned to the recommendations of the Task Force on Climate-Related Financial Disclosures ("TCFD"). The report is aimed at fostering future dialogue and action towards climate change mitigation plans, besides showcasing company's resilience towards climate related risks & opportunities as we transition to a clean energy future.

I strongly believe that sustainability is a way of life for our long-term success and the well-being of our planet. The greatest risk humanity is currently facing is climate change and extreme weather trends. We are making strides to address the climate catastrophe because we believe it is the right thing to do for our stakeholders and our own business. With this shared objective, both the board and management are committed to lead the climate change mitigation and adaptation efforts.

Low-carbon transition is the core of our business strategy and is further helping us in setting a

clear pathway to deliver long-term value as well as ambitious targets to decarbonize our business.

To deliberate & mitigate the impact and inform our stakeholders about our disclosure procedures for financial risks related to climate change, we released our first TCFD report in August 2021 . The report provided a comprehensive understanding of our approach to identifying, measuring, managing, monitoring, and reporting opportunities and risks related to climate change. Our second report that was released following year included analysis for each impact and transition risk in accordance with IEA steps and NDCs while this year in our third report, we analyzed our transitional risk basis IEA STEPS, APS & NZE 2050 scenarios and for physical risks we have considered Intergovernmental Panel on Climate Change's (IPCC) global scenarios, i.e., Representative Concentration Pathways (RCPs) as per the Fifth Assessment Report (Ar5).

I am delighted to share that strengthening our efforts towards decarbonization journey,

We are determined to play a significant role in shaping a sustainable future for our organization by spearheading innovative initiatives, collaborating with key stakeholders, and adopting cutting edge technologies. We believe our activities will help reducing our environmental impact across our operations, from energy consumption and waste management to water usage and emissions which is in-line with our commitment towards achieving Net Zero emission by 2050. We at Hindustan Zinc have set an ambitious target of 50% reduction in Scope 1 & Scope 2 GHG emissions, 25% reduction in Scope 3 GHG emissions by 2030 and achieving carbon neutrality by 2050.

In addition to our tangible efforts, we have taken steps to reduce the impacts of climate change by lowering emissions, advocating for low carbon strategies, and are focused on managing the potential physical risks and their impact. We are conscious of the fact that we are majorly operating in the state of Rajasthan which is water scarce area as per physical risk assessment modeling, so it is even more imperative for us to conserve this precious and

mitigation, encourage dialogue, and enhance opportunities for collaboration with our stakeholders and communities, as we continue to build a Safe, Smart & Sustainable future.

I am pleased to deliver our 3rd TCFD report.

Executive Summary

Hindustan Zinc has set an ambitious target of Net Zero GHG emissions by 2050 in-line with our commitment of a greener future. We are India's largest and only Integrated producers of Zinc Lead & Silver. We consistently strive to reduce our environmental footprint by increasing our dependency on renewable energy in line with our vision of Zero Harm - Zero Waste - Zero Discharge. We have committed to Science Based Target Initiatives (SBTi) and are proactively working to reduce direct and indirect GHG emissions. We have integrated TCFD recommendations in our business strategy.

Since we are an energy intensive industry, we have taken series of energy efficiency and emission reduction initiatives like signed Power Delivery Agreement (PDA) for 450 MW Renewable Energy- Round the Clock (RE-RTC) which will cater to more than 50% of electricity needs by 2030. As a pathbreaking initiative Hindustan Zinc is the 1st company in India to introduce Underground Battery Electric Vehicle amongst its peers.

We believe that a robust governance structure will help manage climate related risks and opportunities. Our overall Board has clear

making body in the organisation to shopfloor at sites.

We have implemented robust Enterprise Risk Management framework across all our locations. The identified climate related risks are also integrated in our risk management framework and are closely monitored. This is part of our strategy to proactively manage and mitigate any upcoming potential climate related risks.

We continuously monitor and transparently disclose our climate related metrics such as GHG emissions against Scope 1, Scope 2 & Scope 3, renewable energy consumption, water withdrawal etc. This helps us to strategize and measure our impact. Disclosures related to climate change can be found in annual Sustainability review report, Integrated annual report and CDP Climate change response.

As a responsible corporate, we intend to do more to increase the use of renewable energy in our operations. We are committed to a long- term vision that protects environmental, social, and business values for our people, communities, and nature.
