Understanding the S&P Global Sustainability Yearbook
The S&P Global Sustainability Yearbook is widely regarded as one of the most rigorous and respected benchmarks for evaluating corporate sustainability performance worldwide.
Each year, thousands of companies across a wide range of industries are assessed through the S&P Global Corporate Sustainability Assessment, a detailed evaluation of how companies manage environmental, social and governance risks and opportunities.
In the most recent assessment cycle, more than 9,200 companies across 59 industries were evaluated. Only 848 companies qualified for inclusion in the yearbook, representing those that demonstrate the strongest sustainability performance within their respective sectors.
The top 10 per cent ranking is reserved for companies that significantly outperform their global peers on ESG metrics. These companies are considered leaders in areas such as environmental stewardship, risk management, corporate transparency and responsible business practices.
For companies operating in energy-intensive sectors such as metals and mining, achieving this ranking is particularly significant due to the environmental challenges associated with large-scale industrial production.
Vedanta Aluminium’s inclusion therefore signals growing recognition of its sustainability initiatives and its efforts to reduce environmental impacts while maintaining operational efficiency.
Environmental Progress Behind the ESG Score
Vedanta Aluminium’s strong ESG performance is supported by measurable improvements across several environmental indicators.
One of the most important indicators relates to greenhouse gas emissions intensity, which measures the amount of emissions generated per tonne of aluminium produced.
Since the financial year 2021, the company has reduced its emissions intensity by nearly 9 per cent, lowering it to 17.01 tonnes of CO₂ equivalent per tonne of aluminium.
This improvement reflects efforts to increase energy efficiency across production processes while expanding the use of cleaner energy sources.
Renewable energy adoption has also become a key component of the company’s sustainability strategy.
During the financial year 2025, Vedanta Aluminium consumed approximately 1.57 billion units of renewable energy, helping reduce its reliance on fossil fuels and lower its overall carbon footprint.
The company has also made notable progress in waste management and resource efficiency.
In FY25 alone, Vedanta Aluminium recycled more than 14.6 million tonnes of waste, demonstrating its commitment to circular economy principles.
Another important achievement is the company’s 100 per cent fly ash utilisation, meaning all fly ash generated during operations is reused rather than disposed of in landfills.
Fly ash is a by-product of thermal power generation and is often used in cement manufacturing, road construction and other industrial processes.
By fully utilising this by-product, Vedanta Aluminium reduces waste while supporting resource efficiency in other industries.
Water Management and Sustainable Operations
Water management is another critical area within the company’s sustainability programme.
Industrial operations can place significant pressure on local water resources, particularly in regions where water scarcity is already a concern.
To address this challenge, several Vedanta Aluminium facilities now operate zero liquid discharge (ZLD) systems.
These systems ensure that wastewater generated during industrial processes is treated and recycled for reuse within the facility rather than being released into nearby ecosystems.
The adoption of zero liquid discharge technology helps reduce water consumption while minimizing the environmental impact of industrial operations.
In addition to water recycling, the company has implemented various efficiency measures aimed at improving resource management across its production facilities.
These include improvements in energy efficiency, process optimisation and the adoption of new technologies designed to reduce emissions and resource consumption.
Expanding Renewable Energy Capacity
Looking ahead, Vedanta Aluminium plans to expand its renewable energy infrastructure as part of its long-term climate strategy.
The company has announced plans to develop 1,500 megawatts of renewable energy capacity by 2030, which will significantly increase the share of clean energy used in its operations.
Renewable energy projects are expected to include a combination of solar and wind power installations, helping reduce the carbon intensity of aluminium production.
This expansion supports the company’s broader ambition to achieve net-zero greenhouse gas emissions by 2050 or earlier.
Reducing emissions within the aluminium sector is a major global challenge because aluminium production is highly energy-intensive.
However, many industry leaders are increasingly investing in renewable energy and advanced technologies to reduce the environmental impact of production.
Vedanta Aluminium’s renewable energy expansion is therefore expected to play an important role in supporting both its internal sustainability targets and broader industry decarbonisation efforts.

ESG Impact Beyond Environmental Initiatives
Vedanta Aluminium’s ESG initiatives extend beyond environmental improvements to include social development and community engagement programmes.
Through its social impact initiatives, the company currently reaches more than 1.75 million women and children across the Indian states of Odisha and Chhattisgarh.
These programmes focus on improving access to education, healthcare services and economic opportunities, particularly for women and marginalized communities.
Education initiatives include support for schools, scholarships and digital learning programmes designed to improve educational outcomes in rural areas.
Healthcare initiatives focus on improving access to medical services, preventive healthcare programmes and community health awareness campaigns.
The company has also introduced programmes aimed at supporting women’s empowerment and entrepreneurship, helping women gain access to skills training, financial literacy and income-generating opportunities.
Such initiatives aim to strengthen community resilience while improving quality of life in regions surrounding Vedanta Aluminium’s operational sites.
Biodiversity and Environmental Restoration
In addition to its emissions reduction efforts, Vedanta Aluminium is also working on initiatives designed to protect and restore local ecosystems.
These efforts include biodiversity restoration projects focused on improving habitats and protecting natural ecosystems around operational sites.
The company is also investing in research related to bauxite residue management, an important environmental challenge associated with aluminium refining.
Bauxite residue, commonly known as red mud, is a by-product generated during the extraction of alumina from bauxite ore.
Managing this residue safely and efficiently is critical to reducing environmental impacts associated with aluminium production.
Vedanta Aluminium’s research initiatives aim to develop new techniques for managing and potentially repurposing this material, supporting both environmental protection and resource efficiency.
Sustainability as a Core Business Strategy
According to company leadership, sustainability is increasingly becoming a central pillar of Vedanta Aluminium’s long-term growth strategy.
Rajiv Kumar, Chief Executive Officer of Vedanta Aluminium, said the recognition reflects the company’s commitment to responsible production and long-term value creation.
“Being recognized among the top 10 per cent of global companies in the Sustainability Yearbook 2026 is a milestone for Vedanta Aluminium,” Kumar said.
“Sustainability is central to our growth strategy, shaping how we innovate, operate and create long-term value for our stakeholders.”
He added that the recognition reinforces the company’s commitment to continuous improvement as it works toward building a globally competitive and future-ready aluminium business.
By integrating sustainability considerations into operations, innovation and corporate strategy, the company aims to strengthen its competitiveness while reducing environmental risks.
ESG Performance and Investor Expectations
The growing importance of ESG performance is also influencing how investors evaluate companies across industries.
Institutional investors increasingly incorporate sustainability metrics into their investment decisions, viewing strong ESG performance as an indicator of long-term resilience and risk management.
Benchmarks such as the S&P Global Corporate Sustainability Assessment provide investors with valuable insights into how companies manage environmental impacts, governance practices and social responsibilities.
Companies that perform well in these assessments may find it easier to attract investment, particularly from funds focused on sustainable or responsible investing strategies.
For energy-intensive industries such as metals and mining, demonstrating progress on ESG metrics can be particularly important in maintaining investor confidence.
Vedanta Aluminium’s strong performance in the sustainability yearbook therefore highlights its ability to align industrial production with evolving investor expectations.
Outlook: Sustainability as a Competitive Advantage
Vedanta Aluminium’s rising ESG rankings reflect a broader transformation taking place within the global metals and mining industry.
As governments strengthen environmental regulations and investors place greater emphasis on sustainability performance, companies are increasingly required to balance industrial growth with environmental responsibility.
Reducing emissions, improving energy efficiency and adopting circular economy practices are becoming essential components of long-term competitiveness.
Vedanta Aluminium’s progress in renewable energy adoption, waste management and community engagement suggests that companies integrating sustainability into their core strategies may be better positioned to navigate this evolving landscape.
With continued investments in clean energy, environmental innovation and social development programmes, the company aims to strengthen its position as a responsible producer while supporting the global transition toward more sustainable industrial production.
