“The future of the chemical industry lies not merely in reducing emissions including Scope 3 but in becoming carbon-intelligent. A carbon-intelligent chemical industry recognizes carbon as a valuable resource that must be managed efficiently throughout its entire life cycle. This includes reducing dependence on virgin fossil carbon, maximizing carbon circularity through recycling and reuse, utilizing biomass and captured carbon dioxide as alternative carbon sources, and deploying renewable and low-carbon energy systems across manufacturing and supply chains,” asserts Prof. Ganapati D. Yadav, Bhatnagar Fellow & Former National Science Chair (ANRF) Former Vice Chancellor, Institute of Chemical Technology (ICT), Mumbai Padma Shri Awardee (2016), Distinguished Chemical Engineer & Researcher in Green Chemistry, Catalysis, Circular Economy and Sustainable Manufacturing, during this exclusive interview…
As Scope 3 emissions become a strategic priority for the chemical industry, what practical and scalable interventions are helping organizations decarbonize their extended value chains beyond manufacturing operations?
Scope 3 emissions represent the most difficult but also the most important frontier in industrial decarbonization because they occur outside the factory gate. In many chemical companies, they account for more than 70% of the overall carbon footprint. While substantial progress has been made in improving energy efficiency and reducing emissions within manufacturing facilities, the next phase of decarbonization must focus on feedstocks, logistics, product use, and end-of-life management.
My research over the last four decades has focused on developing catalytic technologies that transform renewable and waste-derived carbon resources into chemicals, fuels, and materials. I firmly believe that feedstock transformation offers the single largest opportunity for Scope 3 reduction. Replacing virgin fossil resources be they crude oil, natural gas or coal, with biomass, waste plastics, captured carbon dioxide, and green hydrogen can dramatically reduce embedded emissions throughout the value chain.
Another important intervention is the adoption of circular economy principles. Chemical recycling of plastics, valorisation of agricultural residues, industrial waste utilization, and resource recovery systems can convert environmental liabilities into economic assets. My group has demonstrated several catalytic pathways for converting waste plastics and biomass into value-added products, thereby reducing dependence on fossil carbon.
Supply chains must also become geographically smarter. Regional sourcing, multimodal low-carbon logistics, and supplier sustainability programmes can reduce transportation-related emissions. Ultimately, Scope 3 decarbonization cannot be achieved through incremental improvements alone. It requires a systems approach that integrates green chemistry, circularity, renewable feedstocks, and collaborative innovation across the entire value chain.
The transition toward a carbon-intelligent chemical industry requires moving beyond traditional carbon accounting to active carbon management across the entire value chain. The objective should not simply be reducing emissions but optimizing carbon utilization through carbon circularity, renewable feedstocks, and low-carbon energy systems.
Which parts of the industry ecosystem currently present the greatest decarbonization challenge, and how can the industry address them collaboratively?
The most significant decarbonization challenge lies in the carbon embedded within raw materials and the complexity of downstream product life cycles. Chemical manufacturers generally have direct control over their own operations ( Scope 1), but they have limited control over upstream feedstock production, transportation systems, and downstream product usage and disposal.
The chemical industry was built around fossil carbon because it was abundant, inexpensive, and supported by a mature infrastructure. Moving away from this model requires a fundamental transformation of feedstock supply chains. Renewable carbon sources such as biomass, and also waste plastics, municipal solid waste, captured carbon dioxide, and green hydrogen offer promising alternatives, but they require new technologies, logistics networks, and investment frameworks.
My own work in green chemistry and heterogeneous catalysis has focused extensively on creating economically viable pathways for converting biomass and waste into chemicals, fuels and materials. Such technologies demonstrate that decarbonization can be achieved without sacrificing industrial competitiveness. A carbon-intelligent chemical industry must ensure that carbon flows are optimized across international supply chains, irrespective of geographical boundaries.
The logistics sector also presents a major challenge. Chemical supply chains are global, involving multiple transport modes and thousands of intermediaries. Significant emission reductions will require coordinated efforts among producers, logistics providers, ports, warehousing companies, and customers.
The solution lies in collaborative ecosystems rather than isolated initiatives. Industry, academia, government, and technology developers must work together to create common carbon accounting standards, shared infrastructure for hydrogen and carbon utilization, and scalable circular economy platforms. Decarbonization is not merely a technical challenge; it is an ecosystem challenge requiring collective action.
Because the chemical industry is inherently transnational, with supply chains extending across continents, its decarbonization challenges have always been global in nature. The challenge is not simply reducing emissions in one facility but optimizing carbon utilization throughout the global industrial ecosystem.
How is Scope 3 performance influencing procurement decisions, customer relationships, and long-term competitiveness for chemical companies?
Scope 3 performance is rapidly evolving from a sustainability metric into a strategic business differentiator. Increasingly, customers are not merely purchasing chemicals; they are purchasing the embedded environmental attributes associated with those chemicals. As a result, carbon intensity is becoming as important as quality, cost, reliability, and technical performance. Customers are increasingly demanding evidence of carbon intelligence, including transparent carbon footprints, carbon circularity metrics, and sustainable sourcing practices.
Many multinational corporations have committed to ambitious net-zero targets. Consequently, they are placing increasing pressure on suppliers to provide transparent life-cycle carbon data and demonstrate measurable progress toward emissions reduction. Chemical companies that fail to address Scope 3 emissions may find themselves excluded from preferred supplier lists and high-value international markets. Future procurement decisions will increasingly favour suppliers who demonstrate superior carbon management capabilities and low-carbon product portfolios.
From my perspective as a researcher, innovator, technology developer and policy maker, this trend creates tremendous opportunities for innovation. Green chemistry, catalytic process intensification, renewable feedstocks, and circular manufacturing systems can generate products with significantly lower environmental footprints. Such products command greater acceptance in environmentally conscious markets and strengthen customer confidence.
I have long advocated that sustainability should not be viewed as a compliance burden but as a source of competitive advantage. Companies that invest early in carbon-efficient technologies, circular economy solutions, and transparent sustainability reporting will be better positioned to secure market access, attract investment, and build long-term customer relationships.
In the coming decade, carbon footprint data may become as routine as product specifications. Organizations that can demonstrate credible reductions across their entire value chain will enjoy a distinct competitive advantage in global markets. Carbon performance is rapidly becoming a proxy for innovation capability and long-term business resilience.
How can chemical companies improve data transparency, emissions traceability, and sustainability alignment across fragmented supplier and partner networks?
Supplier engagement is perhaps the most challenging aspect of Scope 3 management because chemical supply chains often involve hundreds or even thousands of suppliers operating across different geographies and levels of technological maturity. The Hormuz crisis in the West Asia demonstrated this vulnerability. One cannot manage what one cannot measure, and therefore data transparency must become the cornerstone of sustainability initiatives.
In my view, the first requirement is the adoption of standardized methodologies for carbon accounting and life-cycle assessment. Unless all stakeholders speak the same language and use comparable metrics, meaningful benchmarking and improvement become impossible. Sustainability data should become as important as cost, quality, and delivery performance during supplier evaluation.
Digital technologies will play an increasingly important role. Carbon intelligence platforms, blockchain-enabled traceability systems, and AI-assisted data analytics can improve the reliability and visibility of emissions information throughout the supply chain. However, technology alone is not sufficient. Large organizations must actively support smaller suppliers by providing technical guidance, training, and access to cleaner technologies. Digital carbon intelligence systems will become essential tools for tracking carbon flows across complex transnational supply chains.
Throughout my career, I have observed that innovation flourishes when knowledge is shared rather than restricted. The same principle applies to sustainability. Companies should view suppliers as partners in decarbonization rather than mere vendors. Collaborative programmes involving industry, academia, and technology providers can accelerate the adoption of cleaner processes and materials. The future objective should be end-to-end carbon traceability, where every significant carbon input and output can be measured, monitored, and optimized.
Ultimately, successful Scope 3 management will depend on creating trusted ecosystems where environmental performance is measured consistently, reported transparently, and rewarded commercially. Supplier engagement must evolve from data collection toward collaborative carbon management.
Which emerging innovations or ecosystem partnerships do you believe can create the biggest long-term impact on indirect emissions reduction?
As someone who has spent decades working in green chemistry, catalysis, biomass valorisation, waste plastics recycling, and sustainable process development, I believe that circular carbon utilization will be one of the most transformative developments of the twenty-first century. Carbon circularity represents one of the most important pillars of the carbon-intelligent chemical industry.
Historically, the chemical industry has operated on a linear model based on extraction, production, consumption, and disposal. This model is no longer sustainable. The future lies in retaining carbon within the economic system for as long as possible through recycling, reuse, and conversion into higher-value products. Recycle engineering will be the prevalent theme by the mid of this century. Nothing virgin will be available.
My research group has demonstrated catalytic routes for converting lignocellulosic biomass, waste plastics, and carbon dioxide into fuels, chemicals, and advanced materials. These technologies show that waste streams can become valuable feedstocks rather than environmental burdens. In fact, I always talk about net negative (carbon) systems as one of the pillars of modern chemical industry. Carbon-free or low-carbon technologies will come to the central stage. Chemical recycling of mixed plastic waste, catalytic hydrogenolysis, biomass-based biorefineries, and carbon capture and utilization (CCU) technologies have the potential to significantly reduce indirect emissions. Through advanced catalysis, waste carbon can be transformed into valuable chemicals, fuels, and materials, thereby extending the productive life of carbon atoms.
Green hydrogen will also play a transformative role. It can serve both as a clean energy carrier and as a sustainable feedstock for numerous chemical processes. When combined with captured carbon dioxide, green hydrogen can facilitate the production of fuels and chemicals with substantially lower carbon footprints. Green hydrogen, renewable electricity, biomass, recycled plastics, and captured carbon dioxide will form the foundation of future carbon-managed value chains.
The greatest breakthroughs will emerge from partnerships among industry, academia, start-ups, government agencies, and financial institutions. Sustainability challenges are too complex for isolated solutions. Integrated innovation ecosystems will determine how rapidly we transition toward a circular and low-carbon chemical economy. The goal should be to keep carbon circulating within the economy for as long as possible before it is ultimately returned to the atmosphere.
How are the upcoming digital technologies helping chemical companies improve emissions visibility, operational efficiency, and sustainability decision-making?
Digital technologies are enabling the emergence of carbon intelligence as a core management function. The future of sustainable manufacturing will be driven by the convergence of chemistry, engineering, and digital technologies. We are entering an era where artificial intelligence and advanced analytics can significantly accelerate both operational excellence and environmental performance.
Traditionally, environmental management relied heavily on historical reporting and periodic audits. Today, digital technologies enable real-time monitoring, predictive decision-making, and proactive optimization. AI algorithms can analyse vast quantities of operational data to identify inefficiencies, reduce energy consumption, optimize logistics routes, and minimize waste generation.
Digital twins are particularly promising. By creating virtual replicas of manufacturing facilities and supply chain networks, organizations can evaluate alternative operating strategies before implementing them in practice. This reduces both economic and environmental risks while improving resource efficiency. AI, predictive analytics, and digital twins allow organizations to move from carbon reporting to carbon optimization.
From a research perspective, AI is also revolutionizing catalyst discovery, reaction engineering, and process development. Many of the catalytic systems that my group has developed required extensive experimentation. Future generations of researchers will increasingly use machine learning tools to accelerate catalyst design and process optimization.
Carbon intelligence platforms further enable companies to track emissions across multiple tiers of suppliers and customers, providing a comprehensive view of Scope 3 impacts. Such visibility allows organizations to identify emission hotspots and prioritize investments where they can achieve the greatest benefit. Future carbon-intelligent enterprises will operate digital carbon management systems analogous to modern financial management systems.
The most successful companies of the future will be those that combine scientific innovation with digital intelligence to create sustainable, resilient, and competitive supply chains. The combination of advanced catalysis and artificial intelligence will be a powerful driver of sustainable innovation.
What policy support, financing mechanisms, or industry collaborations are essential to make Scope 3 transition efforts commercially scalable?
The transition to low-carbon supply chains is not merely a technological challenge; it is also an economic and policy challenge. Many promising technologies already exist, but their large-scale deployment often requires supportive policy frameworks and innovative financing mechanisms. Governments can play a critical role by creating stable and predictable policies that encourage investment in green technologies, renewable energy systems, carbon utilization, advanced recycling, and green hydrogen infrastructure. Incentives for industrial decarbonization should focus not only on direct emissions but also on emissions across the entire value chain. Governments should encourage investments not only in emissions reduction but also in carbon circularity infrastructure.
Equally important is the availability of patient capital. Sustainability projects often involve long payback periods and higher initial costs. Green bonds, sustainability-linked loans, blended finance mechanisms, and public-private partnerships can help bridge this gap and accelerate commercialization. This is again a policy issue including green hydrogen infrastructure, CCU, advanced recycling hubs, renewable electricity networks and sustainable logistics corridors.
I have always believed that universities and research institutions have a crucial role in translating scientific discoveries into industrial practice. Stronger collaboration among academia, industry, government, and financial institutions can significantly reduce the risks associated with technology deployment. The history of the chemical industry demonstrates that transformative innovations emerge when science, policy, and entrepreneurship work together. The same principle will apply to Scope 3 decarbonization. We must create ecosystems that reward long-term sustainability investments rather than short-term economic gains alone. The transition toward a carbon-intelligent chemical industry requires long-term policy stability and patient capital.
What will define a truly future-ready and sustainable chemical supply chain ecosystem, and how can the industry move from isolated sustainability initiatives toward integrated, ecosystem-wide transformation?
A truly future-ready chemical supply chain will be circular, carbon-efficient, digitally connected, transparent, and resilient. Sustainability will no longer be a separate corporate programme; it will become an integral part of business strategy, product design, procurement, manufacturing, logistics, and customer engagement. India’s contribution to this sector will be at least two trillion USD by mid of this Century.
The defining characteristic of future supply chains will be circularity. Carbon atoms already present in biomass, plastics, industrial waste streams, and carbon dioxide emissions must be repeatedly reused rather than continuously extracted from fossil resources. This philosophy has guided much of my own research in green chemistry, catalysis, biomass valorisation, waste plastics recycling, and carbon utilization. Carbon accounting will evolve into carbon management and ultimately into carbon optimization, where carbon is treated as a strategic resource rather than merely a source of emissions.
Future supply chains will also be highly data-driven. Real-time visibility of material flows, energy use, carbon footprints, and resource efficiency will enable better decision-making and greater accountability across the value chain. Renewable electricity, green hydrogen, advanced catalysis, CCU, and circular manufacturing systems will become integral components of future industrial ecosystems. However, technology alone cannot achieve transformation. The transition requires a cultural shift toward collaboration. Industry, academia, government, financial institutions, and society must work together to create integrated solutions. Individual companies can optimize their own operations, but only collaborative ecosystems can transform entire value chains.
The chemical industry has historically been a catalyst for societal progress through innovation. Today, it has an equally important opportunity to lead the transition toward a sustainable and circular economy. Those organizations that embrace systems thinking, invest in innovation, and collaborate across traditional boundaries will define the future of global manufacturing and supply chains.
The chemical industry has historically transformed society through scientific innovation. In the coming decades, its greatest contribution may be the creation of a carbon-intelligent global manufacturing ecosystem in which every carbon atom is valued, managed, optimized, and, wherever possible, continuously recycled. This transformation will require unprecedented collaboration among industry, academia, governments, financial institutions, and society, reflecting the fundamentally global nature of both the chemical industry and the sustainability challenges it seeks to address.
