In recent years, the imperative for sustainable development has taken center stage across the globe, with green manufacturing emerging as a vital strategy to address climate change and environmental degradation. India, as one of the world's fastest-growing economies, finds itself at a critical juncture to balance its industrial growth with environmental sustainability. The nation generates around 2.7 billion metric tons of carbon dioxide annually, ranking third globally in emissions, according to the International Energy Agency (IEA).
India’s green manufacturing initiatives are supported by robust policy frameworks, such as the National Action Plan on Climate Change (NAPCC) and the Perform, Achieve and Trade (PAT) scheme, which collectively aim to reduce energy intensity, promote renewable energy, and improve resource efficiency. Additionally, as global supply chains pivot toward sustainability, India’s manufacturers are under growing pressure to align with international standards and cater to the rising demand for eco-friendly products. For instance, the European Union’s Carbon Border Adjustment Mechanism (CBAM) and similar regulations are reshaping export markets, incentivizing Indian industries to adopt greener practices.
Despite this progress, challenges persist. The World Bank estimates that India loses $80 billion annually due to environmental degradation, highlighting gaps in regulatory enforcement, technological adoption, and resource management. Furthermore, small and medium enterprises (SMEs), which constitute over 45% of India’s industrial output, often lack the financial and technical capabilities to transition to sustainable practices.
The Policy Framework: Paving the Way for Green Manufacturing
1. National Action Plan on Climate Change (NAPCC): Launched in 2008, the NAPCC outlines India’s strategy for mitigating climate change. Among its eight key missions, the National Solar Mission, National Mission on Enhanced Energy Efficiency (NMEEE), and National Mission for Sustainable Habitat directly contribute to green manufacturing by promoting renewable energy, energy efficiency, and sustainable industrial practices.
2. Environmental Regulations by MoEFCC: The Ministry of Environment, Forest and Climate Change (MoEFCC) plays a pivotal role in regulating emissions, waste management, and resource use in industries. Policies like the Environmental Protection Act, 1986, and the Hazardous and Other Wastes (Management and Transboundary Movement) Rules, 2016, set stringent norms for pollution control and encourage industries to adopt cleaner technologies.
3. Perform, Achieve and Trade (PAT) Scheme: The PAT scheme, a market-based mechanism under the Bureau of Energy Efficiency (BEE), aims to improve energy efficiency in energy-intensive industries. Industries exceeding their energy-saving targets can trade their excess energy-saving certificates, incentivizing efficiency improvements across sectors.
4. Incentives and Subsidies: The government offers various incentives, including tax benefits, subsidies for renewable energy adoption, and grants for research in green technologies. For instance, the Production Linked Incentive (PLI) scheme for advanced chemistry cell (ACC) battery manufacturing supports the development of sustainable energy storage solutions.
Effectiveness of Policies: Achievements and Gaps
While these policies have laid a robust foundation, their effectiveness varies due to implementation challenges and industry compliance issues. Key achievements and gaps include:
Achievements:
- India’s installed renewable energy capacity reached over 175 GW by 2022, demonstrating the success of the National Solar Mission.
- The PAT scheme has saved approximately 17 million tonnes of CO2 equivalent emissions in its first three cycles.
- Enhanced public-private partnerships have driven innovation in green manufacturing.
Challenges:
- Weak enforcement of environmental regulations and lack of monitoring mechanisms undermine the impact of policies.
- Small and medium enterprises (SMEs) often struggle with the financial and technical capacity to adopt green technologies.
- Bureaucratic delays and complex regulatory processes hinder the implementation of green initiatives.

Key Drivers of Green Manufacturing
- Environmental Regulations: Stricter regulations on emissions, waste management, and resource use push industries to innovate and adopt sustainable practices. For example, the requirement for zero liquid discharge (ZLD) in certain industries has spurred investments in wastewater recycling technologies.
- Incentives and Subsidies: Financial incentives for adopting green technologies, such as subsidies for solar energy and energy-efficient equipment, reduce the upfront costs for industries. The Faster Adoption and Manufacturing of Hybrid and Electric Vehicles (FAME) scheme, for instance, has boosted the adoption of electric vehicles and related manufacturing.
- International Agreements and Collaborations: India’s commitments under the Paris Agreement and collaborations with international organizations like the United Nations Industrial Development Organization (UNIDO) strengthen its green manufacturing initiatives. Joint ventures with global companies also bring advanced technologies to Indian industries.
- Industry-Specific Standards and Certifications: Certifications like ISO 14001 (Environmental Management Systems) and Leadership in Energy and Environmental Design (LEED) drive industries to meet global sustainability benchmarks, enhancing their competitiveness.
- Government Procurement: The government’s emphasis on procuring eco-friendly products and services provides a strong market incentive for green manufacturing. Policies mandating the use of recycled materials in public infrastructure projects are examples of such initiatives.
Emerging Trends in Green Manufacturing
- Digital Transformation: Smart factories leveraging IoT, AI, and big data are improving energy efficiency and reducing waste.
- Circular Economy: Companies are increasingly adopting circular economy models, focusing on recycling, reuse, and resource optimization.
- Renewable Energy Integration: Industries are integrating renewable energy sources into their operations, with many committing to 100% renewable energy targets.
The Path Forward
India’s policy and regulatory landscape for green manufacturing is evolving, offering significant opportunities for industries to embrace sustainability. While achievements like the PAT scheme and renewable energy capacity expansion showcase progress, challenges such as enforcement gaps and SME inclusion remain.
Stronger enforcement mechanisms, streamlined regulatory processes, and enhanced financial support for SMEs can accelerate green manufacturing adoption. Additionally, fostering innovation through public-private partnerships and international collaborations will ensure that India continues to lead in sustainable industrial practices.
By addressing these gaps and leveraging opportunities, India can achieve its climate goals and set a global example in green manufacturing—building a resilient, sustainable, and inclusive industrial ecosystem.
