The chemical industry is bedrock of modern civilization and critical pillar of the global economy contributing to agriculture, healthcare, construction and manufacturing worldwide. Globally this sector contributes to over USD 5 trillion and accounts approx. 7% of global GDP with the production hubs spread across Asia, Europe and North America. India alone contributes more than 7% to its national GDP and is the sixth largest chemical producer in the world. It is projected to grow to USD 300 billion by 2025 making it one of the fastest growing chemical markets.
Although this rapid progress will have its own challenges which includes Green House Gas (GHG) emissions. The chemical sector is also considered among the largest emitters of GHG and they are responsible for nearly 20% of industrial CO2 emissions worldwide. Beyond carbon emission, the industry faces global scrutiny for generating toxic waste, hazardous effluents, Air pollutants and energy intensive process that strain ecosystem and public health.
With over 70 countries committing to Net Zero targets, including India by 2070 , the chemical industry worldwide stands at a crucial cross roads. It transformation towards low – carbon, resource – efficient and circular production system will determine not only national progress but also the collective ability to achieve global climate goals.
- Why Net ZERO matters for Chemical Industry
The global push for climate action is no longer optional — it is a business imperative. Net-zero goals offer a strategic opportunity for chemical firms to become competitive, compliant, and climate-resilient (together named as 3Cs). The below mentioned points navigates company progress towards emission reduction through the above mentioned 3 Cs.
ü Investor and Regulatory Pressures
Global investors and ESG (Environmental, Social, Governance) frameworks are increasingly demanding low-carbon pathways from high-emission industries. Disclosure frameworks like BRSR (Business Responsibility and Sustainability Reporting) in India or TCFD globally are becoming mandatory for large companies.
ü Global Trade and Supply Chain Alignment
Exporters must align with carbon border adjustments like the EU CBAM (Carbon Border Adjustment Mechanism) and sustainable supply chain protocols.
ü Resilience and Risk Management
Sustainability is directly linked to risk mitigation. Companies that fail to decarbonize face reputational damage, financial losses, and legal action.
- Global Decarbonisation Pathways in Chemical Industry
The chemical sector worldwide is increasingly under pressure to decarbonize, as it is responsible for around 3–4% of total global CO₂ emissions and nearly 20% of industrial energy use. Different regions are adopting varied strategies, shaped by their economic structures, regulatory frameworks, and technological readiness.
1. European Union (EU)
- The EU chemical industry, led by Germany, France, and the Netherlands, is pioneering green chemistry, renewable energy integration, and hydrogen-based feedstocks.
- Initiatives like the EU Green Deal and the Carbon Border Adjustment Mechanism (CBAM) push companies to reduce carbon footprints across their value chains.
- Large players such as BASF are piloting electrified steam crackers, carbon capture and storage (CCS), and circular plastics to minimize emissions.
2. United States
- The U.S. chemical industry is leveraging the Inflation Reduction Act (IRA), which provides billions in incentives for clean hydrogen, carbon capture, and renewable energy.
- Companies like Dow Chemicals and ExxonMobil Chemicals are investing in low-carbon ethylene plants, large-scale CCUS projects, and advanced recycling of plastics.
- The focus is on technology scaling and partnerships with academia and startups for sustainable feedstocks.
3. China
- As the world’s largest producer and consumer of chemicals, China faces the dual challenge of growth and sustainability.
- The government has mandated energy efficiency improvements and is aggressively investing in green hydrogen, bio-based chemicals, and recycling infrastructure.
- Leading companies are focusing on process electrification and renewable integration, supported by state policies aligned with China’s 2060 carbon neutrality goal.
4. Japan and South Korea
- Japan is pushing green ammonia, hydrogen, and advanced recycling technologies, supported by strong R&D ecosystems.
- South Korea has launched its K-ETS (Emissions Trading Scheme), encouraging its chemical giants to adopt low-carbon pathways and circular economy practices.
5. India
- Companies such as Tata Chemicals, GACL, UPL, and Aarti Industries are making progress through renewable energy adoption, zero-liquid discharge, and green hydrogen pilots.
- However, challenges include capital costs, fragmented industry structures, and dependence on fossil fuels, making international collaboration vital.
While Europe and the U.S. lead in regulatory-driven innovation, China is scaling rapidly with state-backed investments, Japan and Korea are driving hydrogen-led R&D, and India is at an inflection point — balancing growth with sustainability. Together, these efforts reflect a global convergence toward decarbonization, though at varied speeds and scales.
- Pathways to Net Zeo: Strategic Priorities
Achieving net-zero emissions in the chemical sector is not about one silver bullet; it is a combination of innovation, circularity, and ecosystem transformation. Below are few mentioned areas where transition can leads to a substantial progress in emission reduction.
ü Energy Efficiency and Electrification
- Transitioning from fossil-fuel-based heating to electric boilersand heat pumps.
- Upgrading equipment efficiencyand process optimization through AI and IoT.
- Renewable Energy Adoption
- Onsite solar, wind, and biogas installations.
- Power Purchase Agreements (PPAs) with green energy providers.
- Use of Green Hydrogen as a feedstock and fuel — especially for ammonia, methanol, and refining sectors.
ü Circular Economy and Waste Valorization
- Recovery of solvents, acids, and by-products.
- Use of bio-based feedstocks instead of petrochemicals.
- Industrial symbiosis — sharing waste streams across clusters to reduce landfill and emissions.
ü Carbon Capture, Utilization and Storage (CCUS)
- Capturing CO₂ from flue gases and reusing it in urea production, enhanced oil recovery, or mineralization.
ü Sustainable Product Design
- Shifting towards green chemistry, biodegradable polymers, and low-VOC formulations.
- Reducing lifecycle impacts through Life Cycle Assessments (LCA) and Design for Environment (DfE)principles.
The transition to net-zero in the chemical industry is both urgent and achievable. However, it demands coordinated action:
- Cross-Sector Collaboration: Engage with academia, startups, and policymakers to nurture innovation ecosystems.
- Skill Development: Upskilling workforce in green chemistry, energy management, and LCA.
- Sustainable Finance: Leverage green bonds, carbon credits, and ESG funds to finance transformation.
- Transparent Reporting: Adopt robust ESG disclosure, internal carbon pricing, and science-based targets.
- A Greener formula for Chemical industry Growth
Chemical industry holds a dual responsibility — to power the country’s economic ambitions while safeguarding its environmental future. The net-zero journey may seems daunting, but it also presents an exceptional opportunity to reimagine the sector with sustainability at its core.
With the right mix of innovation, regulation, and leadership, the chemical sector can not only reduce emissions but become a net-positive force for the climate, economy, and society.
