India's commitment to achieving Net Zero emissions by 2070, articulated at COP26, necessitates a profound transformation across its primary economic sectors. The challenge is complex, requiring a delicate balance between sustained economic growth, energy security, and climate action. While significant strides have been made in renewable energy deployment, the decarbonisation of hard-to-abate sectors like heavy industry, transport, and agriculture presents unique technological, financial, and policy hurdles. Effective strategy hinges on integrated policy frameworks, technological innovation, and a just transition mechanism for affected communities.

The imperative to decarbonise is not merely an environmental one but is intrinsically linked to India's energy independence and long-term economic resilience. This transition involves a shift from a fossil fuel-dominated energy system to one underpinned by renewables, green hydrogen, and sustainable practices. The ongoing policy evolution aims to create an enabling ecosystem that can attract necessary investments, foster domestic manufacturing of green technologies, and build crucial infrastructure to support this monumental energy shift.

Institutional and Legal Framework for Decarbonisation

India's decarbonisation efforts are steered by a multi-pronged institutional and legal framework, reflecting the cross-sectoral nature of climate action. Key ministries, statutory bodies, and policy documents collectively drive the national agenda.

National Policy Architecture

• National Action Plan on Climate Change (NAPCC), 2008: Outlines eight national missions, including the National Solar Mission and National Mission for Enhanced Energy Efficiency (NMEEE), setting the foundational agenda for climate action.
• India's Nationally Determined Contributions (NDCs) – Revised 2022: Pledges to reduce emissions intensity by 45% by 2030 (from 2005 levels), achieve 50% cumulative electric power installed capacity from non-fossil sources by 2030, and promote sustainable lifestyles.
• Long-Term Low Carbon Development Strategy, 2070: Submitted to UNFCCC, outlining pathways for transitioning across sectors like power, transport, industry, and urban planning towards the Net Zero by 2070 goal.

Key Regulatory Bodies and Schemes

• Ministry of New and Renewable Energy (MNRE): Apex body for all renewable energy matters; oversees schemes like the Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan (PM-KUSUM) and the National Green Hydrogen Mission (NGHM), which targets 5 MMT of green hydrogen production capacity by 2030 with an outlay of ₹19,744 crore.
• Bureau of Energy Efficiency (BEE): Established under the Energy Conservation Act, 2001; implements the Perform, Achieve and Trade (PAT) scheme, a market-based mechanism to enhance energy efficiency in energy-intensive industries, covering 13 sectors and over 1,000 designated consumers.
• Ministry of Power: Formulates policies for power generation, transmission, and distribution; introduced the Green Energy Open Access Rules, 2022 to facilitate renewable energy procurement by large consumers and reduce grid integration barriers.
• NITI Aayog: India's premier think tank, responsible for formulating long-term strategic plans and monitoring climate and energy policies; its 'NDC-Transport Initiative for Asia' focuses on electric mobility.
• Ministry of Road Transport and Highways (MoRTH): Implements the FAME-II (Faster Adoption and Manufacturing of Electric Vehicles) scheme, with a budgetary outlay of ₹10,000 crore, to promote electric vehicle adoption across India.

Challenges in Sectoral Decarbonisation

While India’s decarbonisation targets are ambitious, achieving them requires overcoming significant technological, financial, and socio-economic obstacles.

Technological and Infrastructure Gaps

• Green Hydrogen Production Costs: Despite the NGHM, green hydrogen production remains significantly more expensive than grey hydrogen (estimated at $3-5/kg versus $1-2/kg), hindering its wide-scale adoption in industries like fertiliser, steel, and cement.
• Carbon Capture, Utilisation, and Storage (CCUS): Deployment is nascent in India, facing high capital costs and the absence of clear regulatory frameworks for geological storage. Current capacity is negligible compared to the emission volumes from hard-to-abate sectors.
• Grid Modernisation and Storage: Integrating large-scale intermittent renewable energy (RE) requires substantial investments in smart grid technologies, energy storage solutions (e.g., battery energy storage systems – BESS), and transmission infrastructure, which currently lag behind RE generation growth.

Financing and Investment Hurdles

• Investment Gap: NITI Aayog estimates India needs ~$10 trillion by 2070 for its net-zero transition, implying an annual investment far exceeding current flows, particularly for innovative green technologies.
• Risk Perception: High perceived risks for nascent green technologies and long payback periods deter private sector investment without robust policy certainty and financial de-risking mechanisms.
• Transition Finance for MSMEs: Small and Medium Enterprises, which form a significant part of India's industrial landscape, lack access to affordable green finance and technical expertise for decarbonisation.

Just Transition and Socio-Economic Impact

• Employment Displacement: A rapid shift away from coal-fired power and fossil fuel-intensive industries threatens approximately 4 million jobs directly or indirectly linked to the coal sector, necessitating comprehensive reskilling and economic diversification programs.
• Energy Affordability: Ensuring that the transition to cleaner energy does not disproportionately burden lower-income households and industries with higher energy costs, impacting competitiveness and social equity.

Comparative Decarbonisation Approaches: India vs. European Union

Comparing India's decarbonisation strategy with that of the European Union (EU) highlights different pathways shaped by economic structures, historical emissions, and developmental priorities.

Critical Evaluation of India's Decarbonisation Pathway

India's decarbonisation strategy, while ambitious, faces structural and coordination challenges that could impede its progress. The current policy architecture often relies on sector-specific mandates and incentive schemes, sometimes leading to fragmented implementation. A significant structural critique lies in the dual regulatory structure for certain aspects of energy and industrial policy, where central ministries set targets and policies, but state-level entities retain significant control over implementation, land acquisition, and local permitting. This can create implementation inconsistencies and slow down project execution, particularly for large-scale renewable energy and green infrastructure projects.

Furthermore, while market mechanisms like the PAT scheme exist, India has yet to implement a comprehensive, economy-wide carbon pricing mechanism that could provide a stronger and more consistent economic signal for decarbonisation across all sectors. This contrasts with many developed economies that increasingly rely on carbon taxes or robust cap-and-trade systems. The absence of a strong, unified carbon price risks perpetuating investment in carbon-intensive assets, thereby increasing the challenge of future stranded assets. The integration of climate risk into financial sector regulations, though initiated by RBI, also needs deeper institutionalisation to reorient capital flows towards green investments.

Structured Assessment
