India’s Net-Zero Pathway: Ambition, Investment, and Reform

A $22.7 Trillion Transition: India’s Net-Zero Gamble

The figure is stark: achieving net-zero emissions by 2070 will cost India an estimated $22.7 trillion, according to NITI Aayog’s recent report, Scenarios Towards Viksit Bharat and Net Zero. Even after mobilising domestic resources, a $6.53 trillion funding gap remains—a gap filled with profound uncertainty over international climate finance commitments. For a nation aiming to become a developed economy by 2047, the report has painted both possibilities and overwhelming constraints.

Breaking Traditional Promises: An Inconvenient Reality

India’s net-zero ambition is not new, but what makes this report particularly disruptive is its alignment with development goals. Unlike earlier climate frameworks, where emissions were framed primarily as an environmental challenge, this roadmap integrates decarbonisation with economic transformation. The report sets unprecedented targets like scaling renewable energy capacity to 6,500–7,000 GW by 2070—nearly 25 times India’s current installed capacity of 319 GW.

However, such ambitions come with contradictions. The insistence on using coal as a transitional fuel raises concerns over whether India risks locking itself into fossil dependency. Furthermore, the report’s heavy reliance on international finance—as much as $6.53 trillion—replicates the pattern of unfulfilled past climate finance pledges under the Paris Agreement. Developed nations have barely met the existing $100 billion annual commitment stipulated for global climate action; this raises significant doubts about the feasibility of entrusting such large-scale transformation to external funding.

The Institutional Jigsaw: Legal and Policy Mechanics

The mechanics of this transition hinge heavily on institutional reforms. NITI Aayog’s recommendation for a dedicated National Green Finance Institution is one such proposed intervention. This body aims to mobilise and deploy capital at scale, de-risk projects, and channel both domestic and international private investments. Its rationale mirrors lessons from institutions like Germany’s KfW Development Bank, which has been central to mobilising climate funds through targeted lending.

In legal terms, much depends on changes to India’s regulatory and policy ecosystem. The Electricity Act, 2003, which governs power distribution and renewable energy procurement, will require amendments to enable deeper grid integration of renewables. Similarly, fiscal policy reforms could incentivise private investment, such as extending tax breaks under Section 80-IA for renewable energy projects. Yet, current institutional frameworks, such as the shallow corporate bond market (just 16% of GDP), act as bottlenecks to scaling finance effectively.

When Claims Collide with Reality

The financing gap isn't the only concern. The data raises more alarming questions. The report acknowledges that India currently channels only $135 billion annually into climate investments—an amount woefully below the required level. Meanwhile, residential electricity demand, driven largely by cooling systems, threatens to outpace efficiency gains. Cooling alone may become one of the primary drivers of energy consumption by 2047, putting additional pressure on power sector reforms.

Significantly, technology uncertainties loom over industrial decarbonisation. Hard-to-abate sectors depend predominantly on innovations like green hydrogen and carbon capture, utilisation, and storage (CCUS). These technologies, while promising, remain either prohibitively expensive or commercially undeveloped. Green hydrogen, for instance, continues to cost 5–6 times more than conventional fossil fuels—a gap that global subsidies alone cannot shrink unless market conditions evolve.

Critical Questions Left Unanswered

Beyond the numbers, the NITI Aayog’s report leaves crucial institutional challenges largely underexplored. First, long-term policy consistency is critical. India’s frequent policy reversals in the renewable energy sector—such as arbitrary tariff changes by state electricity regulators—have historically undermined investor sentiment. Banking heavily on international finance without addressing such domestic constraints may scale risks rather than reduce them.

Second, structural governance divides remain problematic. Decarbonisation requires tight coordination across sectors—transport, energy, and industry—an area where India’s bureaucratic silos have obstructed reform. For example, while India has made strides in electrifying transport, the integration of this sector with renewable energy generation lags behind. Moreover, the push for critical minerals like lithium shows signs of replicating India’s earlier dependence on crude oil imports—creating new vulnerabilities in supply chains without clear policy solutions.

Learning from South Korea’s Precision

One can point to South Korea’s 2018 Green New Deal as a case study. Faced with the challenge of decarbonising hard-to-abate industries, the Korean government implemented cap-and-trade mechanisms alongside targeted green subsidies—not merely promises of international finance. Within five years, its renewable energy production showed 147% growth, far outpacing India’s nearly stagnant performance in scaling domestic manufacturing of solar PV cells despite policy incentives.

India’s path differs, however, because of a vastly larger and more decentralised energy consumption base. Here, the comparison serves as a cautionary tale: precision in execution matters far more than ambition in planning.
