Why Credible Transition Plans Matter for Financing India’s Net-Zero Transition

India’s pathway to net zero by 2070 is estimated to require USD 22.7 trillion in cumulative investment, according to NITI Aayog. Financing that transition will expose investors and lenders to real risk, from technologies that fail to scale as expected to carbon-intensive assets that turn stranded, and that risk is difficult to price without evidence that a company’s transition strategy is credible, funded and deliverable.

Indian companies are increasingly announcing net-zero ambitions and describing how they intend to get there, yet current disclosure mechanisms rarely give investors the evidence they need to judge these commitments. As transition finance and sustainability-linked funding grow in India’s capital markets, the gap between stated ambition and demonstrated substance is becoming a financing bottleneck rather than a reporting footnote.

Credible transition plans, not net-zero announcements alone, are what will determine how much of India’s climate financing need can actually be mobilised from private capital.

NITI Aayog’s 2026 scenarios study puts India’s cumulative net-zero investment requirement at USD 22.7 trillion by 2070, a figure that underlines both the scale of the opportunity for capital providers and the scale of the risk they take on by financing it. Technologies may not scale as expected, business models may need to shift, policy and carbon-price assumptions may change, and investments in carbon-intensive assets could become stranded, so investors need a way to assess whether a company is actually prepared to manage these risks.

India’s Business Responsibility and Sustainability Reporting (BRSR) framework, which sets disclosure requirements for the country’s largest listed companies, already requires reporting on many elements of a transition plan. What it does not yet do is specify what a complete transition plan should contain, and an IEEFA analysis of Indian companies’ transition disclosures found that the metrics most useful for spotting weak or unsubstantiated plans are among the least consistently reported.

Regulators have begun responding in parallel. SEBI’s ESG debt securities framework ties the credibility of ESG-labelled instruments to sustainability performance, RBI’s draft climate-related financial risk disclosure framework asks regulated entities to report on governance, strategy, risk management and metrics and targets, and IFSCA’s transition bonds framework places a credible entity-level transition plan at the centre of transition finance. Together, these signal that transition-plan quality is becoming a financing consideration, even without a single mandated format.

India’s net-zero transition will be financed by companies that can show their climate strategies are credible, funded and accountable, not simply by those with the most ambitious targets. Capital increasingly follows evidence, and the gap between disclosed ambition and demonstrated delivery is exactly where that capital hesitates.

Progressively building these six metrics into BRSR’s existing architecture, rather than creating an entirely new reporting framework, could improve the consistency, comparability and usefulness of India’s transition disclosures, and in turn strengthen BRSR’s role as the bridge between Indian companies and the capital the country’s transition needs.
