The Invisible Ledger: Decoding the Climate Impact of India’s Financial Powerhouses
The year 2024 arrived not with a warning, but with a reckoning. According to the Copernicus Climate Change Service (C3S), the world has officially overshot the 1.5°C warming threshold across a grueling twelve-month stretch. This isn’t just a statistic; it’s a signal that the era of climate procrastination has expired. While we fixate on the visible grime of tailpipes and the black plumes of smokestacks, the real architect of our planetary fever remains largely hidden from view. That force is Capital.
For the titans of finance, the front lines of the climate war aren’t found in LEED-certified offices or recycled paper initiatives. The real battle is etched into the Scope 3 Category 15 emissions—the carbon shadow cast by every single rupee they lend, invest, or underwrite. In India, this “invisible ledger” is finally being dragged into the light, and the view is increasingly uncomfortable.

The Weight of “Financed Emissions”
Unlike Scope 1 (the emissions a bank breathes out directly) or Scope 2 (the power it buys), Scope 3 Category 15 is the environmental DNA of a bank’s investment portfolio. These financed emissions are the true engine of environmental impact, typically making up more than 95% of a financial institution’s total carbon footprint.
“Financed emissions serve as a critical proxy for transition risk. As the world pivots toward a low-carbon economy, assets tied to high-carbon industries face the threat of becoming ‘stranded,’ turning a climate liability into a systemic financial risk that threatens the very stability of the balance sheet.”
The Indian Banking Trajectory: A Divergent Path
A seminal 2021 study, “Examining the Portfolio Carbon Footprint of the Indian Banking System,” offers a cold splash of reality. By dissecting data from 2010 to 2016, the research unmasked a troubling trend: the Weighted Average Carbon Intensity (WACI) of Indian bank loan portfolios surged by 9.4%, climbing from 332.5 to 363.7 tCO2e/US$ million.
This data isn’t just history; it reveals a structural decoupling failure that haunts the present. But the burden of this carbon debt isn’t distributed evenly:
- Public Sector Banks (PSBs): Here, financed emissions have hit a plateau. While they carry a heavy carbon load due to their role in powering national infrastructure and energy security, their growth in carbon intensity has actually begun to decelerate.
- Private Sector Banks: These institutions saw emissions nearly double during the study period.
It suggests a frantic expansion of private credit that prioritized immediate growth over long-term sustainability, funneling capital into sectors that haven’t yet broken their carbon addiction.
The PCAF Vanguard: Standardizing the Invisible
You cannot manage what you refuse to measure. Recognizing this, 12 Indian financial heavyweights officially joined the Partnership for Carbon Accounting Financials (PCAF) during the 2024-25 cycle. PCAF is the “gold standard” for figuring out the “attribution factor”—the exact slice of a borrower’s pollution that a bank must “own” based on the size of its checkbook.
Status of PCAF Adoption & Disclosure in India (2024-25)
| Institution Type | Name of Institution | Disclosure Status |
|---|---|---|
| Public Sector | State Bank of India (SBI), Bank of Baroda, Indian Bank, IOB, UCO Bank, Union Bank | No Full Disclosure |
| Public Sector | Punjab National Bank (PNB) | Full Disclosure (Baseline Established) |
| Private Sector | IDFC FIRST Bank, YES BANK, L&T Finance | Partial / Pending Disclosure |
| Specialized/Impact | Caspian Impact Investments, ESAF Small Finance Bank | Full Disclosure (Caspian) |
Signing a pledge is one thing; showing the receipts is another. A massive transparency gap still looms over the industry. While names are being added to the PCAF roster, only PNB and Caspian Impact Investments have had the courage to publish granular disclosures. For most of the sector, the carbon buried in the loan book remains a “known unknown.”
The Paradox of Green Finance vs. Coal Dependency
Indian banks are currently attempting a difficult high-wire act: fuelling the future while remaining tethered to the past. On one hand, we see genuine momentum. There are discounted loans for Electric Vehicles (EVs) and the aggressive launch of ESG-linked bonds. The State Bank of India (SBI), for example, has successfully moved climate bonds worth $800 million and launched the Neev Fund II, focusing on climate-positive SMEs.
But look closer at the “Brown Ledger.” During the 2023-24 fiscal year, roughly INR 25,945 crore was funneled into loans and underwriting for ten of India’s most prominent coal-linked conglomerates.
Key Coal Financing Figures (2023-24):
- Jefferies Financial Group: INR 16,784 Crore (Acting as a primary global intermediary and underwriter for Indian coal-heavy conglomerates).
- State Bank of India: INR 1,991 Crore
- Kotak Mahindra Bank: INR 1,495 Crore
- Punjab National Bank: INR 418 Crore
The presence of Jefferies, a US-based giant, adds a layer of irony: global capital markets are often the ones underwriting Indian coal expansion, even as domestic banks start to tighten their belts. For a behemoth like SBI, coal might be a shrinking slice of its multi-trillion rupee pie, but the sheer volume is still large enough to dictate the nation’s atmospheric future.
Regulatory Winds of Change: RBI and SEBI
The days of “voluntary” climate action are dying. The Reserve Bank of India (RBI) has stepped up its game, dropping a Draft Disclosure Framework on Climate-related Financial Risks in early 2024. This isn’t just paperwork; it aligns with Basel principles, meaning climate risk will soon dictate how much capital a bank must hold.
At the same time, SEBI’s new Framework for ESG Debt Securities is cleaning up the bond market. By setting higher bars for sustainability-linked instruments, SEBI is making “greenwashing” much harder to pull off, ensuring Indian ESG assets can actually stand up to international scrutiny.
The “Silicon Bottleneck” of Data
The wall most Indian financial institutions (FIs) hit is the “data vacuum.” To calculate Scope 3 emissions, you need data from thousands of borrowers. Many of these are MSMEs who don’t have the tools to track their own footprint, let alone report it.
To fix this, a new wave of homegrown Indian climate-tech innovators, like Sprih and ESG.ai, is stepping in. They use AI and sector-specific proxies to bridge the gaps where hard data is missing, acting as the “digital glue” that allows banks to finally see their own impact.
The Urgency of the “Slow” Transition
The adoption of PCAF and the surge in green bonds are good signs, but the velocity of action is lagging behind the physics of the planet. The 1.5°C breach tells us the luxury of a slow transition is gone. For India’s financial system, relying on polite disclosures and gradual shifts won’t be enough to stave off the systemic shocks of extreme weather or global trade penalties like the EU’s Carbon Border Adjustment Mechanism.
“The transition to a low-carbon economy is no longer an ethical choice; it is a fiduciary mandate. Banks that fail to aggressively decarbonize their portfolios today are essentially underwriting their own future insolvency.”
To move faster, experts are calling for mandatory climate stress testing and a rock-solid Green Taxonomy. We need to ensure that capital isn’t just moving—it’s moving to the right places, without being siphoned off by “transition-washing.”
Summary: The Financial Climate Mandate
“• Financed emissions represent the overwhelming majority of a bank’s climate footprint, creating systemic risks that far outweigh operational energy use. • While 12 Indian institutions have joined the PCAF, a massive transparency gap remains, with few providing full, audited carbon disclosures. • Evolving RBI and SEBI regulations are transforming climate reporting into a mandatory fiduciary duty essential for long-term financial stability.”
