ESG and Insurance: How Sustainability Mandates Are Reshaping Indian Underwriting

For much of the past decade, ESG considerations in insurance underwriting were dismissed by Indian market participants as a developed-world preoccupation, relevant to Lloyd's syndicates and European reinsurers, perhaps, but tangential to the realities of insuring Indian commercial risks. That era is definitively over. A convergence of regulatory mandates, reinsurance market pressure, and capital market expectations has pushed ESG from the periphery to the centre of underwriting decision-making in India's commercial insurance sector.

The catalyst has been regulatory rather than voluntary. SEBI's Business Responsibility and Sustainability Reporting (BRSR) framework, introduced in May 2021 and made mandatory for the top 1,000 listed companies by market capitalisation from FY 2022-23, created a structured disclosure regime covering environmental impact, social responsibility, and governance practices. The subsequent BRSR Core framework, announced in July 2023 and phased in for the top 150 listed companies first, added mandatory third-party assurance on a subset of ESG metrics. Greenhouse gas emissions (Scope 1 and 2), water consumption intensity, gender diversity, and gross wages paid to women, among others. These disclosures have given underwriters, for the first time, standardised and audited ESG data on a significant portion of India's commercial insurance buyer base.

Simultaneously, IRDAI has moved from passive observation to active guidance. The regulator's climate risk circular, building on the recommendations of its Sustainable Finance Working Group, has directed insurers to incorporate climate-related financial risks into their risk management frameworks. While IRDAI has not yet mandated ESG-specific underwriting criteria. Unlike the European Insurance and Occupational Pensions Authority (EIOPA), which requires Solvency II-regulated insurers to integrate sustainability risks; the direction of travel is unmistakable.

For Indian underwriters, the practical implication is clear: ESG factors are no longer optional qualitative overlays but are becoming quantifiable inputs to risk pricing, capacity allocation, and portfolio construction. The insurers who develop effective ESG integration frameworks today will be better positioned to manage the transition risks that are already materialising across carbon-intensive sectors of the Indian economy.

Understanding the BRSR framework is essential for Indian underwriters because it determines what ESG data is available, how reliable it is, and how it can be incorporated into risk assessment. The BRSR framework replaced the earlier Business Responsibility Report (BRR) mandated under SEBI's Listing Obligations and Disclosure Requirements (LODR) Regulations, 2015, and represents a quantum leap in disclosure granularity.

The BRSR is structured around nine principles derived from the National Guidelines on Responsible Business Conduct (NGRBC), covering topics from ethical governance and employee wellbeing to environmental stewardship and consumer protection. For underwriting purposes, the most directly relevant disclosures fall under Principle 6 (environmental protection and restoration) and Principle 7 (responsible policy advocacy). These sections require companies to disclose energy consumption and intensity, greenhouse gas emissions (Scope 1 and Scope 2, with Scope 3 encouraged), water withdrawal and discharge volumes, waste generation and disposal methods, and biodiversity impact assessments.

The BRSR Core framework layered mandatory third-party assurance on top of these disclosures for a subset of metrics. This assurance requirement (initially applying to the top 150 listed companies and progressively extending to the top 1,000) is what transforms BRSR data from self-reported narrative into underwriting-grade information. An assured Scope 1 emissions figure, for instance, can be directly correlated with environmental liability exposure and regulatory compliance risk under the Environment Protection Act, 1986, and the Air (Prevention and Control of Pollution) Act, 1981.

For D&O underwriters specifically, BRSR disclosures have become a critical input. A company's failure to comply with BRSR requirements, or material misstatements in its BRSR filings, creates director and officer liability exposure. SEBI's enforcement mechanisms include penalties under the LODR Regulations and, in cases of deliberate misrepresentation, proceedings under the SEBI Act, 1992. D&O underwriters are now incorporating BRSR compliance quality, measured by completeness of disclosures, presence of assured metrics, and year-over-year consistency, into their pricing models.

The supply chain dimension adds further complexity. The BRSR Core framework requires reporting companies to disclose ESG performance of their top value chain partners. As a result, even unlisted companies (which are not themselves subject to BRSR) are being evaluated on their ESG credentials by their listed customers. Underwriters insuring these supply chain participants must recognise that ESG performance gaps can translate into contract losses and business interruption risk.

IRDAI's approach to ESG integration in insurance has been evolutionary rather than revolutionary, reflecting the regulator's awareness that India's insurance sector, with a non-life penetration rate of approximately 1% of GDP, cannot absorb regulatory shocks that might further constrain capacity. Nevertheless, IRDAI's actions over the past three years have established a clear trajectory toward mandatory climate and sustainability risk integration.

The foundation was laid with IRDAI's participation in the Network for Greening the Financial System (NGFS) discussions and the subsequent formation of a Sustainable Finance Working Group. This working group's recommendations informed the climate risk circular that directed insurers to: assess climate-related financial risks (physical and transition risks) across their underwriting portfolios; develop scenario analysis capabilities for climate stress testing; integrate climate risk considerations into product development and pricing; and enhance disclosures on climate-related financial risks in line with the Task Force on Climate-related Financial Disclosures (TCFD) recommendations.

While the circular stopped short of prescribing specific underwriting actions, such as mandatory exclusions for fossil fuel projects or carbon-weighted pricing formulae, it created an expectation that insurers would demonstrate progress on climate risk integration during IRDAI's supervisory review processes. Insurers who fail to show meaningful progress risk regulatory observations and, ultimately, directions under IRDAI's supervisory powers.

India's commitments under the Paris Agreement add an international dimension. India's updated Nationally Determined Contribution (NDC), submitted in August 2022, commits to reducing the emissions intensity of GDP by 45% by 2030 (relative to 2005 levels), achieving 50% cumulative electric power installed capacity from non-fossil fuel sources by 2030, and reaching net-zero emissions by 2070. These commitments create a policy environment in which carbon-intensive industries face increasing regulatory risk. And that regulatory risk directly translates into underwriting risk.

IRDAI has also signalled interest in promoting green insurance products. The regulator's sandbox framework has been used by several insurers to pilot parametric weather insurance products, renewable energy equipment warranties, and carbon credit insurance — all products that sit at the intersection of insurance innovation and sustainability objectives. While these products remain niche, IRDAI's willingness to facilitate experimentation suggests that ESG-aligned product development will be a feature of the environment going forward.

For underwriters, the practical takeaway is that IRDAI expects demonstrable progress on climate risk integration, and the regulatory framework is likely to become more prescriptive as India's NDC targets approach their 2030 milestones.

The most tangible manifestation of ESG in Indian underwriting today is the emergence of sectoral pricing adjustments that reflect carbon intensity and transition risk. While no Indian insurer has publicly announced a carbon surcharge in the manner of some European markets, the effect is being achieved through risk-based pricing adjustments that incorporate environmental and regulatory compliance factors.

The power and energy sector illustrates this dynamic most clearly. Coal-fired thermal power plants (which account for approximately 55% of India's installed generation capacity) face a compounding set of ESG-related underwriting pressures. On the physical risk side, these plants face increased exposure to water scarcity (thermal plants are water-intensive, and several Indian coal plants have experienced forced shutdowns due to cooling water shortages), extreme heat events that reduce efficiency, and air quality regulations under the National Clean Air Programme (NCAP) that require expensive flue gas desulphurisation (FGD) retrofits. On the transition risk side, the Ministry of Environment, Forest and Climate Change (MoEFCC) emission norms, the proposed Carbon Credit Trading Scheme under the Energy Conservation (Amendment) Act, 2022, and the declining cost of renewable alternatives all threaten the long-term viability of coal generation assets.

Underwriters are responding by adjusting property and engineering insurance rates for coal-fired plants upward. Not through a labelled ESG surcharge, but through higher base rates that reflect the elevated physical risk, increased deductibles for pollution-related losses, and reduced coverage periods that require more frequent underwriting reviews. Reinsurance treaty renewals have amplified this effect: global reinsurers, many of whom have explicit coal underwriting restrictions or phase-out timelines, are reducing capacity for Indian coal risks, forcing cedants to retain more risk or pay higher retrocession rates.

The chemicals sector faces similar pressures. Companies manufacturing or handling substances listed under the Manufacture, Storage and Import of Hazardous Chemicals Rules, 1989, or subject to the Chemical Accidents (Emergency Planning, Preparedness and Response) Rules, 1996, have always attracted higher liability premiums. ESG considerations are adding a new dimension: underwriters now evaluate chemical companies' waste management practices, effluent treatment compliance (against the Central Pollution Control Board standards), and progress toward adopting less toxic alternatives. Companies with poor ESG profiles, multiple CPCB show-cause notices, unresolved pollution complaints, or high toxic release inventory, face capacity constraints and premium loadings that can exceed 30-40% above standard rates.

Conversely, sectors aligned with India's sustainability transition are beginning to see pricing benefits. Green building-certified commercial properties (rated under IGBC or GRIHA standards) demonstrate lower fire risk (due to better electrical systems and materials), improved water management (reducing water damage exposure), and stronger maintenance practices. All of which justify premium credits of 5-15% on property insurance programmes.

The concept of ESG-adjusted underwriting scores represents the most sophisticated integration of sustainability factors into the Indian underwriting process. While still in its early stages, several leading Indian insurers and reinsurers have begun developing proprietary scoring methodologies that overlay ESG metrics onto traditional risk assessment frameworks.

The fundamental challenge is translating qualitative ESG assessments into quantitative underwriting inputs. A traditional property underwriting score for an industrial risk might incorporate factors such as construction class, fire protection systems, loss history, business interruption exposure, and natural catastrophe exposure. An ESG-adjusted score adds dimensions such as the insured's carbon emissions trajectory (improving, stable, or deteriorating relative to sectoral benchmarks), regulatory compliance history with environmental authorities, water stress exposure at the insured's operating locations, governance quality indicators (board independence, audit committee effectiveness, related-party transaction controls), and social factors including workforce safety metrics and community relations.

The methodology must avoid two pitfalls. The first is ESG washing, applying superficial ESG labels without changing actual risk selection or pricing decisions. If an ESG score does not affect the rate, the terms, or the capacity offered, it adds process cost without underwriting value. The second pitfall is excessive penalisation of sectors that are essential to India's economy and energy security during the transition period. Indian underwriters cannot simply adopt European exclusion lists wholesale; India's coal sector, for instance, employs millions directly and indirectly, and its installed capacity will remain a system requirement until renewable alternatives and storage solutions achieve sufficient scale.

The emerging market practice among Indian insurers is a tiered approach. Risks are classified into three or four ESG tiers based on a composite score derived from BRSR disclosures (where available), publicly available environmental compliance data (from CPCB and State Pollution Control Boards), governance ratings from proxy advisory firms, and proprietary assessments conducted during the underwriting survey. Tier 1 risks (those with strong ESG profiles) receive preferential pricing, broader coverage terms, and priority access to capacity. Tier 3 or 4 risks, those with material ESG deficiencies, face premium loadings, restrictive terms (such as pollution exclusions or governance-related warranty clauses), or, in extreme cases, declination.

Sarvada's underwriting intelligence platform integrates ESG data from BRSR filings, environmental compliance databases, and governance assessments into a unified risk score, enabling underwriters to make ESG-informed decisions without manual data aggregation across multiple sources. This automation is critical: the volume of ESG data available for India's top 1,000 listed companies is substantial, and manual synthesis is neither scalable nor consistent.

The governance pillar of ESG has the most immediate and quantifiable impact on Indian insurance pricing, primarily through Directors and Officers (D&O) liability insurance. ESG-related governance failures, from BRSR misstatements to environmental regulatory violations attributable to board-level negligence, are creating a new category of insurable (and increasingly litigated) risk.

SEBI's enforcement of BRSR compliance creates direct D&O exposure. A company that files a materially inaccurate BRSR (whether through deliberate misrepresentation or negligent failure to implement adequate reporting systems) exposes its directors and officers to SEBI enforcement proceedings, shareholder derivative actions, and potential personal liability under the Companies Act, 2013 (Section 134, which requires directors to ensure the accuracy of annual report disclosures). D&O underwriters are now routinely reviewing BRSR filings during the underwriting process, and companies with incomplete, inconsistent, or unassured BRSR disclosures face D&O premium increases of 10-25%.

Greenwashing liability is an emerging risk that Indian D&O underwriters must price. Greenwashing, making misleading claims about a company's environmental practices or sustainability credentials, has attracted regulatory scrutiny globally, and India is following suit. The Advertising Standards Council of India (ASCI) updated its Code for Self-Regulation in Advertising to address environmental claims in 2024, and SEBI's emphasis on BRSR assurance is partly motivated by concerns about unsubstantiated ESG claims in annual reports and investor presentations. A company that markets itself as carbon-neutral or net-zero-committed without credible evidence faces exposure to consumer complaints under the Consumer Protection Act, 2019, SEBI enforcement under the LODR Regulations for misleading disclosures, and shareholder actions alleging inflation of company value through false sustainability claims.

The National Green Tribunal (NGT) adds another dimension. NGT orders directing corporate liability for environmental damage (such as orders requiring compensation for groundwater contamination, air pollution-related health impacts, or restoration of damaged ecosystems) can create personal liability exposure for directors and key managerial personnel under Sections 15 and 17 of the Environment Protection Act, 1986. D&O policies must cover defence costs and potential penalties arising from NGT proceedings, and underwriters are increasingly asking about the insured company's history of NGT cases and environmental compliance orders.

The social dimension of ESG also affects D&O pricing. Companies facing allegations of labour rights violations, workplace safety failures resulting in fatalities (particularly in manufacturing and construction), or supply chain human rights issues face heightened D&O scrutiny. Under the Companies Act, 2013 (Section 135), companies meeting the prescribed thresholds must spend at least 2% of average net profits on Corporate Social Responsibility (CSR) activities, and directors are personally responsible for ensuring compliance. Non-compliance with CSR obligations, or perfunctory compliance that does not meet the spirit of the mandate, is increasingly flagged in D&O underwriting reviews.

Transition risk (the financial risk arising from the shift to a lower-carbon economy) is the most strategically significant ESG factor for Indian insurance portfolios. Unlike physical climate risk, which manifests through increased frequency and severity of natural catastrophe losses, transition risk operates through policy changes, technology disruption, and market sentiment shifts that can impair asset values and business viability, often more abruptly than physical risk trajectories would suggest.

For Indian insurers, the fossil fuel-dependent portfolio concentration is material. India's coal, oil, and gas sectors, along with downstream industries such as steel (which consumed approximately 70 million tonnes of coking coal in FY 2024-25), cement (the third-largest CO2 emitting sector in India), and thermal power generation, represent a substantial share of commercial property, engineering, and liability premiums. A sudden or accelerated policy-driven transition. Triggered, for instance, by the operationalisation of India's Carbon Credit Trading Scheme or a tightening of MoEFCC emission norms ahead of the 2030 NDC deadline, could impair the insurability of these assets, create stranded asset exposures, and trigger correlated losses across multiple lines of business.

The stranded asset risk is particularly acute for coal-fired power plants. The Central Electricity Authority's (CEA) National Electricity Plan projects that no new coal capacity additions will be required after 2031-32, and existing plants below a certain efficiency threshold may face premature retirement as renewable energy plus storage becomes cost-competitive. An insurer with significant property and engineering exposure to coal plants faces the risk that these assets (currently insured at replacement cost) may have economic values that decline to scrap value over a compressed timeline. Business interruption coverage for coal plants also becomes questionable when the underlying revenue stream is threatened by energy transition dynamics.

Steel manufacturers face transition risk through the European Union's Carbon Border Adjustment Mechanism (CBAM), which entered its transitional phase in October 2023 and will require EU importers of steel, cement, aluminium, fertilisers, and other carbon-intensive products to purchase certificates corresponding to the carbon price that would have been paid had the goods been produced under the EU's Emissions Trading System. Indian steel exporters, who shipped approximately 6.7 million tonnes to the EU in FY 2023-24, face increased production costs or reduced export competitiveness, directly affecting their revenue projections and, consequently, their business interruption exposure calculations.

Prudent portfolio management requires Indian insurers to conduct transition risk scenario analysis across their commercial books. This involves mapping portfolio exposure to carbon-intensive sectors, modelling the impact of plausible transition scenarios (orderly transition, delayed transition, and disorderly transition) on insured asset values and business interruption exposures, and adjusting capital allocation and reinsurance purchasing accordingly. Insurers who concentrate capacity in transition-vulnerable sectors without adequate reinsurance protection or diversification face potential portfolio impairments that could test solvency margins.

The central tension in ESG-integrated underwriting is between the imperative to manage sustainability-related risks and the responsibility to maintain insurance availability for sectors that are essential to India's economic development and energy security during the transition period. Indian underwriters cannot simply replicate the exclusion-heavy approach adopted by some European and North American markets without exacerbating the protection gap in a market where non-life insurance penetration already lags global benchmarks.

This tension is not abstract. If Indian insurers restrict capacity for coal-fired power plants too aggressively, they risk forcing these assets into uninsured or underinsured status, which does not reduce the underlying risk but merely transfers it to the plant owners' balance sheets or, ultimately, to the public exchequer. India's coal plants will continue operating for decades as baseload capacity; the question for underwriters is whether to price and manage this risk responsibly or to cede it to less sophisticated risk bearers.

The pragmatic path forward involves several elements. First, engagement over exclusion: underwriters should use ESG assessments as a basis for dialogue with insureds, identifying specific risk improvement actions, such as FGD installation at thermal plants, effluent treatment upgrades at chemical facilities, or governance reforms at companies with weak board structures, that can justify improved coverage terms and pricing. This incentive-based approach aligns the insurer's risk management interests with the insured's transition pathway.

Second, transition-linked products: Indian insurers should develop insurance products that explicitly support the transition to a lower-carbon economy. Green building insurance with sustainability certification credits, renewable energy equipment performance warranties, carbon credit insurance for projects registered under the Gold Standard or Verified Carbon Standard, and parametric products tied to climate indices are all product categories where India's insurance market has room for innovation. IRDAI's regulatory sandbox provides a mechanism for testing these products without full regulatory compliance burden during the pilot phase.

Third, data infrastructure: the quality of ESG-integrated underwriting is only as good as the data it relies upon. Indian insurers need to invest in ESG data platforms that integrate BRSR disclosures, CPCB compliance records, SPCB consent orders, NGT proceedings, CSR expenditure data, and governance ratings into a unified underwriting information layer. Manual aggregation of these data sources is impractical at scale; technology-enabled solutions that ingest, normalise, and score ESG data in real time are essential.

Fourth, reinsurance alignment: Indian cedants must ensure that their ESG underwriting approach is aligned with their reinsurance treaty terms. Global reinsurers' ESG restrictions (particularly on coal and oil sands) can create coverage gaps if the cedant's direct underwriting portfolio includes risks that the treaty reinsurer excludes. Proactive dialogue with reinsurers about transition timelines and sector-specific approaches is critical to avoiding unpleasant surprises at treaty renewal.

The insurers who manage this transition successfully will be those who treat ESG not as a compliance burden but as an underwriting intelligence advantage (a richer, more forward-looking dataset that improves risk selection, pricing accuracy, and portfolio resilience. The alternative) ignoring ESG until regulatory or reinsurance pressure forces abrupt portfolio adjustments. Is both commercially and socially suboptimal.
