When the Transition Plan Becomes a Liability: BRSR Core, Directors' Climate Duties and the D&O Coverage Question for FY2026-27

For three reporting cycles, climate and ESG narrative in an Indian annual report was, in practice, soft. A clumsy sentence about emissions targets or a vague transition plan carried reputational consequences at worst. That softness is now gone for the largest issuers.

SEBI's BRSR Core framework runs a deliberate, escalating schedule. Reasonable assurance on the nine core ESG attributes applied to the top 150 listed companies by market capitalisation from FY2023-24, the top 250 from FY2024-25, the top 500 from FY2025-26, and reaches the top 1,000 from FY2026-27. Separately, value-chain ESG disclosure, voluntary for the top 250 in FY2025-26, becomes subject to mandatory assessment or assurance from FY2026-27 onwards.

Two features matter for risk. First, the standard is reasonable assurance, not the limited assurance most jurisdictions began with, including the EU under CSRD. Reasonable assurance is a positive opinion, closer to a financial audit than a review. Second, the assured numbers (Scope 1 and 2 emissions, energy and water intensity, waste, wages, diversity) now sit inside a regulated filing that SEBI can act on.

The practical effect is a change in legal character. A figure that is wrong is no longer just embarrassing. It is a misstatement in a document the regulator treats as material, prepared under board oversight, with a third-party assurer's name attached. That is the moment a transition plan stops being marketing and starts being a potential liability. For risk managers and the brokers who advise them, FY2026-27 is therefore the year the D&O coverage question on climate disclosure becomes concrete rather than theoretical.

Climate disclosure liability does not float free of named individuals. It attaches to directors through two well-established Indian channels, and the assurance requirement sharpens both.

The first is the statutory duty under Section 166 of the Companies Act, 2013, which requires a director to act in good faith and exercise due care, skill and diligence. A board that signs off a BRSR Core filing containing emissions or transition-plan claims it has not properly interrogated exposes its members to the argument that diligence was absent. A legal opinion circulated to Indian directors in recent years made this point bluntly: failing to treat foreseeable climate risk as a governance matter can itself be a breach of duty.

The second channel is misleading-disclosure liability. Directors and key managerial personnel can face personal consequences under the Companies Act for fraudulent or materially misleading statements in a regulated filing. SEBI introduced reasonable assurance into BRSR Core specifically to curb greenwashing, the practice of overstating environmental performance. So the regulator has both a motive and an instrument to pursue inaccurate climate claims.

The risk is not only the headline emissions number. It includes the transition plan narrative: targets a company says it is on track to meet, capex it claims is allocated to decarbonisation, and value-chain assertions it now has to support with assessment or assurance. A plan that reads as aspirational in a glossy report reads very differently once it is an assured representation a director has approved.

The top-1,000 cohort also overlaps heavily with the companies SEBI already requires to carry D&O cover for independent directors. So the population most exposed to assured climate disclosure is, conveniently, the population already buying D&O. The question is whether the policy they hold actually responds.

A D&O policy is built to defend directors against allegations of wrongful acts in their management capacity. Climate-disclosure exposure is, on its face, exactly that: an allegation that the board breached duty or approved a misleading statement. So far, so insurable. The gap appears in the detail of the wording.

Three clauses deserve scrutiny before FY2026-27 filings go out.

• Pollution and environmental exclusions. Many Indian D&O wordings carry a pollution exclusion drafted for physical contamination events. If broadly worded, an insurer may argue it bites on a climate-related securities or regulatory claim, even though the claim is about disclosure, not a spill. The fix is a carve-back so the exclusion applies only to bodily injury and property damage from actual pollutants, preserving cover for management liability arising from ESG disclosure.
• The regulatory investigation trigger. A SEBI inquiry into a BRSR Core misstatement may begin as an informal request, not a formal proceeding against a named individual. If the policy only funds defence costs once a director is formally a target, the most expensive early phase falls outside cover. Brokers should press for pre-claim inquiry costs and a low bar for what counts as an investigation.
• The bodily injury and property damage exclusion. Climate litigation can blend disclosure allegations with downstream damage claims. A blanket exclusion can be read to sweep in the disclosure piece. The defence-cost carve-back matters here too.

The strongest position is not a better policy bought after a claim. It is governance that an underwriter can see, paired with a wording matched to that governance. The two have to be built together.

Start with the board's own process. An underwriter pricing FY2026-27 D&O for a top-1,000 issuer will increasingly ask how the board oversees climate disclosure. Risk managers should be able to show:

1. A defined committee (often the risk or sustainability committee) with a written mandate over BRSR Core sign-off, not a once-a-year rubber stamp.
2. Evidence that emissions and transition-plan figures are challenged internally before the assurer arrives, with a documented trail of questions and management responses.
3. Clarity on the boundary of the assurer's engagement: what was assured, to what standard, and what the board independently verified. An assurer's reasonable-assurance opinion does not transfer the director's duty; it sits alongside it.
4. A consistency check between the BRSR Core filing, the management discussion in the annual report, investor presentations, and any sustainability-linked loan covenants. Inconsistent climate claims across documents are a classic source of a misleading-disclosure allegation.

With that governance documented, the broker has a bargaining position. A board that can demonstrate disciplined oversight is a better risk, and that should translate into the wording carve-backs above plus, where the exposure warrants it, a dedicated climate-disclosure endorsement and a higher defence-cost sub-limit for regulatory matters. The sequencing point is the practical one: arrange the governance review and the wording review on the same calendar as the FY2026-27 reporting cycle, not after the filing is lodged. Once a disclosure is public and potentially challenged, the negotiating position on both renewal terms and any uninsured-loss argument is far weaker.

Brokers explain coverage better when they can walk a board through the likely sequence of an actual claim. Here is the realistic arc for an Indian top-1,000 issuer.

The trigger is rarely a dramatic lawsuit on day one. More often it is a SEBI observation or an investor or activist group flagging a gap between a published transition plan and visible performance. That generates an information request. At this stage no director is formally accused, but counsel is already engaged and costs are accruing. Whether the policy funds this phase depends entirely on the investigation trigger discussed earlier.

If the matter escalates, two heads of exposure separate. One is the regulatory track: SEBI examining whether the assured disclosure was misleading and whether board oversight was adequate. The other is a securities track: shareholders alleging the climate claims influenced the stock and caused loss when reality emerged. Indian securities-claim culture is less developed than in the United States, but the structural ingredients (large public floats, mandatory disclosure, an active regulator) are present and the trend is one direction.

The most common surprise in claims of this type is not a denial on the merits. It is a dispute over allocation: how defence costs split between covered individual liability and uninsured entity penalties, and between the climate-disclosure allegation and any non-covered matter bundled with it. A pre-agreed allocation provision in the wording removes a fight at the worst possible moment.

For the risk manager, the lesson is that the value of the policy is decided long before the claim, in the wording and in the documented governance. By the time an information request lands, the room to improve terms has closed. The broker who has aligned cover to the transition plan in advance is the one whose client's defence is funded from the first letter rather than the first formal charge.

BRSR Core's FY2026-27 step does not stop at the listed entity's own boundary. The value-chain assessment or assurance requirement pushes climate-data obligations outward, and that creates exposure for companies that are not themselves in the top 1,000.

A large listed buyer now has to support value-chain ESG assertions. To do that, it leans on suppliers for emissions, energy and labour data. Many of those suppliers are unlisted manufacturers, logistics firms and processors with no assurance experience and no D&O programme calibrated for disclosure risk. When a supplier provides data that feeds an assured filing, two things follow. First, a contractual representation about that data, often backed by an indemnity to the buyer. Second, a potential professional-liability or management-liability exposure if the data turns out to be wrong and the buyer's filing is challenged.

This is where brokers serving the mid-market have a specific opening. The relevant covers are not only D&O for the supplier's own board but, in some cases, professional indemnity where the supplier is effectively certifying technical data, and clear contractual-liability analysis so the indemnity given to the buyer is understood and, where possible, insured.

Sectors feel this unevenly. The heaviest exposure sits with power and energy issuers, where emissions figures are central and transition plans are scrutinised hardest, with carbon-intensive manufacturing, and with real estate, where embodied-carbon and operational-energy claims are increasingly disclosed and increasingly testable. For these clients the message is consistent: the transition plan is now a document that can be litigated, the data behind it travels up the value chain, and the insurance response has to be arranged with that whole chain in view rather than at the parent entity alone.

The work splits cleanly between the board's house and the broker's file. Run both before the reporting cycle, not after.

On the governance side

• Confirm which BRSR Core attributes carry reasonable assurance this cycle and, for the top 250, what value-chain assessment or assurance now applies.
• Document the board committee's mandate over climate-disclosure sign-off and keep the trail of internal challenge to emissions and transition-plan figures.
• Reconcile the climate claims across the BRSR Core filing, annual report, investor decks and any sustainability-linked financing. Fix inconsistencies before publication.
• Map exactly where the assurer's opinion ends and the board's own representation begins. The duty does not transfer.

On the insurance side

• Pull the current D&O wording and read the pollution, bodily-injury and property-damage exclusions against a climate-disclosure scenario. Negotiate carve-backs that preserve management-liability cover.
• Press for a wide investigation trigger and pre-claim inquiry costs so the early, expensive phase of a SEBI request is funded.
• Seek a dedicated regulatory defence-cost sub-limit and a pre-agreed allocation clause to avoid an allocation fight at claim time.
• For value-chain suppliers, review contractual indemnities to the listed buyer and assess whether D&O, professional indemnity or contractual-liability cover responds.

The transition plan has crossed a line. It used to describe ambition. From FY2026-27, for the largest issuers, it is an assured, regulated representation that directors have approved and that a regulator can test. Treat it as the liability document it has become, and arrange the cover before, not after, someone decides to challenge it.
