Pune – The most consequential effect of Indian ESG regulation is falling on companies the regulation does not cover. Listed firms are passing their disclosure requirements down to suppliers, and most of those suppliers are small businesses with no capacity to answer.
BRSR applies to the top listed entities. Their supply chains do not stop there, and questionnaires on emissions, workforce composition, labour practice and safety are moving through domestic supply networks to thousands of micro, small and medium enterprises.
The data does not exist to be reported
A typical supplier does not track Scope 1 and 2 emissions, hold workforce diversity data, or keep a safety incident register in any standard format. This is not evasion. The systems were never built, because nothing previously required them.
Such firms run lean, with owners handling operations, finance and compliance together. Asked for an emissions inventory, the realistic options are to guess, to pay a consultant, or to lose the customer.
Guessing is the worst outcome for everybody
When a supplier estimates to satisfy a questionnaire, the number enters the buyer Scope 3 inventory and eventually an assured disclosure, carrying an accuracy it never had.
This is the structural weakness in value chain reporting, and it is why SEBI softened the requirement rather than mandating it. The data quality problem sits at the far end of the chain where there is least capacity to solve it.
The export dimension is harder still
Suppliers exporting to Europe face the carbon border mechanism and due diligence rules that do not accommodate small firm capacity. A concluded India-European Union trade agreement improves market access while leaving those requirements intact.
Where the opportunity actually is
Suppliers that can evidence their numbers become preferred vendors, because a buyer needing assured Scope 3 data will pay for reliability. The competitive advantage goes to whoever builds the measurement capability first, and it is available cheaply while few have bothered.
