Indian businesses, particularly micro, small and medium enterprises (MSMEs) exporting to Europe, are facing rising sustainability compliance costs as the European Union tightens carbon regulations and disclosure requirements. Compliance and certification expenses for Indian exporters could range from $55,000 to $110,000, depending on manufacturing capacity, according to the latest edition of Uniqus Consultech’s Sustainability & Climate Pulse newsletter.
The report highlights growing pressure on smaller Indian manufacturers, with some exporters reporting a decline in inquiries from European buyers. Sourcing materials from larger producers to meet sustainability requirements can also increase procurement costs by 15% to 20% compared with purchases from secondary producers.
The cost pressures come as the European Union’s Carbon Border Adjustment Mechanism (CBAM) entered its definitive phase on January 1, 2026, bringing carbon-intensive imports under a more stringent emissions-reporting and compliance framework.
CBAM raises compliance stakes for Indian exporters
CBAM covers imports of iron and steel, aluminium, cement, fertilisers, electricity and hydrogen. The mechanism is designed to address carbon leakage by placing a carbon cost on certain imported goods based on their embedded emissions.
Although EU importers are legally responsible for purchasing and surrendering CBAM certificates, the financial implications could extend to exporters in countries such as India.
European buyers could pass on the additional costs through price negotiations, reduced sourcing volumes or decisions to shift procurement to suppliers with better emissions documentation and lower carbon footprints.
For Indian manufacturers, particularly MSMEs, the challenges extend beyond the direct cost of compliance. Obtaining verified emissions data from suppliers, establishing supply-chain traceability and accessing specialised certification expertise are emerging as significant operational hurdles.
The report emphasises the need for Indian exporters to strengthen greenhouse-gas accounting, emissions monitoring and internal data management systems to retain access to increasingly carbon-regulated international markets.
Uniqus Consultech Partner and Global Head of Sustainability & Climate Consulting Anu Chaudhary said sustainability compliance was increasingly becoming a determinant of competitiveness and market access for Indian businesses.
She said regulations such as CBAM would require exporters to improve visibility into emissions across their operations and supply chains, while stronger domestic assurance standards would raise expectations regarding the quality and credibility of sustainability disclosures.
Businesses investing early in reliable emissions data, traceability and internal controls would be better positioned to navigate the transition, she added.
ICAI introduces sustainability assurance framework
The tightening of international requirements coincides with India’s efforts to strengthen its domestic sustainability assurance framework.
The Institute of Chartered Accountants of India (ICAI) has issued the Standard on Sustainability Assurance (SSA) 5000, aligned with the international ISSA 5000 framework, with modifications suited to the Indian regulatory and reporting environment.
The standard will apply to financial years beginning on or after April 1, 2027.
It seeks to establish a consistent, principles-based framework for assuring sustainability information across different reporting frameworks. The move is expected to improve the credibility and comparability of corporate sustainability disclosures while providing greater clarity to reporting organisations and assurance providers.
For Indian companies seeking international customers and investors, the introduction of a domestic assurance framework could help improve the reliability of sustainability information and strengthen confidence in reported emissions data.
Carbon credit trading scheme expands domestic obligations
India’s domestic carbon market is also evolving, with the Ministry of Environment, Forest and Climate Change issuing amendments in September 2026 to update the entities covered under the Carbon Credit Trading Scheme (CCTS).
Companies brought under the scheme are required to meet prescribed emissions-intensity targets. Entities that outperform their targets can earn tradable carbon credit certificates, while those falling short must purchase certificates to meet their obligations.
The developing carbon market is expected to create financial incentives for companies to improve energy efficiency, adopt cleaner technologies and reduce emissions intensity.
NABKISAN raises ₹180 crore through WASH social bond
Sustainable finance is emerging as another important dimension of India’s transition. NABKISAN Finance Ltd, a subsidiary of the National Bank for Agriculture and Rural Development (NABARD), has raised ₹180 crore through what the report describes as India’s first social bond dedicated exclusively to water, sanitation and hygiene (WASH).
The five-year bond, listed on the National Stock Exchange on October 1, 2026, carries an annual coupon of 8.10%. It was oversubscribed 1.8 times and received AAA ratings with a stable outlook from CRISIL and CARE Ratings.
The proceeds will be deployed to finance water, sanitation and hygiene solutions, particularly in rural and underserved communities.
Sustainability moves beyond reporting compliance
The developments point to a growing convergence of international trade regulations, domestic emissions obligations and sustainable finance in India.
For exporters, the immediate challenge is the cost of establishing credible emissions measurement and verification systems, particularly for smaller manufacturers operating with limited financial and technical resources.
However, the implications extend beyond compliance expenditure. As European buyers increasingly factor carbon performance into sourcing decisions, the ability to demonstrate supply-chain transparency and verified emissions data could influence supplier selection and export competitiveness.
For Indian businesses, sustainability reporting and carbon management are consequently becoming strategic business requirements rather than merely regulatory obligations.
