Regulatory changes in ESG reporting are entering a decisive phase, shifting the framework from fragmented, largely voluntary disclosures toward a structured, mandatory, and increasingly audited system. The developments highlighted in the Serbian context reflect a broader European transition that is already reshaping capital allocation, corporate governance, and access to financing.
At the center of this shift is the European Union’s Corporate Sustainability Reporting Directive (CSRD), which significantly expands the scope and depth of ESG disclosures. The directive increases the number of companies required to report to roughly 50,000 entities across Europe, introducing standardized, comparable, and far more detailed reporting obligations.
Unlike earlier frameworks, ESG reporting is no longer treated as a supplementary narrative. It is becoming structurally embedded into financial reporting systems, with requirements covering environmental impact, social practices, governance structures, risk exposure, and forward-looking strategy.
From voluntary narratives to standardised data architecture
One of the most important regulatory changes is the transition toward European Sustainability Reporting Standards (ESRS), which operationalize CSRD requirements. These standards introduce a unified reporting architecture based on principles such as double materiality—requiring companies to disclose both how ESG factors affect their financial performance and how their operations impact the environment and society.
This marks a clear departure from earlier ESG approaches, where companies could selectively disclose information. Under ESRS, reporting becomes structured, comparable, and audit-ready, aligning ESG disclosures with the rigor of financial statements.
At the same time, regulators have begun to simplify certain elements of the framework to reduce administrative burden. Adjustments introduced in 2026 aim to improve readability, reduce duplication, and focus reporting on material issues, while maintaining investor-relevant transparency.
Verification and audit: ESG becomes a controlled function
A critical regulatory evolution is the move toward mandatory verification (assurance) of ESG data.
Companies are increasingly required not only to disclose ESG metrics but to ensure that these data points are traceable, documented, and verifiable, similar to financial audits. This introduces a new operational layer inside companies, requiring:
• Structured data collection systems
• Internal controls and documentation
• Third-party verification processes
By 2026, even companies outside the formal regulatory scope—particularly those integrated into EU supply chains—are facing pressure to provide auditable ESG data, especially when participating in tenders or working with European clients.
This effectively transforms ESG reporting from a communications exercise into a compliance and risk management function.
Serbia: Regulatory lag, market-driven acceleration
Serbia formally remains outside the EU regulatory framework, but in practice, it is already operating within its gravitational pull.
Current domestic regulations require non-financial reporting primarily for large entities with more than 500 employees, with relatively limited structure compared to EU standards.
However, this gap is narrowing rapidly.
Serbia is moving toward adoption of ESRS-aligned standards, with expectations that full alignment could occur by the end of 2026.
More importantly, market forces are accelerating this transition faster than legislation:
• EU buyers and supply chains demand ESG-compliant reporting
• Banks integrate ESG into credit risk assessments
• Investors require standardized disclosures for capital allocation
This creates a de facto regulatory environment where Serbian companies must comply with EU-level ESG expectations even before formal legal transposition.
Cost and complexity: A new barrier to entry
The regulatory tightening comes with a clear cost dimension.
For large corporations, ESG integration requires building internal reporting systems, hiring specialists, and implementing digital tracking tools. For small and medium enterprises, the burden is even more pronounced, as ESG compliance introduces administrative complexity and additional operational costs.
This dynamic is already influencing market structure. Companies that can absorb ESG compliance costs gain easier access to financing and international markets, while smaller firms risk exclusion from supply chains unless they adapt.
At the same time, ESG reporting is becoming directly linked to financing conditions. Banks increasingly evaluate environmental and social risk exposure when issuing loans, effectively using ESG as a credit filter.
Strategic shift: ESG as financial infrastructure
The cumulative effect of these regulatory changes is a fundamental repositioning of ESG.
It is no longer a reputational layer but a core financial and operational infrastructure, influencing:
• Cost of capital
• Access to EU markets
• Supplier eligibility
• Valuation and investor perception
In this context, ESG reporting is converging with financial reporting into a single integrated disclosure system.
For Serbia, this transition represents both a constraint and an opportunity. While regulatory alignment imposes short-term compliance costs, it also enables domestic companies to position themselves within EU-aligned industrial and financial ecosystems, particularly in sectors such as energy, manufacturing, and export-driven industries.
The direction is clear: ESG reporting is moving toward mandatory, standardized, verified, and capital-linked disclosure, with Serbia already embedded in that trajectory through market integration—even before full regulatory adoption.
