The Sustainability Report (or Disclosure/Statement) is an essential platform that allows companies to evaluate, manage and monitor their impacts, risks and opportunities related to environmental, social and governance (ESG) factors.
Although it represents a fundamental communication tool towards stakeholders and the outside world, it is first and foremost a strategic planning document: a corporate compass that not only captures the company's non-financial performance but also outlines its future development trajectory and short-, medium- and long-term transition goals.
Regulatory Evolution: From obligation to uniform reporting
With the entry into force of the European Corporate Sustainability Reporting Directive (CSRD), sustainability reporting has changed its legal nature:
-
For companies subject to the obligation: The report loses its nature as a standalone document and becomes, to all intents and purposes, a mandatory and integral section of the Management Report within the financial statements. The detailed contents of this disclosure are dictated by the ESRS standards, which have been simplified over the years to reduce the administrative burden.
To verify which companies fall within the scope of the obligated subjects and to know the respective deadlines post-Omnibus I, please consult our dedicated page on the CSRD.
Non-Obligated Companies, SMEs and voluntary reporting
For companies that do not fall under legal obligations but choose or need to report on their sustainability due to market demands, the scenario offers several options.
The European Commission officially adopted (July 2026) a voluntary Delegated Regulation that absorbs the technical work previously known as the Voluntary Sustainability Reporting Standard for SMEs [VSME]. This new official European principle allows smaller enterprises to streamline and proportion their reporting burden, while simultaneously protecting them from excessive data requests from large clients within the supply chain.
However, the voluntary European standard is not the only path. For non-obligated companies operating in global markets or wishing to maintain an international positioning, the GRI Standards remain an authoritative and widely adopted reference option by numerous entities globally for preparing their sustainability reporting.
