For years, sustainability was a statement of intent. Companies published corporate responsibility reports with carefully selected data, with no framework requiring them to measure, verify, or compare anything. That model is over.
In 2026, sustainability has stopped being a voluntary narrative and become a complex, demanding, and legally binding regulatory framework. And what is changing is not just the volume of paperwork companies must file — the entire logic of how businesses are expected to manage their impact has shifted.
What Does the New Regulation Actually Require?
The CSRD: The New Standard for Sustainability Reporting
The central piece of the European framework is the CSRD (Corporate Sustainability Reporting Directive). This directive sets out which companies must report, when, and under what conditions — turning sustainability reporting into a far broader obligation than anything that came before.
The key shift is this: reports will no longer be voluntary. They will be mandatory, detailed, standardised, and comparable. And the information must be externally audited with the same methodological rigour applied to financial statements.
The ESRS: A Common Language for Sustainability
To ensure that data is genuinely comparable across companies and sectors, the CSRD relies on the ESRS (European Sustainability Reporting Standards). These standards set out structured requirements for reporting on climate change and environmental footprint, corporate governance and business ethics, and human rights across the value chain.
The practical implication is significant: it is no longer enough to state that a company «cares about the environment.» Businesses must demonstrate, with concrete data, a defined methodology, and independent verification, what real impact their operations actually have.
Which Companies Are Actually Affected?
This is where the picture has shifted most significantly in recent months. The so-called Omnibus I Package, approved in February 2026, revised the scope thresholds: the obligation to report under the CSRD now applies to companies with more than 1,000 employees and a turnover above 450 million euros. This represents an estimated 80% reduction compared to the companies originally in scope.
However, organisations that fail to adapt their internal processes in time will face regulatory, reputational, and financial risks. And the indirect impact on SMEs embedded in the supply chains of large groups is very real — their clients will demand ESG data to meet their own reporting obligations.
Due Diligence: Responsibility Beyond Your Own Operations
Alongside reporting, the other major regulatory lever is the CSDDD (Corporate Sustainability Due Diligence Directive). Due diligence obligations are now extending across value chains, requiring companies to demonstrate oversight of environmental and human rights risks beyond their direct operations.
This means that responsibility no longer stops at the factory gate. What happens with suppliers, subcontractors, and sourcing processes is now part of the compliance perimeter.
Why Waiting Is Not a Strategy
Organisations that continue to treat ESG as a compliance exercise risk falling behind. Those that approach it strategically gain clear advantages in the European market: stronger risk management, improved access to capital, and better alignment with investor and client expectations.
Investment funds managing over 40 trillion dollars in assets now integrate ESG factors into decision-making. Failing to disclose ESG risks can directly limit a company’s access to financing.
How to Prepare: Three Concrete Steps
The regulatory framework is demanding, but it is not unworkable. These are the real priorities:
- Materiality assessment. Identify which ESG issues are relevant to the business and its stakeholders, following the criteria set out in the ESRS.
- Data digitalisation. ESG reporting must be published in standardised digital formats, making this a technical exercise that requires involving technology teams from the outset.
- Internal governance. ESG can no longer be the sole responsibility of an isolated sustainability department. Senior management, finance, and operations must integrate it into everyday decision-making.
In 2026, the question is no longer whether to comply. The question is whether the company is building the real capabilities to do so — and to turn that compliance into a competitive advantage.
