What Is CSRD? Key Requirements for 2026 Compliance
2026 marks an important milestone in the Corporate Sustainability Reporting Directive (CSRD)journey, as many organisations across the European Union continue preparing for mandatory sustainability reporting. For many, this represents the first time they are required to measure and disclose environmental, social, and governance data in a structured and auditable way. The directive establishes sustainability reporting as a permanent component of corporate accountability, positioning non-financial information alongside financial data.
What is CSRD, and why was it introduced?
The Corporate Sustainability Reporting Directive (CSRD) is the European Union’s framework for sustainability reporting, replacing the previous Non-Financial Reporting Directive (NFRD). Its purpose is to create one consistent standard for how companies communicate their environmental, social, and governance performance. By introducing standard rules and a unified structure, CSRD aims to make sustainability information clear, comparable, and reliable across all EU member states.
The directive was introduced to address growing concerns about greenwashing and the lack of transparency in voluntary ESG disclosures. It aims to provide investors and stakeholders with accurate insights into how companies manage sustainability risks and opportunities, and to make sustainability data comparable across various industries and countries. CSRD also supports the EU’s broader climate and finance objectives, including theEuropean Green Deal and the Sustainable Finance Disclosure Regulation (SFDR), which together aim to shift business practices toward a more sustainable economy.
ESRS: The Framework Behind CSRD
At the core of CSRD are the European Sustainability Reporting Standards (ESRS), a set of detailed rules that define what companies must disclose in their sustainability reports. Developed and maintained by the European Financial Reporting Advisory Group (EFRAG), these standards establish a common framework for collecting, measuring, and presenting sustainability information.
The ESRS framework is not optional; it serves as the technical foundation of every CSRD report. It specifies which environmental, social, and governance topics must be addressed and how organisations should report on them to achieve compliance with the new sustainability reporting requirements.
Understanding the Double Materiality
A central concept of the Corporate Sustainability Reporting Directive is double materiality. It builds on existing sustainability practices and provides them with a structured framework within mandatory reporting. The idea requires companies to assess their activities from two perspectives. The first is financial materiality, which focuses on how environmental and social factors influence a company’s performance and economic outlook. The second is impact materiality, which examines how the company’s operations impact people, communities, and the environment.
By addressing both dimensions, double materiality helps organisations understand sustainability as a two-way relationship, connecting business outcomes with their broader impact. It outlines the information that must be included in a CSRD report and how companies should prioritise their sustainability topics.
Who Needs to Report Under CSRD After the Omnibus Revision?
The Corporate Sustainability Reporting Directive (CSRD) introduces sustainability reporting requirements in several phases. However, following the EU’s Sustainability Omnibus revision, the scope of companies required to report has been significantly narrowed.
Under the revised framework, sustainability reporting requirements primarily apply to:
Large companies with more than 1,000 employees and over €450 million in net annual turnover
Non-EU parent companies generating more than €450 million in EU turnover, subject to additional conditions related to EU subsidiaries or branches
This represents a major shift from the earlier CSRD scope, which included companies with 250+ employees. As a result, the number of companies falling into mandatory scope is expected to be significantly smaller than originally anticipated.
Companies below these thresholds may still choose to report voluntarily using simplified standards such as VSME, particularly when responding to supply-chain or stakeholder requirements.
How to Prepare for CSRD Under the Updated Timeline
Preparing for the Corporate Sustainability Reporting Directive (CSRD) requires structured coordination among finance, HR, sustainability, and supply chain teams. The process starts with clarity on material sustainability topics and builds from there.
Begin with a double materiality assessment to identify the sustainability issues that matter to both your business and your wider environment and society.
Define the scope of your report based on the assessment outcomes, and determine which topics, value chain elements, and disclosures will be applicable.
Conduct a gap analysis comparing your current reporting processes, data, and controls against CSRD requirements and the European Sustainability Reporting Standards (ESRS).
Establish clear KPIs and internal reporting processes, including the frequency of data collection, review, and publication.
Map all data sources and decide ownership, so each metric has a responsible owner, a verification process, and a traceable workflow.
Implement digital tools to automate data collection, validate inputs, manage workflows, and generate the final report in the correct technical format.

What to Include in a CSRD Report
A CSRD report consolidates detailed information about how a company operates, manages risks, and creates value sustainably. The reporting structure is based on the European Sustainability Reporting Standards (ESRS), which define the key disclosure categories every organisation must cover.
General disclosures: information about the company’s business model, strategy, governance structure, and risk management processes.
Environmental: data on climate change, pollution, water and marine resources, biodiversity, and resource use.
Social: disclosures covering the workforce, value chain workers, affected communities, and consumers.
Governance: transparency around business conduct, ethics, and anti-corruption practices.
All reported data must be consistent, traceable, and auditable. Achieving that level of reliability can be complex when working with spreadsheets and fragmented systems. This is where technology becomes a significant advantage; digital reporting platforms, such as the Terra ESG Platform, help companies automate data collection, maintain accuracy, and generate compliant sustainability reports with ease.
Penalties and Non-Compliance Risks
Failing to comply with the Corporate Sustainability Reporting Directive (CSRD) carries both financial and reputational consequences. Each EU member state determines its own penalties, but fines can reach up to €10 million or up to 5% or more of annual turnover, depending on the severity of non-compliance.
The risks go far beyond monetary penalties. Companies that submit incomplete or unverifiable disclosures may face audit rejection, lose investor confidence, and encounter greater challenges in accessing financing. Poor reporting can also damage credibility with stakeholders and business partners who increasingly expect transparent sustainability data.
The cost of inaction is greater than the cost of compliance, and companies that start preparing early protect their reputation, attract investment, and build long-term trust.
In Conclusion
CSRD is more than a legal requirement; it reflects a structural shift in how sustainability information is managed, governed, and trusted. While fewer companies may fall within scope under the updated Omnibus thresholds, those that do will face significantly higher expectations for data quality, traceability, and audit readiness.
Meeting these expectations with spreadsheets or fragmented systems is increasingly complex. As a result, many organisations are investing in dedicated ESG reporting software and sustainability reporting platforms to centralise ESG data, align disclosures with ESRS requirements, and maintain consistent governance across teams and value chains. The right ESG reporting platform not only supports compliance but also turns sustainability reporting into a repeatable, controlled business process.
Companies that move early gain more than regulatory certainty. By establishing structured ESG data foundations and using the right sustainability reporting software, they reduce compliance risk, increase transparency for investors and partners, and unlock more strategic insights from their sustainability data.
