CSRD Reporting Requirements in 2025: What Companies Must Know to Stay Compliant

What Is the CSRD and Why Does It Matter?

The Corporate Sustainability Reporting Directive (CSRD) represents the most significant overhaul of sustainability disclosure rules in the European Union's history. Adopted by the European Commission and effective from January 2024, the CSRD replaces the older Non-Financial Reporting Directive (NFRD) and dramatically expands the number of companies required to report on their environmental, social, and governance (ESG) performance.

Understanding CSRD reporting requirements is no longer optional for companies operating in or with the EU. The directive introduces stringent new standards, mandatory third-party assurance, and digital tagging of sustainability information. For many organizations, the gap between current reporting practices and CSRD compliance is substantial — and closing that gap requires deliberate, well-planned action.

If your company is preparing for CSRD compliance, tools like the Carbon Emission Report platform can help streamline carbon data collection and generate audit-ready reports aligned with the European Sustainability Reporting Standards (ESRS).

Who Must Comply With the CSRD?

One of the most critical aspects of the CSRD reporting requirements is the expanded scope of applicability. Under the old NFRD, only about 11,700 companies were subject to sustainability reporting obligations. The CSRD increases this number to approximately 50,000 companies across the EU and beyond.

EU-Based Companies

The CSRD applies to large EU companies that meet at least two of the following three criteria:

• 250 or more employees (down from 500 under the NFRD)
• EUR 50 million or more in turnover
• EUR 25 million or more in total assets

Listed small and medium-sized enterprises (SMEs) are also within scope, though they benefit from a longer transition period and can opt out until 2028.

Non-EU Companies

Here is where the CSRD reporting requirements become truly global in reach. Non-EU companies generating more than EUR 150 million in net revenue in the EU over two consecutive years, and that have at least one EU subsidiary or branch, must also comply. This means thousands of American, Asian, and other international companies will need to produce sustainability reports that meet EU standards.

Phased Implementation Timeline

The CSRD is being rolled out in waves:

• FY 2024: Companies already subject to the NFRD (approximately 11,700 large public-interest entities)
• FY 2025: Other large EU companies meeting two of the three size criteria
• FY 2026: Listed SMEs and non-EU companies meeting the revenue threshold
• FY 2028: Non-EU companies with significant EU revenue and a local presence

Understanding which wave your company falls into is the first step in building a realistic compliance roadmap.

Understanding the European Sustainability Reporting Standards (ESRS)

At the heart of CSRD reporting requirements are the European Sustainability Reporting Standards, developed by EFRAG (the European Financial Reporting Advisory Group). These standards define exactly what information companies must disclose and how it should be structured.

The ESRS Structure

The ESRS framework consists of 12 standards organized into four categories:

1. Cross-cutting standards (ESRS 1 and ESRS 2): Define general principles and mandatory disclosure points applicable to all companies
2. Environmental standards (ESRS E1 through E5): Cover climate change, pollution, water and marine resources, biodiversity and ecosystems, and resource use and circular economy
3. Social standards (ESRS S1 through S4): Address the company's own workforce, workers in the value chain, affected communities, and consumers and end-users
4. Governance standards (ESRS G1): Cover business conduct

Materiality Assessment: The Double Materiality Approach

A cornerstone of CSRD reporting requirements is the concept of double materiality. Unlike traditional financial reporting, which focuses solely on how sustainability issues affect the company's financial performance (financial materiality), the CSRD requires companies to also consider how their activities impact the environment and society (impact materiality).

This dual lens means companies must:

• Identify sustainability matters that are financially material to their business
• Assess their positive and negative impacts on people and the environment
• Report on both dimensions in an integrated manner

Conducting a robust double materiality assessment is often the most resource-intensive part of CSRD preparation. The Carbon Emission Report tool provides frameworks to help companies systematically evaluate their environmental impacts and prioritize reporting areas.

Key CSRD Reporting Requirements You Must Address

Mandatory Disclosure Points

Under ESRS 2, every reporting company must disclose information across several mandatory areas, regardless of the outcome of their materiality assessment:

• Governance: How the company's governance body oversees sustainability matters, including the skills and expertise of board members
• Strategy: The company's sustainability-related risks and opportunities, their impact on the business model and strategy, and the resilience of the strategy under different climate scenarios
• Impact, Risk, and Opportunity Management: How the company identifies, assesses, and manages sustainability-related impacts, risks, and opportunities through its due diligence process
• Metrics and Targets: Quantitative and qualitative information about performance against sustainability targets, including transition plans

Transition Plans

Companies must disclose their transition plans for climate change mitigation, aligned with the Paris Agreement's goal of limiting global warming to 1.5 degrees Celsius. This includes:

• Interim milestones and greenhouse gas emission reduction targets
• Capital expenditure plans supporting the transition
• Assumptions about how the company's business model will evolve
• Dependencies on carbon removals or offsets

Value Chain Reporting

The CSRD requires companies to report on sustainability matters across their entire value chain, not just their own operations. This means collecting data from suppliers, customers, and other business partners. The complexity of value chain reporting is one of the most challenging aspects of CSRD compliance.

Digital Taxonomy (XBRL Tagging)

All CSRD reports must be prepared in a machine-readable digital format using XBRL (eXtensible Business Reporting Language) taxonomy. This requirement enables regulators, investors, and other stakeholders to compare sustainability data across companies and sectors systematically.

How to Prepare for CSRD Compliance

Step 1: Conduct a Gap Analysis

Begin by comparing your current sustainability reporting practices against the ESRS requirements. Identify areas where you already have robust data and processes, and areas where significant work is needed.

Step 2: Perform a Double Materiality Assessment

Engage stakeholders — including employees, investors, customers, suppliers, and community representatives — to identify which sustainability matters are most material from both the financial and impact perspectives.

Step 3: Build Data Collection Infrastructure

CSRD reporting requirements demand granular, auditable data across environmental, social, and governance dimensions. Invest in tools and processes that can:

• Automate data collection from across your operations and value chain
• Ensure data quality and traceability
• Generate reports aligned with the ESRS structure
• Support the XBRL digital taxonomy format

Platforms like Carbon Emission Report can accelerate this process by providing pre-built templates for environmental data collection, automated emission calculations, and exportable reports designed to support CSRD compliance.

Step 4: Establish Governance and Internal Controls

Sustainability reporting under the CSRD must meet the same level of rigor as financial reporting. This means:

• Assigning clear ownership and accountability for sustainability data
• Implementing internal controls and validation processes
• Training finance and sustainability teams on the new requirements
• Engaging auditors early to understand assurance expectations

Step 5: Prepare for Limited Assurance

Starting in 2024, CSRD reports must undergo limited assurance by a statutory auditor or independent assurance services provider. By 2028, the expectation moves toward reasonable assurance — a much higher standard that requires more robust evidence and controls.

Common Challenges in Meeting CSRD Reporting Requirements

Data Availability and Quality

Many companies struggle with incomplete or unreliable sustainability data, particularly from their value chain. Building robust data collection processes takes time, and the quality of your CSRD report is only as good as the data behind it.

Cross-Functional Coordination

CSRD compliance is not just a sustainability team responsibility. It requires close collaboration between finance, legal, operations, procurement, human resources, and IT departments. Establishing effective cross-functional governance is essential.

Interpreting the Standards

The ESRS are detailed and complex, spanning thousands of pages of guidance. Many companies find it challenging to interpret how the standards apply to their specific industry and business model.

Keeping Pace With Regulatory Changes

The CSRD framework continues to evolve. The European Commission has already adopted sector-specific standards and may issue additional guidance. Companies must build agility into their compliance processes to adapt to changing requirements.

The Cost of Non-Compliance

Failing to meet CSRD reporting requirements carries significant consequences:

• Financial penalties: EU member states are required to establish dissuasive penalties for non-compliance, which can include fines proportional to the company's turnover
• Reputational damage: Public sustainability reports are scrutinized by investors, NGOs, media, and the public. Incomplete or inaccurate reporting can erode trust and damage brand value
• Investor skepticism: Institutional investors increasingly use sustainability data to inform capital allocation decisions. Non-compliance or poor-quality reporting may lead to higher capital costs or reduced investment interest
• Competitive disadvantage: Companies that comply effectively can differentiate themselves in the market, attract sustainability-conscious customers and talent, and build stronger stakeholder relationships

Sector-Specific Considerations

The ESRS include sector-specific standards that apply additional disclosure requirements based on a company's industry. For example:

• Agriculture and farming companies face detailed biodiversity and land-use reporting requirements
• Mining and metals companies must address water management, waste, and community impacts
• Financial institutions have specific requirements around financed emissions and sustainable finance disclosures
• Technology companies must address data privacy, digital inclusion, and energy consumption of data centers

Understanding the sector-specific requirements that apply to your business is critical for building an accurate compliance roadmap.

Building a Long-Term Sustainability Reporting Strategy

CSRD compliance should not be viewed as a one-time checkbox exercise. The most successful companies treat it as an opportunity to:

• Improve operational efficiency by identifying waste and resource optimization opportunities
• Strengthen risk management by systematically assessing environmental and social risks
• Enhance stakeholder relationships through transparent, credible reporting
• Drive innovation by using sustainability insights to inform product development and business strategy
• Attract capital by meeting the growing demand from investors for high-quality sustainability data

Conclusion: Your Next Steps for CSRD Compliance

The CSRD reporting requirements represent a fundamental shift in how companies communicate their sustainability performance. With the first reporting deadlines already in effect and the scope expanding rapidly, organizations must act now to build the capabilities needed for compliance.

Start by assessing your current readiness, conducting a double materiality assessment, and investing in the data infrastructure needed to produce high-quality, auditable sustainability reports. The companies that approach CSRD compliance strategically — rather than as a mere compliance exercise — will be best positioned to thrive in an increasingly sustainability-conscious business environment.
