Published August 4, 2025

  • Sustainability

Key takeaways

  • Wavestone has analyzed 35 CSRD-compliant sustainability reports from leading European companies across five major industries, looking at both quantitative and qualitative data, thematic maturity, and how sustainability is woven into overall management reports.
  • The findings reveal a wide range of approaches and maturity levels, not only across sectors, but also in the shared challenges organizations are facing.
  • Below, discover the key insights and hurdles to anticipate as you shape your next CSRD program.

*Corporate Sustainability Reporting Directive

A complex exercise, many projects in motion

Sustainability reports now make up between 20% and 50% of Universal Registration Document (URD) volumes. Behind these publications lies a significant amount of work undertaken by leading companies navigating CSRD requirements in this first year.

Most organizations found themselves launching several internal initiatives simultaneously: raising employee awareness and engagement, aligning efforts between parent companies and subsidiaries, reviewing sustainability policies, improving data reliability, and upgrading reporting tools. It was a demanding process, carried out under often tight deadlines.

This initial round has undeniably helped organizations establish a clear, structured baseline of their most material challenges, as well as a realistic view of the road ahead. However, it has rarely led to a complete rethinking of business models. Still, the groundwork is now laid for driving transformation in the years to come.

ESRS 2: a fresh opportunity to reframe your Sustainability strategy  

Even though the directive doesn’t require a specific format, the way information is presented plays a crucial role in making reports clear and offering real insight into how deeply organizations are embracing these new challenges. Most companies follow a hybrid approach: they stick closely to the ESRS 2 outline for general disclosures, environmental topics, and business conduct (G1), while taking a more flexible approach for social standards.

A structured plan, one that mirrors the standards closely, paired with user-friendly graphics, makes these reports easier to understand and compare. Climate-related disclosures (ESRS E1) set a strong precedent: they’re typically more thorough, quantified, and detailed, thanks to years of experience and established carbon frameworks.

As organizations gain experience in other areas, we’ll likely see greater consistency and discipline across the board.

Key ESRS Topics: what should be on your radar?  

Nearly every sustainability report now highlights clear climate goals. Most companies set short-term targets for 2030 and aim for Net Zero by 2050, usually aligned with the 1.5°C pathway and validated by SBTi.

A majority have formalized a climate transition plan. But few fully meet the standards. Financial planning and board-level oversight are often missing.

For climate adaptation, many companies are mapping physical risks to their assets and operations. Far fewer extend this assessment to their full value chain.

Risk analysis for transition is less commonly addressed. When companies do take it on, it often sparks a real shift in their business model. Yet, most of these assessments aren’t tied to clear, funded action plans woven into company strategy.

The EU green taxonomy has helped companies take that first step, identifying aligned CAPEX and starting to direct investments, even if efforts still focus mainly on climate mitigation.

More than compliance: what remains ahead to accelerate your sustainability transformation

CSRD is about more than just making non-financial data comparable. It’s a multi-year program designed to help you achieve your core goals: integrated performance and real business transformation.

Year one of CSRD felt tough—a new, detailed framework can be overwhelming. At the very least, ESRS gave everyone a shared language and logical structure.

CSRD also pushed organizations to step back and agree on the most important sustainability topics, using both impact and financial materiality perspectives. Many used CSRD as a springboard to bring together CSR, Finance, and Risk teams. It’s a way to make business units accountable, professionalize extra-financial reporting, and measure how far you’ve come and how much work remains.

Key action points include:

  • Clarifying resources for transition plans and building clear climate adaptation roadmaps
  • Structuring how you manage and preserve natural resources—water, pollution, biodiversity, and circular economy
  • Broadening your value chain focus, connecting with due diligence, and improving responsible sourcing criteria and levers
  • Aligning and operationalizing HR policies so they cover every entity and group, with measurable, tracked targets and outcomes

Feedback on CSRD program duration and sizing  

Varying timelines and team sizes for CSRD programs are shaped by four key factors:

  • Group and subsidiary coordination
  • Change management and employee engagement
  • Policy reviews and project depth
  • Reporting tool upgrades

Beyond these, project complexity, the standard’s detail, auditor expectations, and overall workload are often underestimated.

In short, most projects take at least 12 months. On average, CSRD programs last 15 months, with a typical staffing load of 6.9 FTEs (median 5.5 FTEs).

  •  15 months, it is the average duration of CSRD programs
  •  6,9 FTE, it is the average size of the core team of CSRD programs
