Can a CSRD expert temporarily join our internal sustainability team?

Yes. An interim CSRD specialist works inside your team, joins your meetings and uses your systems, so the knowledge stays with you. Companies do this to run a reporting cycle, cover parental leave or prepare for assurance. For a bounded task, such as one ESRS topic or reviewing your drafts, a project scope is enough.

Yes, a CSRD expert can absolutely join your internal sustainability team on a temporary basis. Many organizations bring in an interim CSRD specialist to handle reporting cycles, close knowledge gaps, or lead a specific disclosure project without committing to a permanent hire. This is a practical, increasingly common approach as CSRD obligations continue to evolve.

The regulatory landscape shifted significantly in 2026, with the Omnibus I directive raising the threshold to more than 1,000 employees and a net turnover above 450 million euros. Even so, the companies that remain in scope face real complexity, and many teams simply don’t have the in-house expertise to manage it alone. The sections below answer the most common questions organizations ask before bringing in temporary CSRD support — starting with what that support actually looks like in practice.

What does a CSRD expert actually do inside a company?

A CSRD expert embedded in your team works on the practical execution of your sustainability reporting obligations under the Corporate Sustainability Reporting Directive. Their core focus is ensuring your company produces compliant, accurate disclosures according to the European Sustainability Reporting Standards (ESRS). Day-to-day, this means translating regulatory requirements into internal processes your team can reliably follow and sustain.

More specifically, a CSRD reporting specialist typically handles tasks such as conducting or overseeing the double materiality assessment, mapping which ESRS topics apply to your business, coordinating data collection across departments, and drafting the sustainability statement that forms part of your management report. They also work closely with finance, legal, and operations teams to ensure the information gathered is consistent, traceable, and audit-ready. In practice, this often means serving as the connective tissue between regulatory requirements and the day-to-day realities of your internal data flows — identifying gaps in existing processes, establishing clear data ownership across departments, and building documentation trails that will withstand scrutiny from an external assurance provider.

A skilled CSRD expert will also assess how your reporting boundaries are defined, verify that your materiality conclusions are defensible under ESRS methodology, and support senior leadership in understanding the strategic implications of your disclosures. This includes preparing briefing materials, contributing to board-level reporting, and flagging any areas where your sustainability statement may be exposed to challenge during assurance review.

It is worth noting that CSRD experts represent a distinct specialization within sustainability. They differ from, for example, a Scope 3 emissions consultant or a B Corp advisor — a CSRD specialist’s expertise centers on disclosure frameworks, regulatory compliance, and the ESRS structure rather than on broader sustainability strategy or emissions reduction programs. Understanding that distinction also helps clarify how this kind of hire differs from the external consulting model many organizations default to first.

How does hiring a temporary CSRD expert differ from using a consultant?

A temporary CSRD expert joins your team and works from the inside, while a traditional consultant typically operates externally and delivers a defined product. The distinction is more significant than it may initially appear. An interim sustainability expert becomes part of your day-to-day operations, attends your meetings, works with your tools, and builds institutional knowledge that remains with your team even after they leave.

A consulting firm, by contrast, generally assigns a team to your project, runs its own process, and hands over a report or framework at the end. That model can work well for discrete, well-defined deliverables. However, when you need someone who genuinely understands your data, your internal dynamics, and the practical challenge of securing cross-functional alignment, an embedded interim specialist tends to be considerably more effective.

There is also a meaningful cost difference. Traditional consultancies carry overhead, multiple layers of account management, and extended onboarding processes built into their model. An independent CSRD freelancer working as part of your team removes those layers, giving you focused expertise without the structural complexity that slows delivery. Once you understand the value of that model, the natural next question is what qualifications to look for when choosing the right person.

What qualifications should a temporary CSRD expert have?

A qualified interim CSRD specialist should have hands-on experience with the ESRS framework, a solid understanding of double materiality assessment methodology, and a demonstrable track record of leading CSRD reporting projects for companies of comparable size and sector. Familiarity with the 2026 regulatory updates, including the revised ESRS adopted in July 2026 and the Omnibus I scope changes, is increasingly important when evaluating candidates.

Beyond regulatory knowledge, look for these practical qualities:

• Cross-functional communication skills: CSRD reporting draws on data from finance, HR, procurement, and operations. A specialist who cannot translate regulatory requirements into clear, accessible language for non-sustainability colleagues will struggle to obtain the information they need.
• Experience with data collection and verification: The revised ESRS reduced mandatory data points by over 60%, but the data that remains must be accurate and auditable. Practical experience structuring and validating data collection processes is essential.
• Sector-relevant experience: CSRD requirements play out differently depending on your industry. A specialist with experience in your sector will reach productive output more quickly and identify the disclosure issues most relevant to your specific context.
• Familiarity with assurance requirements: Sustainability statements require limited assurance from an approved auditor. A strong CSRD specialist understands what assurance providers assess and helps prepare your documentation to meet those expectations.

The right candidate combines regulatory depth with practical project management capability. Technical knowledge alone is insufficient if the specialist cannot navigate your organization and keep a reporting project on track. When evaluating candidates, ask for specific examples of CSRD or ESRS projects they have led, rather than relying on general sustainability experience as a proxy. Knowing what to look for is one part of the equation — knowing when to bring someone in is equally important.

When is the right time to bring in an interim CSRD specialist?

The right time is before you are under pressure, not after. That said, there are several specific moments when bringing in temporary CSRD support is particularly well-suited to your situation. The most obvious is when your reporting deadline is approaching and your internal team lacks the capacity or expertise to deliver a compliant sustainability statement independently.

There are other trigger points worth considering:

• When you are starting your first CSRD report: The first reporting cycle is generally the most demanding. Engaging an expert early to establish your double materiality assessment, data architecture, and internal process reduces the risk of significant rework later.
• When your sustainability team is short-staffed: A maternity leave, an unexpected departure, or a team that was never structured to manage this level of regulatory complexity are all valid reasons to bring in interim support.
• When the regulatory landscape shifts: The 2026 Omnibus changes and the revised ESRS introduced meaningful adjustments to scope and data requirements. If your team has not fully assessed what changed and what it means for your reporting obligations, that is a clear signal that external expertise is warranted.
• When you are preparing for assurance: If your sustainability statement is approaching its first limited assurance review, a specialist who understands what auditors evaluate can make the difference between a straightforward process and a disruptive one.

The common thread across all of these situations is a gap between what your team can handle and what the regulation requires. An interim CSRD expert addresses that gap without requiring you to build a permanent function around a need that may be cyclical or time-limited. Once you have identified the right moment to act, the next practical question is how quickly that support can actually be in place.

How quickly can a CSRD freelancer be onboarded and productive?

A pre-screened CSRD freelancer can typically be matched, onboarded, and contributing within days rather than weeks. Unlike a permanent hire or a large consultancy engagement, a freelance interim specialist does not require lengthy procurement processes or extended notice periods. When your situation is time-sensitive, that speed is genuinely valuable.

The onboarding process itself depends on how prepared your organization is. A specialist will need access to your existing sustainability data, a clear understanding of your reporting boundaries, and introductions to the key internal stakeholders they will be working with. If you have already completed groundwork on your double materiality assessment or produced previous sustainability reports, they can build on that foundation quickly.

One factor that significantly improves onboarding efficiency is clarity on scope before the engagement begins. Establishing whether you need someone to lead the full CSRD reporting process, provide support on a specific ESRS topic, or prepare your data for assurance allows the expert to begin contributing immediately rather than spending their initial time clarifying what is actually required. That question of scope also connects directly to the broader decision of how to structure the engagement itself.

Should a CSRD expert work on a project or interim basis?

The appropriate arrangement depends on the nature and duration of your CSRD-related needs. A project-based engagement is well-suited to situations where you have a defined deliverable with a clear end point, such as completing your first double materiality assessment or drafting a specific section of your sustainability statement. An interim arrangement is more appropriate when you need someone to function as a de facto team member over a longer period, covering an ongoing role or managing a full reporting cycle.

For most companies approaching their first or second CSRD report, an interim arrangement tends to deliver greater value. Reporting is rarely a clean, linear process — it involves iteration, internal alignment, and responding to queries from auditors or senior leadership. Having a specialist embedded over several months means they can adapt as your needs evolve, rather than delivering a fixed output and stepping back at a critical moment.

That said, project-based engagements are a well-suited choice for highly specific, bounded tasks. If your team is largely capable but requires expert input on one particular ESRS topic, or if you need a specialist to review and validate work your team has already produced, a project scope keeps the engagement focused and cost-effective. Both models are available, and many organizations begin with a project engagement and extend it into an interim arrangement once they have seen the value in practice — which brings us to how to take that first step.
