Private fund managers particularly small sized AIFMs and GPs, face significant practical obstacles in implementing SFDR effectively and communicating their ESG commitments in a compelling way. With the new SFDR 2.0 expected to enter into force in 2028 or 2029 latest and the introduction of legally binding product categories, minimum investment thresholds and mandatory exclusion rules, these challenges are expected to intensify.

1.     Lack of reliable ESG data

The greatest operational obstacle that AIFMs grapple with is the absence of reliable, standardised and auditable ESG data flowing from portfolio companies. SFDR periodic reporting relies heavily on sustainability indicators, Principal Adverse Impact (PAI) metrics and sustainable investment assessments.

However, the narrowing of the Corporate Sustainability Reporting Directive (CSRD) scope under the Omnibus package means that small and medium-sized companies to which private equity funds commit long-term capital will no longer be required to produce sustainability report and disclosed standardised ESG data.

As a result, AIFMs will have to continue to collect ESG data manually through questionnaires, direct engagement or third-party providers.

This creates several problems:

·       Data collection is resource-intensive and difficult to scale

·       Information is often incomplete, inconsistent or estimated

·       The rating methodologies of third party ESG data vendors often lack transparency

·       Data is difficult to verify and audit

For private market funds with illiquid assets and smaller investee companies, this creates a structural reporting gap that directly affects SFDR compliance.

2.     Regulatory complexity and constant interpretation

SFDR is structured around a multi-level regulatory architecture involving:

·       Level 1 regulation

·       Level 2 Regulatory Technical Standards (RTS)

·       ESAs guidance and Q&As

·       Supervisory expectations set by national authorities such the CSSF

As a result, fund managers must constantly interpret overlapping regulatory texts and supervisory expectations. Smaller AIFMs without dedicated ESG legal teams face two difficult options:

·       accept legal uncertainty and compliance risk, or

·       rely extensively on costly external legal counsel.

This complexity increases operational burden and costs and creates regulatory uncertainty around how disclosures will be interpreted by regulators.

3.     Risk of mismatch between disclosures and reality

SFDR disclosures are not merely marketing statements; they are considered binding commitments to investors.

Fund managers must continuously demonstrate that:

·       Environmental and social characteristics and sustainable investments objective characteristics and

·       exclusion policies are applied

·       sustainable investment thresholds are maintained

·       PAIs are monitored

·       methodologies are documented and defensible

The CSSF has clarified that failing to respect the binding commitments as established in periodic disclosures may constitute a contractual breach with investors.

Under SFDR 2.0, this risk becomes even greater because the framework introduces:

·       mandatory 70% investment thresholds

·       mandatory exclusion lists as per the Paris Aligned Benchmark (PAB) and the Climate Transition Benchmark (CTB)

·       stricter sustainability indicators

·       ongoing depositary monitoring

A single non-compliant investment could jeopardise an entire fund’s product classification and potentially “downgrade” the fund classification.

4.     Insufficient internal resources

Many private market managers operate with lean teams and limited ESG expertise. Unlike large asset managers, smaller AIFMs often lack:

·       dedicated sustainability specialists

·       internal legal support

·       ESG reporting and data infrastructure

·       automated monitoring systems.

This leads to a reactive compliance approach where firms struggle to keep pace with regulatory developments, supervisory expectations and disclosure updates.

The operational burden is substantial because SFDR compliance requires:

·       ongoing portfolio monitoring

·       ESG data collection

·       documentation updates

·       internal governance controls

·       staff training

·       investor reporting

The cost of maintaining compliance diverts resources away from core investment decision and portfolio management activities.

5.     Commercial and fundraising pressures

SFDR compliance has become a factor of competitive differentiation rather than solely a regulatory requirement. Institutional investors increasingly assess ESG credibility during manager selection and due diligence processes.

Weak or inconsistent SFDR disclosures can affect:

·       investor confidence

·       fundraising capacity

·       access to institutional mandates

·       reputational standing

Recent withdrawals of mandates by large pension funds from global asset managers over ESG concerns demonstrate that sustainability commitments are now a baseline expectation in the market.

6.     Preparing for SFDR 2.0

Although SFDR 2.0 is unlikely to apply before 2028 or 2029, the operational changes required are significant. Fund managers must begin preparing now by:

·       strengthening ESG data collection processes

·       implementing monitoring and governance controls

·       reassessing fund classification strategies

·       designing measurable sustainability KPIs

·       building internal compliance capabilities

The transition from a disclosure regime to a product categorisation framework will require a fundamental restructuring of ESG governance and reporting systems across the private market industry.
