Norway's $2 Trillion Oil Fund Calls on EU to Allow Single Report for ESRS and ISSB Compliance

Norges Bank Investment Management, the investment manager for Norway's $2 trillion Government Pension Fund Global, has submitted a response to the European Commission's consultation on the revised European Sustainability Reporting Standards, calling on the Commission to introduce targeted reforms that would allow companies to satisfy both ESRS and ISSB requirements through a single report. NBIM, which manages approximately EUR 1.79 trillion in assets including EUR 232 billion invested across more than 1,000 companies in EU member states, argued that closer alignment between European and global standards would enable investors to compare sustainability information across jurisdictions more easily while reducing the dual reporting burden on companies. Carine Smith Ihenacho, Chief Governance and Compliance Officer at NBIM, said that true simplification means one report rather than two, and that a few targeted reforms can deliver this outcome with benefits for companies, investors and European capital markets alike.

 

The Context of the ESRS Revision

 

The Commission's consultation follows the release of a new draft ESRS under its Omnibus I simplification initiative, which has already dramatically reduced the number of companies covered by mandatory CSRD requirements by 90 percent, removing companies with less than €450 million in revenue and 1,000 employees compared to the previous 250 employee threshold. EFRAG's technical advice underpinning the revision included a 61 percent reduction in mandatory datapoints and the elimination of all voluntary disclosures, resulting in a total datapoint reduction of over 70 percent. While supporting the simplification direction, NBIM's response urges the Commission to go further in aligning the revised ESRS with ISSB standards, which have been adopted in 42 jurisdictions representing approximately 60 percent of global GDP.

Prior to the Commission's release of the draft ESRS, media reports had indicated consideration of much closer ISSB alignment, leading to warnings that this could diminish the European standard's distinctive double materiality approach, which requires reporting on both the risks that sustainability issues pose to enterprises and the impacts that enterprises have on environment and society. NBIM addressed this tension directly, arguing that the ISSB model's building blocks approach allows jurisdictions to adopt the global baseline while adding requirements suited to broader sustainability ambitions, meaning the EU can maintain its double materiality objectives while preserving the comparability of financially material information across frameworks.

NBIM's Key Recommendations

 

The two central technical amendments NBIM recommends are a non-obscuring principle and a flexible presentation format. The non-obscuring principle would require investor-relevant information within a sustainability statement to be clearly identifiable and not obscured by disclosures directed at other audiences, mirroring a provision already contained in IFRS S1 but absent from the current ESRS. The flexible presentation format would give companies the option to present disclosures in a way that facilitates compliance with both ESRS and ISSB requirements, removing the structural barrier created by the ESRS mandatory four-part disclosure structure that differs from the flexible presentation approach permitted under IFRS S1.

Beyond these structural amendments, NBIM also recommends avoiding new changes in the revised ESRS that reduce interoperability with ISSB standards, including the extension of the commercial prejudice exemption to anticipated financial effects disclosures and the phase-in of quantitative non-climate anticipated financial effects disclosures until 2030. The fund also calls for referencing IFRS industry-based guidance incorporating SASB standards in the ESRS double materiality assessment to strengthen industry-specific financial materiality alignment, and for the Commission to work with the ISSB as it develops its nature-related disclosure practice statement to support convergence between European and global approaches.

The Investor Case for ISSB Alignment

 

NBIM's position reflects the perspective of a globally diversified institutional investor that holds companies across dozens of jurisdictions and must compare sustainability information across frameworks that differ in structure, datapoints and materiality definitions. Smith Ihenacho said the draft ESRS represents a step forward but emphasised that single-report compliance with both ESRS and ISSB standards is the standard that would genuinely serve investor needs. The argument that European companies facing both ESRS obligations and ISSB-aligned requirements from their international investors and capital market counterparties should not bear the cost of producing two separate reports resonates with the Commission's own stated simplification agenda.

The ISSB's emergence as the global baseline for investor-focused sustainability reporting, with adoption across 42 jurisdictions representing 60 percent of global GDP, creates a structural reality that the EU must engage with if European companies are to remain competitive in international capital markets. Companies operating across ESRS and ISSB jurisdictions simultaneously face compliance complexity that increases cost, reduces comparability and potentially disadvantages European companies relative to international peers operating under a single framework. NBIM's recommendations aim to resolve this without requiring the EU to abandon its double materiality approach.

 

Outlook for ESRS Finalisation and Global Sustainability Reporting Convergence

 

The Commission's consultation period will gather input from a range of stakeholders before finalising the revised ESRS, with NBIM's submission representing one of the most influential investor perspectives given the fund's scale and its substantial European equity holdings. The degree to which the Commission incorporates ISSB alignment amendments into the final standards will determine whether European companies can achieve single-report compliance or must maintain parallel reporting processes for different jurisdictions and investor audiences. Sustained progress toward convergence would reduce reporting costs, improve comparability for global investors and strengthen European capital market competitiveness at a moment when the regulatory simplification agenda is a stated priority.

Whether the final revised ESRS successfully balances the EU's double materiality ambitions with the global investor demand for ISSB-compatible financially material information will be one of the defining decisions in the evolution of global sustainability reporting standards. The outcome will influence not only European company reporting but the trajectory of international standard convergence as the ISSB, GRI and regional regulators continue to develop their respective frameworks. NBIM's intervention demonstrates how major institutional investors are increasingly using their regulatory engagement to shape the standards that govern the information they need to make long-term capital allocation decisions.
