EU moves towards simplifying sustainability reporting amid legislative and market reforms

EU negotiations over the Omnibus I package have opened a clear pathway to further simplify the Corporate Sustainability Reporting Directive (CSRD), inserting language that explicitly ties any extension of the law’s scope to the possibility of a “simplified reporting regime”.

According to the original text of the CSRD, the Commission shall report by end-April 2029 on whether reporting rules “should be further extended”. The revised Omnibus text, approved by EU member state representatives and due for a vote in the European Parliament next week, adds: “When considering the possible extension of the scope, it is important that the Commission consider whether to balance this extension with a possibility to establish a simplified reporting regime.” The text also requires the review to weigh “the needs for sustainability data to mobilise private investments towards EU Green Deal objectives on the one hand, and the influence of sustainability reporting on the competitiveness of the EU undertakings on the other hand”, signalling a stronger tilt towards regulatory proportionality and competitiveness concerns.

The insertion formalises a policy direction that has been developing across EU institutions. The Council adopted a negotiating mandate this year to simplify sustainability reporting and due diligence requirements to boost EU competitiveness, a push presented by member states as necessary to reduce reporting burdens and limit knock-on obligations for smaller firms. Reuters reporting of a political deal last week further indicated tougher carve-outs: negotiating adjustments would raise thresholds such that CSRD obligations would apply only to companies with over 1,000 employees and more than €450 million in turnover, potentially excluding a significant swathe of currently in-scope firms. The Reuters report also said non-compliance penalties under the revised approach would be capped at 3% of global turnover and that the new rules are expected to come into force by July 2029.

Industry and investor standard-setters are moving in parallel to refine the detail of sustainability disclosures. The International Sustainability Standards Board (ISSB) has issued targeted amendments to its S2 climate standard, addressing application challenges firms encountered when implementing GHG disclosure requirements. The ISSB’s changes , which permit, for example, certain exclusions for Scope 3 Category 15 emissions and provide practical clarifications , take effect for reporting periods beginning on or after 1 January 2027, with early application allowed. The ISSB said the targeted amendments respond to specific implementation issues raised by market participants following its earlier exposure draft consultation.

Regulatory pragmatism is evident elsewhere. The European Banking Authority recommended suspending banks’ disclosure of the Green Asset Ratio (GAR) until the end of 2026 amid criticism of methodological asymmetries; the European Central Bank said it “intends to follow the EBA’s recommendation and does not intend to prioritise the enforcement of the above-mentioned disclosures”. That move, and the Omnibus’ new wording on simplified regimes, underscores a broader EU tendency to sequence and, in some cases, modulate the pace and scope of disclosure obligations.

At the same time, actors across financial services continue to develop tools and expectations to channel capital towards climate and resilience outcomes. UNEP Finance Initiative has launched a framework, co-developed with consultancy Cadlas, to measure the impact of financial institutions’ investments in adaptation and resilience. The resource aims to help institutions establish metrics that are “contextually relevant”, addressing persistent gaps such as mismatched time horizons between financial reporting cycles and adaptation benefits, and data shortages. The framework builds on extant approaches including the Climate Bonds Resilience Taxonomy and the IIGCC’s Physical Climate Risk Appraisal Methodology 2.0.

Investor groups and market participants are also sharpening expectations on climate risk integration. The Institutional Investors Group on Climate Change updated investor expectations for how climate-related risks and uncertainties should be reflected in financial statements, calling for firms, auditors and audit committees to disclose critical assumptions quantitatively and to provide sensitivity analyses. ShareAction’s latest banking survey found that while three-quarters of debated decarbonisation targets are benchmarked to 1.5C scenarios and every bank surveyed had at least one 1.5C-aligned target, only nine of 25 banks align all their targets to a 1.5C pathway , highlighting gaps between ambition and comprehensive planning.

Corporate and market responses continue to accumulate: Munich Re has set a new insured-emissions decarbonisation target using the PCAF methodology and pledged not to expand insurance exposure to oil and gas production, while increasing “climate tackling” investments. S&P Global Ratings was approved as an external reviewer for the Climate Bonds Initiative’s climate bonds standard, a development the CBI described as “a major milestone for the rapid scaling of credible climate finance.” Meanwhile, at the national level, a coalition of Japanese life insurers reported progress in their stewardship activities and plans for further corporate engagement on climate disclosure.

Taken together, the Omnibus revisions and parallel developments at standard-setters, supervisors and market actors paint a picture of an EU sustainability architecture in transition: policymakers are incorporating flexibility and simplification into the machinery of expansion, while standard-setters and investors press for usable, comparable data and robust methodologies. According to the announcement of the Omnibus agreement, the Commission’s forthcoming 2029 review will thus be required to balance the mobilisation of private investment for EU Green Deal objectives against the reported competitive impacts of sustainability reporting , a test that will determine whether future extensions of CSRD widen disclosures or instead create tiered, streamlined regimes for different categories of companies.
