EU Opens Consultation on Further Changes to Corporate Sustainability Reporting Standards

The European Commission has opened a public consultation on revised European Sustainability Reporting Standards, marking the latest step in the EU’s effort to simplify corporate sustainability reporting under the Corporate Sustainability Reporting Directive.

The consultation, launched on 6 May 2026, covers draft revised ESRS for companies that remain in scope of mandatory reporting, as well as a voluntary sustainability reporting standard for smaller companies. Stakeholders have until 3 June 2026 to submit feedback before the Commission moves toward adoption through delegated acts.

The proposal comes as the EU continues to adjust its sustainability reporting framework through its wider simplification agenda. The aim is to reduce administrative costs and regulatory complexity for companies, while retaining sustainability information considered important for investors, lenders, regulators, customers and other business partners.

According to the Commission, the revised standards are shorter and clearer, introduce more flexibility for reporting companies and simplify the materiality assessment used to determine which sustainability topics must be disclosed.

Datapoint Reductions at the Centre of the Proposal

The scale of the proposed reduction is significant. The Commission says the draft revised ESRS would cut mandatory datapoints by more than 60% and total datapoints by more than 70%. It also estimates that the changes could reduce reporting costs per company by more than 30%.

These reductions matter because many companies preparing for CSRD compliance have had to build new systems for collecting, validating and reporting sustainability data. The first version of the ESRS required companies to assess and disclose information across a wide range of environmental, social and governance topics, including climate change, pollution, water, biodiversity, circular economy, workforce issues, affected communities, consumers and business conduct.

For large companies, this has involved coordination between sustainability teams, finance departments, legal teams, procurement teams, risk functions, auditors and external software providers. For smaller companies in large value chains, the rules have also increased pressure to provide data to customers and financial institutions, even where they are not directly subject to mandatory reporting.

The Commission’s proposal is therefore intended to make the reporting framework more manageable, especially for companies that argued the original requirements were too complex, costly or difficult to implement within the required timelines.

What the ESRS do under the CSRD

The ESRS are the technical rules that define what companies must report under the CSRD. They translate the directive’s broad sustainability reporting obligations into specific disclosure requirements and datapoints.

The standards are built around the concept of double materiality. This means companies must consider both how sustainability issues affect their financial position and how their own activities affect people and the environment. In practical terms, a company may need to report on climate risks to its business, but also on the emissions, pollution, resource use or social impacts linked to its operations and value chain.

This approach is more comprehensive than traditional financial reporting and has made the CSRD one of the most ambitious corporate sustainability disclosure regimes globally. However, it has also created implementation challenges, particularly for companies with complex international supply chains or limited internal reporting capacity.

The proposed revisions do not remove the underlying sustainability reporting framework. Instead, they aim to make it more focused by reducing the number of required datapoints, clarifying expectations and giving companies more room to apply judgement when deciding what information is material.

Voluntary Standard for Smaller Companies

A central part of the package is a voluntary sustainability reporting standard for companies with up to 1,000 employees. This standard is intended to help smaller companies provide sustainability information in a proportionate way when requested by banks, investors, customers or larger companies in their value chain.

The voluntary standard is also linked to the proposed “value chain cap”. This measure is designed to limit the amount of sustainability information that larger CSRD-covered companies can request from smaller business partners. In practice, it should prevent large companies from passing the full burden of CSRD-style reporting down to smaller suppliers.

This could be particularly important for small and medium-sized enterprises that are not directly subject to mandatory CSRD reporting but still face growing demand for emissions, energy, labour, governance and supply-chain data. Without a common voluntary standard, smaller suppliers may receive multiple questionnaires from different customers, each using different formats, definitions and metrics.

A recognized voluntary standard could make those requests more predictable and reduce duplication. It could also help smaller firms start building basic sustainability data systems without having to comply with the full mandatory ESRS framework.

Implications for Companies and Reporting Teams

For companies already preparing CSRD reports, the proposal may change the level of detail required across environmental, social and governance topics. Climate-related reporting remains a central part of the ESRS framework, but companies may have fewer individual datapoints to collect, validate and disclose.

This could affect reporting software configurations, internal controls, assurance planning and data collection from subsidiaries and suppliers. Companies that have already invested heavily in CSRD readiness may need to review whether their current reporting templates still align with the revised standards once they are finalised.

At the same time, businesses should avoid assuming that sustainability reporting obligations are disappearing. The direction is toward simplification, not removal. Companies that remain within scope will still need governance processes, materiality assessments, climate-related information and auditable sustainability data.

The practical priority for reporting teams is to stay flexible. Companies should continue building reliable sustainability data systems, but avoid over-engineering datapoints that may no longer be mandatory under the revised framework.

Investor and Lender Concerns

For investors and lenders, the key question is whether simplification will preserve enough comparable and decision-useful information. Sustainability disclosures are increasingly used to assess climate transition risk, exposure to carbon pricing, energy efficiency, supply-chain resilience, biodiversity impacts and governance quality.

A shorter set of reporting requirements may make disclosures easier to produce and read. It may also help users focus on information that is genuinely material rather than navigating long reports filled with low-value datapoints.

However, there is a risk that too much flexibility could reduce comparability between companies, sectors and jurisdictions. If companies interpret materiality differently or omit information that investors consider relevant, sustainability reports may become harder to compare. This is particularly important for financial institutions using corporate data to assess transition finance, portfolio emissions and climate-related risk.

The challenge for regulators is therefore to reduce unnecessary complexity without weakening the quality, consistency and credibility of reported sustainability information.

Why it Matters for the Net-Zero Transition

The revised ESRS are directly relevant to the net-zero transition because sustainability reporting is not only a compliance exercise. Reliable corporate data supports emissions reduction planning, transition finance, capital allocation and procurement decisions.

Companies need credible information on Scope 1, Scope 2 and relevant Scope 3 emissions, as well as climate risks, energy use, decarbonization targets and progress against transition plans. Investors and lenders need comparable data to understand whether companies are managing climate risks and aligning capital expenditure with long-term transition goals.

If the standards become simpler without losing essential climate and environmental information, they could help companies focus on the data most relevant to real-world decision-making. But if the revisions reduce transparency too far, they could make it harder to evaluate corporate climate claims and track progress toward emissions reduction targets.

For sustainability software providers, consultants and assurance firms, the changes may also reshape demand. Companies are likely to continue needing tools and advisory support, but the focus may shift from managing large numbers of datapoints toward improving data quality, auditability and materiality judgement.

A Politically Sensitive Adjustment

The proposal reflects a wider political debate in Europe over the balance between competitiveness and sustainability regulation. Supporters of simplification argue that companies need clearer and less costly rules, especially as European businesses face pressure from energy costs, global competition and a complex regulatory environment.

Critics argue that reducing sustainability reporting obligations could weaken transparency, make greenwashing harder to detect and disadvantage companies that have already invested in high-quality sustainability reporting.

This tension is likely to continue as EU institutions review the final shape of the standards. Sustainability reporting has become a central part of Europe’s green finance architecture, but it is also increasingly being assessed through the lens of competitiveness and administrative burden.

What Happens Next

Stakeholders have until 3 June 2026 to respond to the Commission’s consultation. After that, the Commission is expected to review the feedback and move toward adopting the revised ESRS and voluntary standard through delegated acts.

Once adopted, the measures will be sent to the European Parliament and the Council for scrutiny. During that period, lawmakers may object, although the process does not involve rewriting the text in the same way as ordinary legislation.

For companies, the main message is to monitor the consultation and final delegated acts closely. Organisations in scope of the CSRD should continue preparing for sustainability reporting, but they should also review their systems once the revised standards are confirmed.

The EU’s sustainability reporting regime is being reshaped, not abandoned. The test will be whether the revised standards can reduce burden while preserving the transparency needed to support climate action, sustainable finance and Europe’s broader net-zero objectives.
