EU Sustainability Reporting Value Chain Cap: What Businesses Should Prepare After Omnibus I

European sustainability reporting is entering a more focused phase. The reporting landscape still requires companies to understand their material environmental, social, and governance impacts, risks, and opportunities. The operating model for collecting value-chain information is becoming more proportionate.

The EU sustainability reporting value chain cap is one of the most important changes introduced through the Omnibus I simplification package. It limits the sustainability information that companies subject to the Corporate Sustainability Reporting Directive can require from value-chain partners with 1,000 employees or fewer.

 

This change matters for large reporting companies, smaller suppliers, non-EU exporters, procurement teams, sustainability professionals, and businesses that receive increasingly detailed ESG questionnaires from customers, banks, and commercial partners.

 

The new rules reduce excessive information requests. They do not remove the need for credible sustainability data. Companies should now focus on collecting information that is relevant, proportionate, decision-useful, and connected with material business risks.

 

Key Takeaways

  • The Omnibus I simplification package narrows mandatory CSRD scope to companies with more than 1,000 employees and more than €450 million in net annual turnover.
  • The European Commission’s draft revised ESRS reduce mandatory datapoints by more than 60% and total datapoints by more than 70%.
  • The CSRD value chain cap protects value-chain partners with 1,000 employees or fewer from being required to provide sustainability information beyond the limits of the voluntary standard.
  • Companies subject to CSRD may still request additional information, but suppliers must be told when the request exceeds the statutory cap and that they have the right to decline.
  • Smaller companies should still develop a practical ESG data pack because customers, banks, investors, and regulatory frameworks may continue to request sustainability information for legitimate business purposes.

 

What Changed Under Omnibus I?

The European Union introduced the Omnibus I simplification package to reduce complexity, administrative burden, and the indirect reporting pressure placed on smaller businesses.

 

On 24 February 2026, the Council of the European Union gave its final approval to legislation simplifying the Corporate Sustainability Reporting Directive and the Corporate Sustainability Due Diligence Directive.

 

The updated CSRD scope is narrower than the original framework.

Area

Updated Position

EU companies within mandatory CSRD scope

Companies with more than 1,000 employees and more than €450 million in net annual turnover

Third-country parent undertakings

Companies with more than €450 million in EU net turnover

Relevant EU subsidiary or branch threshold for third-country undertakings

More than €200 million in generated turnover

Wave-one transition relief

Certain companies that reported for financial year 2024 but fall outside the revised scope receive an exemption for 2025 and 2026

Smaller value-chain partners

Protected through the new value chain cap where they have 1,000 employees or fewer

The Council of the European Union explained that the package aims to reduce unnecessary barriers, improve efficiency, and limit the trickle-down effect on smaller companies.

 

This is a significant recalibration of the EU sustainability-reporting framework. Companies should assess how the revised thresholds affect their reporting obligations, customer requests, supplier-data systems, and ESG readiness plans.

 

What Is the EU Sustainability Reporting Value Chain Cap?

Companies subject to the CSRD must report material sustainability risks, impacts, and opportunities, including relevant issues arising across their value chains.

 

This can require information from suppliers, service providers, contractors, and other business partners. Before the Omnibus I changes, smaller companies frequently received extensive ESG questionnaires because larger businesses needed information for reporting, risk management, financing, or customer requirements.

The European Commission describes this indirect pressure as the trickle-down effect.

 

The EU sustainability reporting value chain cap limits this pressure. A company subject to the CSRD cannot require a value-chain partner with 1,000 employees or fewer to provide more sustainability information than the voluntary reporting standard permits.

 

The European Commission’s May 2026 explanatory guidance makes the position clear:

  • The cap applies to companies with 1,000 employees or fewer.
  • It applies where information is requested for the purpose of CSRD sustainability reporting.
  • It does not prevent companies from requesting information beyond the cap.
  • A requesting company must clearly identify when the request exceeds the cap.
  • The smaller company must be informed that it has a statutory right to decline the additional request.
  • The voluntary standard does not create a mandatory reporting obligation for smaller suppliers.

This distinction is essential. The value chain cap creates proportionality. It does not remove sustainability information from commercial decision-making.

 

Why the Value Chain Cap Was Introduced?

The original CSRD framework created practical challenges for smaller companies outside mandatory reporting scope.

 

A business with a limited sustainability team could receive multiple questionnaires from customers, lenders, investors, and commercial partners. Each request could use a different format, terminology, reporting boundary, and level of detail.

 

The burden increased where businesses had to respond to:

  • Greenhouse gas emissions questionnaires
  • Workforce and health-and-safety requests
  • Supplier-code confirmations
  • Water and waste data requests
  • Due-diligence forms
  • Human-rights questionnaires
  • Climate-risk surveys
  • Procurement scorecards
  • Bank sustainability assessments
  • Tender-related ESG submissions

The issue was especially relevant for smaller suppliers serving several large companies.

 

The revised framework introduces a standardised boundary for CSRD-related requests. This should help reduce duplication and encourage a more consistent approach.

 

The European Commission stated that the draft voluntary standard is intended to support companies outside mandatory CSRD scope while protecting smaller value-chain partners from excessive requests.

 

What Is the Voluntary Sustainability Reporting Standard?

The value chain cap depends on a voluntary reporting standard for companies outside mandatory CSRD scope.

 

The European Commission published its original VSME recommendation in July 2025. The VSME was developed by EFRAG as a simplified reporting tool for small and medium-sized undertakings.

 

In May 2026, the Commission published a draft voluntary standard that builds on the VSME approach. The draft is designed to support smaller businesses and define the maximum information that CSRD-reporting companies can require from protected value-chain partners.

 

The draft standard contains two modules:

Module

Purpose

Basic Module

Designed as an accessible starting point, including for micro-undertakings

Comprehensive Module

Builds on the Basic Module and provides additional information for companies with greater reporting needs

The draft also categorises disclosures as:

Disclosure Category

Meaning

Necessary

Information a company applying the standard is expected to report

Necessary if applicable

Information required when relevant conditions apply

Voluntary

Information a company may provide at its discretion

Consideration when reporting sector information

Additional information that may be important for a specific sector

The European Commission’s explanatory guidance states that only disclosures marked as necessary fall within the value chain cap.

 

This means that CSRD companies cannot require smaller suppliers to provide every possible disclosure contained in the voluntary standard. They should request information that is genuinely needed for their reporting obligations.

 

How the Revised ESRS Change Reporting Expectations

The European Commission also published draft revised European Sustainability Reporting Standards in May 2026. The revised ESRS aim to improve usability and reduce excessive complexity.

 

According to the European Commission, the draft revised standards:

  • Reduce mandatory datapoints by more than 60%
  • Reduce total datapoints by more than 70%
  • Introduce additional flexibility
  • Simplify materiality assessments
  • Improve clarity
  • Reduce expected reporting costs per company by more than 30%

 

These changes are important for companies that remain within mandatory CSRD scope. They also matter for value-chain partners because simplified reporting requirements should influence the type and volume of supplier information requests.

 

The revised framework still requires disciplined reporting. A smaller number of datapoints does not reduce the importance of data quality, governance, traceability, and materiality.

 

What Does Materiality Mean Under the Revised Framework?

Materiality remains central to sustainability reporting.

Companies should identify which environmental, social, and governance matters are relevant to their impacts, risks, opportunities, strategy, and financial performance. This means supplier information should be requested where it supports a clear reporting need.

 

A procurement team should be able to explain:

  • Why the data is required
  • Which reporting obligation it supports
  • Whether the request falls within the value chain cap
  • Whether the information is material
  • How the data will be used
  • Whether a simpler data request would be sufficient
  • Whether the supplier has the right to decline additional information

The purpose of simplification is to create a more targeted system. Large companies should avoid sending standardised questionnaires that collect information without a clear reporting purpose.

 

What Larger CSRD Companies Should Do?

Companies that remain within mandatory CSRD scope need to revise their supplier-data strategies.

The new framework requires proportionality, transparency, and better coordination between sustainability, finance, legal, procurement, risk, and supply-chain teams.

 

Step 1: Review Supplier Questionnaires

Existing ESG questionnaires should be assessed against the new value chain cap.

Questions should be divided into three categories:

Category

Action

Within the value chain cap

Retain where relevant and necessary

Beyond the value chain cap but commercially useful

Clearly label as additional and inform suppliers of their right to decline where required

Not clearly linked with reporting or risk management

Remove or reconsider

This exercise can reduce unnecessary supplier burden and improve data quality.

 

Step 2: Identify Protected Suppliers

Companies should determine which suppliers and value-chain partners have 1,000 employees or fewer. The supplier master data should record:

  • Company size
  • Sector
  • Geographic location
  • Strategic importance
  • ESG risk profile
  • Existing reporting maturity
  • Whether the supplier falls within the protected category
  • Whether additional information requests have been made

This creates a more defensible and auditable information-request process.

 

Step 3: Define Material Data Needs

Sustainability teams should identify the minimum information needed for CSRD reporting.

Examples may include:

  • Scope 3 emissions data
  • Energy consumption
  • Water use
  • Waste information
  • Workforce indicators
  • Health-and-safety metrics
  • Human-rights due-diligence information
  • Supplier policies
  • Environmental certifications
  • Sector-specific risk information

The appropriate level of detail depends on the company’s material topics and reporting boundary.

 

Step 4: Update Procurement Policies

Procurement documents should explain how sustainability information will be requested and used.

Supplier onboarding forms, tender requirements, contractual clauses, codes of conduct, and periodic review processes should align with the revised framework.

 

Step 5: Train Commercial Teams

Procurement managers, supplier-relationship teams, legal teams, and sustainability professionals should understand the cap.

Training should cover:

  • Which suppliers are protected
  • What information falls within the voluntary standard
  • When requests exceed the statutory cap
  • How additional requests should be labelled
  • How suppliers should be informed of their right to decline
  • How materiality should guide information collection

 

Step 6: Maintain an Evidence Trail

Companies should document the purpose of sustainability data requests. A clear audit trail can explain:

  • Which reporting requirement the data supports
  • Why the information is necessary
  • Whether the request exceeds the cap
  • Whether the supplier was informed
  • Whether the supplier responded voluntarily
  • How the information was used

This improves governance and reduces the risk of excessive or inconsistent requests.

 

What Smaller Suppliers Should Do?

The value chain cap provides protection, but smaller businesses should still prepare a practical sustainability data pack. A company may receive ESG requests from:

  • Customers
  • Banks
  • Investors
  • Government entities
  • Tender authorities
  • Multinational groups
  • Export partners
  • Industry platforms
  • Certification bodies
  • Supply-chain rating providers

 

Some requests may be linked with CSRD reporting. Others may relate to financing, procurement, due diligence, contractual requirements, risk management, or market access.

 

A smaller supplier should build a proportionate reporting system that can answer recurring questions efficiently.

 

Step 1: Establish a Basic ESG Data File

A practical data file can include:

Area

Example Information

Company profile

Employees, sites, activities, and major markets

Energy

Electricity and fuel consumption

Emissions

Available Scope 1 and Scope 2 emissions data

Water

Water consumption and relevant exposure

Waste

Waste volumes, disposal routes, and recycling data

Workforce

Employees, health-and-safety indicators, training, and diversity information

Policies

Environmental, health-and-safety, labour, ethics, and supplier policies

Certifications

ISO certifications, environmental accreditations, and sector-specific evidence

Governance

Management responsibility for sustainability and compliance

Targets

Practical improvement goals and planned actions

This can reduce response time when customers request sustainability information.

 

Step 2: Distinguish Mandatory and Additional Requests

Suppliers should review incoming questionnaires carefully.

For each request, the business should ask:

  • Is this request connected with CSRD reporting?
  • Does the request fall within the voluntary standard?
  • Has the requesting company identified any additional information beyond the cap?
  • Has the company explained that the supplier may decline additional CSRD-related requests?
  • Is the information still commercially useful to provide voluntarily?
  • Does the request relate to another regulatory, financing, contractual, or procurement requirement?

A structured review process helps management make informed decisions.

 

Step 3: Use the Voluntary Standard as a Practical Starting Point

The voluntary reporting standard can help suppliers organise their sustainability information.

 

The standard provides a common language that can reduce duplication. It can also improve responses to banks, customers, investors, and procurement teams.

 

Step 4: Avoid Unsupported Claims

Smaller businesses should provide accurate information and disclose limitations.

A company should avoid presenting broad sustainability claims without evidence. Data should be supported by records, invoices, internal systems, calculations, or recognised methodologies.

 

Why GCC and UAE Businesses Should Pay Attention?

The revised EU framework is relevant beyond Europe.

 

Many UAE and GCC businesses export goods, provide services, operate within global supply chains, supply multinational groups, or engage with banks and investors that use EU-aligned sustainability frameworks.

 

A UAE-based company may fall outside direct CSRD scope while still receiving ESG information requests from European customers.

This can affect sectors such as:

  • Manufacturing
  • Construction materials
  • Logistics
  • Food and agriculture
  • Textiles
  • Chemicals
  • Energy services
  • Technology
  • Professional services
  • Real estate
  • Hospitality
  • Financial services

 

The value chain cap gives smaller businesses greater protection from excessive CSRD-related requests. It also encourages companies to organise their ESG information in a more structured format.

 

For GCC businesses, this creates a practical opportunity. A supplier with a clear sustainability data pack can respond efficiently, improve customer confidence, and strengthen its position in international procurement processes.

Frequently Asked Questions (FAQs)

What is the EU sustainability reporting value chain cap?

The value chain cap limits the sustainability information that companies subject to CSRD reporting can require from value-chain partners with 1,000 employees or fewer. The maximum required information is defined through the voluntary reporting standard.

Does the value chain cap apply to every sustainability questionnaire?

No. The cap applies in the context of information requests for CSRD sustainability reporting. Requests connected with other regulatory, contractual, financing, due-diligence, or procurement purposes may still apply.

Can a smaller supplier refuse to provide additional information?

Where a CSRD-reporting company requests information beyond the value chain cap for CSRD reporting purposes, the supplier has a statutory right to decline the additional request.

Is the VSME reporting standard mandatory?

No. The VSME recommendation and the future voluntary reporting standard are intended to support companies outside mandatory CSRD scope. Their use is voluntary.

How many datapoints are being removed from the ESRS?

The European Commission stated that the draft revised ESRS reduce mandatory datapoints by more than 60% and total datapoints by more than 70%.

Should non-EU companies prepare for the revised framework?

Yes. Companies outside the EU may still supply European groups, operate within international value chains, or receive ESG requests from customers, banks, and investors. A proportionate sustainability data system can improve readiness.

From Reporting Burden to Reporting Discipline

The revised EU framework changes the way companies should think about sustainability data collection.

Large reporting companies need more targeted supplier-information systems. Smaller businesses need proportionate ESG data packs. Procurement teams need clearer request protocols. Sustainability teams need stronger materiality filters.

The next phase of sustainability reporting will reward organisations that collect useful information, maintain credible evidence, and understand which requests are genuinely necessary.
