EU Sustainability Reporting for Non-EU Companies: What Global Businesses Need to Know

Sustainability reporting is no longer an issue limited to companies headquartered within the European Union. The EU's sustainability reporting framework can also affect non-EU companies with significant business activities in the European market, making it increasingly important for international groups to understand their reporting obligations, data requirements, and readiness.

The Corporate Sustainability Reporting Directive (CSRD) requires companies within its scope to report sustainability-related information using the European Sustainability Reporting Standards (ESRS). The framework covers environmental, social, and governance matters, including areas such as climate change, biodiversity, human rights, and sustainability-related risks and impacts. (Finance)

When Can a Non-EU Company Be in Scope?

A company does not necessarily need to be incorporated in Europe to have sustainability reporting obligations under EU rules.

Under the current framework, certain third-country undertakings can fall within the requirements where they generate significant turnover in the EU and have an EU presence through a subsidiary or branch. In particular, the rules address non-EU companies generating more than €150 million in EU net turnover and having either an EU subsidiary meeting the relevant conditions or an EU branch generating more than €40 million in net turnover.

Non-EU companies can also be affected where they have securities admitted to trading on an EU regulated market. (Finance)

Importantly, the EU sustainability reporting framework has been evolving. The European Commission adopted revised ESRS in July 2026 as part of the broader simplification of sustainability reporting requirements. These revised standards are intended to reduce reporting burdens and streamline disclosures, although the adopted amendments were not yet in force at the time of the Commission's announcement and remain subject to the applicable scrutiny process.

Why Does This Matter to Non-EU Businesses?

For international companies, EU sustainability reporting is more than a compliance exercise. It can influence how a company collects information across its global operations and supply chain.

A non-EU group may need to understand:

• Which entities within the group have an EU presence
• Whether the group's EU turnover meets the applicable thresholds
• Which sustainability matters are material to the business
• What information is required from subsidiaries and branches
• How sustainability data is collected and controlled
• Whether existing sustainability reporting can be aligned with ESRS requirements
• How external assurance requirements may affect reporting processes

This can be particularly challenging for multinational groups because sustainability information is often generated across different countries, subsidiaries, business units, and systems.

The Challenge of Data Collection

One of the biggest challenges is not necessarily writing the sustainability report—it is obtaining reliable and consistent data.

Environmental data may include greenhouse-gas emissions, energy consumption, water use, pollution, and resource use. Social information may involve employees, working conditions, human rights, and value-chain workers. Governance information can involve business conduct, risk management, and corporate governance.

For a global company, these data points may come from different systems and may be measured using different methodologies.

This makes strong internal controls over sustainability information increasingly important.

Companies should therefore begin treating sustainability information with the same level of discipline applied to important financial and operational information.

From Compliance to Business Value

Sustainability reporting can also provide strategic benefits.

A well-designed reporting process can help management identify:

Risks – such as climate exposure, supply-chain disruption, regulatory changes, and resource dependency.

Opportunities – including energy efficiency, new sustainable products, access to sustainable finance, and changing customer demand.

Operational improvements – through better measurement of energy, resources, emissions, workforce data, and supply-chain performance.

The European Commission describes sustainability reporting as a way for investors and other stakeholders to understand both the sustainability risks companies face and their impacts on people and the environment. (Finance)

The Role of the Value Chain

The implications of EU sustainability reporting can extend beyond companies that are directly subject to CSRD.

A smaller non-EU company may become part of the value chain of a company that is required to report. As a result, customers, financial institutions, or business partners may request sustainability information from suppliers.

The European Commission has recognized this issue and, in July 2026, adopted a voluntary sustainability reporting standard for smaller companies outside the CSRD scope. The framework is intended to make it easier for smaller companies to respond to sustainability-information requests while limiting excessive information demands from companies subject to CSRD. (Finance)

This means that even businesses outside the direct scope of EU sustainability reporting should pay attention to developments in the European market.

Preparing for the Future

Non-EU companies should not wait until a reporting deadline approaches before assessing their readiness.

A practical preparation process can include:

1. Determine your EU footprint
   Identify EU subsidiaries, branches, listings, and EU-generated turnover.
2. Assess your reporting obligations
   Determine whether the parent company or an EU entity falls within the applicable requirements.
3. Conduct a sustainability gap assessment
   Compare existing ESG reporting and data against the relevant EU requirements.
4. Establish data ownership
   Clearly identify who is responsible for collecting, reviewing, and approving sustainability information.
5. Strengthen internal controls
   Introduce appropriate controls over sustainability data, calculations, assumptions, and disclosures.
6. Engage the wider group
   Sustainability reporting should involve finance, audit, risk, legal, HR, operations, procurement, and senior management.
7. Prepare for assurance
   Companies should consider the quality and auditability of their sustainability information from the beginning of the reporting process.

Looking Ahead

The EU sustainability reporting landscape is changing rapidly. The European Commission's 2026 reforms are designed to simplify the ESRS and reduce administrative burdens while maintaining meaningful sustainability disclosures. The revised standards adopted in July 2026 reduce mandatory and overall data points substantially and introduce additional flexibility, but they will apply only once the required legislative process is completed. (Finance)

For non-EU companies, the key message is simple:

EU sustainability reporting is not only an EU issue.

If your organization has significant business activity in Europe, an EU subsidiary or branch, securities listed on an EU regulated market, or important relationships with companies subject to EU sustainability requirements, the European sustainability reporting framework may have a direct or indirect impact on your business.

The companies that prepare early will be better positioned to manage compliance, improve data quality, strengthen stakeholder confidence, and turn sustainability information into a source of strategic insight.

The future of sustainability reporting is increasingly global—and non-EU companies should be ready for it.
