An overview of the evolving EU ESG framework, its implications for organisations, and the strategic benefits for businesses operating in Greece

Updated: August 2026

Executive Summary: 5 Key Takeaways for Greek Organisations (EU ESG Framework 2026)

1. ESG is now embedded in EU business regulation, not optional reporting
Even with the 2026 Omnibus simplification, ESG requirements continue to shape corporate reporting, supply chains, finance, and consumer law across the EU.

2. Direct CSRD obligations are narrower, but indirect ESG pressure is expanding
Fewer companies are formally in scope, but SMEs and mid-sized Greek firms increasingly face ESG data requests from banks, customers, and multinational supply chains.

3. Social and governance factors are now core business risks, not HR or CSR issues
Labour conditions, human rights, board accountability, and internal controls are treated as material risks under EU frameworks such as CSRD, CSDDD, and related legislation.

4. ESG data quality and governance are becoming as important as financial reporting
Companies must be able to verify, trace, and justify sustainability data, especially under ESRS and assurance requirements introduced in Greek law (Law 5164/2024).

5. Non-compliance risk is increasingly reputational, contractual, and financial—not only legal
Greenwashing rules, supply-chain due diligence, and carbon-related mechanisms (CBAM, EUDR) mean ESG failures can directly affect market access, financing, and competitiveness.

Introduction: ESG Has Moved from Corporate Choice to Corporate Architecture

Environmental, Social and Governance — ESG — was once primarily associated with corporate reputation, voluntary sustainability reports and investor preferences. That era is rapidly disappearing.

Within the European Union, sustainability has become part of the regulatory architecture governing how companies report, finance, manufacture, purchase, employ people, manage supply chains and communicate with customers. The European approach is particularly significant because it does not treat sustainability merely as an environmental issue. It connects environmental performance with human rights, working conditions, business ethics, corporate governance, risk management, transparency and long-term corporate resilience.

For organisations operating in Greece, this development is especially important. Greece is fully integrated into the EU Single Market, while Greek companies increasingly depend on European banks, investors, multinational customers, export markets and supply chains. Consequently, even an organisation that is not directly subject to every ESG obligation may find itself indirectly affected by them through customers, lenders, insurers, investors or larger companies in its value chain.

The regulatory landscape has also changed significantly in 2025 and 2026. The EU’s Omnibus I simplification package has reduced the number of companies directly subject to mandatory sustainability reporting and narrowed certain due-diligence requirements. At the same time, the EU has continued to strengthen sustainability-related product, supply-chain, consumer-protection and financial-market rules. In July 2026, the European Commission also adopted revised European Sustainability Reporting Standards designed to simplify reporting while retaining the core sustainability information architecture. (EUR-Lex)

The conclusion is therefore not that every Greek company must produce a 100-page ESG report. The more important conclusion is this:

Every organisation should understand its ESG exposure and establish appropriate social and governance systems before regulation, customers or financing requirements force it to do so.

1. What Do We Mean by “Social Governance”?

The expression “social governance” is sometimes used interchangeably with the “S” and “G” elements of ESG. Strictly speaking, ESG consists of three interconnected dimensions:

● Environmental: climate change, emissions, energy, water, biodiversity, pollution, circular economy and resource use.

● Social: employees, health and safety, human rights, diversity, equality, communities, consumers and workers throughout the value chain.

● Governance: board responsibility, ethics, anti-corruption, risk management, internal controls, transparency, remuneration, compliance and accountability.

Social and governance issues cannot realistically be separated.

For example, a company may have an excellent environmental policy but still face serious ESG risks if:

● employees are not adequately protected;

● suppliers use forced or child labour;

● discrimination exists within the organisation;

● whistleblowing mechanisms are ineffective;

● the board does not understand sustainability risks;

● sustainability data cannot be verified;

● management makes unsupported “green” claims; or

● executives are rewarded for short-term performance while ignoring long-term sustainability risks.

The EU’s sustainability framework increasingly reflects this integrated approach. The CSRD/ESRS framework, for example, requires companies within scope to consider both the impacts that the organisation has on people and the environment and the way sustainability matters affect the organisation’s financial position, development and performance — the principle commonly known as double materiality. (Finance)

This makes ESG fundamentally a governance issue.

2. The EU Has Created an ESG Regulatory Ecosystem

There is no single “EU ESG Regulation.” Instead, a network of directives, regulations, delegated acts and standards has been constructed.

The principal pieces relevant to organisations include:

1. Corporate Sustainability Reporting Directive — CSRD.

2. European Sustainability Reporting Standards — ESRS.

3. Corporate Sustainability Due Diligence Directive — CSDDD.

4. EU Taxonomy Regulation.

5. Sustainable Finance Disclosure Regulation — SFDR.

6. ESG Ratings Regulation.

7. European Green Bond Standard.

8. Empowering Consumers for the Green Transition Directive.

9. Ecodesign for Sustainable Products Regulation and Digital Product Passport.

10. EU Deforestation Regulation.

11. Carbon Border Adjustment Mechanism — CBAM.

12. Related climate, circular-economy, environmental and supply-chain legislation.

13. The 2025–2026 Omnibus I simplification amendments.

These instruments do not all impose the same obligations on the same companies. Some apply directly to large companies, some to financial institutions, some to manufacturers or importers, and some primarily regulate products or financial markets.

Nevertheless, together they create a business environment in which ESG information, ESG controls and sustainability performance increasingly influence access to markets and capital.

3. CSRD: Sustainability Reporting Became Part of Corporate Reporting

The Corporate Sustainability Reporting Directive (Directive (EU) 2022/2464) was one of the most important changes in European corporate reporting.

The original CSRD significantly expanded sustainability reporting obligations and introduced the European Sustainability Reporting Standards. The first companies within its original scope reported for financial year 2024, with reports published in 2025. (Finance)

The reporting framework is important because sustainability information is no longer treated simply as marketing material. For companies within scope, it becomes part of the formal corporate reporting architecture.

The information can cover matters including:

● climate change;

● pollution;

● water and marine resources;

● biodiversity;

● resource use and circular economy;

● employees;

● workers in the value chain;

● affected communities;

● consumers and end-users;

● business conduct;

● corporate governance;

● policies and targets;

● sustainability risks and opportunities;

● due-diligence processes;

● greenhouse-gas emissions; and

● sustainability-related financial effects.

Greece: Law 5164/2024

Greece transposed the CSRD through Law 5164/2024, published in Government Gazette A’ 202/12 December 2024. The law amended the Greek corporate and accounting framework and introduced sustainability-reporting requirements, including requirements concerning assurance of sustainability information. (E-Nomothesia)

The OECD identifies Law 5164/2024 as the principal Greek law transposing the CSRD and notes that Greek sustainability disclosure is also connected with the Athens Exchange ESG Reporting Guide and the Greek Corporate Governance Code. (OECD)

This is an important development for Greek boards because sustainability is no longer simply the responsibility of a communications or marketing department.

It increasingly becomes a matter for:

the Board → senior management → risk management → finance → legal/compliance → HR → procurement → operations → internal controls.

4. The 2026 Change: The CSRD Scope Has Been Narrowed

It is important not to present the EU’s ESG rules as static.

In February 2026, the EU adopted Directive (EU) 2026/470, substantially amending the sustainability-reporting framework.

Under the revised framework, mandatory CSRD reporting is principally focused on undertakings exceeding both:

● €450 million net turnover, and

● 1,000 average employees.

(EUR-Lex)

This represents a significant reduction compared with the original CSRD scope.

It does not, however, mean that ESG has become irrelevant for smaller and medium-sized Greek companies.

Quite the opposite.

The revised rules introduce protections intended to prevent companies within the value chain from being subjected to disproportionate information requests. At the same time, the EU has developed voluntary sustainability reporting standards for smaller companies.

A smaller Greek company can therefore find itself outside direct mandatory CSRD reporting while still receiving sustainability-information requests from:

● a major Greek customer;

● an international customer;

● a bank;

● an investor;

● an insurance company;

● a multinational parent;

● a large supplier;

● a public-sector contracting authority; or

● another company subject to CSRD.

Direct regulatory scope and commercial ESG relevance are therefore two different things.

5. ESRS: From “Saying You Are Sustainable” to Demonstrating It

The European Sustainability Reporting Standards (ESRS) provide the detailed reporting architecture supporting the CSRD.

The original ESRS were established through Commission Delegated Regulation (EU) 2023/2772. In July 2026, the Commission adopted revised ESRS intended to simplify sustainability reporting and reduce administrative burden. (Finance)

This is significant because the EU is attempting to achieve two objectives simultaneously:

less unnecessary bureaucracy + more credible sustainability information.

For organisations, this means ESG governance should focus on data quality rather than simply producing attractive sustainability narratives.

A mature ESG system should allow management to answer questions such as:

● Where did this emissions number come from?

● Who owns the data?

● Which subsidiary supplied it?

● What methodology was used?

● Can the figure be reproduced?

● What evidence supports it?

● Who reviewed it?

● What happens if the number is wrong?

This is precisely why ESG increasingly resembles financial reporting.

6. The EU Taxonomy: Defining What “Sustainable” Means

The EU Taxonomy Regulation (EU) 2020/852 created a classification system for environmentally sustainable economic activities.

It covers six environmental objectives:

1. climate-change mitigation;

2. climate-change adaptation;

3. sustainable use and protection of water and marine resources;

4. transition to a circular economy;

5. pollution prevention and control; and

6. protection and restoration of biodiversity and ecosystems.

An activity must satisfy specific technical criteria and the “do no significant harm” principle to qualify as environmentally sustainable under the framework. (Finance)

The importance of the Taxonomy goes beyond reporting.

It provides a common language between:

companies + banks + investors + regulators + policymakers.

7. CSDDD: Sustainability Due Diligence Enters the Supply Chain

The Corporate Sustainability Due Diligence Directive (CSDDD), Directive (EU) 2024/1760, establishes obligations relating to human-rights and environmental impacts across value chains.

It has been amended by Directive (EU) 2026/470.

This means ESG performance increasingly depends on:

upstream → operations → downstream.

8. ESG Ratings Regulation

The ESG Ratings Regulation (EU) 2024/3005 introduces transparency requirements for ESG rating providers.

While it does not directly impose ESG ratings on all companies, it increases the importance of consistent ESG data for investor assessments.

9. SFDR: Why Financial Markets Care About ESG Data

SFDR applies primarily to financial institutions, but it drives ESG data demand across the economy.

Banks and investors increasingly require reliable sustainability information from companies they finance.

10. Greenwashing Is Becoming a Governance Risk

The Empowering Consumers for the Green Transition Directive (EU) 2024/825 strengthens rules against misleading environmental claims.

From 27 September 2026, companies must ensure sustainability claims are verifiable and substantiated.

11. Sustainable Products and Digital Product Passport

The Ecodesign for Sustainable Products Regulation (EU) 2024/1781 introduces the Digital Product Passport, making product sustainability data part of product identity.

12. EU Deforestation Regulation

The EUDR introduces strict traceability requirements for certain commodities, reinforcing supply-chain accountability.

13. CBAM: Carbon Becomes a Commercial Variable

CBAM introduces carbon costs into trade for selected sectors, directly affecting pricing and procurement decisions.

14. What Does All This Mean for a Greek Organisation?

ESG must be embedded into governance structures:

● Board oversight

● Executive accountability

● Financial integration

● HR and social governance

● Procurement controls

● Legal compliance

● Risk management

● Internal assurance

15. Why This Is Particularly Important for Greece

Greek companies face strong indirect ESG pressure through EU supply chains, finance, and export markets.

16. The Business Case: ESG as an Investment

ESG strengthens resilience, financing access, competitiveness, and operational efficiency.

17. What a Greek Organisation Should Do Now

Start with ESG governance assessment, focusing on:

● regulatory exposure

● supply-chain risks

● data quality

● governance ownership

● ESG integration into risk and finance

18. The Strategic Shift: From ESG Reporting to ESG Management

The key shift is from reporting compliance to embedded governance.

19. Practical ESG Action Checklist for Greek SMEs (Enhanced with Quick Wins + 90-Day Roadmap)

Even if a Greek SME is not directly in scope of CSRD or other major EU ESG regulations, it is increasingly exposed through customers, banks, and supply chains. The following enhanced framework adds prioritised quick wins and a structured 90-day implementation roadmap to the existing checklist.

19.1 ESG Quick Wins (0–30 Days: Low Cost, High Impact)

These actions can be implemented immediately with minimal resources and deliver fast improvements in ESG readiness:
