The EU Sustainability Omnibus: What It Means in Practice

In recent years, the European Union has positioned itself as the global leader in corporate sustainability governance. Through instruments such as the Corporate Sustainability Reporting Directive (CSRD) and the Corporate Sustainability Due Diligence Directive (CSDDD), the EU sought to embed environmental and human-rights accountability into corporate operations and global value chains.

However, following intense debate among policymakers, industry, and investors, the EU’s Omnibus I simplification package has now been finalised. The reform significantly alters the scope and implementation of the EU’s sustainability framework.

While the Omnibus package is framed as a technical simplification aimed at reducing administrative burdens and strengthening European competitiveness, its implications extend far beyond compliance. Reflecting a broader recalibration in the EU’s regulatory approach to sustainability governance, the reforms highlight a recurring theme: the gap between policy ambition and operational implementation.

The Policy Context: From Regulatory Expansion to Strategic Recalibration

The EU’s original sustainability regulatory framework emerged from the European Green Deal and related initiatives aimed at aligning corporate activity with climate, environmental and social objectives.

Two directives formed the backbone of this framework:

1. Corporate Sustainability Reporting Directive (CSRD) requiring companies to disclose standardised information on environmental, social and governance impacts.
2. Corporate Sustainability Due Diligence Directive (CSDDD) requiring companies to identify, prevent and address human rights and environmental risks across their value chains.

Together, these instruments represented one of the most ambitious attempts globally to regulate corporate sustainability practices.

However, concerns quickly emerged regarding implementation costs, regulatory complexity, and the potential competitiveness impact on European firms. Business groups argued that the original framework imposed disproportionate reporting burdens, particularly on mid-sized companies.

These debates intensified following the publication of the Draghi report on European competitiveness, which warned that regulatory fragmentation and administrative complexity risked undermining the EU’s industrial base relative to competitors such as the United States and China.

Against this backdrop, the Omnibus package represents the EU’s response to mounting pressure to reconcile its sustainability ambition with economic competitiveness.

What the Omnibus Package Changes

The final Omnibus agreement substantially narrows the scope of the EU’s sustainability regulations, while introducing delays and simplifications in their implementation.

Corporate Sustainability Reporting Directive (CSRD)

Under the revised framework:

• CSRD will apply only to companies with more than 1,000 employees and annual turnover exceeding €450 million.
• Non-EU companies fall within scope only if they generate over €450 million in EU revenue.
• Smaller companies in value chains will be shielded from extensive reporting demands.

These changes are estimated to remove around 90% of companies from the directive’s scope.

In addition to narrowing the scope of covered entities, the Omnibus reforms also simplify the reporting architecture. The European Sustainability Reporting Standards (ESRS) will be streamlined, reducing the number of mandatory datapoints and reconsidering the role of sector-specific standards.

Together, these changes aim to reduce administrative complexity while maintaining the core objective of improving sustainability transparency among the largest market actors.

Corporate Sustainability Due Diligence Directive (CSDDD)

The Omnibus package similarly tightens the scope of due diligence obligations. Under the revised framework:

• Due diligence obligations apply only to companies with more than 5,000 employees and €1.5 billion in annual turnover.
• Implementation has been delayed until July 2029.
• Provisions for an EU-wide civil liability have been removed, with penalties capped at 3% of global turnover.
• The original requirement for companies to adopt mandatory climate transition plans has been dropped.

The directive’s due diligence expectations have also been narrowed in practice. The revised framework focuses primarily on direct business partners, rather than requiring companies to systematically assess risks across their entire value chains.

Taken together, these changes represent a substantial shift from the original design of the directive. Rather than a broad-based regulatory model applying across corporate Europe, sustainability governance obligations are now focused almost exclusively on the largest multinational companies.

Regulatory Simplification or Strategic Shift?

At face value, the Omnibus package represents a regulatory simplification exercise. However, viewed more closely, it reflects a deeper recalibration of the EU’s sustainability strategy.

The original regulatory framework sought to drive systemic change across corporate Europe, by embedding ESG governance into a large share of companies. The Omnibus reforms instead concentrate obligations on a relatively small number of large firms while encouraging voluntary or market-driven adoption among others. In effect, the EU has moved from a model of broad regulatory coverage towards a more concentrated compliance framework focused on major market actors.

This shift is partly driven by competitiveness concerns. European policymakers have become increasingly aware that stringent reporting requirements risk placing EU firms at a disadvantage relative to competitors operating in jurisdictions with lighter regulatory regimes.

At the same time, critics argue that narrowing the regulatory perimeter undermines the EU’s ambition to lead global sustainability governance. Environmental groups and investors have warned that reduced disclosure requirements may weaken transparency and make it harder to assess how effectively companies are managing environmental and social risks.

Whether the Omnibus reforms represent a pragmatic recalibration or a dilution of sustainability ambition remains a matter of debate.

From Regulation to Market Expectations

Despite the narrowing of formal regulatory obligations, sustainability risk itself has not diminished.

Companies operating globally continue to face a complex landscape, including:

• investor scrutiny and ESG disclosure expectations
• trade restrictions and import bans linked to human rights or environmental harm
• supply chain disruptions linked to environmental or social controversies
• reputational exposure and consumer pressure.

In practice, many firms that now fall outside the formal scope of CSRD or CSDDD will still encounter sustainability reporting expectations from:

• lenders and investors
• large corporate customers
• procurement standards
• international regulatory frameworks.

For companies integrated into global supply chains, these market pressures can often be as significant as legal obligations.

Over more than a decade of working with companies across commodities and geographies, TDi has consistently seen that organisations that proactively understand and manage supply chain risks are better positioned to protect their reputation, secure market access and strengthen long-term resilience.

The Supply Chain Dimension

One of the most important implications of the Omnibus reforms lies in how sustainability governance will operate across supply chains.

Even though smaller firms may fall outside the formal regulatory scope, many will still be indirectly affected through their relationships with large multinational companies that remain subject to due diligence obligations.

Large companies will continue to require information from suppliers in order to meet their own risk management and disclosure requirements. However, the Omnibus package explicitly limits the extent to which these requests can impose administrative burdens on SMEs.

This creates a more complex dynamic. Sustainability oversight will increasingly operate through value-chain relationships, with large firms acting as transmission mechanisms for due diligence expectations across their supplier networks.

In this sense, the Omnibus reforms do not eliminate sustainability governance pressures. Instead, they shift the centre of gravity from regulatory compliance across many firms towards risk-based management driven by large corporate actors and their value chains.

The Strategic Implications

The Omnibus reforms therefore raise an important strategic question for companies:

Does falling outside regulatory scope change the underlying sustainability risk landscape?

In most cases, the answer is no.

Environmental and human-rights risks embedded in supply chains remain unchanged. Nor have the underlying drivers of sustainability governance disappeared, including:

• climate transition pressures
• responsible sourcing requirements
• geopolitical supply chain shifts
• the imperative to gain social license to operate
• investor ESG expectations.

For companies now outside the formal regulatory perimeter, the Omnibus reforms effectively provide time rather than exemption.

This time can be used to build proportionate governance systems, strengthen risk identification processes, and align internal reporting frameworks with evolving global standards.

What Happens Next?

Looking ahead, three trends are likely to shape how the Omnibus reforms play out in practice.

1. Sustainability governance will increasingly focus on large multinationals

By design, the Omnibus reforms shift responsibility for sustainability reporting and due diligence toward a small number of very large firms. In practice this means that the effectiveness of the EU’s sustainability framework is likely to depend less on how many companies fall within scope and more on how rigorously firms implement and enforce governance.

2. Market pressure will continue to drive voluntary adoption

Even where regulatory requirements fall away, companies may maintain sustainability reporting due to investor expectations and supply chain requirements. Reporting in the spirit of these regulations can also help companies to proactively respond to civil society and public reputational concern.

3. Implementation will determine real-world impact

As with many regulatory initiatives, the effectiveness of the Omnibus framework will ultimately depend less on the legislation itself and more on how it is implemented by companies, regulators and markets.

These dynamics echo a broader lesson in sustainability governance: setting policy direction is only the first step. Translating policy ambition into operational reality remains the true challenge.

Conclusion

The EU’s Omnibus package represents a significant recalibration of the trading bloc’s sustainability framework.

While the reforms reduce regulatory coverage and administrative burdens, they do not remove the underlying environmental and human rights risks embedded in global supply chains.

Instead, the reforms shift the architecture of sustainability governance. Rather than applying uniform obligations across a broad range of companies, the EU framework now concentrates responsibility among large multinational firms whose influence extends across global value chains.

For companies operating in European markets, the key question is therefore not simply whether they remain within scope of the directives, but how sustainability governance continues to shape their access to markets, capital and partnerships.

As with critical mineral policy and other strategic regulatory initiatives, the ultimate impact of the Omnibus reforms will depend less on the legislative text itself and more on the practical decisions companies make in response.
