EU sustainability directive and its impact on energy resilience
The European Union has tightened its rules on corporate responsibility for environmental and human rights harms across international supply chains. However, a debate is now emerging about whether the new framework could indirectly reduce Europe's ability to secure reliable energy supplies during crises or market disruptions.
The Corporate Sustainability Due Diligence Directive requires large companies to examine their operations and business relationships for serious environmental damage and labour abuses. Companies must then take steps to prevent or address those harms. The policy aims to extend accountability beyond a firm's own factories and offices.
Yet an opinion published in the Financial Times warns that strict interpretation of these obligations could make companies reluctant to buy from suppliers in politically sensitive or environmentally challenging regions. Some of those suppliers may be strategically important for energy infrastructure, critical minerals or fuel components. As a result, the directive could reduce procurement flexibility precisely when Europe needs it most.
This tension sits at the heart of EU policy. The bloc wants companies to avoid contributing to environmental destruction or human suffering abroad. At the same time, it needs dependable access to energy, raw materials and industrial components. Balancing those objectives requires careful implementation by both regulators and businesses.
Revised thresholds and obligations for covered companies
The directive applies to companies that employ more than 5,000 people and generate annual net worldwide turnover above €1.5 billion. Non-EU firms fall under the rules if they earn more than €1.5 billion in EU turnover. This scope is considerably narrower than the original proposal, which planned to cover businesses with as few as 1,000 employees and €450 million in turnover.
The European Commission simplified the directive through its Omnibus I package, adopted in February 2026. The changes reduce administrative demands on both regulated companies and their smaller suppliers. Firms are now expected to adopt a risk-based approach, focusing on serious impacts rather than requesting blanket information from every business partner.
Covered companies must identify, prevent and mitigate adverse impacts linked to their own operations, subsidiaries and chains of activities. They must also establish complaint procedures, monitor the effectiveness of their systems and communicate publicly about their actions. National authorities will enforce the rules rather than a single EU-level regime.
Penalties for serious violations can reach 3% of a company's net worldwide turnover. This financial exposure gives the directive considerable weight, even though it now applies to far fewer businesses than originally planned. Companies with significant purchasing power may still influence suppliers that are not directly covered.
Energy security risks from strict supply chain scrutiny
Europe's energy system depends on international supply chains for fuels, electricity infrastructure, critical minerals and industrial equipment. Some potential suppliers operate in jurisdictions with weak environmental safeguards, poor labour protections or difficult political relationships with the EU. Consequently, strict supply chain obligations could create several commercial and strategic risks.
Companies may avoid suppliers they consider legally or reputationally risky, even when alternatives are unavailable or more expensive. This behaviour could reduce procurement flexibility during shortages, geopolitical crises or sudden disruptions. Energy firms might have fewer options precisely when markets are most volatile.
Additional verification, contractual controls and remediation measures may increase procurement and project costs. Companies could postpone infrastructure projects while assessing complex upstream risks. If multiple firms abandon several suppliers simultaneously, Europe could become more dependent on a smaller number of approved sources.
Energy resilience often requires redundancy. A supply chain with several imperfect but usable sources can be more robust than one dependent on a limited number of suppliers that meet every sustainability criterion. Therefore, the directive's practical effect on procurement decisions matters as much as its formal legal scope.
The opposing view holds that unmanaged environmental and human rights risks can themselves threaten resilience. Pollution, labour abuses, corruption, conflict and community opposition can interrupt production, trigger litigation or cause governments to revoke permits. From this perspective, due diligence is not necessarily a constraint on security but a method of identifying vulnerabilities before they become supply disruptions.
How the Omnibus revisions reduced compliance burdens
The Omnibus changes appear to respond directly to concerns that sustainability rules were imposing disproportionate costs on European companies. The European Commission describes the revised approach as one intended to ensure that firms address serious impacts while avoiding unnecessary burdens for smaller business partners.
The narrowing of the scope is significant. Direct compliance will now focus on a relatively small group of very large companies. The risk-based approach should reduce blanket information requests across supply chains. Additionally, the revised rules extend the interval between regular due diligence assessments from one year to as much as five years in relevant circumstances.
The original framework included a requirement for large companies to adopt climate transition plans aligned with the Paris Agreement's 1.5°C objective. This obligation has been removed. National enforcement rather than a single EU-level civil liability regime now applies, giving member states more flexibility in implementation.
Nevertheless, the changes do not eliminate the underlying strategic issue. Large companies will still need to assess risks in their chains of activities and take action where serious adverse impacts are identified. Because those companies often have substantial purchasing power, their policies may continue to influence suppliers that are not legally covered.
Critical details on scope, penalties and implementation dates
- The directive requires companies to identify and address human rights and environmental impacts in their operations and chains of activities.
- EU companies are covered if they employ more than 5,000 people and generate over €1.5 billion in net worldwide turnover.
- Non-EU companies fall under the rules if they earn more than €1.5 billion in EU turnover.
- National authorities can impose penalties of up to 3% of a company's net worldwide turnover for serious violations.
- The amended legislation entered into force on March 18, 2026, with member states required to transpose it into national law by July 26, 2028.
- Companies generally must comply from July 26, 2029.
Balancing accountability with procurement flexibility
The concern raised in the Financial Times is not that environmental and human rights standards are incompatible with energy security. Rather, it highlights the risk of applying them without sufficient attention to supply concentration, emergency procurement and the availability of alternative suppliers.
The revised directive reduces that risk by limiting the number of directly regulated companies, extending implementation timelines and requiring a more targeted approach. Yet the rules may still influence broader commercial behaviour through contracts, audits and purchasing standards. The potential 3% worldwide turnover penalty may encourage companies to adopt conservative procurement policies, especially in sectors where supply chain failures could produce regulatory or reputational consequences.
A balanced approach would preserve the directive's core safeguards while allowing carefully controlled engagement with strategically important suppliers. This could include time-bound remediation plans, enhanced monitoring, emergency exemptions with clear accountability and coordination between sustainability, trade and energy security authorities.
National authorities will need to distinguish between serious, preventable abuses and risks that can be managed through remediation, monitoring or engagement. Companies, in turn, will need to avoid treating due diligence as an automatic reason to exit every difficult market. The effectiveness of the framework will therefore depend on implementation by both regulators and businesses.
For UK businesses that trade with the EU or operate as part of European supply chains, these rules may shape procurement decisions even though the UK is no longer a member state. Firms supplying EU companies above the threshold may face new contractual requirements or audit requests. Similarly, UK companies with substantial EU turnover may fall directly under the directive's scope.
