How CSRD’s Double Materiality Requirement Affects Companies – Large and Small

Under the Corporate Sustainability Reporting Directive (CSRD), the concept of double materiality is one of the most significant changes compared to previous reporting frameworks. For companies, double materiality introduces new complexities — particularly when it comes to tracking emissions and environmental impact across the supply chain.

When most people hear about the Corporate Sustainability Reporting Directive (CSRD), they assume it only applies to the biggest corporations. Since the EU’s Omnibus I simplification entered into force on 18 March 2026, that is largely true for the reporting obligation itself – but the effects still reach far beyond those companies:

  • Financial years 2024–2026: Large public-interest companies with more than 500 employees have reported since financial year 2024. Those below the new thresholds fall out of scope from financial year 2027, and Member States may exempt them already for 2025 and 2026.
  • From financial year 2027: Companies with more than 1,000 employees and a net turnover above €450 million report.
  • Listed SMEs: no longer covered by mandatory CSRD reporting. They can report voluntarily using the EU’s voluntary standard for SMEs (VSME).

Source: Directive (EU) 2026/470 (Omnibus I). EU Member States must transpose the changes into national law by 19 March 2027.

But here’s the catch: companies outside the scope can still be asked for data. Large companies that report must cover their value chain – including the Scope 3 emissions of subcontractors, logistics partners and suppliers.

Omnibus I sets a limit: partners with up to 1,000 employees cannot be required to provide more than the EU’s voluntary SME standard (VSME) covers, and they must be told when a request goes beyond it. But the VSME’s basic module already includes total energy consumption – with fuels split into renewable and non-renewable – and Scope 1 and 2 greenhouse gas emissions (Commission Recommendation (EU) 2025/1710). In other words: even if you’re not required to report, your customers can still ask for your fuel use and emissions.

For both large corporations and smaller hauliers, logistics firms, or suppliers, this makes understanding double materiality and value chain emissions essential — today, not tomorrow.

For the full framework connecting Scope 1, 2, and 3 emissions to CSRD reporting, SBTi targets, and Proof of Sustainability documentation, see our complete guide to emissions reporting.

What is Double Materiality?

Double materiality requires companies to assess and report on two dimensions of sustainability performance:

  1. Impact Materiality – How the company’s activities affect the environment and society.
  2. Financial Materiality – How sustainability risks and opportunities (e.g., climate change, regulatory shifts) impact the company’s financial health and performance.

This means reporting is no longer limited to direct emissions and operational performance — it extends to the entire value chain, including the environmental and financial consequences of third-party suppliers and subcontractors.

What Does This Mean for your company?

Large corporations, haulers and logistics providers are in a unique position because their environmental impact is not only driven by their own fleet and operations (Scope 1 and Scope 2) but also by the broader transport ecosystem — including the subcontractors and transport partners they work with (Scope 3).

Scope 3 emissions represent the most complex and significant challenge under the CSRD for companies because they include emissions from subcontractors and third-party partners.

Scope 3 emissions include:
• Emissions from transport subcontractors you hire to carry goods.
• Fuel consumption from third-party transport providers.
• Emissions from upstream suppliers (e.g., fuel producers).
• Lifecycle emissions of the vehicles in your fleet.
• End-of-life emissions from scrapping vehicles or equipment.
• Business travel and employee commuting.

Example:
If you subcontract a third-party logistics company to deliver goods, the emissions from their trucks will count as your Scope 3 emissions under the CSRD.

Why Scope 3 emissions are critical

If your subcontractors use fossil fuels or operate inefficient fleets, their emissions are reflected in your overall sustainability report.

Tracking Scope 3 emissions requires collaboration across the supply chain. You need accurate data from subcontractors on fuel consumption, emissions factors, and transport volumes.

Example:
If you hire a subcontractor for last-mile delivery, you’ll need to gather data on the type of fuel they use, distance travelled, and load weight — and then integrate that into your sustainability report.

Even if your company isn’t directly required to publish a CSRD report yet, you may already feel the effects because:

  • Large customers must report Scope 3 emissions (value chain emissions).
  • This includes emissions from subcontracted hauliers, logistics partners, and suppliers.
  • Partners with up to 1,000 employees can be asked for the data the voluntary SME standard covers – including fuel and energy use and Scope 1 and 2 emissions.
  • Tenders may start including requirements for fossil-free fuels like HVO100.

In other words: smaller companies feel CSRD through customer contracts – within the limits Omnibus I now sets.

How Companies Can Meet Scope 3 Reporting Requirements

Scope 3 reporting may feel overwhelming — especially for transport and logistics companies where subcontractors play such a big role. But with the right approach, tools, and partnerships, it’s possible to turn this complex task into a structured process that delivers both compliance and competitive advantage.

Use Renewable Fuels Like HVO100
Switching to renewable fuels like HVO100 can significantly reduce Scope 1 and Scope 3 emissions.
• HVO100 reduces lifecycle emissions by up to 86% compared to fossil diesel*.
• Subcontractors using HVO100 will contribute lower emissions to your overall Scope 3 profile.

* Based on 2025 verified delivery data. Actual reduction per delivery ranges from 57% to 121% depending on feedstock composition and certified batch. Calculated per the RED III well-to-wheel life-cycle methodology using ISCC-certified mass balance allocation. Proof of Sustainability (PoS) documentation available on request.

Engage with Subcontractors Early
• Establish emissions reporting standards for all subcontractors.
• Include emissions reporting requirements in subcontractor contracts.
• Encourage subcontractors to switch to renewable fuels and vehicles with documented lower emissions.

Invest in Emissions Tracking Tools
• Use platforms like Biofuel Express Insight to track and measure emissions from subcontractors and direct operations.
• Provide subcontractors with guidance on how to collect and report accurate emissions data.

Partner with Certified Suppliers
• Choose subcontractors and fuel providers that can document their emissions data.
• Partner with suppliers certified under recognised sustainability standards (e.g., ISCC).

Start Early and Build a Framework
• Establish an internal emissions tracking framework.
• Start with pilot projects to refine data collection and reporting methods.
• Develop an emissions reduction roadmap aligned with CSRD requirements.
