According to www.re-flow.io, the EU’s Corporate Sustainability Reporting Directive (CSRD) now requires companies to disclose not only their direct emissions but also their full value chain — particularly Scope 3 emissions, which typically represent 70–90% of a company’s carbon footprint.
What CSRD Requires for Scope 3
Under CSRD and its supporting European Sustainability Reporting Standards (ESRS), companies must:
- Disclose total GHG emissions, including Scope 1, 2, and Scope 3
- Describe the methodology, data sources, and assumptions used
- Perform a double materiality analysis — assessing both how climate affects the business and how the business impacts the climate
- Define emissions reduction targets, including actions taken across the value chain
This reporting must be structured, verifiable, linked to financial reporting, and ready for third-party assurance — moving far beyond annual CSR checklists.
Why Scope 3 Is Both Challenging and Critical
The source states that Scope 3 emissions span 15 categories defined by the Greenhouse Gas (GHG) Protocol, including purchased goods and services, transportation and distribution, use of sold products, end-of-life treatment, capital goods, and business travel and commuting. These categories make Scope 3 broad, complex, and highly variable between industries.
The challenges cited include:
- Data collection: Suppliers may lack emissions data or tools to share it
- Data quality: Many still rely on spend-based estimates (e.g., €1,000 on steel) rather than activity-based data (e.g., 500 kg of steel)
- Traceability: Without clear methods and sourcing, emissions data may not withstand external audits
- Complex supply chains: Especially in shipping, manufacturing, or construction
According to the report, Scope 3 compliance now directly affects regulatory compliance, financing decisions, and brand reputation. Investors evaluate supply chain emissions for ESG ratings; procurement teams increasingly request product-level carbon data; and misreporting can trigger penalties, reputational risk, or lost contract opportunities.
Implementation Timeline and Flexibility
The source states CSRD applies in phases:
- 2025: Large companies already covered by the Non-Financial Reporting Directive (NFRD)
- 2026–2028: Remaining large companies and listed SMEs, phased by size
On methodology, the report clarifies: “You can start with [spend-based estimates], but must disclose your methodology and improve quality over time. Activity-based data is preferred for accuracy and credibility.”
Practitioner Perspective: Actionable Readiness
For global supply chain professionals, this means supplier engagement is no longer optional — it’s foundational. Procurement, logistics, and sustainability teams must jointly establish traceable data pipelines, standardize carbon data requests (e.g., via EPDs or PCFs), and prioritize activity-based modeling where possible. Tools enabling digital supplier onboarding, automated LCA integration, and audit-ready documentation are becoming operational necessities — not just strategic advantages.
