Regulatory Context: The Urgency of Decarbonized Logistics

The European Union is increasing pressure on businesses to accelerate their ecological transition. Two regulations, the Corporate Sustainability Reporting Directive (CSRD) and the Carbon Border Adjustment Mechanism (CBAM), are positioned as major levers to transform logistics practices. While distinct in their objectives and application mechanisms, they converge towards the same goal: the deep decarbonization of the value chain. According to the European Environment Agency's (EEA) annual report, transport remains one of Europe's main greenhouse gas emitters, with a 1.5% increase in emissions in 2021 compared to 2020, highlighting the imperative for strong sectoral action.

For supply chain directors, transport managers, and CSR actors, mastering these mechanisms is no longer an option but a strategic necessity to ensure the competitiveness and resilience of their operations in a constantly evolving regulatory landscape. Understanding their specificities and interactions is crucial for a proactive and efficient approach.

CSRD: Extended Non-Financial Transparency Obligation

The Corporate Sustainability Reporting Directive (CSRD) is a European directive aimed at extending and strengthening sustainability reporting requirements for companies. Its main objective is to improve corporate transparency on their ESG (Environmental, Social, and Governance) impacts, including Scope 3 emissions, which encompass indirect emissions from the value chain, a large part of which is generated by logistics. Approximately 50,000 European companies will be affected by this directive, compared to 11,700 previously by the NFRD.

Scope and Timeline

CSRD applies progressively from January 1, 2024, for large companies already subject to NFRD. Large companies not subject to NFRD will be included from January 1, 2025, followed by listed SMEs from January 1, 2026. This means that even companies not directly affected will often have to provide sustainability data to their customers or partners subject to CSRD, de facto impacting the entire logistics chain. Reports will need to be audited and integrated into the annual management report.

Impacts on Logistics and Scope 3 Emissions

For logistics, CSRD entails the measurement, reporting, and reduction of greenhouse gas (GHG) emissions related to freight transport, identified as a major component of Scope 3. This includes upstream transport, movements between production sites, downstream transport to customers, and even emissions related to employee business travel. Precise and verifiable measurement according to recognized standards such as ISO 14083 or GLEC v3 is imperative. Without this granularity, companies will be unable to comply with the comprehensiveness required by the ESRS (European Sustainability Reporting Standards) in terms of emissions.

CBAM: A Carbon Border Adjustment Mechanism

The Carbon Border Adjustment Mechanism (CBAM) is a policy instrument aimed at equalizing the carbon price between domestic and imported products in the EU. Its objective is to prevent carbon leakage, where European industries would relocate their production to countries with less stringent climate policies to avoid the cost of EU ETS emission allowances. CBAM focuses on sectors considered carbon-intensive and at risk of carbon leakage.

Scope and Timeline

CBAM entered into force in a transitional phase on October 1, 2023, requiring importers to declare embedded emissions in their goods without any financial adjustment. The definitive phase, with the obligation to purchase CBAM certificates, will begin on January 1, 2026. Sectors currently covered are cement, iron and steel, aluminum, fertilizers, electricity, and hydrogen. The European Commission plans to extend the scope of CBAM to other sectors after an evaluation.

Links with Logistics and the Concept of Embedded Emissions

Indirectly, logistics is concerned by CBAM. Transport emissions related to the import of goods within the covered sectors are taken into account as an integral part of the embedded emissions in these products. Although direct transport emissions are not the primary focus of CBAM, their declaration is necessary for the overall calculation of the imported product's carbon footprint. This pushes importers to demand reliable and accurate data on freight emissions from their carriers, in line with ISO 14083 standards, to optimize their CBAM costs.

Synergies and Divergences: A Complementary Approach

The tables below summarize the main differences and synergies between CSRD and CBAM.

Characteristic	CSRD	CBAM
Main Objective	ESG transparency and decarbonization incentive	Avoid carbon leakage and equalize costs
Scope	All significant emissions (Scope 1, 2, 3) of companies	Embedded emissions of imported products (specific sectors)
Targeted Actors	Large companies, listed SMEs, subsidiaries	Importers of concerned products into the EU
Nature of Constraint	Reporting and non-financial audit obligation	Declaration and certificate purchase obligation
Direct Logistics Impact	Extended Scope 3 reporting, reduction obligation	Declaration of transport emissions for imported products

CSRD aims for a comprehensive transformation of companies by obliging them to report on their environmental, social, and governance impact, with logistics being a key contributor to Scope 3 emissions. It encourages route optimization, the choice of less carbon-intensive transport modes, and the integration of high-performing logistics providers. CBAM, on the other hand, acts as a financial lever, penalizing imports with a high carbon footprint and encouraging non-EU producers to decarbonize their manufacturing processes, which can potentially impact sourcing choices and logistics routes.

Operational Implementation: From Data to Decision

To effectively navigate between CSRD and CBAM, supply chain directors must adopt a strategy based on data, collaboration, and continuous optimization. Here are the key steps:

Audit current logistics emissions: Use recognized methods like ISO 14083 or GLEC v3 to precisely calculate CO₂ emissions for each transport segment (maritime, road, rail). Do not rely on generic averages, but on real data for fuel consumption, distance, and vehicle/vessel type. A study shows that using actual data can reduce the uncertainty of freight emission calculations by 15% to 40% compared to default values (ICLEI, 2014).
Identify emission hotspots: Analyze audit results to pinpoint the most emitting routes, transport modes, or logistics providers. For example, an 800 km road journey with an Euro VI truck will emit approximately 0.08 kg CO₂/t.km, while transoceanic maritime freight will often be less than 0.005 kg CO₂/t.km. Prioritize actions on the most significant segments.
Collaborate with supply chain partners: Demand verifiable emission data from your freight forwarders, maritime, and road carriers. For CBAM, this collaboration extends to non-European suppliers to accurately declare embedded emissions.
Optimize transport modes and routes: Seize the CSRD opportunity to reconfigure your logistics network. Favor modal shift to rail or inland waterways where relevant. For instance, rail freight emits up to 9 times less CO₂ than road transport for one tonne transported per kilometer (ADEME, 2021). Optimize container and truck filling.
Implement monitoring and reporting tools: Use a port-to-port orchestration cockpit integrating a CO₂ calculator compliant with standards. This not only allows for the collection of necessary data for CSRD and CBAM reporting but also to visualize emissions in real-time and make optimization decisions based on facts. Direct export of CSRD/CBAM reports should be possible.

Frequently Asked Questions

Q: Are CSRD and CBAM redundant? A: No, they are complementary. CSRD imposes broad transparency on all emissions (including logistics) for all large companies. CBAM is a targeted financial mechanism on imports of specific carbon-intensive products to prevent carbon leakage. Logistics data collected for CSRD can be used for the transport part of CBAM, but their objectives and scopes are distinct.

Q: How do I ensure my logistics emissions calculations are compliant? A: For CSRD, ISO 14083 and GLEC v3 standards are the references for calculating transport-related GHG emissions. They guarantee a harmonized and recognized methodology, essential for auditing sustainability reports. Using certified tools or those aligned with these standards is the best approach.

Q: Is my SME affected by these regulations? A: Directly, listed SMEs will be affected by CSRD from 2026. However, as a link in the value chain of large companies, you will likely be asked to provide emission data to your CSRD-subject customers, or your CBAM-subject importers. It is therefore strategic to prepare for it now.

Q: What is the concrete financial impact for my logistics? A: For CSRD, the impact is primarily related to compliance costs (data collection, tools, audit, decarbonization efforts). For CBAM, there will be a direct financial impact if you import products from the concerned sectors. The higher the embedded emissions (including transport), the higher the cost of CBAM certificates. As an indication, the average price of EU ETS allowances in 2023 was approximately €85/tonne of CO₂.
