Decarbonation, scope 3, and CSRD
Reducing your transport carbon footprint: scope 3 and CSRD
Freight transport weighs heavily in a company's scope 3 (indirect emissions). Reducing it runs through the choice of mode (ocean emits far less than air per tonne-kilometer, rail less than road), optimizing load factor and lanes, and diversifying toward low-carbon solutions. To measure and report it (CSRD), you need reliable, traceable emissions data per shipment - which few freight forwarders provide yet. A forwarder able to produce usable CO2 reporting becomes an asset for compliance and differentiation.
Decarbonizing transport is no longer a communication topic: it has become a B2B purchasing criterion and, with CSRD, a reporting obligation. Freight transport represents a significant share of companies’ scope 3 - and it is one of the hardest items to measure. The good news: it is also a field for action and differentiation still little exploited by freight forwarders.
Reducing: the concrete levers
Before measuring, you can already act:
- The choice of mode. Per tonne-kilometer, ocean emits far less than air, and rail far less than road. Shifting to air only what is genuinely urgent sharply reduces the footprint.
- Load factor. A well-loaded full container is more efficient than several fragmented shipments. Consolidating orders pays off.
- Lanes. Rationalizing routes and limiting unnecessary transshipment.
- Multimodal. Integrating rail on lanes where it offers a good transit-time/footprint compromise (notably Asia-Europe).
Measuring: the real challenge of scope 3
Scope 3 covers indirect emissions, including upstream and downstream transport. Measuring it requires per-shipment data, calculated with a recognized methodology (GLEC framework, ISO 14083 standard) from mode, distance, weight, and load factor. The difficulty is not the formula - it is documented - but obtaining reliable, traceable data, shipment by shipment. This is precisely what is missing when you work with a freight forwarder that does not produce these figures.
CSRD: anticipate rather than scramble
The CSRD directive requires reporting environmental impacts, including transport emissions. Compliance rests on reliable, consistent, and auditable data over time. Concretely: centralize your shipments’ emissions, rely on a recognized methodology, and choose partners able to provide this data. Companies that get ahead of it avoid the year-end scramble for data - and those that wait until the last minute often discover that their providers cannot give it to them.
The freight forwarder, a link in compliance
Still few freight forwarders provide usable CO2 reporting. Yet it is becoming a selection criterion in its own right in Europe. When you evaluate a partner, ask: do you calculate emissions per shipment? With which methodology? In what usable format? A forwarder like OVRSEA, which integrates carbon data into the platform, turns a regulatory constraint into an asset: emissions are calculated per shipment and aggregated into an annual total in tCO2e, ready for CSRD obligations, and an environmental score from A to E is shown on each quote to make the impact visible at the moment of decision, not only at year-end. Exportable, reliable figures plus concrete levers to actually reduce the footprint.
FAQ
How do I reduce CO2 emissions from ocean freight?
Several levers: favor ocean or rail where possible (far less emitting than air and road per tonne-kilometer), optimize load factor (a well-loaded FCL rather than multiple LCLs, consolidating shipments), rationalize lanes, and decide mode by mode based on real urgency. Shifting to air only what is truly urgent sharply reduces the footprint.
How do I measure scope 3 emissions from my shipping?
Scope 3 covers indirect emissions, including upstream and downstream transport. Measuring it requires per-shipment emissions data, calculated with a recognized methodology (GLEC, ISO 14083) from mode, distance, weight, and load factor. The difficulty is not the formula but obtaining reliable, traceable data - this is where an equipped freight forwarder makes the difference.
Does my freight forwarder report carbon emissions?
Still few forwarders provide usable and auditable CO2 reporting. Yet it is a rising selection criterion in Europe. Ask whether the forwarder calculates emissions per shipment, with which methodology, and in what format (export, dashboard). Reliable reporting saves you from rebuilding this data by hand for your non-financial obligations.
How do I make my supply chain CSRD compliant?
CSRD requires reporting environmental impacts, including transport emissions (scope 3). Compliance rests on reliable, traceable, and consistent data over time. Concretely: centralize your shipments' emissions data, rely on a recognized methodology, and work with partners able to provide these figures. Anticipating avoids the year-end scramble for data.
Is rail freight greener than ocean or road?
Per tonne-kilometer, rail is markedly less emitting than road and air, and complementary to ocean on certain lanes (notably Asia-Europe). It offers a good transit-time/footprint compromise between slow ocean and very emitting air. Its value depends on the lane and availability; a multimodal freight forwarder can put it in the equation.
