Scope 3 Transport Emissions Under CSRD: What Logistics Operators Need to Know

The Corporate Sustainability Reporting Directive (CSRD) significantly expands the scope of mandatory sustainability disclosure across the European Union. For logistics operators — and for the large enterprises that procure logistics services — transport emissions represent one of the largest and most technically challenging categories to report accurately.

What CSRD Requires

CSRD mandates that in-scope companies report their greenhouse gas emissions in line with the European Sustainability Reporting Standards (ESRS). For transport and logistics, this means reporting Scope 3 Category 4 emissions: upstream transportation and distribution.

The directive does not merely require a number. It requires organisations to disclose the data quality and methodology behind their calculations — distinguishing between primary activity data (actual measurements from real operations) and secondary data (industry averages and spend-based estimates).

Companies disclosing Scope 3 transport emissions based on generic GLEC default factors will be required to acknowledge the data quality limitations of that approach. As third-party assurance requirements tighten, the distinction between estimated and calculated emissions will become a material consideration.

The Data Quality Problem

Logistics operators serving large enterprise customers face a specific challenge: their customers need shipment-level carbon data to populate their own CSRD disclosures. A consolidated annual average across an entire fleet does not meet this requirement.

What enterprise customers increasingly need is CO2e data at the level of individual shipments — the carbon footprint of their specific cargo, on their specific routes, calculated from the actual conditions of each journey. This is a data quality requirement that most existing fleet carbon software is not designed to meet.

Primary Activity Data vs. Spend-Based Estimates

The GHG Protocol and ISO 14083 both establish a hierarchy of data quality for transport emissions calculations. Primary activity data — actual fuel consumption, actual route characteristics, actual load data — is preferred over distance-based estimates, which are in turn preferred over spend-based proxies.

For HGV fleets where CAN Bus telemetry and fuel card data are already collected, the inputs for primary-activity-based CO2e calculation exist. The question is whether the software processing that data applies the methodology required to produce primary-activity-grade outputs — or whether it is simply multiplying distance by an emission factor and calling the result a measurement.

What This Means for Logistics Operators

Logistics operators who can provide customers with high-quality, journey-level CO2e data will be better positioned as CSRD reporting requirements expand. The ability to demonstrate that carbon data is calculated from primary activity data — not estimated from population averages — is becoming a commercial differentiator.

Equally, logistics operators subject to CSRD in their own right will need to ensure that their internal Scope 1 and Scope 3 calculations meet the data quality standards the directive requires.
