At a glance
- Tighter regulations: the CSRD requires large companies to report Scope 3 emissions from 2025 onward, while CountEmissionsEU harmonizes transport emission calculations under ISO 14083.
- Scope 3 dominates: indirect emissions (transport, distribution) account for roughly 75 % of a company’s total emissions — logistics is at the heart of the issue.
- Route optimization: the number-one lever, delivering a 15–25 % reduction in CO2 emissions and up to 20 % in fuel savings.
- Under-utilized truck capacity: average truck load factor is just 57 %, and 18 % of kilometres are driven completely empty.
- Competitive advantage: companies that get their carbon reporting in order ahead of schedule gain the upper hand in tenders.
Introduction
The carbon footprint of logistics is no longer a secondary indicator buried in a CSR report — it has become an operational and commercial criterion. Transport accounts for roughly a quarter of greenhouse gas emissions in Europe and remains, according to the European Environment Agency, one of the hardest sectors to decarbonize.
The landscape is shifting in 2025–2026. With the CSRD coming into force and the agreement on CountEmissionsEU, companies can no longer get by with rough estimates — they must measure, report, and reduce their emissions using harmonized methods.
For transport and delivery operators, the question is no longer why decarbonize, but how — in practical terms, with the tools available today.
1. The regulatory landscape: what is changing in 2025–2026
CSRD and Scope 3: logistics in the spotlight
Since January 2025, the CSRD directive requires large European companies to provide detailed emissions reporting — including Scope 3, which covers indirect emissions across the value chain. Scope 3 accounts on average for 75 % of total emissions. Transport and distribution (GHG Protocol categories 4 and 9) make up a significant share.
In plain terms: if you are a carrier or logistics service provider, your CSRD-bound clients will ask you for reliable, verifiable emissions data. This is no longer optional.
CountEmissionsEU: a single method for transport
The political agreement on CountEmissionsEU establishes a harmonized calculation method at European level, based on the ISO 14083:2023 standard. The approach is well-to-wheel, covers all transport modes, and favors primary data.
Publishing emissions remains voluntary — but if a company chooses or is required to disclose them, it must follow this framework. The European Commission plans to provide a free calculation tool tailored to SMEs.
2. Measuring the carbon footprint of your deliveries
Before you can reduce, you need to measure. Three approaches exist:
- Fuel-based: calculated from actual fuel consumption — the most accurate, but data-intensive.
- Activity-based: calculated from distance travelled, weight transported, and standard emission factors — more accessible, less granular.
- Hybrid: real data where available, standard factors for the rest — the most pragmatic compromise.
ISO 14083 provides the reference framework: well-to-wheel scope, emission factors by transport mode, and the option to use recognized databases where primary data is lacking.
The main challenge remains data quality, especially in multi-carrier contexts. When you work with five transport subcontractors, obtaining reliable fuel-consumption data for every trip is an uphill battle. This is where tools integrated into TMS (Transport Management Systems) come into their own.
3. Practical levers for cutting delivery CO2 emissions
Route optimization: the number-one lever
This is the most immediate and most measurable lever. According to NextBillion.ai, route optimization reduces CO2 emissions by an average of 15–25 %, with up to 20 % in fuel savings.
The principle is straightforward: fewer kilometres driven = less fuel consumed = less CO2 emitted. But the gains go beyond raw mileage — an optimization algorithm also eliminates detours, waiting times, and failed deliveries, all hidden sources of emissions.
Solutions like OCTAVE-ENGINE make this optimization accessible to SMEs and mid-sized companies: feed your stops, time constraints, and vehicle capacities into the algorithm, and get optimal route plans out — in seconds. Every kilometre saved is a verifiable carbon data point for your reporting.
Every unnecessary kilometre is a kilometre of CO2 emitted for nothing — and a kilometre that will have to appear in your next CSRD report.
Load optimization
The problem is massive and underestimated. According to ToolsGroup, the average truck load factor is just 57 % of capacity on loaded trips, and 18 % of kilometres are driven completely empty.
Optimizing loads — by consolidating orders, sharing return trips, and right-sizing vehicles — can have a dramatic impact. One documented case shows the elimination of 9,000 trucks per year, equating to 60,000 tonnes of CO2 avoided.
Fleet electrification
For urban distribution, electrification is advancing rapidly. Operating costs for electric vehicles are 20–50 % lower than for diesel equivalents in urban use. Amazon, with over 35,000 Rivian vans deployed, reports a 50 % reduction in GHG emissions compared with diesel.
But beware: a poorly routed electric vehicle wastes battery range needlessly. Route optimization becomes even more critical with an electric fleet, where every extra kilometre directly eats into remaining battery capacity.
Modal shift: from road to rail
Rail freight emits 80 % less CO2 per tonne-kilometre than road transport. For long-haul routes (beyond 700 km), shifting to rail is a powerful lever — even though rail still accounts for just 18 % of freight in Europe, compared with 72 % for road.
4. From measurement to competitive advantage
The CSRD is a constraint — but it is also a strategic opportunity. Companies that build their carbon reporting ahead of deadlines gain a tangible edge:
- Tenders: shippers subject to the CSRD increasingly demand carbon transparency from their transport providers. Being able to supply reliable emissions data is becoming a selection criterion.
- Commercial differentiation: all else being equal, a carrier that documents and reduces its emissions has a compelling argument.
- Virtuous circle: every optimized route delivers both a cost saving and a verifiable carbon data point — the same investment serves operational performance and CSR reporting.
Route optimization is not just a productivity tool — it is a compliance and competitiveness tool.
Key takeaways
The carbon footprint of logistics has moved from the realm of voluntary CSR to that of regulatory obligation and competitive advantage. The framework is in place (CSRD, CountEmissionsEU, ISO 14083), the tools exist, and the levers have been identified.
The most concrete and most immediate starting point remains route optimization: it delivers the fastest results, requires no heavy infrastructure investment, and generates data directly usable for carbon reporting.
Measure, optimize, report — that is the virtuous circle of logistics decarbonization.
