Logistics Insights & Trends

Sustainable Transport Modes: 

Driving the Transition to Low-Carbon Logistics

Executive Summary

Transportation accounts for the largest share of logistics-related emissions, making the choice of transport mode one of the most important decisions in any decarbonization strategy. Across Europe, policymakers and industry leaders are increasingly promoting a shift toward more sustainable transport modes that reduce greenhouse gas emissions, improve energy efficiency and strengthen supply chain resilience. The European Union's Sustainable and Smart Mobility Strategy and TEN-T policy place particular emphasis on rail freight, multimodal transport, alternative fuels and cleaner mobility solutions.

For logistics companies, sustainable transport is no longer simply an environmental initiative

—it is becoming a competitive advantage that supports ESG commitments, customer requirements and long-term cost optimization.

Driving the Transition to Green Logistics

Executive Summary

Transport accounts for a significant share of logistics-related emissions, making sustainable transport modes one of the most important levers for achieving decarbonisation goals. The European Union's Sustainable and Smart Mobility Strategy promotes a shift toward cleaner, more efficient and lower-emission transport solutions through modal shift, alternative fuels, digitalisation and multimodal logistics integration.

For logistics organisations, sustainable transport is no longer solely an environmental consideration. It has become a strategic priority that influences operational costs, customer expectations, ESG performance, regulatory compliance and long-term competitiveness. 

Why Sustainable Transport Matters

Global supply chains depend heavily on freight transportation, yet traditional road-based logistics generates significant greenhouse gas emissions.

As a result, governments, customers and investors are increasingly demanding:

• Lower carbon emissions
• Reduced fuel consumption
• Improved energy efficiency
• Greater transparency in transport performance
• More sustainable logistics networks

Benefits of Sustainable Transport

✅ Reduced carbon footprint

✅ Lower operating costs

✅ Improved ESG performance

✅ Better regulatory compliance

✅ Increased supply chain resilience

✅ Enhanced customer reputation

✅ Access to sustainability funding

1. Rail Freight: 

The Backbone of Sustainable Logistics

Rail transport is widely recognised as one of the most environmentally efficient freight transport modes available.

Why Rail Matters

Rail systems can move large volumes of freight over long distances with significantly lower emissions than road transport while reducing congestion on major transport corridors. The European Commission continues to promote rail freight through TEN-T development and sustainable mobility policies. [gouvernement.lu], [aifactory.lu]

Advantages

• Lower CO₂ emissions
• High transport capacity
• Reduced road congestion
• Improved energy efficiency
• Enhanced long-distance freight performance

Luxembourg Opportunity

Luxembourg's strategic location and facilities such as the Bettembourg intermodal terminal position the country strongly for rail-road integration and cross-border freight solutions.

2. Multimodal Transport

Multimodal transport combines multiple transport modes within a single supply chain journey.

Common Combinations

• Rail + Road
• Air + Road
• Rail + Inland Waterway
• Sea + Rail + Road

Rather than relying on a single mode, multimodal solutions optimize both cost and environmental performance. The EU identifies multimodal transport as a critical element of future sustainable freight systems. [gouvernement.lu], [list.lu]

Benefits

✅ Reduced emissions

✅ Increased flexibility

✅ Better capacity utilisation

✅ Improved resilience

✅ Lower dependency on one transport mode

3. Electric Road Freight

Electrification is transforming urban and regional freight transport.

Applications

Last-Mile Delivery

Electric vans are increasingly used for:

• E-commerce deliveries
• Urban distribution
• Retail logistics

Regional Transport

Battery-electric trucks are gradually expanding into medium-range freight operations.

Benefits

• Zero tailpipe emissions
• Lower energy costs
• Reduced maintenance
• Improved urban air quality
• Reduced noise pollution

The EU continues to support charging infrastructure and zero-emission transport investments through various transport and climate programmes. [guichet.public.lu], [oliverwyman.com]

4. Hydrogen-Powered Freight

Hydrogen is increasingly viewed as a key solution for long-distance freight transport where battery-electric solutions may face operational constraints.

Potential Applications

• Long-haul trucking
• Heavy freight transport
• Logistics corridors
• Port and terminal operations

The European Hydrogen Bank and Innovation Fund continue to support hydrogen deployment across industry and transport sectors. [maersk.com], [europarl.europa.eu], [nshift.com]

Advantages

✅ Fast refuelling

✅ Long driving ranges

✅ Zero tailpipe emissions

✅ Suitable for heavy-duty transport

5. Sustainable Aviation

Air freight remains essential for high-value, time-sensitive and pharmaceutical supply chains. However, aviation faces significant decarbonisation challenges.

Sustainable Aviation Fuel (SAF)

SAF is currently considered one of the most important solutions for reducing aviation emissions.

Additional Measures

• Aircraft efficiency improvements
• Ground operation electrification
• AI-enabled flight optimisation
• Better cargo load planning

The Innovation Fund increasingly supports sustainable aviation projects and low-emission mobility initiatives. [oliverwyman.com], [savillsim.com]

Relevance for Luxembourg

Given Luxembourg's role as a leading European air cargo hub, sustainable aviation represents a major strategic opportunity.

6. Inland Waterways & Maritime Transport

Waterborne transport can provide highly efficient freight solutions for specific cargo categories.

Benefits

• High-volume transportation
• Lower emissions per tonne-kilometre
• Reduced road congestion
• Strong sustainability performance

Emerging Trends

• Low-carbon vessels
• Alternative maritime fuels
• Electrified port operations
• Green shipping corridors

The EU is increasingly supporting maritime decarbonisation through dedicated funding initiatives. [maersk.com], [oliverwyman.com]

7. Urban Logistics & Micro-Mobility

Cities are becoming testing grounds for innovative sustainable transport solutions.

Emerging Approaches

Cargo Bikes

Used increasingly for:

• Last-mile deliveries
• City-centre logistics
• Parcel distribution

Urban Micro-Hubs

Small consolidation centres located near city centres reduce delivery distances and vehicle traffic.

Benefits

✅ Reduced congestion

✅ Lower emissions

✅ Faster urban deliveries

✅ Improved citizen experience

8. Digitalisation as an Enabler of Sustainable Transport

Technology plays a critical role in making transport systems more sustainable.

Key Technologies

Artificial Intelligence

• Route optimisation
• Fuel consumption reduction
• Fleet utilisation improvement

Predictive Analytics

• Demand forecasting
• Capacity planning
• Congestion prediction

Digital Twins

• Transport network simulation
• Modal shift modelling
• Infrastructure planning

These technologies help logistics providers optimise both carbon performance and operational efficiency. [aircargonews.net], [gartner.com], [wns.com]
