What is sustainable freight transport?

Sustainable freight transport: definition

Sustainable freight transport refers to logistics systems designed to balance economic, social, and environmental needs. This approach combines innovative practices and technologies to improve efficiency, lower emissions, and ensure fairness across the supply chain.

The freight industry is a cornerstone of global trade. By adopting eco-friendly technologies and optimising operations, freight transport minimises its carbon footprint, reduces costs, and supports international efforts to achieve decarbonisation.

Solutions like green logistics and the TIR system – a globally recognised tool for streamlining customs transit – play a key role in fostering sustainable freight.

To better understand sustainable freight transport, it is essential to explore its three pillars: economic, social and environmental sustainability, which collectively define its long-term success.

Economic sustainability

Economic sustainability ensures that freight systems remain viable while supporting trade and commerce. A major focus is the optimisation of supply chain logistics, which reduces inefficiencies and operational costs. By leveraging energy-efficient vehicles and smarter infrastructure, companies can lower fuel consumption and minimise delays.

For instance, the use of intermodal transport, which integrates road, rail and sea freight, has proven to reduce costs and improve reliability. Additionally, governments and organisations are encouraging greener logistics through policies, incentives and technology adoption, including alternative fuels and route optimisation systems.

This approach ensures that sustainable freight transport drives economic growth without compromising future opportunities for profitability.

Social sustainability

Social sustainability addresses the human impact of freight transport, from labour practices to community well-being. Freight systems should ensure fair working conditions, promote safety, and reduce urban congestion caused by logistics operations.

Urban freight, for example, is a growing concern due to its effect on city residents. Innovations in last-mile delivery systems are helping to alleviate traffic and improve urban mobility. Similarly, investments in driver training and safety technologies ensure better working conditions for operators while reducing risks for pedestrians and other road users.

By fostering equitable and safe logistics systems, social sustainability supports communities while maintaining the efficiency of the freight sector.

Environmental sustainability

The most pressing challenge for sustainable freight transport is further reducing its environmental impact, particularly in terms of CO2 emissions.

Solutions include adopting renewable energy sources such as electric- and hydrogen-powered vehicles, as well as energy-efficient technologies like smart logistics systems and aerodynamic designs.

Investments in green infrastructure, such as electrified railways and renewable-powered ports, further advance environmental goals. Together, these strategies align the freight industry with global climate action objectives while maintaining operational efficiency.

What is the most sustainable freight transport?

Determining the most sustainable freight mode requires analysing factors such as distance, cargo type and available infrastructure. While each mode –road, rail, sea, and air –has unique advantages, their sustainability levels vary.

Comparing different modes: road, rail, sea and air

  • Road transport is crucial for last-mile deliveries. Recent innovations in carbon-neutral, electric- and hydrogen-powered trucks are reducing its carbon emissions.
  • Electrified rail networks can improve environmental performance, making it an important part of sustainable logistics.
  • Sea freight is another sustainable option, particularly for global trade. Cleaner fuels, including LNG and wind-assisted propulsion, are helping the maritime industry transition towards greener practices.
  • Air freight, while the fastest, is the least sustainable mode due to its high carbon footprint. Despite advances in fuel efficiency and the development of sustainable aviation fuels, air transport is generally limited to high-value, time-sensitive goods.

How intermodal freight can enhance sustainability

Intermodal freight transport, which integrates multiple modes within a single logistics chain, is a cornerstone of sustainable freight systems. By combining the strengths of road, rail, and sea, intermodal solutions minimise emissions and reduce reliance on less sustainable modes.

For example, goods can travel long distances via rail or sea and transfer to trucks for last-mile delivery, significantly cutting overall emissions. This approach maintains flexibility while enhancing efficiency, making it a key strategy for decarbonising logistics.

Intermodal systems also benefit from advancements in digital logistics technologies. Tools like route optimisation software and real-time cargo tracking improve resource use, reduce transit times, and lower operational costs –all while reducing the environmental footprint.

Governments and private sectors are investing heavily in intermodal infrastructure, such as freight corridors and logistics hubs, to facilitate the seamless movement of goods between modes. Policies encouraging the use of rail and sea over road transport are further accelerating the transition to intermodal systems. Ultimately, intermodal freight transport, supported by technology and regulatory frameworks, offers a scalable solution to improve sustainability across global supply chains.
