How Does Intermodal Fit Into Shipper Sustainability Strategies

What is intermodal transportation and how does it differ from traditional shipping methods?

Intermodal transportation is a shipping method that involves using two or more modes of transport to move goods from origin to destination. Unlike traditional shipping methods that rely on a single mode, such as truck-only or rail-only, intermodal utilizes a combination of truck, rail, and sometimes ship to optimize transport efficiency and cost.

Key Differences Between Intermodal and Traditional Shipping

Containers: Intermodal shipping uses standardized containers that can be easily transferred between modes without the need to handle the goods themselves. Traditional methods often require loading and unloading goods when changing modes.

Infrastructure: Intermodal leverages existing transportation networks and infrastructure, including railroads, highways, and ports. Traditional shipping may be more limited in terms of infrastructure options.

Efficiency: By using multiple modes, intermodal can take advantage of the strengths of each – the flexibility of trucks for short hauls and the efficiency of rail for long distances. This makes intermodal more efficient overall compared to traditional single-mode transport.

Cost: Intermodal is often more cost-effective than traditional shipping, especially for long-haul routes, due to the efficiency gains from using rail for a significant portion of the journey.

Environmental Impact: Intermodal is generally more environmentally friendly than truck-only shipping, as rail and ship produce lower emissions per ton-mile than trucks.

Characteristic	Intermodal	Traditional
Modes Used	Multiple (truck, rail, ship)	Single (truck, rail, or ship)
Handling	Standardized containers	Individual handling of goods
Efficiency	Optimized for each leg	Limited by single mode
Cost	Often lower, especially long-haul	Higher for long distances
Emissions	Lower per ton-mile	Higher, especially truck-only

Intermodal transportation’s use of multiple modes, standardized containers, and optimized routing distinguishes it from traditional shipping methods. These differences enable intermodal to offer greater efficiency, lower costs, and reduced environmental impact for many shipping scenarios.

How can intermodal shipping contribute to a company’s sustainability goals?

Intermodal shipping can play a significant role in supporting a company’s sustainability goals by reducing the environmental impact of freight transportation. Here are several key ways intermodal contributes to sustainability:

Lower Emissions

Rail and ship transportation, which are major components of intermodal shipping, generate significantly lower emissions per ton-mile compared to truck-only shipping. For example:

• Rail emits 5.4 pounds of carbon dioxide (CO2) per 100 ton-miles
• Trucks emit 19.8 pounds of CO2 per 100 ton-miles

By shifting a portion of the journey from truck to rail, intermodal can substantially reduce a shipment’s carbon footprint.

Reduced Energy Consumption

Intermodal is more fuel-efficient than truck-only shipping. Trains can move one ton of freight approximately 479 miles on a single gallon of fuel, compared to about 145 miles by truck. This efficiency translates to energy savings and reduced dependence on fossil fuels.

Congestion Mitigation

Intermodal shipping can help alleviate highway congestion by shifting freight to rail, which has a much higher capacity than trucks. A single train can remove several hundred trucks from the road, reducing traffic and the associated environmental impacts of congestion.

Improved Air Quality

By reducing emissions and congestion, intermodal shipping contributes to improved air quality. This is particularly important in urban areas and port communities that are disproportionately affected by freight-related air pollution.

Supporting Circular Economy

Intermodal’s use of standardized containers facilitates the transport of waste and recycled materials, supporting circular economy initiatives. Companies can more easily integrate recycling and waste reduction into their supply chains using intermodal.

Intermodal shipping’s sustainability advantages align with corporate goals such as reducing carbon footprint, improving energy efficiency, and supporting sustainable development. By incorporating intermodal into their supply chain strategies, companies can make significant strides towards their sustainability objectives.
