Reducing Carbon Emissions with Intermodal Freight: What Shippers Need to Know
In today’s business landscape, sustainability is a global imperative. Companies across all industries are facing increasing pressure from consumers, investors, and regulators to operate more responsibly. This push has given rise to a new standard for corporate accountability: Environmental, Social, and Governance (ESG) criteria. Businesses are now setting ambitious goals, from reducing waste to achieving “net-zero” carbon emissions, and are actively seeking tangible ways to make their operations greener.
For the vast majority of companies that produce or sell physical goods, one area stands out as the single greatest source of their carbon footprint: the supply chain. The journey a product takes from the factory to the final customer is long and complex, involving multiple modes of transport and generating significant emissions along the way. This makes logistics the most critical area for any business looking to make a meaningful impact on its environmental goals.
Mapping the Carbon Journey of Your Goods
Virtually every industry relies on complex, long-distance freight shipping to bring its products to market. From retail and e-commerce giants moving consumer goods to automotive and manufacturing companies transporting heavy parts and materials, a dependable supply chain is essential. But this dependability often comes at a high environmental cost.
To understand how to reduce emissions, we first have to identify where they come from. A typical supply chain journey has several emissions hotspots:
- Global Shipping: For imported goods, the journey begins on massive ocean liners or, for time-sensitive products, air freight. Both are significant sources of greenhouse gas emissions.
- Port and Terminal Operations: Once goods arrive, a flurry of activity takes place. Cranes, yard hostlers, and the fleet of drayage trucks that shuttle containers around the port all consume energy and produce emissions.
- The Long Haul: This is often the most carbon-intensive part of the journey. Traditionally, goods are loaded onto trucks for long-haul trips that can span hundreds or even thousands of miles, burning a tremendous amount of fossil fuel.
- Warehousing and Final Mile: The final stages, including storage in distribution centers and the last leg of delivery to a store or customer, add to the cumulative carbon footprint.
The journey is a long one—and often comes with multiple legs and energy sources to make possible the delivery of goods from source to final destination.
Smart Shipping: How Intermodal Freight Slashes Emissions
When looking at the entire supply chain, the long-haul portion presents the single most significant opportunity for decarbonization. The most effective and widely adopted strategy for achieving this is through intermodal freight.
Intermodal transportation involves using two or more modes of transport to move a container from its origin to its destination. By shifting the long-haul portion of the journey from the highway to the railway, businesses can achieve a dramatic reduction in their carbon footprint.
- The Power of Rail: The science is clear: trains are vastly more fuel-efficient than trucks for moving freight over long distances. According to industry data, a single train can move one ton of freight nearly 500 miles on just one gallon of fuel. This efficiency means that shipping by rail can reduce greenhouse gas emissions by up to 75% compared to over-the-road trucking.
- Reducing Highway Congestion: Every container moved by train is one less truck on the highway. This not only reduces direct emissions but also helps alleviate traffic congestion, which itself is a source of wasted fuel and unnecessary pollution.
- Optimized Drayage: Intermodal doesn’t eliminate the need for trucks; it simply uses them more intelligently. Efficient drayage services are used for the short first- and last-mile trips to and from the rail terminals, ensuring that trucking is reserved for the part of the journey where it is most effective.
By combining the strengths of both rail and truck, intermodal freight offers a powerful solution for creating a more sustainable supply chain. This strategy is often complemented by other green logistics tactics, such as intelligent load consolidation to ensure every container is shipped at maximum capacity, further improving efficiency.
A Shipper’s Checklist for a Greener Supply Chain
For any business leader or logistics manager looking to align their operations with corporate ESG goals, evaluating your current shipping strategy is the first step. Here is a simple checklist to help you identify your biggest opportunities for improvement:
- Are we using rail for hauls over 500 miles? If your products are traveling long distances exclusively by truck, you are missing out on the most significant opportunity to reduce both your carbon emissions and your shipping costs.
- Is our drayage network efficient? Are your first- and last-mile trucking routes optimized to be as short as possible? Minimizing truck miles is key to maximizing the benefits of intermodal.
- Do we have clear visibility into our carbon footprint? You can’t improve what you don’t measure. A modern logistics partner should be able to provide you with data on the emissions generated by your shipments.
- Are we maximizing container capacity? Are your containers being shipped full? Improving load consolidation is a simple way to make every shipment more efficient.
- Does our logistics partner share our commitment to sustainability? Is your current provider proactively helping you find and implement greener solutions, or are they simply maintaining the status quo?
Creating a sustainable supply chain is a complex challenge, but it is one that modern businesses must meet head-on. It requires deep industry knowledge, a vast and flexible network, and cutting-edge technology to manage all the moving parts.
