LTL is one of the most complex daily transport operations in American commerce — a hub-and-spoke system that is both community-based and network-connected. It resembles an industrial ballet: more than 600,000 shipments are matched with tens of thousands of drivers and equipment assets, moving through a network of nearly 3,300 terminals, choreographed every single day. At its core, LTL is a highly engineered solution, where data serves as the foundation for the remarkable efficiency with which the industry moves the nation’s freight.
That same data now sits at the center of Scope 3 emissions reporting. Sustainability has a long track record in LTL. Early efforts to track transport-related emissions relied on industry averages, and that was the right place to start.
But over time, it’s created an overreliance on aggregate data and network averages, an institutionalized abstraction that obscures what’s happening across individual shipments. And in a market rewriting what carriers must prove on fuel, data and emissions, that imprecision is no longer affordable.
Shipment-level intelligence ends this era of approximation. It finally gives carriers the precision the work has always required and turns today’s pressures into a competitive advantage.
Shipper requirements and Scope 3 are converging on LTL
Shipper requirements relating to emissions tracking are becoming more specific, and new regulatory requirements are due to come online next year.
What used to feel optional is now a threshold requirement. Third-party sustainability surveys, customer disclosure requests and emissions reporting expectations are no longer side conversations — they’re showing up in quarterly business reviews and becoming part of how shippers evaluate carrier relationships. On the issues where trucking intersects with broader societal interests — safety, security and sustainability chiefly among them — shippers are asking for more data, and they’re asking for it to be verifiable.
Regulation is accelerating this shift. California’s SB 253 requires large companies doing business in the state to report Scope 1 and 2 emissions, with Scope 3 reporting requirements beginning in 2027. Even if a carrier is based outside California, if it moves freight for a covered shipper whose supply chain touches the state, its transportation activity becomes part of that shipper’s Scope 3 reporting obligation.
As other states consider similar requirements, carriers serving national shippers should expect those requests to become more frequent and more detailed. Broad averages don’t hold up well in that environment, and carriers that can walk a shipper through their allocation logic — clearly and consistently — earn trust faster. In tight bid cycles, that matters.
Using the allocation math you already have
The LTL industry has run sophisticated activity-based costing for years. Allocating labor, fuel, mileage and trailer time to individual shipments across each leg of their journey is the most reliable way to know the actual cost of moving a thousand-pound shipment through a hub-and-spoke network.
Shipment-level emissions reporting leverages that same logic and asks carriers to do what cost-to-serve already requires: trace shared network activity back to individual shipments. Separating city pickup and delivery, cross-dock handling and linehaul movement is how each shipment carries its share.
Take a 1,000-pound shipment from Minneapolis to Kansas City, for example. It gets picked up on a city truck, cross-docked at the Minneapolis terminal, loaded onto a linehaul trailer alongside 15 other shipments from different customers, transferred to Kansas City via linehaul, then cross-docked and delivered on another city route. In total, that’s three trailers, three tractors and two docks, each requiring a different allocation based on load optimization. An emissions estimate loaded with too many industry default averages falls short of the accuracy required for Scope 3 reporting.
Granular freight data lets carriers separate what’s happening on the city side from what’s happening on linehaul, then measure each appropriately. It’s the difference between treating a circuitous pickup-and-delivery run as a single average and understanding which shipments are driving time, fuel and dock activity. It makes it easier to build better outbound plans, and the shipment receives an accurate emissions calculation.
Efficiency and emissions aren’t two problems. They’re one ledger.
Delays that show up as cost for carriers also show up as emissions for regulators. This is what eventually helped shape the creation of SmartWay. It recognized something that carriers already understood — fuel waste, idle time and inefficient movement show up in both operating costs and emissions.
Shipment-level intelligence enables carriers to act on that principle with greater precision. Better load planning, powered by AI technology tools, can help carriers avoid unnecessary moves and preserve road capacity for freight that needs it. The same efficiencies are gained through routing for city pickups and deliveries.
When California diesel recently spiked past $7 per gallon, carriers that had invested in backward-compatible alternatives such as bio- and renewable diesel made their operations more resilient. What began as a sustainability effort ended up providing business continuity when it was needed most.
Shipment-level intelligence makes those connections visible sooner, showing carriers where cost exposure, fuel use, capacity waste and emissions are driven by the same operational conditions.
Where precision goes next
Shipment-level data is the new operating baseline. But the work of getting more precise doesn’t stop there. Equipment-level intelligence is our next step.
Knowing what a specific tractor burns on a specific fuel type on a specific lane changes how carriers operate their fleet and how they buy fuel. And with the industry moving through a transition across biodiesel, renewable diesel, renewable natural gas, hydrogen and electric, carriers who can measure performance across these fuels under real operating conditions on their own networks will make better decisions than those relying on specs and averages.
Terminal-level visibility is another logical next step. Current calculations capture city pickup and delivery and linehaul miles, but every shipment also touches a forklift, a dock and the energy that runs them. Those terminal touches may represent a smaller share of the total footprint than linehaul, but are still part of the shipment’s journey, and the next level of precision is learning how to account for them consistently.
Years ago, shippers were telling carriers with nearly identical operations that their emissions reports looked nothing alike. It was like the Wild West, with no governing or guiding factor to align carriers on a uniform emissions reporting standard. But the industry eventually came together, established a uniform standard, and the reports improved. That’s how we’ll move forward this time, too.
The carriers best positioned today are those that began doing this kind of work before it was required. As the next areas for optimization come into focus, the advantage will go to carriers that keep refining the data, strengthening the methodology, and using both to make better operating decisions.
