Carbon-Aware Routing Engine

The engine dynamically applies GLEC Framework and ISO 14083 compliant emission factors. It does not use static averages; instead, it selects the precise Well-to-Wheel (WTW) conversion factor based on real-time variables including fuel type, Euro class engine standard, vehicle gross weight, and current payload utilization. This ensures the carbon calculation reflects the specific asset executing the move, not just a generic mode average.

Standard GPS routing minimizes time; carbon-aware routing minimizes energy expenditure. The engine ingests high-resolution digital elevation models to penalize steep gradients that spike fuel consumption. It overlays real-time traffic telemetry to avoid stop-and-go congestion patterns, which cause inefficient engine operation. The solver distinguishes between a highway jam and a steady urban flow, calculating the precise grams of CO2e per kilometer for each road segment.

The engine does not just optimize a single mode; it evaluates the carbon abatement curve for the entire corridor. It algorithmically identifies breakpoints where shifting from air to road, or road to rail, becomes viable. The solver calculates the Carbon-Adjusted Total Cost of Ownership (TCO) , factoring in an internal carbon price to justify the shift. It ensures the modal transfer point is logistically feasible and does not violate the delivery window.

The routing decision is inseparable from vehicle utilization. The engine scores potential routes by their Emission Intensity Index (gCO2e/ton-km), penalizing empty backhauls. It interfaces with a Load Consolidation Algorithm to group Less-than-Truckload (LTL) shipments into Full-Truckload (FTL) movements. By maximizing the payload-to-vehicle-weight ratio, the engine directly reduces the per-unit emission allocation for every item on the truck.

Beyond routing, the engine quantifies the impact of operational decarbonization investments. If a route mandates the use of Hydrotreated Vegetable Oil (HVO) biofuel or an electric vehicle on a specific leg, the engine calculates the precise emission reduction. It applies a Mass Balance Chain of Custody model to verify the sustainable fuel claim and generates a digital record for Carbon Insetting Logic, allowing the shipper to neutralize the footprint of that specific shipment within their own value chain.

Every emission calculation is a defensible data point, not a black-box estimate. The engine records the Carbon Data Provenance for each routing decision, cryptographically linking the output to the specific emission factor version, timestamped telemetry data, and vehicle specification used. This creates an immutable audit trail for Scope 3 Emission Modeling and Carbon Disclosure Project (CDP) reporting, satisfying external assurance requirements without manual data collection.

The foundational life-cycle analysis method that a routing engine uses to account for total energy consumption. It splits emissions into two stages: well-to-tank (fuel production, refining, and distribution) and tank-to-wheel (combustion during vehicle operation). A routing engine relying solely on tank-to-wheel data would ignore the significant upstream emissions from electricity generation for EVs or hydrogen production for fuel cells, leading to suboptimal modal choices.

A critical sub-component that automatically selects the most appropriate CO2e conversion factor from a managed database. For a given transport leg, it must match the correct factor based on:

• Mode: Air, ocean, road, rail, barge
• Fuel type: Diesel, LNG, SAF, electricity
• Vehicle specification: Payload capacity, Euro class
• Load factor: Actual vs. maximum payload Without precise factor matching, the routing engine's output is an estimate, not a calculation.

The algorithmic process that a routing engine triggers when it identifies a viable, lower-emission alternative. It analyzes freight flows to determine if cargo can be transferred from a high-emission mode—like air freight or long-haul trucking—to a lower-emission one, such as rail or inland barge. The engine must balance the carbon reduction against cost and transit time constraints to propose a shift that is both environmentally and commercially viable.

An algorithm that identifies and quantifies emission reduction investments made within a company's own supply chain to neutralize a specific shipment's footprint. Unlike purchasing external carbon offsets, insetting funds projects like switching a carrier to renewable diesel or installing electric vehicle charging infrastructure at a supplier's facility. The routing engine can prioritize carriers offering insetting programs, directly linking operational decisions to verified decarbonization.

A virtual replica of the physical supply chain network that simulates the carbon impact of operational decisions in real-time. A routing engine can be integrated with a digital twin to run what-if scenarios—such as shifting a distribution center's location or changing a fleet's fuel mix—without disrupting live operations. This allows sustainability officers to stress-test decarbonization strategies before committing capital.
