Routing decisions that balance transit time, price and emissions across the network — and treat a tonne of CO₂e as the line item it's quietly becoming.
Routing has always been a two-axis trade: price against time, pick the cheapest option that still hits the date. Emissions came free, so it stayed invisible — a by-product nobody costed. That era is closing. Carbon border adjustments, Scope 3 disclosure, retailer mandates and net-zero commitments are turning a tonne of CO₂e into a line with a price attached and a paper trail behind it. And the reflex answer to any deadline pressure — air-freight it to be safe — is quietly the worst seat in the house: it is the most expensive route and the most carbon-intensive, often by an order of magnitude, and most of what flies never needed to. It's a planning gap paid for twice. Optimise on dollars alone and you leave a growing liability sitting off the books.
Add emissions as a third, priced axis and the decision changes shape. The cheapest-dollar route and the lowest-carbon route usually point the same way — ocean is both — so the real tension is time: every step toward speed costs you in both currencies at once. The skill is spending the time budget deliberately rather than by default — moving the bulk by sea or rail where the calendar allows, consolidating loads, and holding air in reserve for what is genuinely urgent. The quiet lever is lead time: buy a few days earlier and you drop off the air-freight cliff, cutting dollars and carbon together in a single move. Green Lane surfaces that frontier on every consignment, so the trade-off between speed, spend and emissions becomes a choice you make with the numbers in front of you — not a default you inherit.
Every routing option plotted on dollar cost and carbon — the two costs that move together. Transit time is the third axis, labelled on each point. The pattern is the lesson: paying for speed bills you twice, in cash and in emissions.
One shipment, three ways across the network. With a two-week delivery window, ocean is off the table — so the Green Lane choice is the lowest-carbon route that still lands in time, not the fastest one available.
Emissions figures are modelled estimates (mode, distance, load factor) and vary by carrier and lane; treat them as decision-grade, not audit-grade. Green Lane optimises within your stated delivery window — it never trades away a date you need. Prices, transit times and CO₂e shown are illustrative.
It sits inside the Caboodle Supply Chain product set alongside TariffPath and Predictive Rate Lock. Each is a lever on landed cost and lead time — designed to compound, not replace each other.
