This article walks you through the CO₂ calculator under the Tools tab. Use this to estimate the carbon emissions for a specific shipment — for SmartWay reporting, customer sustainability requests, or internal environmental tracking.
Why this matters: polt.ai maintains SmartWay certification, which requires accurate mileage and emissions tracking. The CO₂ calculator gives you a quick estimate for individual loads. Note that mileage entered when creating a shipment is what feeds SmartWay reporting directly — this tool is for estimation and reference, not the source of record.
From the top nav, click Tools and select CO₂ calculator. The calculator opens as a modal over the Fuel Prices page.
Fill in the four input fields:
Field | What to enter |
Truck miles | Total miles for the shipment |
Weight | Freight weight in pounds (lb) |
Equipment type | The trailer type (e.g., Flatbed Team, Dry Van, Reefer) |
VIN | The truck's VIN number (optional) |
Click Calculate.
The calculator returns two outputs:
Total CO₂ (tCO₂e) — the estimated total carbon dioxide equivalent emissions for the shipment, in metric tons
CO₂ intensity (kg/mi) — the emissions per mile, in kilograms
It also displays an efficiency rating based on the result — for example, CO₂ emissions: Efficient — giving you a quick read on where this load falls relative to typical benchmarks.
