About E-Commerce Return and Last-Mile Carbon Calculator
Free last-mile estimator: parcel weight, delivery vehicle and return-trip toggle into kg CO2e per order. For DTC stores and conscious shoppers. No signup.
Why returns double the damage
A returned parcel travels the last mile twice plus reverse-logistics handling. Tick the return box and watch the footprint roughly double: the cheapest sustainability win is fewer returns, not greener vans.
Vans versus bikes
A diesel van parcel runs near 0.8 kg CO2e against about 0.25 for an electric van and 0.02 for a cargo bike. Weight adds a smaller surcharge on top of the per-parcel base.

Frequently Asked Questions about E-Commerce Return and Last-Mile Carbon Calculator
How much CO2 is one delivery?
Roughly 0.8 kg CO2e by diesel van, 0.25 kg by electric van, and 0.02 kg by cargo bike per parcel, plus a small weight surcharge.
Why do returns matter so much?
A return repeats the trip and adds warehouse handling, roughly doubling the order footprint. Cutting return rates is the fastest lever.
Does parcel weight matter?
Somewhat: about 0.05 kg CO2e per extra kilogram. Vehicle choice matters far more than shaving grams.
Are these store-ready numbers?
They are estimates for planning and customer communications, not lifecycle-assessed figures.
