Sustainability plans for delivery fleets almost always start in the same place: swap the vans for electric ones. It’s an easy line item to point to, and it looks good in a report. But it skips over where most of the wasted fuel and emissions actually come from — not the engine under the hood, but the miles that never needed to be driven in the first place.
Before spending on new vehicles, it’s worth asking a less flattering question: how much of what your fleet drives today is actually necessary?
Repeated Attempts Are an Emissions Problem Wearing a Customer Service Costume
A failed delivery doesn’t just cost a rescheduling headache — it means the same distance gets driven twice, with double the fuel and double the emissions for a single parcel. Most of these repeat trips trace back to something avoidable: wrong access notes, nobody confirming they’d be home, a driver circling the same block looking for parking. Lastmily’s saved recipient profiles capture parking spots, entrance codes, and access notes the first time a driver figures them out, then reuse that knowledge automatically on every future visit to the same address — cutting failed attempts before they turn into a second trip.
Dense Neighborhoods Don’t Need a Van Idling on Every Corner
In city centers, a lot of fuel gets burned circling the block looking for parking, then re-entering traffic for a stop two buildings away. Lastmily’s Walking Group groups nearby deliveries under a single parking spot, so a driver parks once and completes a cluster of drop-offs on foot instead of driving — and re-idling — between each one.
A Half-Empty Van Is Still Burning a Full Tank
Sending out more vehicles than the day’s volume actually requires is one of the quieter ways fleets waste fuel — each additional van on the road adds emissions regardless of how full it is. Matching order volume to the right mix of in-house drivers and third-party couriers, instead of defaulting to a fixed number of vehicles, keeps utilization high and avoids sending out capacity nobody needed that day.
If You’re Not Measuring It Per Stop, You’re Not Really Measuring It
Fuel use and emissions reported at the fleet level hide where the actual waste is happening. Breaking it down per completed stop — instead of per vehicle or per day — shows which zones, time windows, or delivery patterns are quietly driving up consumption, so the fix can target the actual cause instead of the whole fleet.
Efficiency First, Then Electrify
None of this argues against electric fleets — it argues against treating them as the starting move. A route full of wasted miles and failed attempts is expensive to run whether the van burns diesel or electricity. Fixing the routing and first-attempt problem first means whatever fleet a business eventually electrifies is already running as lean as it can.
Cut the Waste Before You Change the Fleet
Sustainable last mile delivery isn’t a separate initiative bolted onto operations — it’s what happens when route optimization and dynamic route planning are already doing their job well. Lastmily partners running on these efficiencies have cut CO2 emissions by as much as 23%, and in some cases reduced operational costs and emissions together by up to 30%, without replacing a single vehicle.
