As e-commerce continues to expand across Europe, the environmental impact of parcel delivery is becoming increasingly important. More online orders usually mean more delivery vehicles, more stops, more congestion, and higher emissions—especially during the last mile.
Poland, however, has developed one of the most efficient e-commerce delivery models in the European Union.
There is no official EU ranking that identifies one country as the greenest market for e-commerce delivery. Nevertheless, Poland has the strongest claim thanks to its dense parcel-locker network, widespread consumer adoption and highly consolidated last-mile delivery system.
The last mile is often one of the least efficient stages of e-commerce logistics.
Large trucks can transport thousands of parcels between fulfillment centers and regional depots. Once those parcels enter the final delivery stage, they must be distributed across hundreds of individual addresses.
Traditional home delivery can involve:
Parcel lockers help address this problem by allowing carriers to deliver dozens of orders to a single location rather than visiting each customer individually.
This is where Poland has gained a significant advantage.
Parcel lockers are not a niche delivery option in Poland. They are a central part of the country’s e-commerce infrastructure.
Recent industry estimates indicate that Poland has more than one parcel locker per 1,000 inhabitants, the highest density in Europe. The total national network is estimated at approximately 45,000 to 47,000 automated parcel machines.
InPost is the country’s dominant operator. At the end of the first quarter of 2025, the company operated 25,949 automated parcel machines in Poland, representing annual growth of around 15%.
Competition is also increasing. Allegro, DHL, DPD, Orlen and other operators continue to expand their own locker and pickup-point networks.
This means Polish consumers can frequently find a locker close to their home, workplace, supermarket or daily commuting route.
The environmental benefit of parcel lockers is based on consolidation.
A courier delivering 50 parcels to individual homes may need to make dozens of separate stops. The same 50 parcels can potentially be delivered to one or two automated machines.
This can reduce:
InPost has reported that deliveries to its automated parcel machines generate significantly lower emissions per parcel than home delivery. The company has also estimated that its locker network avoided more than 180,000 tonnes of carbon dioxide emissions in Poland in 2020.
These numbers are based on company calculations rather than a standardized EU methodology, so they should be interpreted carefully. However, the operational principle is clear: delivering many parcels to one location is usually more efficient than delivering them individually.
Parcel lockers are not automatically sustainable. If customers drive several kilometers solely to collect an order, part of the emissions advantage can disappear. Locker location and consumer behavior are therefore essential.
Poland performs particularly well because parcel collection is often integrated into everyday journeys.
Industry research suggests that approximately 62% of Polish users collect parcels while already traveling for another purpose. In urban areas, the average distance to a locker has been estimated at around 350 meters.
This makes it more likely that customers will collect parcels while walking, commuting, shopping or traveling home from work.
The density of Poland’s network is therefore one of its greatest strengths. The closer lockers are to consumers, the less likely they are to require a separate car journey.
Failed home deliveries create additional emissions and costs. When a customer is unavailable, the carrier may need to attempt delivery again, redirect the parcel or return it to a depot.
Parcel lockers largely eliminate this issue. Once the parcel is deposited, the delivery is complete, and the customer can collect it at a convenient time.
This improves first-attempt delivery rates and allows carriers to organize more predictable and efficient routes.
One reason the Polish model has grown so quickly is that parcel lockers are not only more efficient. They are also convenient.
They offer consumers:
Poland shows that sustainable delivery models are more likely to succeed when the environmentally preferable option is also the easiest option.
Consumers may choose lockers primarily for convenience, but the result is still a more consolidated and potentially lower-emission delivery network.
Poland is one of Europe’s fastest-developing e-commerce markets.
Polish logistics forecasts suggested that parcel operators could handle approximately 1.34 billion shipments in 2025, compared with around 1.21 billion in 2024.
Managing this growth entirely through home delivery would create additional pressure on roads, fleets and urban areas.
Poland’s out-of-home delivery infrastructure allows the market to absorb rising parcel volumes without requiring an equivalent increase in individual residential delivery stops.
It does not make the entire e-commerce supply chain carbon-free. Fulfillment centers, long-distance transport, packaging, returns and electricity consumption still generate emissions.
However, it provides a scalable way to make the last mile more efficient.
Poland has not been officially recognized as the EU’s greenest country for e-commerce delivery.
There is currently no European index that compares all member states using the same indicators, such as:
Countries such as Finland, Sweden, Denmark, Germany and the Netherlands also have strong sustainability credentials.
Nordic markets are advanced in electric delivery fleets and fossil-free fuels, while Germany and the Netherlands have invested heavily in electric vans, cargo bikes and zero-emission urban logistics.
Poland’s strength is different. It has created Europe’s most developed consolidated parcel-delivery ecosystem.
For this reason, it is more accurate to describe Poland as the EU leader in eco-efficient e-commerce delivery infrastructure rather than as the officially greenest delivery country.
The Polish model offers several lessons for European retailers and logistics providers.
Parcel lockers should be offered prominently during checkout instead of appearing as a secondary option.
Lockers deliver the greatest environmental benefit when they are close to homes, workplaces, shops and public transport.
Retailers can promote lockers through lower prices, loyalty rewards or clear sustainability information.
Using the same network for deliveries and returns can reduce home collections and simplify reverse logistics.
The most sustainable model combines parcel consolidation with electric vans, cargo bikes, renewable electricity and route optimization.
Poland’s position as a leader in eco-friendly e-commerce delivery is based on structural efficiency rather than a single environmental initiative.
Its dense parcel-locker network reduces the number of stops required to deliver growing volumes of online orders. Widespread consumer adoption also means that lockers are integrated into daily life rather than treated as an occasional alternative.
The system is not completely emission-free, and its environmental performance still depends on vehicle type, locker location and customer behavior.
Nevertheless, Poland offers one of Europe’s clearest examples of how convenience, efficiency and sustainability can support one another.
As e-commerce parcel volumes continue to rise, Poland’s delivery model could become an increasingly important blueprint for building a greener and more scalable European last mile.
