Sustainable fulfillment means designing warehousing, packaging and shipping so that less material, less transport and less waste are generated per order. The biggest levers are suitable packaging sizes, recyclable materials, consolidated shipments, a well-considered choice of routes and carriers and fewer returns. Many of these measures reduce costs at the same time.
Why sustainable fulfillment matters for online retailers
In online retail, every order is packed and transported individually. With many shipments, small differences quickly add up: a carton that is too big, a filling that would not be necessary, a shipment that travels twice because it comes back. Sustainability in fulfillment therefore arises less from a single big measure than from many sound decisions in everyday operations.
On top of that come legal requirements. In Germany, the Packaging Act (Verpackungsgesetz) obliges retailers that ship packaged goods to private end consumers to register in the LUCID packaging register and to participate in a dual system for sales and shipping packaging. At EU level, the new Packaging and Packaging Waste Regulation (PPWR) gradually introduces further obligations, including on recyclability and empty space in shipping packaging. The deadlines are staggered. Check the current status with the Zentrale Stelle Verpackungsregister (Central Agency Packaging Register) or your legal adviser.
Last but not least, customers and business partners pay attention to packaging and shipping. An oversized carton with lots of filling material is noticed immediately when unpacking.
Lever 1: Packaging in the right size
Packaging is the most visible lever and often the simplest. A carton that fits the goods exactly needs less material, less filling and less space in the transport vehicle. At the same time, it protects the goods better because they do not slide around inside.
- Review your carton range: compare the dimensions of your best-selling items with the cartons you actually use. Often one or two intermediate sizes are missing.
- Use mailer bags: for textiles and robust items, a mailer bag is often enough instead of a carton.
- Define packaging per item: store in the warehouse system which carton belongs to which item. Then not every packer decides anew.
- Ship-ready manufacturer packaging: some products can be shipped in their sturdy original packaging, with just a shipping label.
Use filling material in a targeted way
Filling material should fix the goods in place, not compensate for empty space. If a lot of filling is regularly needed, the carton is usually too big. Define which items need padding at all, and train the packing team accordingly. Fragile goods need protection at corners and edges, robust goods often none at all.
Suitable packaging has another effect: many parcel services also calculate prices by size or volumetric weight. A smaller carton can therefore directly save shipping costs.
Lever 2: Recyclable and single-material packaging
The second lever is the material. The goal is packaging that the recipient can easily separate and dispose of.
- Paper and cardboard instead of plastic: paper padding, corrugated inserts or paper tape instead of bubble wrap and plastic tape, where the protection is sufficient.
- Single-material packaging: the fewer materials are combined, the easier the recycling. A carton with paper tape and paper padding can go entirely into the paper recycling.
- Recycled content: cartons with a high share of recycled paper are sufficiently stable for many goods.
- Reuse: in B2B shipping and for deliveries to the warehouse, reusable containers and exchangeable pallets can be used. In consumer shipping, there are reusable packaging solutions that the customer sends back.
It is important that the goods still arrive safely. A damaged shipment creates a replacement delivery and a return and cancels out any material advantage.
Lever 3: Bundle and consolidate shipments
Every shipment that does not have to travel separately saves transport. Consolidation works on several levels:
- Combine orders: if a customer orders several items, they should go in one parcel if all are available. Split shipments only when they are really necessary.
- Deliver replenishment in bulk: inbound deliveries to the fulfillment warehouse should arrive as full pallets or as a consolidated delivery, not in many individual parcels.
- Choose the right mode of transport: several pallets to the same recipient often travel more efficiently as a part load or full truckload than individually as groupage. The differences are explained in our blog.
- Warehouse close to customers: a warehouse location that suits your recipients shortens the route of every single shipment.
Consolidation is easier when warehousing, shipping and transport are in one hand. If you store goods with a provider and also organise pallet and groupage transports from there, you can better coordinate deliveries and pickups. FulFra offers e-commerce fulfillment from its own warehouse in Lehrte near Hanover and organises freight and transport from parcels to full truckloads.
Lever 4: Choice of routes and carriers
Not every shipment has to arrive as fast as possible. If there is time, transports can be better consolidated and vehicles better utilised. So ask for every type of shipment: which transit time does the recipient really need?
- Choose transit times consciously: express services for urgent cases, standard transit times for everything else.
- Pay attention to utilisation: a well-loaded pallet is more efficient than a half-empty one. How to pack and secure pallets correctly is explained in our blog.
- Compare carriers: parcel services and freight forwarders use different vehicles and delivery concepts. Ask which emissions data they can provide.
- Avoid delivery attempts: correct addresses, parcel lockers and pickup points reduce the number of failed delivery attempts.
FulFra works with a network of more than 50 carriers. In the price calculator, you choose between the service levels Eco, Super-Eco and Express for parcels, groupage, pallets and full truckloads and see the price instantly.
Lever 5: Avoid returns
A return at least doubles the transport route of an item. On top of that come new packaging, inspection and, in the worst case, disposal. Avoiding returns is therefore one of the most effective levers for sustainable fulfillment.
- Accurate product descriptions, measurements and size charts.
- Realistic product photos.
- Error-free picking, so that the right item arrives.
- Protective packaging that prevents transport damage.
- Inspect returns and resell as much of the goods as possible instead of disposing of them.
A related point is inventory planning. Goods that do not sell occupy storage space and, in the worst case, are written off and disposed of. Realistic order quantities and a regular look at slow-moving stock prevent this.

Measuring sustainability in fulfillment
Without measurement, sustainability goals remain vague. Choose a few metrics that you can collect regularly:
- Packaging material per order: weight of carton, filling and tape per shipment, broken down by material.
- Fill rate of parcels: how much empty space remains in the carton? Random samples are enough to start with.
- Shipments per order: how often is an order split into several parcels?
- Return rate: in total and per item, with return reasons.
- Transport emissions: there are recognised calculation methods such as the ISO 14083 standard. Ask your carriers which values they provide.
Set a baseline for each metric and check how measures take effect. When you communicate about sustainability, stay specific and back up statements with your own data. Only use general promises such as "climate neutral" with a solid basis.
Frequently asked questions
What is the most important lever for sustainable fulfillment?
For most online retailers, it is packaging size and returns. A suitable carton saves material and transport space, and every avoided return saves a complete return transport including processing.
Do I have to register in the packaging register as an online retailer?
Anyone in Germany who ships packaged goods to private end consumers generally has to register in the LUCID packaging register and participate in a dual system. This also applies to shipping cartons and filling material. Check your case with the Zentrale Stelle Verpackungsregister.
Is slower shipping more sustainable?
Not automatically. A longer transit time can, however, help to consolidate shipments and utilise vehicles better. Only choose express where the recipient really needs the goods quickly.
How do I measure the success of my measures?
With a few regularly collected metrics: packaging material per order, fill rate, shipments per order, return rate and, where available, transport emissions. Compare the values with a fixed baseline.
