Low-carbon supply chains in Poland: warehouse design, route consolidation and emission reporting
Electrifying delivery vehicles addresses scope 1 emissions from direct fuel combustion. The broader freight carbon picture — covering warehouses, cold chains, inbound transport and supplier logistics — requires a different set of interventions.

The scope 3 problem in freight
The Greenhouse Gas Protocol categorises emissions into three scopes. Scope 1 covers direct emissions from owned assets — fuel burned in company vehicles. Scope 2 covers purchased energy — electricity consumed at depots and warehouses. Scope 3 covers all other indirect emissions, including those generated by contracted carriers, suppliers' inbound transport and customers' reverse logistics.
For a manufacturer or retailer using third-party logistics, the majority of freight-related emissions sit in scope 3. Measuring and reducing them requires data from logistics partners that is not always available in usable form. The EU's Corporate Sustainability Reporting Directive (CSRD), which entered phased application from 2024, is driving more consistent disclosure requirements, including for value chain emissions.
Warehouse energy consumption in Poland
Poland has a large and growing modern logistics warehouse stock, concentrated in clusters around Warsaw, Łódź, Wrocław, the Upper Silesia conurbation and near the Poznań agglomeration. Many facilities built since 2015 have been developed under BREEAM or LEED certification schemes, which impose energy performance standards on building fabric and systems.
Key energy consumers in a logistics warehouse include:
- Lighting — large-footprint sheds require significant illumination; LED retrofits and daylight harvesting controls reduce this load.
- Heating — uninsulated older warehouses are energy-intensive to heat in Polish winter conditions; modern facilities use better insulation standards.
- Refrigeration and cold store equipment — for food and pharmaceutical logistics, refrigeration accounts for a substantial share of site energy.
- Conveyor and sortation equipment — automated parcel handling generates significant electrical demand at high-throughput depots.
Rooftop photovoltaic installation has become standard in new logistics developments in Poland, driven by falling panel costs and power purchase agreement structures that allow operators to offset grid electricity with on-site generation.
Route consolidation and load factor
A loaded vehicle moving through a supply chain has a lower emission intensity per unit of freight than a partly empty one. Improving load factor — filling available vehicle capacity before departing — reduces the number of vehicle movements required for a given freight volume.
This is straightforward in principle but operationally complex. Customer delivery windows, product handling requirements, geographic dispersion of shipment origins and destinations, and the time sensitivity of different freight categories all constrain how consolidation can be achieved in practice.
Urban freight consolidation centres — facilities where shipments from multiple carriers are combined for delivery by a shared fleet on the final kilometre — have been piloted in a number of European cities. In Poland, formal shared city logistics schemes remain limited, but some municipality-carrier discussions on the topic have been reported in the context of city logistics planning in Warsaw and Kraków.
Carbon calculation methodologies
Freight emissions are typically calculated using activity-based methods (distance multiplied by emission factor for vehicle type and fuel) or spend-based methods (financial spend multiplied by an emission intensity factor). The GLEC Framework, published by the Global Logistics Emissions Council and adopted by the Smart Freight Centre, provides a common methodology for freight transport emission calculations.
Polish logistics operators that are subsidiaries of international groups — including DHL, DPD (Geopost), XPO, DB Schenker and GLS — typically report using group-level methodologies aligned with recognised standards. Smaller domestic carriers may lack the reporting infrastructure to provide granular emission data to customers, which complicates scope 3 calculation for shippers using mixed carrier bases.
Green certification in logistics real estate
BREEAM (Building Research Establishment Environmental Assessment Method) and LEED (Leadership in Energy and Environmental Design) are the two principal green building certification schemes applied to logistics facilities in Poland. BREEAM is more commonly specified in Polish logistics development, partly reflecting the prevalence of UK-linked investment structures in the sector.
Certification covers site ecology, water efficiency, energy performance, materials specification and transport accessibility. A BREEAM "Excellent" or LEED "Gold" rated facility typically provides a lower baseline energy consumption than a facility built to minimum regulatory standards, but certification does not guarantee a specific absolute energy figure.
