Climate footprint in logistics – an underestimated challenge

In times of climate change, the carbon footprint of companies is increasingly coming into focus. While many businesses are already addressing energy consumption and transport routes, one decisive factor often remains unnoticed: the load carriers used.

Pallets, especially wooden pallets and Euro pallets, are the backbone of modern logistics. But how do they perform in terms of carbon footprint? The Wintergroup, a leading provider of sustainable pallet concepts, provides convincing answers.

This article sheds light on the CO₂ footprint of various pallet types and shows why wooden pallets are ahead in terms of climate protection – essential information for everyone who wants to make their supply chain more climate-friendly.

The carbon footprint of wooden pallets in comparison

When comparing the CO₂ footprint of different pallet types, significant differences emerge. A scientific analysis of the entire value chain reveals the environmental benefits of wooden pallets:

Plastic pallets vs. wooden pallets: Emissions in comparison

Plastic pallets are mainly produced from polyethylene (PE) or polypropylene (PP) – materials whose production is energy-intensive and based on fossil raw materials. The production of a single plastic pallet generates an average of 61 kg of CO₂ equivalents.

In contrast, the production of a wooden Euro pallet causes only 26 kg of CO₂. This corresponds to savings of over 57% – a remarkable difference that significantly impacts a company's carbon footprint when thousands of pallets are in circulation.

Metal pallets: The heavyweights in terms of CO₂ emissions

The comparison with aluminum pallets is even more severe. Their production causes 79 kg of CO₂ per pallet, which is more than three times the emissions of a comparable wooden pallet. Even though metal pallets have a longer service life, they can rarely compensate for this initial "climate burden."

The Wintergroup therefore consistently relies on wooden pallets and specifically on the European standard, the Euro pallet. In wholesale, this concept has proven itself for both ecological and economic reasons.

Natural CO₂ storage: How wooden pallets help the climate

Wooden pallets are not only more climate-friendly in production – they offer further decisive advantages:

The storage effect of wood

Trees absorb CO₂ from the atmosphere during their growth and store the carbon in the wood. This remains bound even after being processed into wood products such as Euro pallets or wood panels. A standard Euro pallet stores about 27 kg of CO₂ – and does so throughout its entire useful life.

Long-term binding through a circular economy

The long service life of the pallets is particularly valuable for the carbon footprint. The longer the wood remains in the economic cycle in the form of pallets, the longer the CO₂ remains bound. With the Wintergroup's repair service, the lifespan of a Euro pallet is extended from an average of 7 to up to 12 years – a significant period for CO₂ sequestration.

Wholesalers benefit from this system twice over: firstly, through reduced procurement costs for new pallets, and secondly, through the improved carbon footprint, which has a positive impact on the company's image.

The life cycle of a wooden pallet: CO₂ footprint from cradle to grave

To determine the actual CO₂ footprint of a pallet, its entire life cycle must be considered:

  1. Wood extraction and pallet production

The Wintergroup sources its wood exclusively from sustainably managed forests. This not only minimizes transport emissions but also ensures that new trees are planted for every one felled – an important aspect for a balanced carbon footprint.

State-of-the-art facilities are used in production, working in an energy- and resource-efficient manner. The wood waste generated during production is fully utilized – either as raw material for wood panels or for heat generation at the production site itself.

  1. Usage phase: Circulation in wholesale and logistics

During their usage phase, wooden pallets cause hardly any emissions. The standardized dimensions of the Euro pallet (1200 x 800 mm) enable optimal utilization of trucks and storage spaces, which further saves CO₂.

It becomes particularly environmentally friendly when pallets circulate in a pool system, as offered by Wintergroup. This reduces empty runs and avoids the production of new pallets – another advantage for the carbon footprint in wholesale.

  1. Repair and reuse

Damaged pallets are not disposed of but professionally repaired. During this process, only the defective parts are replaced. On average, these account for only 18% of the total material – the rest of the pallet and the CO₂ bound within it remain in the cycle.

The Wintergroup carries out over 500,000 repairs annually, saving around 15,000 tons of CO₂ compared to the new production of pallets.

  1. End-of-life: From waste wood to bioenergy

At the end of their life cycle, decommissioned wooden pallets and wood panels are processed into wood chips. This serves as a renewable raw material in biomass power plants and replaces fossil fuels.

Important to know: During combustion, only the CO₂ that was previously absorbed from the atmosphere by the tree is released – a climate-neutral process that significantly improves the carbon footprint.

Carbon footprint of the Euro pallet: Facts and figures

The climate benefits of wooden pallets can be expressed in concrete figures:

Emission savings over the entire life cycle

A scientific study by the Fraunhofer Institute analyzed the carbon footprint of various pallet types over their entire life cycle. The results are clear:

Pallet type Carbon footprint per life cycle
Wooden Euro pallet -5 kg CO₂ (negative!)
Plastic pallet +38 kg CO₂
Metal pallet +52 kg CO₂

The negative carbon footprint of the wooden pallet results from the CO₂ storage during its useful life, which exceeds the emissions from production and transport.

Practical example: CO₂ savings in figures

A medium-sized wholesaler that has 10,000 pallets in circulation annually can save about 430 tons of CO₂ per year by using wooden pallets instead of plastic pallets. This corresponds to:

  • The annual CO₂ emissions of about 50 average households
  • Over 2 million kilometers driven by car
  • The CO₂ sequestration capacity of approx. 34,400 trees

The role of wholesale in CO₂ reduction through optimized pallet usage

The wholesale sector plays a key role in the optimization of material flows. Through targeted measures, the carbon footprint of pallet usage can be further reduced:

Regional cycles and short transport routes

The closer the supplier, user, and repair service are to one another for pallets, the lower the transport emissions.

An example: For a regional food wholesaler, the average transport distance for pallets was reduced from 320 km to 75 km – a 76% CO₂ saving in the logistics process.

Certified sustainability: PEFC and others as a guarantee for climate-friendly wooden pallets

Not every wooden pallet is automatically climate-friendly. The origin of the wood used is decisive:

PEFC certification: Guarantee for sustainable forest management

The Wintergroup uses exclusively PEFC-certified wood for the production and repair of Euro pallets. This certification guarantees:

  • No overexploitation of forests (sustainable extraction volumes)
  • Continuous reforestation
  • Preservation of biodiversity
  • Avoidance of environmentally harmful chemicals
  • Fair working conditions in forestry

Every PEFC-certified Euro pallet therefore actively contributes to climate protection – an important criterion for environmentally conscious companies.

EPAL and UIC: Quality standards with a climate advantage

Standardizing pallets according to EPAL or UIC standards does not just have logistical advantages. Uniform dimensions and quality requirements also facilitate repair and reuse. This increases turnover rates and significantly extends the CO₂ storage duration.

The Wintergroup works exclusively according to these recognized standards, thereby creating the best conditions for a positive carbon footprint.

Practical example: How a wholesaler optimized its carbon footprint

The practical implementation of climate-friendly pallet concepts is shown by a real-world example:

Initial situation and challenge

A medium-sized building products wholesaler in southern Germany previously relied on a mixed inventory of wood and plastic pallets. The annual CO₂ balance for the pallet area was 245 tons. Additionally, there were logistical inefficiencies due to different pallet types.

Measurable success

After one year, it became clear:

  • Reduction of the carbon footprint by 72% to 68 tons annually
  • Cost savings of 28% in pallet management
  • Improvement of logistics efficiency by 15%
  • Positive feedback from customers regarding the sustainable concept

This example makes it clear: Climate protection through optimized pallet usage pays off – both ecologically and economically.

Wood panels and alternative wood products: The entire spectrum of sustainable load carriers

In addition to classic wooden pallets, the Wintergroup's climate-friendly portfolio includes further products:

Specialized wooden boards for special requirements

For certain purposes, special wooden boards are more suitable than standard pallets. These are manufactured from the same sustainable raw materials and offer comparable CO₂ benefits:

  • Lightweight one-way boards for export
  • Heavy-duty boards for industrial applications
  • Hygienic wooden boards for the food industry
  • Customized special solutions for specific logistics requirements

All these variants are characterized by a favorable CO₂ footprint and can be recycled as material or used for energy at the end of their life cycle.

Reducing the CO₂ footprint through targeted pallet selection: Tips for companies

How can companies make their pallet usage more climate-friendly? Practical recommendations:

  1. Switching to certified wooden pallets

Companies that currently use plastic or metal pallets can significantly reduce their CO₂ footprint by switching to certified wooden pallets. The Wintergroup supports the changeover with:

  • Needs-based solutions for various requirements
  • Seamless integration into existing logistics systems

  1. Repair instead of new purchase

An important measure for CO₂ reduction is the consistent repair of damaged pallets. The Wintergroup offers a complete service for this:
