Pallet carbon footprint is the total greenhouse gas emissions associated with pallet lifecycle.
Detailed Definition
A pallet's carbon footprint adds up greenhouse gas emissions across its life: growing and harvesting the raw material, manufacturing, treatment such as heat treatment, transport, repairs, and end of life through reuse, recycling, burning or landfill. Results depend heavily on assumptions, especially how many trips the pallet makes, how far it travels empty, and how carbon stored in wood is counted. Footprints are usually calculated through a lifecycle assessment following ISO 14040 and 14044, and comparisons are most meaningful per trip or per load shipped.
Why per-trip numbers matter more than per-pallet numbers
A pallet that makes many trips spreads its manufacturing emissions over more shipments. That is why a heavier, longer-lasting pallet comes out ahead of a light one-way pallet in some studies and behind it in others. The answer depends on real trip counts, damage and repair rates, return distances and pallet weight, since a heavier pallet adds fuel use on every trip. When you read a comparison, check the functional unit, the system boundary and where the trip assumptions came from.
Levers that change a pallet footprint
- Reusing and repairing pallets instead of buying new for every shipment.
- Choosing the lightest design that safely carries the load.
- Cutting empty return miles through pooling or a closed-loop program.
- Sending broken pallets to pallet recycling rather than landfill.
- Sourcing wood from certified forests if your program values it.
Reporting pallet emissions
In corporate greenhouse gas reporting, pallet emissions usually fall within Scope 3 under the GHG Protocol, for example in purchased goods or in transportation. Ask suppliers for the method, data sources and assumptions behind any footprint figure they provide, and whether it has been independently reviewed.
Authoritative Sources
- US Environmental Protection Agency (EPA): the federal agency whose Sustainable Materials Management program publishes the waste management hierarchy, which ranks source reduction and reuse above recycling, energy recovery and disposal.
- Forest Stewardship Council US (FSC): the global non-profit setting forest stewardship standards and chain-of-custody certification for pallet wood.

Frequently Asked Questions
Are wood pallets or plastic pallets better for carbon?
There is no single answer. Plastic pallets usually carry more emissions per unit to make but can last for many trips, while wood pallets have lower manufacturing emissions, store biogenic carbon and are widely repaired and recycled. Published lifecycle studies reach different conclusions because they assume different trip counts, weights, return distances and end-of-life routes. Compare results per trip using assumptions that match your own supply chain.
What is biogenic carbon in a wood pallet?
Biogenic carbon is the carbon a tree took from the atmosphere while growing, which stays stored in the wood. Lifecycle methods handle it differently: some credit storage as a temporary benefit, while others treat it as neutral because it is released again when the wood decays or burns. Because this choice can swing the result, a credible pallet footprint states clearly how biogenic carbon was handled.
