The sustainability questions to ask your warehouse partner

Conversations around warehouse selection tend to start the same way: rates, capacity and location. Can the facility accommodate the inventory? Can it meet storage requirements? What will it cost? But something often overlooked is how much sustainability belongs in that discussion. Decisions about energy consumption, product handling and waste have consequences throughout the supply chain and are an essential part of warehouse selection.

When businesses need to build “just in case” inventories ahead of tariff deadlines or potential trade disruptions, finding suitable storage can become a challenge. Refrigerated capacity adds a further constraint. I speak from experience on this one: finding available space that meets the product’s requirements can quickly narrow the options.

While potential customers do not always have the luxury of being selective, limited options make asking the right questions more valuable. Understanding a warehouse’s sustainability practices helps identify operating risks, set expectations and establish where improvements are possible. Those answers should carry weight in the final evaluation, alongside service and price, with clear expectations for what the operator will measure and improve.

Energy consumption

Start with how the building operates. Ask how energy use is measured, who reviews the results and which improvements have been made toward a greener footprint, assuming the operator is on the sustainability bandwagon. Lighting controls, dock seals, equipment maintenance and door management are useful places to begin. I always recommend a facility tour before making any final decisions.

An energy bill alone tells an incomplete story. Consumption needs context, including the building’s temperature requirements, occupancy and activity levels. Ask how the operator distinguishes increased business from declining efficiency. If energy costs are passed through to customers, understanding the calculation helps clarify what the storage rate covers.

Refrigerated facilities warrant closer inspection. Temperature control protects inventory, and the systems behind it require ongoing maintenance and review. Ask about preventive maintenance, refrigerant leak detection and equipment replacement plans. Who receives temperature alarms after hours? What happens if the equipment fails? How are incidents recorded and corrective actions completed?

The goal is to understand how the warehouse manages energy while maintaining required storage conditions. Lower consumption achieved at the expense of product integrity is a poor trade. A credible partner should explain its operating decisions and provide evidence that the facility consistently meets the agreed requirements.

Product damage

Another angle that belongs at the forefront of the sustainability conversation is product damage. Every case lost represents the resources already used to produce, package, transport and store it, while the financial claim captures only part of that loss. Replacement stock may require another production run, a second freight charge and additional handling.

It is essential to review how damage is reported and investigated. Repeated crushed cases, unstable pallets or handling errors need corrective action and should be an automatic red flag for any warehousing customer. Ask whether the warehouse tracks recurring causes and shares that information with customers. The same discussion should cover stock rotation, expiry visibility and the process for flagging inventory that needs urgent attention.

Early communication creates options. A shipper warned about approaching expiry may still have time to redirect stock, arrange an approved donation or adjust sales plans. A notification sent when the product is already unusable leaves far less room to respond. Both parties should agree on alert thresholds and responsibilities before inventory arrives, as responsibility ultimately rests with the warehousing client. This information is also essential for Canadian Food Inspection Agency recalls or inspections. Ensure the warehouse records lot numbers and expiry dates and ships stock on a first-in, first-out basis if instructed.

Minimizing waste

The same goes for waste. What happens to the cardboard, stretch wrap, damaged products and broken pallets once they leave the warehouse? Ask what gets separated for recycling and how the warehouse tracks where it all ends up. Seeing recycling bins during a facility tour is encouraging, but it helps to know what happens after they are emptied.

Discuss who makes the call when a product needs to be disposed of. Does the warehouse need the customer’s approval? How is that decision documented? Agreeing on the process upfront can prevent usable goods from being discarded or damaged inventory from sitting in storage while everyone waits for instructions.

When finalizing contracts and rates, agree on a few things to track together. Product damage, expiry losses, energy use and waste disposal are useful starting points. Keep reporting manageable and make sure both sides understand the numbers. If the warehouse estimates your share of energy use or waste, ask how.

Include these results in regular service reviews. What has improved? Where are problems recurring? What can you work on together before the next meeting? A straightforward report that leads to action is useful. A sustainability questionnaire that nobody looks at again after signing the contract does very little.
