Sustainable hotel procurement: ask for evidence the purchase can use

There is a tendency in sustainable procurement to treat a recognised label as the end of the assessment, on the reasoning that the criteria have already been checked by someone else. The reasoning is sound as far as it goes, and it does not go far enough.

A label answers a question about environmental criteria. It does not answer the questions a procurement decision actually turns on, several of which are equally important and none of which the label addresses.

Does the product perform the service required? A cleaning product that meets environmental criteria but does not clean to the required standard, or a linen that meets criteria but will not survive the property's laundry cycle, is not a sustainable purchase — it is a product that will be replaced sooner, generating more consumption, not less.

Does it work in this operation? A product designed for one context may not suit another. Water consumption of a laundry process, compatibility with existing equipment, staff training requirement and the effect on service times all matter and none is captured by an environmental label.

And what is the total cost? A product with a lower unit price but a shorter service life, higher failure rate, greater maintenance requirement or higher delivery cost is more expensive over its life. Total cost of ownership, not unit price, is the comparison that reflects what the business will actually spend.

The matrix below organises the assessment around four tests, applied to each significant category of purchase. It is a working structure rather than a scoring system, and it is deliberately designed to produce a documented answer for each line.

Three categories account for a large share of a hotel's non-food purchasing, and each has its own version of the four tests.

Linens and textiles are assessed on durability above all, because the environmental argument for a textile is realised over its service life. A product that meets criteria but wears faster than the incumbent may increase consumption rather than reduce it. The tests are therefore the laundry cycle the property actually runs, the expected number of cycles, and the supplier's evidence for it — followed by total cost across the life, not the cost per piece.

Cleaning products and services are assessed on performance first, because a cleaning product that does not clean to the required standard in the property's operations will be supplemented by another product, which defeats the purpose. The relevant checks are the dilution and dosing regime, compatibility with surfaces and equipment, the training the change requires, and the packaging format the property can actually handle.

Amenities and equipment are assessed on the consumption they drive. A refillable amenity system changes the consumption profile substantially compared with single-use packaging and requires operational change to work. Equipment — refrigeration, laundry machinery, air handling — is assessed on the energy and water it consumes across its life and on its maintenance requirement, both of which usually outweigh the capital difference many times over.

The most common failure in procurement evidence is not a poor initial assessment but the loss of currency afterward. Evidence collected at the point of purchase is filed, the contract runs, and the specification quietly changes — a supplier substitutes a material, reformulates a product, or relocates production, and the basis on which the purchase was justified no longer holds.

The remedy is administrative and simple to describe: record each piece of evidence with an expiry or review date, agree with the supplier that changes to specification, formulation or production location will be notified, and set a review trigger for the categories where the claim materially matters. Where the supplier cannot commit to notification, that itself is information about the durability of the evidence.

The scope discipline bears repeating here, because it is the most common error in the category. A label, a certificate or a claim on a brochure describes a specific product or service that has been assessed. It does not describe a supplier's entire range, and it does not describe a portfolio. Where a supplier presents a credential, the useful question is which products it applies to — and the useful answer is a list, not an assurance.
