Reporting amenity waste reduction for sustainability audits

Pick the measure that fits your records

Choose a unit you already track. Good options are units issued per occupied room night, kilograms of packaging purchased per month, or number of bottles sent to waste. Do not invent a new measure just for the audit; use the figures from your store ledger.

Where your group or your corporate clients use a particular reporting framework, ask them for the data format before you start. It is far easier to collect the right fields from day one than to rebuild three months of records later.

Set a baseline of at least three months

Take three months of issue data before the change, at similar occupancy. Record units issued and occupied room nights. Divide one by the other.

For example, suppose a 60-room hotel issued 11,340 miniatures over 90 days with 3,780 occupied room nights. That is 3 units per occupied room night. These figures are illustrative; use your own.

If you did not keep three months of data, use what you have and say so. Even six weeks of consistent records is better than a rough memory. From today, add two columns to your store sheet: units issued and occupied room nights for the day, so next year's baseline is easy.

Measure after the change the same way

After moving some floors to wall dispensers, record the same data. If miniatures issued fall to 1.2 per occupied room night in the third month and bulk refill packs purchased are recorded separately, you can report the change in small bottles issued. Be clear that you are reporting bottles, not total plastic, unless you also weighed the refill containers.

Occupancy swings can hide real progress. Always divide by occupied room nights, never by calendar days, or a busy month will make a good change look bad and a quiet month will flatter it.

Write the method in three lines

• What was counted (units issued from store, by item).
• Period and occupancy used.
• What was not counted (for example, caps, cartons or guest-taken items).

Auditors respond well to honesty about limits. A narrow but verifiable number is better than a broad one that cannot be traced.

Share the method note with the people who produce the data. If the store keeper knows why issue sheets must be accurate, the numbers improve, and the audit becomes a routine check rather than a scramble. Also agree who signs off the figures each quarter, so the report always has an accountable name next to it.

Add the weight if you can

Weigh ten empty bottles and ten caps once, average them, and multiply by units avoided. State the sample size. Ask your supplier for a pack weight in the specification; our refill systems pages list what we can discuss. Do not use a supplier's weight if it differs from what you measure.

A sample reporting paragraph

Here is wording you can adapt, using the illustrative figures from above. "Between January and March, our property issued 3.0 miniature bottles per occupied room night. After refill dispensers were installed on floors two to five in April, issues in May to July fell to 1.2 per occupied room night across the whole property. Counting method: store issue sheets divided by occupied room nights from the property management report. Not included: caps, cartons, bulk refill containers and items taken by guests."

That paragraph is short, tied to records, and open about its limits. Replace the numbers with yours and keep the structure.

What to keep in the audit folder

1. Store issue sheets and purchase invoices for both periods.
2. Occupancy reports for the same dates.
3. The calculation sheet, signed and dated.
4. Photos of the dispensers in service.
5. Supplier specifications for each item.

Repeat the exercise every quarter. For context on how we think about responsible supply, see sustainability. If you need pack data for your files, ask for it with your sample request.

One more tip: ask the auditor early which format they prefer. Some want a spreadsheet, some a signed statement, some photographs of the store and the rooms. Giving the auditor what they need in the form they like takes less time than defending a document they did not ask for. Where figures change after a correction, keep the original and the corrected version, with a note on why the number moved.
