Please send the event's sustainability data by Friday
A client's procurement team has added a question to their supplier form: for each event, provide energy consumption, waste generated and diverted, food waste and the proportion of locally sourced food. Your sales manager forwards it to the general manager, who forwards it to the maintenance manager, who has monthly utility bills for the whole building. The kitchen has a waste log on a clipboard. Nobody has anything per event.
So the reply is your sustainability policy PDF and a paragraph of good intentions. The client accepts it this time. Their form next year will be stricter, and other venues on their list may have better answers.
The data exists at the wrong level
Venues measure energy by building or floor, waste by collection, and food by supplier invoice. Events happen room by room and day by day. Getting from one to the other needs a method, and the method needs to be honest about its limits.
- Meters rarely match rooms, so energy per event has to be apportioned.
- Waste collections cover several days and events.
- Food sourcing information is on supplier invoices, not on menus.
- Leftover food is logged inconsistently, if at all.
- Every client asks slightly different questions.
Why a vague answer is becoming a problem
Corporate clients report on their own footprint, and venues are part of that. A venue that cannot answer the question makes the client's reporting harder, and procurement teams notice. The opposite risk is real too: figures that are made up or overstated can come back to hurt you. The goal is data you can stand behind.
We do not give environmental or legal advice, or certify any figures. Your own advisers decide what you publish and on what basis.
How we build per-event sustainability reports
- We map what you already record: meters and sub-meters, waste collection tickets or supplier reports, food supplier invoices, and any kitchen waste logs.
- Where sub-meters exist, readings are captured per day. Where they do not, an apportionment method you choose (by room area and hours, for example) is applied and stated.
- Waste data from your contractor is split by day and by event using a method you approve, and marked as estimated where it is.
- Food sourcing is read from supplier invoices and linked to the menus served at each event.
- Kitchen waste logging is made easy with a quick tablet form per service, so the numbers exist in future.
- A per-event report is produced for clients who ask, with each figure labelled as measured or estimated, and the method explained.
| Figure | Source | Label |
|---|---|---|
| Energy | Sub-meter or apportioned bill | Measured or estimated |
| General and recycled waste | Contractor data split by day | Estimated unless weighed per event |
| Food waste | Kitchen log per service | Measured where logged |
| Food sourcing | Supplier invoices linked to menus | Measured |
What you can send the next time a client asks
A report for their event with clear figures, each labelled with where it came from and how it was calculated. It will not be perfect, and it does not pretend to be. It is honest and repeatable, which is what most procurement teams are looking for. Over time, as more is measured directly, fewer figures need to be estimated.
Signs you need this
- Clients have asked for sustainability data per event.
- Your answer is a policy document rather than figures.
- Energy and waste data exists only for the whole building.
- Kitchen waste is logged on paper or not at all.
- You are unsure what you could honestly claim.
