Sustainable Corporate Event Invitations: Show the Numbers

A guest opens the invitation on the 7:42 train: "Join us for a sustainable corporate event." She forwards it to a colleague. Neither of them knows what was measured, what changed since last year, or who did the counting, because none of that is on the page.

An event does not get greener because the invitation says so. It gets greener when you can name the figure, the year you are comparing against, and the parts you cannot control. That is what belongs on a sustainable corporate event invitation, in plain sentences, next to the date and the address.

Sustainable corporate event invitations start with a number

Write down what you measured and how far the measurement reaches. Venue electricity, guests' transport, the menu. One line each. "A sustainable event" on its own tells a guest nothing they can carry into the next planning meeting. "Thirty per cent less than the last edition" can be repeated by anyone in the room, and checked against the earlier figure.

• What was measured, and how far: venue energy, guest transport, the menu, each on its own line.
• The reference year and who did the calculation, written with a name on it.
• The part you do not control: travel and waste that sit outside the organiser's hands.
• What changes if the event moves: time, meeting point, and how the guest hears about it.

Your invitation is a small slice. Say that before someone else does.

The invitation is a small share of an event's footprint, and saying it out loud earns more trust than hiding it. A printed card with a QR code on it is still paper, so do not close the text with "zero stationery".

The honest version is mixed: a link for the whole list, plus three or four printed copies for the people who will keep them in a drawer.

Green without a figure is just an adjective. A number, a year and a name turn it into something a guest can repeat.

The figure that expires before the event does

Dinner moves from the dining room to the terrace at eight thirty. You change the link, and nobody reprints two hundred cards or posts new envelopes. Time, map, dress code, wording: the guest opens the same link and sees today's version. A WhatsApp correction is quick, but it disappears under a hundred other messages. The invitation is the one place where the current version always sits.

What the RSVP can ask, and what it should not

You set the questions yourself: attendance, name, and whatever you need to know before the day. The answers arrive in one ordered list inside the invitation, so nobody chases confirmations on WhatsApp the week before. Allergies, menus, high chairs, who is coming by train: that still goes in a separate email or on the venue's own site. Guests need a phone, tablet or computer with a connection, and nothing to install. The invitation costs €29.99, one payment, no subscription. The site runs in seven languages and the invitation content can be set per language, which helps when your guest list does not share one.

Your event is already doing the sustainable work. The invitation only has to tell it with the same precision. Try a design for free, write the figures in, and publish the link once the programme is fixed.
