Discuss options for greening your event with your team.

Produce reusable generically branded events materials that can be used at several events.
Encourage guests to return their name badges as they leave the event.
Reuse badgeholders and use old paper inserts as scrap, then recycle the paper.
Plan menus that use local seasonal produce; this will result in tastier and
environmentally friendly dishes.

Use a meeting room with as much natural light as possible. Delegates
concentration is improved and scarce resources are saved by not using unnecessary electricity.
