All your communications activities (e.g., how registration and communication with participants are handled before the event, the materials participants receive, the way rooms are set up) have the potential to reduce negative impacts and increase awareness-raising.
Paper use: Before and after the event, minimize the amount of print material in favors of electronic communication. Develop all documents, especially announcements and invitations, in a way that they can conveniently be sent via email and read on computer screens (short and light documents); make sure that an electronic version of all documents is available on the website If you need to print some material, do so in a sustainable way (e.g., by reducing the text and the number of pages, choosing fewer colors, using recycled paper and sustainable ink, etc.).
