Signage often is a significant part of an event, particularly ones with a large site layout and content. Signage is commonly overlooked as an area where sustainability practices can be implemented. There are many ways to lower the environmental impact of signage production including making signs which can be reused or recycled, as well as those made from eco-friendly materials.

Where possible, signs should be kept as broad and general as possible so that it can be reused at future events or other events. Signage should only be produced on a needs-basis and the careful handling of signs should be encouraged when appropriate for reusability.

Signage can also be produced using environmentally friendly materials including recycled and biodegradable materials.
