who are we?
Sustainability Events Calendar is a collaborative project by Avery & Brown and Small99 – two UK business focused on making the world a better place.
Together, we saw a gap in the market for a free, simple and accessible events calendar concentrating on the causes we care about.
The site will improve as more events are listed and as it attracts more regular visitors. You can support us by submitting an event and spreading the word!
