Broadcaster and author Kate Humble talks to three remarkable individuals who created leading climate projects, igniting hope and progress, all inspired by events at Hay Festival in previous years.

Film producer Franny Armstrong honed the groundbreaking 1010 Campaign with Ed Miliband on the train back from Hay Festival in 2009; Garry Charnock was inspired by an event at Hay Festival 2005 featuring Sir David King to create the first carbon neutral village, in Ashton Hayes; and Professor Ed Hawkins created the Climate Stripes, illustrating temperature change, as part of the Hay Festival Trans.MISSION project in 2018.

Come along and be inspired to create your own projects and help transform our society to meet the challenges and opportunities of the future.
