Winning submissions will feature in a campaign celebrating Earth Hour on March 29 2014, alongside work from 26 leading creatives. Last year’s contributors included Google creative director Tom Uglow, photographer Dean Chalkey, 2012 Olympic logo designer Patrick Cox and seven Pentagram partners.
The competition is open to all UK residents aged between 16 and 25. Posters can be about anything that promotes sustainability – from walking more to eating less meat – and can use any medium, from graphic design to photography, illustration, advertising and product design.
The deadline for entries is January 13 and finalists will be invited to a creative mentoring session at Pentagram on January 22 to refine their designs. The top three submissions will be decided by a public vote in February.
Posters (from top): Dean Chalkley, Marina Willer, Karin Rubing and Andrew Rae.
