Seven winners will be chosen and their art will be repainted as murals on walls in eight separate British cities including Nottingham, Leicester, Brighton, Stoke, Hackney, Rochdale. You don't have to be living in a particular city to enter that group.
We will also share the winning images and some of the best entrants in our press release, social media accounts and on the Octopus and Imperial website as well as in local art galleries and at COP 26.
All winners mural images will appear on billboards in and around London for a week around COP26 in November.
