Football kits and badges have been redesigned to highlight how clubs could be affected by climate change in the near future.
Kyle Harman-Turner, from Climate Clubs, said he wanted to show how rising water levels could affect football grounds.
Ipswich Town, Norwich City and Chelsea are the first to have their kits redesigned, with more to follow.
"Climate problems are the biggest challenge globally, and nothing rallies people like football," he said.
Mr Harman-Turner, 37, said he set up Climate Clubs as a non-profit organisation to combine his two passions - football and sustainability.
