“We believe in football being affordable for our fans and are aware of the need for the game to become more focussed on sustainability,” said Brentford chief executive Jon Varney.
“It is only a little thing, but we believe it will help.”
A shirt made from polyester – as most football shirts are – has more than double the carbon footprint of one made from cotton (5.5kg of carbon dioxide per shirt compared to 2.1kg).
Even recycled polyester takes hundreds of years to decompose and can lead to microfibres escaping into the environment.
