Who bears most responsibility for making football more environmentally friendly?

Nesta McGregor and Sarah Mulkerrins are joined by the BBC's Katie Gornall and David Goldblatt, author of The Ball is Round: A Global History of Football, which focused in no small part on the effect of football on the environment.

We hear from UEFA Director of Sustainability Michele Uva and Sampdoria's Norwegian midfielder and environmental campaigner Morten Thorsby. He wears the number 2 on his shirt representing the 2015 Paris Agreement goal of limiting global warming to below 2°C.
