Real Betis defender and former Arsenal player Hector Bellerin says with power comes responsibility after he was named Global Champion at the annual BBC Green Sport Awards. Now in their fourth year, the awards were presented to those who have shown an inspiring commitment to making a difference to sustainability in sport.

We hear from Bellerin as well as Lew Blaustein and Pragnya Mohan. Blaustein is the founder of Eco-Athletes while Mohan is India's top ranked triathlete and helped set up the not-for-profit "Ek Beti, Ek Cycle" (one daughter, one bicycle). They tell John Bennett that athletes are the most influential people in the world but often feel uncomfortable at the thought of talking publicly on environmental issues due to a fear of being branded a hypocrite.
