Sports clubs and organisations must raise their game and become leaders in the battle to prevent catastrophic climate change, Sport England chairman Chris Boardman said on Tuesday.
Opening the Sport Positive summit at the Oval cricket ground in London, former Olympic cycling gold medallist Boardman praised work being done by grassroots and professional clubs in Britain, but said sport was still not punching its weight.
"If climate change is a 'threat multiplier', sport can be a 'solution multiplier'. And as a sector, we can choose to help society use this unique gift," Boardman told delegates from across the world of sport.
"But despite some passionate pioneers, as a sector, we aren't yet punching our weight. So, my call to action today is for a mindset shift, and a lifting of our ambition... We must leverage the unique platform of sport and physical activity to win hearts and minds."
The global sports industry has a huge carbon footprint and also finds itself on the frontline of climate change with rising temperatures, flooding and droughts already having damaging impacts across multiple events.
"Sport's carbon footprint and contribution to waste is massive," said the 56-year-old Boardman, who in July cycled from Manchester to the Paris Olympics to highlight environmental sustainability work being done by sports clubs.
British rower Imogen Grant, who won a gold medal in Paris and on Monday was named BBC Green Sports Awards athlete of the year for her role in highlighting clean water initiatives, said athletes were often placed in an awkward position by the demands of their chosen sport.
