Chris Boardman

Former Olympic champion Boardman has been a powerful advocate for sustainable transport, primarily cycling. A policy adviser for British Cycling since 2012, he has since become Greater Manchester’s cycling and walking commissioner, then the area’s first travel commissioner. He has helped create an 1,800-mile cycle and walking network plan, with the intention of getting cars and vehicles off the streets and making active travel accessible. At a national level, Boardman is chair of the board at Sport England and in 2022 became the first national active travel commissioner in government. Since he took the role, Active Travel England has announced £200m of funding for cycling and walking schemes, helping to promote healthy travel, reduce emissions and grow the economy. In July, the 56-year-old cycled 550 miles from Manchester to Paris for the Olympic Games to raise awareness of Sport England’s Going for Green Pledge.

Lewis Pugh

Pugh, 54, has redefined the boundaries of endurance swimming and helped change the fate of more than two million square kilometres of ocean. In establishing Lewis Pugh Foundation, he set out to ensure at least 30% of our oceans are protected by 2030. As UN Patron of the Oceans, he is a voice for the ocean and has taken his message to the UK Parliament, Kremlin, UN Climate Summits, Westminster Abbey, universities and corporate conferences. Pugh has also given two different Ted Talks and used lengthy swims to highlight issues, including become the first person to swim the length of the Thames – doing so in 2006 to draw attention to the severe drought in England and dangers of global warming. Pugh was named a Young Global Leader by the World Economic Forum in 2010 and the UN appointed him as its first Patron of the Oceans in 2013.

A former rower, after missing out on the Tokyo 2020 Olympics and retiring in 2021, Wilson focused on her other driving passion – using the power of athletes to drive climate action. She founded non-profit organisation Athletes of the World with former Olympic champion Hannah Mills.
