Available for over a year

From synthetic fuel to Extreme E, motorsport is getting greener, but is it enough? Delyth Lloyd and Nesta McGregor are joined by the BBC’s chief environment correspondent Justin Rowlatt and chief F1 writer Andrew Benson to discuss the environmental challenges facing a sport seen by many as “a carnival of carbon”. We hear from Formula 1 world champions Lewis Hamilton and Jenson Button plus Ross Brawn, who’s leading Formula 1’s drive towards sustainable fuels that he claims could benefit the whole car industry. And rising star Jamie Chadwick on driving in the Extreme E racing series that’s using electric cars to highlight environmental problems in remote corners of the globe. Producer: Sam Sheringham
