Alannah Weston, Chairman of Selfridges Group, speaks to business leaders who are reinventing their sectors for a sustainable and just future. This episode explores the shocking world of food waste. More than a third of the world’s food is thrown away and in the developed world, half of food waste takes place at home. Tessa Clarke, CEO of OLIO, an app that redistributes food that would otherwise be wasted, discusses how her business galvanised 50,000 volunteers to tackle waste, and the ways in which society needs to re-think its relationship with food if we are to win the race to net zero. How to Lead a Sustainable Business is brought to you by Selfridges Group and Intelligence Squared. If you enjoy this episode, please take a moment to rate and review us wherever you get your podcasts.
