She’s now retired from professional sailing competition, but remains very connected to the sport, through her work as the director of sustainability for World Sailing - the sport's international governing body. The organisation is renowned for leading the way in promoting voluntary climate action at every stage of the sport. Alexandra's mission is to make the sport more inclusive and sustainable. In this episode, she talks about her accident, competing professionally, and about how sport is such a useful way to enthuse people about sustainability.

    Professor Tim Minshall heads up the Institute for Manufacturing and Management at the University of Cambridge. The department’s aim is simple: to “help manufacture a better world”. And so Tim has spent hours fostering links between engineering students and companies to help put their new ideas into practice.   He’s recently published the book Your Life is Manufactured which takes a deep dive into the world of manufacturing. He argues that the systems that make things in our modern world are extraordinarily fragile, almost invisible to us and that has worrying consequences.   Tim studied at Cambridge as a PhD student before leaving in 1993 to work at the St John’s Innovation Centre - a business incubator in Cambridge for tech startups. He rejoined the university in 2002 and was named the very first endowed chair in innovation in 2017.     He talks to Sarah about the critical need for industrial sustainability in manufacturing processes and how some of the incredible systems we’ve built are also destroying the planet.  Sustainable Matters … A podcast series full of solutions and optimism for a more sustainable world, brought to you by ISEP: transforming the world to sustainability da0dc943adbb19228647c2252c3cd6e6ea0534b5 Hosted on Acast.

    Solitaire Townsend is the 'Chief Solutionist' at Futerra, the organisation she founded.    Futerra helps companies work towards a sustainable future. Solitaire gave herself that job title because she says if she’s “not serving solutions every day, by default that means she’s serving destruction.”   Solitaire became involved in sustainability action aged thirteen, when she saw a flyer on her school bus saying a nuclear processing company was planning to build near her hometown. After a successful local opposition campaign, she was converted to the business of change making. In this episode she talks to Sarah about working with the world's largest bakery, helping F1 make a commitment to Net Zero and the challenges she faced at the start of her career.    She also talks about how crucial storytelling is to her work, ahead of the publication of her first novel Godstorm, described as a ‘gladiatrix adventure’ set in a petrol-fuelled Roman Empire.    Solitaire has already published The Happy Hero – a book about how to feel good by doing good – and The Solutionists – a handbook for businesses to help create a more sustainable society.    Sustainable Matters is a podcast series full of solutions and optimism for a more sustainable world, brought to you by the Institute of Sustainability and Environmental Professionals (ISEP): transforming the world today for a sustainable future. da0dc943adbb19228647c2252c3cd6e6ea0534b5 Hosted on Acast.
