Dragon’s Den star Deborah Meaden and BBC 5 Live’s Felicity Hannah are on a mission to find out how your money matters in the fight against climate change.

This week they tackle fashion. Primark has promised all its clothes will be made of sustainable materials by the end of the decade. Deborah and Fliss talk to the person in charge of making that happen, about cotton, polyester and whether clothes can be cheap AND green.

Plus another great listener question. A busy mum wants to know if getting her shopping delivered is greener than driving to the supermarket.

Featuring: Lynne Walker of Primark, Zainab Ahmed, founder of Pretty Sassy Lady and Professor Shelie Miller of the University of Michigan.
