Biodiversity isn't just about abstract beauty and wonder. It's what future-proofs our world. For Angela Mantilla, armed with a background in biology, this means interrogating how things are produced at one of the world's biggest sports brands. Her Footprint Analytics team was critical to the adidas vision of creating a low-carbon, high-performance shoe – an ambitious moonshot that saw the brand really pushing boundaries. In 2020, they teamed up with eco-friendly shoe specialists Allbirds to create the FutureCraft Footprint, turning a competitor into a collaborator to help achieve this goal. In today's Rebellious Optimists episode, Angela talks about the highs and lows of that FutureCraft Footprint project. She explains how her scientific thinking has helped drive difficult decision-making and why, when it comes to sustainability, it's better to start simple.
