In this episode of the Penguin FM Podcast, Mike speaks with Dave Carlos, Director at Just One, a sustainability consultancy with a mission to spark positive change. They explore what sustainability really means for businesses in 2025 and why it’s no longer just about “net zero” targets or green certifications. From integrating ESG into everyday operations to creating a culture that supports change, this conversation is packed with practical advice for leaders, FM teams, and anyone responsible for making buildings work better.
