The urban sprawl can seem endless, but in reality, cities only cover 3% of global landmass, while accounting for 70% of global emissions. Cities around the world are therefore turning their focus to sustainability. This week, Switched On speaks with Technology & Innovation analyst for BNEF, Kirti Vasta. She will tell us about cities making moves toward sustainability and why now. How different types of cities are approaching the challenge in different ways, and how all cities are using technology as a key component to their strategy.This episode is based on a report titled Digital Technologies for Smarter, More Sustainable Cities. BNEF clients can access this at BNEF on the Bloomberg Terminal, on bnef.com or BNEF Mobile.Switched On is hosted this week by Mark Taylor.See omnystudio.com/listener for privacy information.
