- Vera Enzi-Zechner co‑lead author says dense cities can stay climate‑safe through water capture, energy generation, biodiversity, and social cohesion from green roofs.
- United Nations projects 2 billion additional urban residents by 2050, intensifying heat‑island effects that green roofs could help offset.
- Moos Water Filtration Plant near Zurich has sustained nine acres of rooftop meadows for over a century, serving as a long‑term habitat for native species.
- Rooftop agrivoltaics enables simultaneous food production and electricity generation on rooftops under solar panels.
Why it matters: City residents and building owners gain cooler, livable spaces as 2 billion more urban dwellers by 2050 intensify heat‑island stress, while municipalities save on cooling costs and boost biodiversity.
