Good overview. I especially enjoyed: how crucial cities are as drivers for resource consumption and climate change; calculating global material footprints (and www.footprintnetwork.com); and learning that more materials are used for cities and infrastructure than (bio)materials for food production.

Nicely presented and important insights. This helps to structure the drivers in the city and look at different solutions in moving towards energy efficiency, carbon neutrality, renewable energies and circular economy of cities.
