Urban sustainability issues — Enabling resource-efficient cities
What is this report about? Resource efficiency is now a key objective of the Europe 2020 Strategy. The flagship `Roadmap to a Resource Efficient Europe` initiative (EC, 2011a) sets out a framework to support a shift towards a resource‑efficient and low-carbon economy in many policy areas. It also gives practical guidance on how to achieve such an economy (EC, 2011b). The Seventh Environment Action Programme, `Living well, within the limits of our planet`, also identifies a resource-efficient, green and...

Urban sustainability issues — Resource-efficient cities: good practice
Our current pattern of resource use is leading to the depletion and, consequently, scarcity of natural resources (1), the degradation of ecosystems and volatile and increasing prices of natural resources. On a planet with finite resources, the challenge is to find a way of delivering greater value and more services with fewer inputs (EC, 2011a). Resources are defined as raw materials, such as fuels, minerals and metals, but also food, soil, water, air, biomass and ecosystems (EC, 2011b). Resource efficiency is a...
