In an increasingly urbanized world, UN Environment Programme (UNEP) and our partners support cities across the world in addressing environmental impacts and integrating the environment into cities’ long-term strategic planning. We focus on buildings and infrastructure, transport, air pollution, waste and water management, biodiversity and ecosystems.

The emphasis is in particular on supporting developing countries to develop and implement policies; policies which support low-carbon, resource efficient and green growth as well as policies on mitigation and adaptation to climate change.

The imperative of environmentally friendly cities is therefore one which is receiving attention and support from numerous branches within UNEP’s Economy Division. For more information on cities in the context of low-carbon, resource efficiency and green growth, refer to the topic of sustainable lifestyles, and the work of UNEP’s Energy Branch.
