The UN Intergovernmental‘s Panel on Climate Change has a lot to say about how cities are affected by climate change and about what urban areas can do to cut emissions.

These finding have been summarized and simplified in a briefing by the European Climate Foundation, Local Governments for Sustainability (ICLEI) and the University of Cambridge.

Climate action in cities is crucial because most of the world’s economic activities take place in urban areas, and most global greenhouse gas emissions result from activities such as industry, heating and transport.

In additon, more than half of the world's population already lives in cities. This figure is likely to increase to 70% by the middle of the century, with people in developing countries the most vulnerable to the impacts of climate change.

The authors point out that trillions of dollars will be needed to make cities more resilient against impacts such as rising sea levels.

They also say that many of the solutions to reduced build resilience and reduce greenhouse gas emissions are highly cost effective.

For example, more green zoness and wind corridors can help to reduce temperatures and improve the quality of life. And insulating old buildings can reduce heating bills by as much as 90%, at the cost of as little as 100 US dollars per square metre.
