C40 is a group of the world's largest cities committed to tackling climate change. On this website you will find news and updates on current C40 programmes, information about each of the cities involved, and links to useful documents.

Cities have a central role to play in tackling climate change, particularly as cities bear a disproportional responsibility for causing it. In fact, cities consume 75 per cent of the world's energy and produce 80 per cent of its greenhouse gas emissions. That is why it is so important for cities to work together, set the agenda on this issue and show leadership on this issue.

Through effective partnership working with the Clinton Climate Initiative C40 will help deliver emissions reductions and better energy efficiency.
