In October 2005, representatives of 18 leading world cities met in London to discuss joining forces to tackle global warming and climate change. The representatives saw the need for action and cooperation on reducing greenhouse gas emissions and pledged to work together towards achieving that goal.

At the end of the conference, a communiqu was signed which recognised the need for cities to take action and to cooperate on reducing climate emissions. The cities also promised a number of action points, including most notably the creation of procurement policies and alliances to accelerate the uptake of climate-friendly technologies and influence the market place.
