C 40 was advocated by the Mayor of London and established in 2005 to create a network of the world's large cities dedicated to working together to reduce greenhouse gas emissions.The Tokyo Metropolitan Government became a member of this network in December 2006, with the aim to learn from the best practices of the world's cities in reducing emissions and use this knowledge for the formulation of metropolitan policies, as well as to promote Tokyo's pioneering climate change measures and technologies to the cities of the world.
* Participating Cities (As of Jan., 2010. 40 member cities and 17 affiliate cities)

International experts and senior officials were invited to attend the conference, and we discussed not only measures to reduce carbon dioxide emissions but also adaptation measures to protect our lives and society against the effects of global warming.
