C40 Sao Paulo summit 2011
The Summit provides an opportunity for C40 cities to further clarify and develop the working relationship within the group. This is tended by a number of C40-only meetings.
Each summit brings together an unprecedented number of mayors from major cities, their senior staff and business leaders. Through a comprehensive programme of interactive sessions, delegates can share best practices and identify collaborative projects.
C40 (Climate Leadership Group) was created in October 2005, by Ken Livingstone, Mayor of London at that time, when he invited representatives from 18 leading world cities to meet, discuss and join forces to tackle global warming and climate change.
The C40 initiative has two main objectives: to create cooperation on reducing greenhouse gas emissions and promoting the group actions between companies, public administration and society, against the global climate change.
The biannual event has already been hosted in London (2005), New York City (2007) and Seoul (2009). The current chair of the C40 is Mayor Michael R. Bloomberg of New York.
