Under the leadership of Mayor Michael R. Bloomberg (currently serving as chair of C40), New York City is firmly on the path toward a sustainable future. Its course was set by PlaNYC, a landmark effort launched in 2007 to drive environmental leadership and infrastructure investment in ways that support economic growth.
Climate change is the most pressing environmental, social and economic problem facing the planet, a problem that is intensifying while global climate treaties and national legislation have hit roadblocks. Driven by the burning of fossil fuels, CO2 in the earth’s atmosphere is rapidly reaching critical levels. This combined with rising temperatures, erratic weather patterns and the depletion of water resources, makes taking action even that much more critical.
The City of São Paulo, host of the 2011 C40 Mayors Summit, has released comprehensive guidelines for its Action Plan for Mitigation and Adaptation to Climate Change , marking a major milestone since the 2009 passage of a citywide bill – the first in Brazil -- to reduce carbon emissions by 30 percent by 2012 (from a 2005 baseline), and address climate-related risks.
