C40 to release new research, includes water data

Today marks the United Nation’s World Water Day 2012. It’s an occasion to think about the intersection of our finite resources, a growing global population and the need to foster sustainable development around the world.

In cities, 75 percent of which are located in coastal areas, and where more than half of the world’s population now lives, Mayors are looking for ways to manage emissions as well as constrained resources, like fresh water supply. At the same time, they need to plan for a host of climate-related risks, including sea-level rise and storm water management.

To manage emissions, resources and risks, cities must measure them. Last year the C40 Cities Climate Leadership Group released groundbreaking, baseline research on the importance and impact that cities are having on climate change. The two reports, CDP Cities 2011: Global Report on C40 Cities and Climate Action in Megacities: C40 Cities Baseline and Opportunities, took the initial step of tackling measurement and transparency in addressing climate change in megacities. As the Rio+20 United Nations Conference on Sustainable Development approaches, C40 and the Carbon Disclosure Project are preparing to release a new, follow up report in June 2012 that expands their joint effort by inviting the world’s most populated cities to report climate data as well as new information on water use and risks.

Data measurement and reporting are a central focus for the C40, and these tools help cities accelerate mitigation of and adaptation to climate change impacts by setting targets, evaluating actions and accessing resources.

“I firmly believe that if you can’t measure it, you can’t manage it. That is true in business and it is true in government. Only by regularly and rigorously measuring and analyzing our efforts can we learn what works, what doesn’t and why, and take effective action.” -- C40 Chair, New York City Mayor Michael R. Bloomberg

Cities are responsible for consuming two‐thirds of the world’s energy. The 58 C40 Cities globally represent 1 in 12 people, 12% of C02 emissions and 21% of GDP. To ensure these cities can better measure both current successes and assess future opportunities for action to address climate change, C40 will continue its partnerships with two leading organizations in the field, the Carbon Disclosure Project (CDP) and Arup. The data and analysis that result from our joint efforts inform the strategic direction of C40 programs and initiatives, helping the organization to create action-oriented networks of cities with common objectives and challenges.
