The Children's Investment Fund Foundation (CIFF) is an independent, philanthropic organisation. Our staff and Trustees combine the best of business and the best of development, bringing a wealth of experience from both sectors to CIFF's work. We aim to demonstrably improve the lives of children in developing countries by achieving large-scale, sustainable impact. We believe that every child deserves to survive, thrive and mature into adulthood in a supportive and safe environment. However, climate change disproportionately affects children living in poverty in developing countries. A key focus for CIFF is climate-smart urbanisation.

C40 began partnering with CDP (formerly The Carbon Disclosure Project) in June 2011 to bring self-reported data from the world’s largest cities into a comprehensive report on cities’ greenhouse gas emissions and climate risk data. Today, the collaboration includes C40-specific open data portals, premised on the belief that better, more transparent measurement leads to better management. With the right processes in place in partnership with CDP, cities can share strategic insights and reduce their exposure to climate risks and impacts.

World Bank

Partner

In 2011, C40 partnered with the World Bank in an agreement announced during the C40 Mayor’s Summit in Sao Paulo. This agreement will strengthen cooperation between the two organisations by establishing a consistent approach to cities’ climate action plans and greenhouse gas emissions measurement and reporting. Common international metrics will help to better track progress against targets. Equally important, metrics will facilitate cities' access topublic and private sources of capital for climate mitigation and adaptation projects. The World Bank offers a single entry point for C40 cities to access World Bank climate change-related capacity building and technical assistance programs, and climate finance initiatives. This ‘one window’ access helps city governments understand what World Bank resources exist and how to tap into them.
