Delegations from the C40 Cities Climate Leadership Group, the U.S. President and mayors participated in Rio + C40: Megacity Mayors Taking Action on Climate Change. This event aimed at highlighting the climatic actions taken by C40 Cities in order to reduce their emission of greenhouse gases by over a billion tones by the year 2030. Cities aim at reducing their greenhouse gases by 248 Mt by the year 2020.
A new network to help local governments reduce the emission of methane via solid waste management will be launched by C40. The Climate and Clean Air Initiative of the U.S. State Department and the World Bank will support the C40 in establishing this new network. The participating cities will receive technical support from C40's partners. These partners will help the cities develop projects and programs that in turn will help bring down the production of methane gas and promote collaborative work and peer-learning.
A new library included in the C40 will contain the best practices from all C40 Cities. This new library will lead to the development of climate change strategies that can be successfully utilized. To initiate this sharing of practices C40 will be collaborating with the Joint Initiative on Urban Sustainability (JIUS).
Local government leaders and mayors have assembled in Rio to persuade international organizations and national governments to lend their support and finance towards local climate action.
The new protocol will be made available in almost 10 global cities by ICLEI-Local Governments for Sustainability and the World Resources Institute and C40. This protocol will provide technical assistance to the cities and will help local governments to analyze how the GHG footprint can be influenced by the demand for services and goods including GHG footprint.
