Hello Community members,

C40 has recently released 100 short briefs and case studies of proven climate-smart actions at the municipal level in developing countries.  Amongst the interesting topics covered are transportation (climate friendly technologies such as Bus Rapid Transit), efficient urban energy systems, sustainable solid waste and many more including an issue very close to our hearts... municipal creditworthiness.

Please visit their site and peruse the many topics offered at

"As cities around the world look for ways to implement the Paris Declaration and meet the ambition of the UN Climate Change Conference (COP21), C40 is showcasing 100 real world examples of projects and approaches that have already proved successful in our member cities.

Eleven new C40 Good Practice Guides offer mayors and urban policymakers roadmaps for tackling climate change, reducing climate risk and encouraging sustainable urban development.

With 100 case studies taken from cities of every size, geography and stage of development around the world, the Good Practice Guides provide tangible examples of climate solutions that other cities can learn from.


“Cities are leading the way on climate change, as they proved at COP21 in Paris. But it is not just political leadership that mayors are offering, it is tangible solutions to reduce emissions, mitigate climate risks and deliver sustainable growth for their cities,” says Shannon Lawrence, C40’s Director of Global Initiatives. “As members of C40, our 83 cities understand the value of stealing each other’s good ideas to catalyse and accelerate climate action.”

For cities struggling with torrential rains and flooding, the Climate Change Adaptation in Delta Cities guide offers a range of approaches - including Copenhagen’s innovativeCloudburst Management Plan - to emulate. Rio de Janeiro’s holistic planning for theTransOeste BRT— a case study from the Bus Rapid Transit guide - serves as an example for cities planning a Bus Rapid Transit corridor and trying to measure potential benefits.

"The Good Practice Guides are a great resource that I can put to immediate practical use in planning the emissions reduction plan for the City of Melbourne,” says Kate Noble, Sustainability Officer, Melbourne. "It is also great to share our C40 best practices with outside cities to help them seize the opportunity of acting on climate change and getting the co-benefits as soon as possible.”

The Good Practice Guides identify nearly 70 categories of good practice for climate change actions in energy, transport, solid waste management, urban planning, adaptation and finance. C40 hopes that cities within our network and beyond will be able to adapt and replicate the concrete examples and approaches highlighted in the Guides. This will allow cities to take meaningful action on climate change more quickly, at a lower cost and achieve greater impact than if they were acting alone."

    It is a useful and fruitful data. I would like to ask if my Municipality could be engaged in the C40. I am so interseted in the topics of climate change. Please help us.

  • A great effort ... and excellent output deserve attention and application in most Middle East countries, and the countries of the world. We wish to contribute to its implementation.
