The C40 Cities Climate Leadership Group, now in its 11th year, connects more than 80 of the world’s
greatest cities, representing 600+ million people and one quarter of the global economy. Created and led
by cities, C40 is focused on tackling climate change and driving urban action that reduces greenhouse gas
emissions and climate risks, while increasing the health, wellbeing and economic opportunities of urban
The current chair of C40 is Mayor of Paris, Anne Hidalgo; three-term Mayor of New York City
Michael R. Bloomberg serves as President of the Board. C40’s work is made possible by our three strategic
funders: Bloomberg Philanthropies, Children’s Investment Fund Foundation (CIFF), and Realdania.
C40 was founded on the idea that cities can achieve more by working together than acting alone. C40’s
international staff supports mayors of the world’s megacities to deliver bold, ambitious and
transformational action on climate change, through the exchange of ideas, programmes and policies;
world class research; technical expertise; events that convene the world’s foremost climate experts and
communications support to highlight the individual achievements and collective leadership of
cities. Member cities have already committed to reducing their emissions by a total of more than 3
gigatons of C02 by 2030 - the equivalent of taking 600 million cars off the road.
C40 Initiatives and Networks.
Working across multiple sectors and issues, C40 convenes networks that provide a range of services in
support of cities’ climate change efforts. C40 has 17 networks organised under 6 initiative areas covering
the mitigation, adaptation and sustainability topics of highest priority to C40 cities and with the potential
for the greatest climate impact. C40 is also positioning cities as a leading force for climate action around
the world, defining and amplifying their call to national governments for greater support and autonomy in
creating a sustainable future.
C40 networks help cities replicate, improve and accelerate climate action. These city-only working groups
provide for honest knowledge exchange, enabling cities to tap into the global expertise of their peers as
well as connect with technical partners. Through networks, cities find opportunities to undertake joint
projects in areas of mutual interest and benefit. C40 networks also amplify individual city solutions by
providing a global platform for showcasing city successes. The result is that cities' climate actions to
reduce GHGs and climate risks are bolder, more impactful, implemented faster, at a lower cost and with
less resources than if they were to go it alone. No other organisation facilitates such deep connections
amongst city staff across 50+ countries, 20 time zones and 26 languages to accelerate local action with
major global impact.

Government is a slow and tedious process. While it often includes citizen and neighborhood involvement, non-governmental, private organizations have created movements and interesting groups which can create positive change in our cities and towns.
I am fascinated by the way groups are created and how they influence public decision making. This blog merely recognizes them and forwards the description of these groups from their own websites.
