'''C40 Cities Climate Leadership Group''' is a group of 96 cities around the world that represents one twelfth of the world's population and one quarter of the global economy.<ref name="C40 Cities">{{cite web|title = The Power of C40 Cities|url = http://www.c40.org/cities| access-date= 17 July 2019}}</ref> Created and led by cities, C40 is focused on fighting the climate crisis and driving urban action that reduces [[Earth:Greenhouse gas emissions|greenhouse gas emissions]] and [[Biology:Effects of climate change|climate risks]], while increasing the health, wellbeing and economic opportunities of urban residents.

From 2021, Mayor of [[Place:London|London]], Sadiq Khan, serves as C40's Chair, former Mayor of {{wipe|New York City}} Michael Bloomberg as Board President, and Mark Watts as Executive Director. All three work closely with the 13-member steering committee, the Board of Directors<ref>{{Cite web |title=Board of Directors Archives |url=https://www.c40.org/our-team/teams/board-of-directors/ |access-date=2022-10-07 |website=C40 Cities |language=en-GB}}</ref> and professional staff.<ref>{{Cite web |title=Our Team |url=https://www.c40.org/our-team/ |access-date=2022-10-07 |website=C40 Cities |language=en-GB}}</ref> The rotating steering committee of C40 mayors provides strategic direction and governance.<ref name="What We Do For Cities">{{cite web|url=http://www.c40.org/why_cities |title=What We Do For Cities |date=24 August 2015 |url-status=dead |archive-url=https://web.archive.org/web/20150807070030/http://www.c40.org/why_cities |archive-date=7 August 2015}}</ref> Steering committee members include: London, Freetown, Barcelona, Phoenix, Dhaka North, Tokyo, Buenos Aires, Bogotá, Abidjan, Montréal, Milan and Hong Kong.<ref name="C40 Steering Committee">{{Cite web |title=Steering Committee |url=https://www.c40.org/steering-committee/ |access-date=2022-10-07 |website=C40 Cities |language=en-GB}}</ref>

Working across multiple sectors and initiative areas, C40 convenes networks<ref name="C40 Networks">{{Cite web |title=Networks |url=https://www.c40.org/networks/ |access-date=2022-10-07 |website=C40 Cities |language=en-GB}}</ref> of cities providing a suite of services in support of their efforts, including: direct technical assistance; facilitation of peer-to-peer exchange; and research, knowledge management & communications. 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.<ref>{{cite news|url = https://www.nytimes.com/2016/12/16/science/local-government-climate-change-efforts.html?_r=0|work = The New York Times|date = December 16, 2016|title = As Trump Signals Climate Action Pullback, Local Leaders Push Forward|first = Tatiana|last = Schlossberg|url-access = registration|archive-url = https://web.archive.org/web/20170102234428/https://www.nytimes.com/2016/12/16/science/local-government-climate-change-efforts.html?_r=0|archive-date = 2 January 2017|access-date = 27 February 2017|url-status = live}}</ref>

==History==
C40 started in October 2005 when [[Place:London|London]] Mayor Ken Livingstone convened representatives from 18 megacities to forge an agreement on cooperatively reducing climate pollution and created the 'C20'.<ref name="history">{{Cite web |title=About C40 |url=https://www.c40.org/about-c40/ |access-date=2022-10-07 |website=C40 Cities |language=en-GB}}</ref> In 2006, Mayor Livingstone and the Clinton Climate Initiative (CCI)—led by the efforts of former U.S. President Bill Clinton—combined to strengthen both organizations,<ref>{{cite web|url = https://www.clintonfoundation.org/main/news-and-media/press-releases-and-statements/press-release-president-clinton-launches-clinton-climate-initiative.html|title = President Clinton launches a climate initiative|format = Press Release|date = 1 August 2006|work = Clinton Foundation}}</ref> bringing the number of cities in the network to 40 and helping to deliver projects and project management for participating cities to further enhance emissions reductions efforts.

Serving as C40's first chair, Livingstone established the C40 Secretariat in London, set up the C40 Steering Committee, and initiated the use of C40 workshops to exchange best practices amongst participating cities.<ref name="history" /> In 2008, former Mayor of Toronto David Miller took over as C40 chair. Highlights of his tenure included the Copenhagen Climate Summit for Mayors and the C40 Cities Mayors Summit in Seoul, both in 2009, as well as the launch of practical action initiatives for cities, such as the Climate Positive Development Program and the Carbon Finance Capacity Building program.<ref name="history" />

Three-term Mayor of New York City Michael Bloomberg served as chair from 2010 to 2013. During his three-year tenure, Mayor Bloomberg demonstrated unwavering commitment to building a professional organization and establishing measurable and uniform benchmarks for success, as well as expanding knowledge-sharing between cities and partner organizations with similar priorities. Key milestones during his chairmanship include the full integration of the CCI Cities Program into the C40, and the C40 Mayors Summits in Sao Paulo and [[Place:Johannesburg|Johannesburg]]. Under Mayor Bloomberg's leadership, C40 grew to include 63 cities.

In December 2013 former Mayor of Rio de Janeiro Eduardo Paes became Chair of C40. During his tenure Mayor Paes oversaw the addition of more than 20 new member cities (particularly those in the Global South) several groundbreaking research reports, successful international events, and thriving global partnerships, all of which are helping cities make real contributions to the reduction of global greenhouse gas emissions and [[Finance:Climate risk|climate risk]]s. He also helped launch the [[Organization:Compact of Mayors|Compact of Mayors]] (now the Global Covenant of Mayors for Climate & Energy), put in place the C40 Cities Finance Facility, and oversaw the opening of a permanent C40 office in Rio de Janeiro, at the Museum of Tomorrow.

In 2015, as C40 marked its 10th anniversary,<ref>[http://c40-production-images.s3.amazonaws.com/fact_sheets/images/11_C40_on_its_10-year_anniversary_reOct2016.original.pdf?1475504972 10th anniversary]</ref> cities were crucial voices in shaping and advocating for a strong Paris Agreement—just as city leaders will be crucial in delivering on its ambition going forward. More than 1,000 mayors, local representatives, and community leaders<ref>{{Citation |last=C40 Cities |title=The Climate Summit for Local Leaders, 2015 1 |date=2015-12-05 |url=https://www.flickr.com/photos/c40citieslive/23173399199/ |access-date=2022-10-07}}</ref> from around the world took part in the Climate Summit for Local Leaders, hosted by Mayor of Paris Anne Hidalgo and the UN Secretary-General's Special Envoy for Cities and Climate Change Michael R. Bloomberg during the [[Earth:2015 United Nations Climate Change Conference|2015 United Nations Climate Change Conference]].

In August 2016, Mayor of [[Place:Paris|Paris]] Anne Hidalgo became C40's first chairwoman after being voted in unanimously by the Steering Committee.<ref name="Mayor Hidalgo elected as C40 Chair">{{Cite web |title=Press Release: Paris Mayor Anne Hidalgo Elected as New Chair of the C40 Cities Climate Leadership Group |url=https://www.c40.org/news/press-release-paris-mayor-anne-hidalgo-elected-as-new-chair-of-the-c40-cities-climate-leadership-group/ |access-date=2022-10-07 |website=C40 Cities |language=en-GB}}</ref> Mayor Hidalgo has announced an ambitious agenda for the organization, including plans to focus on securing green financing, supporting compliance with the Global Covenant of Mayors for Climate & Energy, encouraging inclusive and sustainable growth in cities, and recognizing the leadership of women in tackling climate change.

In December 2016, C40 held its sixth biennial Mayors Summit in Mexico City.<ref>{{Cite web |title=Mayors Agree To Bold And Concrete Actions To Meet Paris Agreement |url=https://www.c40.org/news/mayors-agree-to-bold-and-concrete-actions-to-meet-paris-agreement/ |access-date=2022-10-07 |website=C40 Cities |language=en-GB}}</ref> The Global Summit, hosted by Mayor of Mexico City Miguel Ángel Mancera, was attended by 1,400 people, including representatives from more than 90 cities.

The current chair of C40 Cities is Mayor Sadiq Khan of London, UK.

==Membership==
While C40 originally targeted megacities for their greater capacity to address climate change, C40 now offers three types of membership categories to reflect the diversity of cities taking action to address climate change. The categories consider such characteristics as population size, economic output, environmental leadership, and the length of a city's membership.<ref name="Membership Guidelines">{{cite web|format =Press Release|title= C40 Announces New Guidelines for Membership Categories|url = http://www.c40.org/press_releases/press-release-c40-announces-new-guidelines-for-membership-categories|date = 3 October 2012}}</ref>

1. '''Megacities'''

* ''Population'': City population of 3 million or more, and/or metropolitan area population of 10 million or more, either currently or projected for 2025. OR
* ''GDP'': One of the top 25 global cities, ranked by current GDP output, at purchasing-power parity (PPP), either currently or projected for 2025.

2. '''Innovator Cities'''

* Cities that do not qualify as Megacities but have shown ''clear leadership'' in environmental and climate change work.
* An Innovator City must be internationally recognized for barrier-breaking climate work, a leader in the field of environmental sustainability, and a regionally recognized “anchor city” for the relevant metropolitan area.

3. '''Observer Cities'''

* A short-term category for new cities applying to join the C40 for the first time; all cities applying for Megacity or Innovator membership will initially be admitted as Observers until they meet C40's year-one participation requirements, for up to one year.
* A longer-term category for cities that meet Megacity or Innovator City guidelines and participation requirements, but for local regulatory or procedural reasons, are unable to approve participation as a Megacity or Innovator City expeditiously.
