  • Mayors Summit

    The sixth biennial Mayors Summit, C40’s flagship event, will take place in Ciudad de México from November 30 – December 2, 2016. Hosted by Mayor of Ciudad de México Miguel Ángel Mancera and led by C40 Chair, Mayor of Rio de Janeiro Eduardo Paes, the event draws mayors and leading thinkers from around the world to advance a shared agenda through collaboration and knowledge sharing, and increase visibility about the global potential of climate actions in cities. Previous C40 Mayors Summits have been held in Johannesburg (2014), Sao Paulo (2012), Seoul (2009), New York (2007) and London (2005).

    This year’s Summit will feature the fourth annual C40 Cities Awards, held in partnership with Bloomberg Philanthropies, and taking place in the evening of December 1st. The C40 Cities Awards are granted in 10 categories and provide global recognition for cities that are demonstrating climate action leadership.

    A statement from Mayor of Mexico City Miguel Ángel Mancera and Mayor of Rio de Janeiro Eduardo Paes

    We look forward to welcoming C40 cities and invited guests to the 2016 C40 Mayors Summit, the world’s foremost global gathering of political, business and intellectual leaders focused on forging a low carbon and resilient urban future.

    The Summit will take place one year after the historic COP21 climate negotiations, and will provide a global forum to highlight the progress that cities are continuing to make on climate change through local action and global collaboration. The mayors of the world’s greatest cities will once again demonstrate their leadership in building a broad coalition to act on this most pressing issue of our times. The event will showcase the plans and commitments of C40 mayors and cities ahead of 2020, when global emissions must peak. Indeed, mayors and cities are essential to achieving the ambition of the Paris Agreement, and C40 cities – representing more than 600 million people and 25% of global GDP – have a particularly important role to play.

    The pace and scale of action needs to increase dramatically, particularly in sectors most critical to mitigation and adaptation: buildings, transport, energy, land use and waste. The Summit will serve as an opportunity for cities across the global C40 network to exchange best practices and agree solutions across a range of sectors and thematic areas. We are especially pleased that this year’s Summit will feature the fourth annual C40 Cities Awards, showcasing the world’s most innovative and successful sustainability projects, which will inspire and empower other cities to act.

  • Awards

    The C40 Cities Awards draw international recognition towards the critical role cities are playing as a leading force for climate action around the world, and showcase their success stories so that other cities will be inspired and empowered to act. The Awards Ceremony will take place on Thursday, December 1, 2016 in Mexico City, to coincide with the C40 Mayors Summit.

    This year’s C40 Cities Awards will once again aim to share highly replicable ‘best practices’ across cities and draw attention to outstanding performances that have achieved a high level of environmental success in a challenging context.

    The C40 Cities Awards will give cities prestigious recognition on a global scale at a ceremony attended by Mayors, senior city officials, and international climate leaders, as well as extensive global media coverage.

  • C40

    The C40 Cities Climate Leadership Group, now in its 10th year, connects more than 83 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 citizens. The current chair of the C40 is Rio de Janeiro Mayor Eduardo Paes; three-term Mayor of New York City and current U.N. Secretary-General’s Special Envoy for Cities and Climate Change Michael R. Bloomberg serves as President of the Board. C40’s work is made possible by Bloomberg Philanthropies, Children’s Investment Fund Foundation (CIFF), and Realdania.

  • CDMX

    With a population of approximately 8.84 million people and a metro population of 21 million, Ciudad de México (CDMX) is the country's largest city as well as its most important political, cultural, educational and financial centre. Located in the Valley of Mexico (Valle de México), a large valley in the high plateaus at the centre of Mexico, the city consists of sixteen municipalities.

    Among C40's global network of more than 80 cities, Ciudad de México has been recognised for its leadership in taking climate action. The city government's Climate Action Programme 2014-2020 (Programa de Acción Climática de la Ciudad de México 2014-2020) maximises synergies between actions to tackle climate adaptation, mitigation and resilience, while incorporating social factors like gender equality and the protection of human rights. The city also won the 2013 C40 Cities Award in the Air Quality category for ProAire, a series of comprehensive programmes that over the last two decades have seen impressive reductions in local air pollution as well as CO2 emissions.

    Cities are engines of progress and innovation, which is why CDMX, as one of the largest urban agglomerations in the world, has taken global climate commitments with concrete actions and strategies at local level for balanced and sustainable growth in the short, medium and long term.

    In this context, Ciudad de México is proud to host the 2016 C40 Mayors Summit.

  • Mayor Mancera

    Under the leadership of Mayor Miguel Ángel Mancera, Ciudad de México has prioritised the development of a "Sustainable Capital" committed to low carbon development. His administration seeks to improve the quality of life of its citizens through comprehensive initiatives that preserve the environment, drive economic development and promote social harmony, civic culture and responsible citizen engagement.

    Mayor Mancera was elected in March 2016 to the C40 Steering Committee to represent the Latin American Region. The appointment confirms the city government's commitment to continue advancing concrete local climate actions to address global challenges, and to contribute to C40's leadership in achieving a sustainable urban future.

The C40 Mayors Summit in Mexico City will bring together the largest group of local leaders fighting climate change since COP21. C40 cities around the world are leading the way in reducing carbon emissions and protecting people from potential risks.
