About the summit

The World Mayors Summit on Climate (WMSC) will be held on November 21, 2010 in Mexico City, so that mayors from different regions of the world can sign a voluntary Pact (the Global Cities Covenant on Climate “the Mexico City Pact”) that sends a clear message to the international community on the strategic importance of cities in the struggle against climate change.

The WMSC is convened by Mexico City in conjunction with the World Mayors Council on Climate Change (WMCCC), ICLEI – Local Governments for Sustainability and United Cities and Local Governments (UCLG). These organizations unite thousands of authorities and local governments throughout the world.

The WMSC falls within the context of a series of prior efforts undertaken by cities and local authorities to take action against climate change in the world, such as the signing of the World Mayors and Local Governments Climate Protection Agreement (2007), the Local Government Climate Roadmap (2007), the publication of the Copenhagen World Catalogue of City Commitments to Combat Climate Change (2009), the Copenhagen Climate Communiqué (2009), the Dunkerque 2010 Call on Climate Action (2010), the Bonn Declaration of the Mayors Adaptation Forum (2010) and the Climate Summits of Major Cities of the C40, among many other efforts.

The purpose of holding the WMSC is to take a step forward in the level of commitment with the adoption of necessary measures for mitigation of greenhouse gases (GHG) emissions and adaptation to the effects of climate change on the part of cities.

WMSC will contribute to the United Nations Framework Convention on Climate Change (UNFCCC) and to the United Nations Conferences of the Parties (COP), in particular with the COP16 in Cancún, México, which coordinate the climate efforts of national governments. It also shares with the Intergovernmental Panel on Climate Change (IPCC) the need for a worldwide reduction in Greenhouse Gas emissions that keeps the increase of the average world temperature below 2°C by the end of this century.

The first WMSC is being convened for cities. However, this new international mechanism of commitments and negotiations will be open, as of November 22, to the incorporation of other local authorities of the different levels of government corresponding to the diverse forms of national organization that exist in the world.

WMSC has allies that coincide with the project’s general goals and that will take charge of supporting specific actions. Such is the case of Bonn Center for Local Climate Action and Reporting (carbonn), an initiative of ICLEI – Local Governments for Sustainability and United Nations Environment Program (UNEP) – which will prepare and operate the carbonn Cities Climate Registry, where the signatories of the Global Cities Covenant on Climate (the Mexico City Pact) will set forth their commitments; The World Bank, which will organize a Workshop on Financing for Climate Actions in Cities, to explore different direct financing mechanisms for cities which can be built to support the execution of commitments adopted by cities in the Mexico City Pact; and “Fundación Pensar. Planeta, Política, Persona” (Pensar Foundation) which acts as coordinator of all the intellectual, political and organizational efforts for the holding of WMSC and the signing of the Pact in Mexico City.

WMSC is being sponsored by companies that share the Summit’s objectives, including Siemens, Proactiva Medio Ambiente, Telmex and Nissan, among others.

WMSC will also have the participation of three key sectors of society that contribute directly to attaining its goals: 1) scientists; 2) national and international non-government organizations (NGOs); and 3) the private sector, with the participation of entrepreneurs and financing experts.

The Global Cities Covenant on Climate (the Mexico City Pact)

The Global Cities Covenant on Climate, “the Mexico City Pact” consists of two parts: the first mentions considerations as to why cities are strategic in combating global warming: the second establishes a set of voluntary commitments to promote strategies and actions aimed at mitigating GHG emissions and adapting cities to the impacts of climate change.

To establish and follow up on cities’ commitments, the signatories will establish their climate actions in carbonn Cities Climate Registry (CCCR) powered by Bonn Center for Local Climate Action and Reporting (carbonn). The Registry has two sections:

  • Section 1, is for cities that wish to undertake mitigation and climate change adaptation measures and that by signing pledge to take the first steps, such as preparing their emissions inventory, designing and executing a Climate Action Plan, or promoting local laws that favour GHG reduction, among other measures.
  • Section 2, is for cities that already have climate actions in place that are measurable, reportable and verifiable (MRV).

The CCCR will be available online as of October, 2010 so that authorities in cities attending the WMSC can become familiar with it, and can prepare to sign the Mexico City Pact. The initial registry will be open to cities as of November 22, 2010.

The CCCR will provide cities with a sound and transparent instrument for establishing links and negotiations with multilateral, regional, sub-regional and national financing agencies, by having a common methodology supported by scientific and technical criteria that validates their climate actions.

Finally, by signing the Mexico City Pact, the signatories agree to jointly cooperate with the aim of increasing direct access to international climate funding for cities. To explore and to facilitate this process, a Workshop will be hosted by the World Bank in late September 2010 in Washington, D.C. in order to arrive at the WMSC (CCLIMA) with specific proposals.

The first WMSC (CCLIMA) – November 21, 2010

The First World Mayors Summit on Climate will take place in Mexico City on Sunday, 21 November 2010, and will be held in a colonial building with great historical tradition – the Former Palace of the School of Medicine of the National Autonomous University of Mexico (UNAM).

The WMSC agenda will be carried out in three parts:

  1. The Signing Ceremony. This is a high level session in which Mayors can sign the Global Cities Covenant on Climate (the Mexico City Pact).  It includes the opening of the session by Marcelo Ebrard, Mayor of Mexico City and Chair of the World Mayors Council on Climate Change (WMCCC); statements by the international presidents of the organizations convening the event (ICLEI and UCLG); messages from international guests of honour; and statements from selected Mayors representing every region of the world.
  2. Plenary Session. Three plenary panels that include the views of the key stakeholders and partners of cities for the attainment of goals proposed at the Summit: a) Scientific Panel, b) Social Panel and c) Economic and Financial Panel. In these panels, international leaders will reflect on the different ways in which sectors of society can become involved in order to support cities attaining the goals of the Mexico City Pact to combat climate change.
  3. Special events. These will be organized by the sponsors and allies of the Summit and will address topics closely related to the goals of the Summit.

The WMSC (CCLIMA) will be broadcasted to a large audience through the website (www.wmsc2010.org) and in a premise close to the official venue.
