Mexico City Pact

The Global Cities Covenant on Climate (also known as the Mexico City Pact or MCP) represents a key decision on the part of 138 attendee mayors at the World Mayors Summit on Climate (WMSC), held 21 November 2010 in Mexico City.

Drafting the pact required participation from a number of international organisms that functioned as Summit invitees and partners. It was agreed that previous accords, action plans and climate pacts would serve as a reference for the articulation of an innovative international mechanism focused on the future.

ICLEI Local Governments for Sustainability produced the initial draft, which was presented for consideration to invited mayors, part of an intense diplomatic effort coordinated by the Fundación that involved participation from the Summit’s instigating organizations and partners.

This diplomatic activity included Mexico City Mayor Marcelo Ebrard’s appointing Pact Ambassadors who promoted the accord among members of the scientific, business, civil society, arts and media communities. One such ambassador was Nobel laureate Mario Molina. The last MCP ambassador—appointed 9 March 2012—was Jean-Michel Cousteau. Following observations and comments on the part of mayors, the Fundación Pensar drafted the final document which was signed by mayors at the World Mayors Summit on Climate in Mexico City on 21 November 2010.

The pact is made up of three principal sections. The first is a ten-point summary of cities’ strategic character in the fight against climate change; the second section features ten climate commitments that cities agree to take on; and the third section (which appears as Annex 1) defines the protocols according to which cities document measurable, reportable and verifiable commitment outcomes to the carbonn Cities Climate Registry headquartered in Bonn, Germany.
