The Americans Conference of Mayors Institution (ACM) is an initiative of the II-HE a Non-Profit Organization funded on the United States. The ACM is the institutional non-governmental neither partisan organization of municipalities with any size of population from any country of the Americas, also collectively called America. The Americas encompass the totality of the continents of North America, Central America and South America. Each municipality or city, from the Americas, is represented in the ACM by its current Chief Elected Official, mainly called the mayor.

The ACM Institution hold its Annual Mayor's Summit and its Americas Conference of Mayors Track for Scholars and Professionals every September, starting this 2017. Additional meetings and events are held as directed by the ACM Institution leadership. The ACM Institution Leadership is formed by a Chair, a Vice Chair, a Second Vice Chair, and the President & CEO who is an Ex-Officio Member of the Governing Board, and he is responsible for running and presiding the Executive Committee.

The ACM Institution's mayors agree with a united voice on public and social international best practices and policies. Mayors contribute to the discussion of domestic and international public policies  by serving on one or more of the conference’s committees. The ACM Institution's policies and programs are developed and guided by an Executive Committee and Advisory Board, as well as the  standing committees, committees, and task forces.

During the Annual Summit in September, standing committees and committees recommend policy positions they believe should be adopted by the ACM Institution. Every member attending the annual meeting is given the opportunity to discuss and then vote on each policy resolution. Each city, represented by its mayor, casts one vote. The policy positions adopted at the annual meeting or Summit collectively represent the views of the Americas Conference of Mayors Institution and might be distributed to the Executive or Legislative Branch in any of the participating mayor's states and countries.


In addition to the ongoing work of the ACM Institution's standing committees, and committees mayors are organized into task forces to examine and act on issues that demand special attention such as human rights, migration, democracy, poverty, and so on.
