Social Agreement
A Path to City Transformation

This is a call for everyone!
The challenge of “waste” is a reality that affects all of us and permeates every aspect of our lives. In addition to environmental and climate issues, we are faced with social, economic and governance problems that make the situation even more urgent and demand immediate action.

The Zero Waste approach proposes practical solutions and represents a transformation towards the sustainability of our cities. By embracing a Social Agreement we build bridges for unity and cooperation between different communities, inspired by the concept of collaborative villages, where everyone comes together for the common good.
This agreement is the key to reducing our environmental impact, promoting a more sustainable economy, reducing social disparities and encouraging innovation, job creation and entrepreneurship.

The participation of all sectors of society is crucial in this process. Zero Waste Cities is the stage where these ideas meet and where reflection turns into action.
Join us in this Social Agreement, the time to act is now!
Zero Waste Cities takes place on a journey through the Museum of the Republic and the Administrative Regions of the Federal District of Brazil.

In the midst of open-air spaces, the structure of the Museum joins the hollows, our meeting point for exchanging knowledge!

You'll find a program full of dynamic activities, demonstrations and experiments, covering the crucial thematic axes of the Social Agreement: Environmental, Economic, Social and Governance.
