Our research focuses on the Sao Paulo Metropolitan Area and outlines six CDM projects: Bandeirantes, Sao Joao, Caieiras, Itapevi, Pedreira, and Lara. Twenty-three indicators are proposed, organized into two dimensions: social and environmental. The process of constructing indicators was participatory. The Delphi technique was then applied leading to its validation by experts. The dimensions were subdivided into five topics: participation, emphasizing the participation of associations and cooperatives surrounding landfills; the interface between agents involved, each with different interests; benefits, focusing on the implementation of CDM in the solid waste sector (especially waste pickers' cooperatives and technology transfer); environmental quality monitoring, highlighting the issue of odor; and gas emissions monitoring related to the efficiency of the biogas capture system. The aforementioned results corroborate the importance of the indicators developed based on interdisciplinary and multi-agent approaches which take into account the different stakeholders.
