Those problems were also visible during the execution of inter-administrative agreement for the identification, analysis and systematization of environmental conflicts in the metropolitan region, signed by the Área Metropolitana del Valle de Aburrá and Universidad Nacional in 2007. Therefore, the efforts of the diverse people and institutions involved were focused, designing a participative planning process called “Plan SAC” that covers social, environmental and communications management. It includes, in an active way, companies, communities and the State and has, by making transparent communications, achieved good results and many lessons about strengthening social and environmental responsibility were successfully learned during the last two years. These good results and lessons have been beneficial for companies, the communities influenced by them and for the environmental authorities.esGestión socialCorporación Universitaria LasallistaÁrea Metropolitana del Valle de AburráPlan de gestión social, ambiental y de comunicaciones (Plan SAC)Gestión ambientalGestión socialComunicaciónArticle
