With the aim of better evaluating their social and economic role in the community, the members of the Colibri Consortium decided to produce a joint Social sustainability report. They joined forces to measure and represent in a unified manner the main social and economic effects of their operations. The main aim of the report, according to GBS national standard - the Social Sustainability report study group, is to give all the stakeholders an overall picture of the business performance through a process of interactive social communication and supply useful information on the quality of business activities so as to increase the knowledge of the stakeholders and their capacity to evaluate and make choices.
