The most commonly used definition of Sustainable Development is: ‘Development that meets the needs of the present, without compromising the ability of future generations to meet their own needs’. Essentially, it is about the quality of life and the possibilities to maintain or improve this quality in the future. Operationalising the concept in global policies resulted in Agenda 21. Seven years later, the Millennium Development Goals (MDGs) were defined, which have been commonly accepted as the international policy framework for development.
