ABSTRACT: Through all his life, the humans seek happiness. Across the world, people aspire to live happily without fear to something or someone, and in harmony with God or with nature. In a world shaken by economic crisis, natural disasters or armed conflicts, life has shown that to be truly happy, in addition to material wealth, people also need spiritual wellbeing. We need a new paradigm of sustainable development. Economic wellbeing, social and a healthy environment together define the concept of happiness on a global scale. This might be implemented through a generic index named the gross global happiness index. UN, OECD, EC bodies and governments of some countries have understood that only economic indicators are not enough to develop public policies able to find solutions to the problems of the contemporary world. Economic data should be complemented with information designed to measure quality of life not only in material terms. The international community should promote sustainable development capable of ensuring every opportunity to seek happiness. The debates on the subject, held at international level could result, among other things, that the right to happiness should be recognized legally binding. There are already proposals for inclusion in the Charter of Fundamental Rights of the European Union. This paper is a call for continued efforts made by the governments of some countries and several international bodies towards the elaboration of public policies able to lead to sustainable development and improving the quality of life.
