Dialogues between tourism, development and sustainability: the contribution of the World Charter for Sustainable Tourism +20 Ardyllis Alves Soares 1 Luciano Feijão Faculty I. INTRODUCTION Sustainability is one of the most expressive words in international relations. To use natural resources in a responsible way is one of the greatest challenges we face nowadays. Bringing this challenge to the field of tourism, an international Charter was presented in 2015 that offers guidelines towards a sustainable tourism, calling for action by all stakeholders. It is this framework that will be presented and discussed, indicating a relation with tourism, development and sustainability. II. SUSTAINABLE DEVELOPMENT AND TOURISM The relationship between economic development and sustainability has been discussed for some years. Having the 1992 United Nations Conference on Environment and Development (UNCED) as a special focus of this debate 2 , ideas such as environment and sustainability associated with economic development started to be discussed with particular attention. Many policies were created to make their sustainable objectives effective in order to reduce negative impacts of economic development following the aforementioned United Nations (UN) Conference. UN Agenda 21 and the Sustainable Development Goals (SDG) are two of these programmes attempting to change the relations between human beings and the environment, with the goal of achieving a more harmonious and adequate future.
