Higher levels of material well-being lead almost inevitably to giving priority to individualism and personal advancement, often at the expense of civic conscience. A proposal for integrating sustainability into the curriculum is presented in the third year of the degree in Early Childhood Education at the Universitat Internacional de Catalunya (UIC). Projects on sustainable food are planned and elaborated to this aim. This study seeks to apply a global and systemic approach to solving socio-environmental problems and to check whether education for sustainable development (ESD) helps to develop and encourage actions that promote sustainable development. Quantitative research was conducted using a pre-test/post-test quasi experimental design separated by a period of didactic training in the project method. The results presented in this article show the students’ sustainability competencies (SC) improve after working on didactic proposals in a global manner. It is concluded that elaborating competencies in education for sustainable development enables an integrated approach of knowledge, procedures, attitudes and values in teaching through promoting the project method in multidisciplinary and transdisciplinary teams, which enhances future teachers’ sustainability competencies.
