Higher education institutions have the responsibility to educate engineers who have achieved an ethical moral vision and the necessary technical knowledge to ensure the quality of life for future generations. In relation to graduating sustainable (SD) engineers, three main questions have been developed to guide this book: The first question is “What?” in terms of which competences (knowledge/understanding, skills/abilities and attitudes) engineers should have in relation to Sustainability. The second question is “How?” and focuses on how can the education processes make this learning achievable through the proper pedagogical strategies. The last question is “Where?” and looks at the curriculum and the organizational structure needed to graduate such engineers. An assessment tool that measures the pedagogy and SD competences is developed and case studies are run in 10 SD courses at 5 European technological universities, where more than 500 students have participated. Moreover the different approaches to introduce SD in the curriculum of 17 technological universities are analysed, and 45 experts on teaching SD to engineering students have been interviewed.
