Achieving the 17 Sustainable Development Goals (SDGs) set by the United Nations (UN) in 2015 requires global collaboration between different stakeholders. Industry, and in particular engineers who shape industrial developments, have a special role to play as they are confronted with the responsibility to holistically reflect sustainability in industrial processes. This means that, in addition to the technical specifications, engineers must also question the effects of their own actions on an ecological, economic and social level in order to ensure sustainable action and contribute to the achievement of the SDGs. However, this requires competencies that enable engineers to apply all …

Development In Students' Perceptions Of Sustainability And Responsibility As Relevant Aspects Of The Role Of Engineers, Clara Lemke, Ann-Kristin Winkens, Marie Decker, Inanma Elif, Carmen Leicht-Scholten

Research Papers

Engineering and technology-based solutions can address the global challenges associated with sustainable development. In this context, engineers have a substantial responsibility in achieving the Sustainable Development Goals (SDGs). Meeting the challenges of all SDGs influences economic, political and social aspects of human life. However, engineering students’ understanding of sustainability is often limited to its ecological and economic dimension, not taking into account or even neglecting social issues. Therefore, teaching approaches in engineering education should address the different dimensions of sustainability and the responsibility of technological development concerning society.

Exploring The Fabrication Lab Concept For Learning Sustainable Co-Innovation In Industrial Engineering Education – An Action Research Case From Austria, Selim Erol, Alice Grano

Research Papers
