Principal sustainability components: empirical analysis of synergies between the three pillars of sustainability

Starting from the concept of three fundamental sustainability dimensions (environmental, social, and economic), this study investigated professional contributions to sustainability by means of principal component analysis (PCA). Graduates from the Environmental Sciences program (N = 542) at ETH Zurich described their best professional contributions to sustainable development. Next, they evaluated whether their best practice example contributed to achieving any of the five environmental, social, and economic objectives of the Swiss national sustainability strategy. These judgments served as the basis for a PCA aiming to identify principal sustainability components (PSCs) covering typical synergies between sustainability objectives within and transcending the three fundamental dimensions. Three PSCs capturing important synergies were identified. PSC 1 Product and Process Development reflects how ecological innovation and modernization can generate social and economic benefits and at the same time facilitate the reduction in use of as well as the responsible use of natural resources. PSC 2 Education and Social Economics reflects how educational activities and sociocultural sustainability initiatives can simultaneously promote income and employment, social and human capital, and free personal development. PSC 3 Protection of Nature and Humans covers the synergetic benefits which protection of natural spaces and biodiversity and the reduction of environmental risks have for the protection of health and safety of the population. The study also revealed that integration of environmental, social, and economic aspects is often connected to conflicts between these dimensions. However, contributions which consider the economic situation of future generations or enhance social and human capital achieved considerable integration but showed no inclination toward such conflicts.

How the Bologna reform influenced learning outcomes: analysis of perceived qualifications and professional requirements of environmental sciences graduates

ABSTRACT In the context of the Bologna reform, the Environmental Sciences programme at ETH Zurich was transformed from a Diploma to a Masters degree programme. In a comparative secondary analysis of graduate surveys of the last homogeneous cohort of Diploma graduates (N = 85) and two Masters cohorts after the reform (N = 108), this study investigated the qualifications required by graduates in their professional activities and matched them with the level of qualification acquired at university. It concluded that graduates’ general skills meet professional requirements better after the reform. However, for two out of five domain-specific skills (knowledge of legal aspects, interdisciplinary knowledge) ratings of skill acquisition declined significantly. Nonetheless, Masters graduates showed a slight or substantial knowledge and skills advantage for seven of the eight skills of the programmes qualification profile that were addressed in the survey. The basic quality of the sustainability oriented programme has thus been maintained.
