In 1996 the Technical University of Catalonia (UPC) adopted an Environment Plan which incorporated classical technical education, promoting multidisciplinary environmental research, and improving the environmental performance of university life as a whole. This paper outlines the first environment plan (1996-2001). It discusses its encouraging results and consequences, and describes how it was the main motivation for the design of a second environment plan for the period (2002-2005). The paper pays special attention to the curriculum greening experience of UPC: six years ago the university decided to start greening its entire range of courses, over a wide range of technical and scientific areas. The paper explains the most relevant projects, and attempts to evaluate their effectiveness in improving the environmental performance of the university. (Contains 13 figures and 4 notes.)
