In this study, the GHG emissions from travel activities of attendees of the EGEA annual conference 2013 have been calculated in a GIS-based analysis. The travel activities of the participants result in total GHG emissions of 39,300 kg CO2-eq including both outward and return trip. On average a participant caused GHG emissions of 401 kg CO2-eq. The potential to reduce GHG emissions by substituting flights (-32.6%) and choosing a more central site (-26.3%) has also been assessed.

In this paper, we discuss connections between two important concepts in human geography: discourse and practice. Focussing on the discourse theory of Laclau/Mouffe and the practice theory of Schatzki, we show how both theories are informed by the philosophy of Wittgenstein. After highlighting similarities and differences within their basis interests, we introduce an integrative approach ‘between discourse and practice’ that is illustrated by two empirical examples.
