This article deals with an evaluation of some environmental impacts of a normal workday. The aim is to compare the environmental load associated to different standard meals provided by a canteen, and a series of transport options from home to the workplace, adopting the life cycle assessment (LCA) methodology. LCA is a holistic methodology that evaluates the environmental burdens associated to industrial productions or anthropic activities, over the whole life cycle of a product. The environmental load associated to a service is characterized by a number of impact indicators internationally accepted, such as gross energy requirement, global warming potential (GWP), ozone layer depletion and others. The present paper shows the environmental impacts, calculated with the environmental product declaration and the cumulative energy demand methods, associated to some typical food courses and means of transportation. The present analysis considers as subject a generic worker who lives and works in a European urban area. The results highlight how often environmental impacts coming from the lunch, in particular when the menus contain meat, are higher than the ones attributable to the transport. Taking into account the GWP as example, this study assesses how the contribution for producing a single beef steak (120 g) is equivalent to drive a car for ca. 30 km.
