Over the last decades there has been an increasing focus on how to build a sustainable society and in particular on how to design policies that pushes the society into a more sustainable direction. The present paper aims at analysing differences between house buyers when valuing environmental characteristics associated with the house as such. The theoretical framework used is based on the hedonic modelling, but we are also estimating the second stage by assuming a translog utility function. In doing that we are able to estimate the non-marginal willingness to pay for environmental housing attributes and whether environmental aware household have a higher willingness to pay or not. The conclusion to be drawn from the analysis is that there is a positive willingness to pay for environmental attributes. Hence, there may be room for policy measures such as information campaigns. However, it seems to be more effective concerning environmental housing attribute that do not require large investment.
