Environmental sustainability is today one of the most concerns. Not many acknowledge our word is in jeopardy and carbon emission is one of the most prominent reasons. Consumption choices cause carbon dioxide emissions, so individual behaviour might be crucial to turn the tables. This paper combines the data on emissions from Ivanova and co-authors (2017) with the data from the European Values Study and investigates the link between household carbon footprint and social capital at subnational level within the EU, by means of regression and spatial analysis. Results show the spatial error model is the one that best fits the purpose, and that social capital exerts just a mild influence on carbon footprint. On the other side, socio-economic factors, together with the intensity of the electricity mix, seem to have the most remarkable effect over the environment.
