The present research concerns the determinants of place-specific pro-environmental behaviour, with particular focus on dimensions such as place identity, injunctive and descriptive local social norms, environmental stress, and self efficacy.The relationship between pro-environmental attitudes (and/or behaviours), identity processes (e.g., see Carrus, Bonaiuto, & Bonnes, 2005), and social cohesion (Uzzell, Pol, & Badenas, 2002) has been addressed by previous empirical studies. Also social norms can play an important role in orienting people’s behavioural decisions in everyday life (Schultz et al, 2007). In particular, we argue that those pro-environmental behaviours which have a place-specific basis could be related to place identity processes and to our perceptions about to what the neighbours do or think about it. Recent empirical findings (see Fornara et al, 2011) suggest indeed that social norms of descriptive nature (both subjective, i.e. what significant others do, and local, i.e. what neighbours do) seem to play a key role for promoting a place-related pro-environmental behaviour (i.e. waste recycling). Studies focusing on the link between local identity and negative environmental conditions, have also shown that those who score high on local identity often do not perceive pollution in their environment (i.e., they deny that their environment is polluted as a way to protect their self esteem). Thus, this condition could lead to a biased assessment of environmental conditions/problems reflecting an attempt to maintain a positive vision of one’s own social identity (see Bonaiuto, Breakwell, & Cano, 1996). Other studies suggest that the perception of a negative environmental condition (environmental stress) can drive individuals toward the performance of pro-environmental behaviours (Homburg & Stolberg, 2006; Homburg, Stolberg, & Wagner, 2007). Environmental ‘stressors’ caused by pollution, when mediated by demand-resource appraisal, can trigger the “focus-on-the-problem” of the environment. In particular, this pattern can positively influence individual pro-environmental behaviour (Homburg & Stolberg, 2006). In this research, we assessed the relative impact of psychosocial dimensions such as local identity, perception of local environmental stress, local norms, and self-efficacy on a set of pro-environmental behaviours at the city level. A correlational field study was carried out with residents of three Italian cities (N=200), using standardized self-report measures. Results show that pro-environmental behaviour scores are positively predicted by perceptions of environmental stress and by self efficacy effects. Concerning local norms, results show a significant weight of descriptive norms. Finally, local identity did not show a direct relation to pro-environmental behaviour. The theoretical and practical implications of these results will be discussed in the light of the research literature.
