Pro-environmental behavior: Social norms, intrinsic motivation and external conditions

Pro-environmental behaviors (PEBs) have been linked in the literature to social norms, intrinsic motivation and external conditions. However, no study has jointly analyzed these factors on a cross-country dataset and given a holistic explanation of the variance observed in the adoption rates of PEBs across countries. Using a dataset measuring individual adoption of eight PEBs in the European Union's 28 member states (in 2018), we econometrically test these three groups of factors on a wider scale. We assess the importance of intrinsic motivation as a dominant factor and show how differing levels of intrinsic motivation influence the effectiveness of external conditions, such as monetary incentives and green infrastructures. The results suggest that two-pronged policies, which take into account intrinsic motivation and external conditions, are needed to reach a high observance rate in the population in the short and in the long term. The wider significance of these results for policy is discussed.

Automated summary

Research on pro-environmental behaviors in the EU's 28 member states in 2018 found that intrinsic motivation significantly influences adoption rates, and a two-pronged policy approach considering both intrinsic motivation and external conditions is needed to increase observance rates.
