1. Despite growing concern about climate change, there remains a significant gap between individuals' environmental concern and their actual behaviour. Humans' personal relationship with nature is a key contributor to pro-environmental behaviour (PEB), which may account for this gap. Those individuals with high levels of sensory processing sensitivity (SPS), approximately 25%–30% of the population, have a particularly

strong connection with the natural world and have a ‘pause to check’ attitude that may make them more prone to consider future consequences of actions. We hypothesise that (1) a disposition to experience awe, characterizing high SPS, mediates the association between the trait and connectedness to nature (CN); (2) SPS is associated with PEB, and CN mediates the association; and (3) consideration for future consequences also mediates the association between high SPS and PEB.

2. 807 participants completed an online survey including validated measures of SPS, CN, awe, PEB and consideration for future consequences. Correlational and mediationa analyses were performed to test the hypotheses.

3. The study showed that the relationship between SPS and CN was mediated by awe. The relationship between SPS and PEB was independently mediated by CN and consideration for future consequences.

4. Policy implications. The UN Sustainable Development Goals were set to reduce inequalities (SDG 10) by considering individual differences, as well as improving climate action (SDG 13). This study shows that psychological dimensions such as sensory processing sensitivity (SPS) are linked to pro-environmental

behaviour (PEB) through future-oriented thinking and feeling connected with nature. These results also suggest that cultivating connectedness to nature and training those with lower SPS to consider future consequences of actions may be a potential avenue to improve PEB.
