Abstract
This study examined the trends and predictors of children’s pro-environmental behaviors (PEBs) related to climate change mitigation in Japan and China. Analysis of questionnaire survey data (Japan: N = 443, China: N = 452) showed that Readiness to Change and children’s influence in family decision-making were positively associated with PEBs in both countries. However, psychological barriers were negatively linked to PEBs only among Chinese respondents. The relationship between age and PEBs was non-linear in both countries, with an inverted U pattern in Japan and a U pattern in China. These findings underscore the significance of environmental education at school and home in raising awareness and fostering positive attitudes, thus promoting the adoption of environmentally friendly practices among children.
