Children’s Environmental Communicative Agency for Sustainability: A Structural Equation Model Bridging the Knowledge–Action Gap

This study investigates the psychological and pedagogical architecture predicting environmental communicative agency among 304 primary school students (grades 5–6) participating in a climate change education programme. Aiming to bridge the persistent “knowledge–action gap” in sustainability education, the research identifies the cognitive, emotional, and instrumental pathways that transform children into active agents of low-carbon, pro-sustainability change in their everyday lives. Employing Structural Equation Modeling (SEM) with a latent climatic knowledge literacy construct, the analysis reveals that the latent construct of General Environmental Knowledge, comprising Conceptual Climate Knowledge and Relational-Systems Climate Knowledge, is the strongest direct predictor of Environmental Communicative Agency. Intrinsic curiosity emerged as a dominant driver of practical competence, while future-oriented tools function as the critical mediator between understanding and social action. Together, these mechanisms outline a school-based pathway through which climate literacy and motivation can be converted into household-level behavioural change and intergenerational climate resilience. The findings advocate for a paradigmatic shift from knowledge transfer to building operative sustainability agency, offering a pedagogical roadmap that fosters “constructive hope” and positions children as “trusted messengers” who catalyse intergenerational learning and reverse socialization toward more sustainable lifestyles.
