Understanding the connection between knowledge and pro-environmental behaviour (PEB) has been studied extensively. Some research has found there to be a connection between knowledge and PEB. Despite this, there is still a clear knowledge-action gap. This is evidenced by critiques of the knowledge deficit model (Cook & Melo Zurita, 2019) and reviews that have demonstrated that information alone is insufficient to create significant adoption of PEBs (Bergquist et al., 2023). Despite the mixed evidence which demonstrated the relationship between environmental knowledge and PEB is not linear, there is still a large focus on environmental knowledge in public advocacy campaigns and government strategies to address climate change. The present research proposes that part of the reason why research and campaigns focusing on increasing environmental knowledge are not sufficient is their conceptualisation and measurement of environmental knowledge. The vast majority of environmental knowledge assessments and scales are designed to evaluate general knowledge about the natural world and its processes. Our research proposes the development of context-specific environmental knowledge scales to better aid in the development of environmental knowledge-centred campaigns and policies. We developed an environmental knowledge scale aimed at measuring environmental knowledge specific to a UK university (e.g. assessing if individuals know how to participate in sustainable programmes, knowledge of biodiversity on campus and how to protect it, etc.). We developed this scale in partnership with key stakeholders, including the university sustainability office, sustainability advocacy groups and general students. The scale was validated through confirmatory factor analysis and item-response theory. Then, the newly developed context-specific scale was compared with an existing measure of general environmental knowledge. This presentation discusses how researchers can adapt the processes we used to develop context-specific scales with communities they work with and how these scales can be better applied to make environmental public knowledge campaigns more successful.
