The evidence is clear: to change behavior ‘environmental education’ needs to change its focus – with less emphasis on knowledge and raising awareness (although still needed) and more on competency, action skills and problem solving (Marcinkowski, 2010). This report reviews the evidence base to establish which educational methods are proven to have an impact on behavior. The research is summarized and evaluated to develop a set of recommendations on how to better focus educational activities for maximum impact on individuals, local communities and the wider world. The challenge for educators now is to turn this evidence into reality; to develop and deliver educational resources and experiences that trigger long-term behavior change.
