This systematic review extends the boundary of prior reviews in the environmental education (EE) field by analyzing publications focused on Latin America and the Caribbean (LATAM). We examined peer-reviewed literature and dissertations/theses in four languages (English, French, Spanish and Portuguese) published between January 2000 and February 2018 to examine outcomes of EE interventions occurring in both formal and nonformal settings among LATAM youth up to age 18 years. Our findings reflect recurring critiques of EE, such as the field's limited empirical research and a bias toward measuring knowledge gain. Our findings also highlight themes specific to LATAM, related to issue-based EE programs, EE versus Education for Sustainable Development, barriers to EE implementation and potential challenges posed by bias, privilege and power in LATAM-based EE research. Access to potentially appropriate publications was limited by weaknesses in search databases. Only a small selection of LATAM countries is represented in publications that met the search criteria, limiting our capacity to draw stronger conclusions about the region as a whole.
