The concept of a sustainable diet has gained global attention with increased climate change issues. A sustainable diet is a food pattern that can be practiced as a climate mitigation strategy. Besides other mitigation strategies, human behavioral changes in choosing a sustainable diet can potentially fight climate change. The potential for reducing carbon footprint by switching to a sustainable diet is substantial. This study aimed to determine the impact of Food Carbon Footprint Activities on the sustainable diet practices of secondary school students. This quantitative study uses a quasi-experimental design of prepost-tests. This study used probability sampling of a mutually exclusive subarea, involving Form Four Biology students at a school within the administration of Hang Tuah Jaya Municipal Council, Melaka. A total of 30 students in the treatment group were given an eight-week Food Carbon Footprint Activities intervention, while 32 students in the control group used conventional learning methods. The Food Carbon Footprint activities use a Problem-Based Learning approach and integrate food carbon literacy in a balanced diet topic in Biology. The independent sample t-test analysis of post-test scores showed that there was a significant difference between the mean score of student's sustainable diet practices in the post-test for the treatment group (M=3.88, SD=0.48) and the control (M=3.66, SD=0.26) and the value t (43.815) = 2.177, p < 0.05. The findings of this study suggest that the Food Carbon Footprint activities with a problem-based learning approach have a positive impact on students’ sustainable diet practices and can be used as a climate change mitigation strategy through climate change education. Thus, a project-based learning approach can be carried out as a further study to identify its effects on students' sustainable diet practices.
