| Summary: | Agricultural packaging has a direct impact on the environmental performance of food. The carbon footprint (CF) of two of the most used packaging systems for international transport by road of fruit and vegetables is assessed and compared. Corrugated cardboard boxes (CCB) and polypropylene foldable boxes (PPB) in two different sizes are the object of this study. For the reusable boxes, three different scenarios are considered regarding the number of uses of each box (20, 50, and 100 uses). Product CF ISO 14067:2018 standard is applied, and requirements of ISO 14026:2017 and ISO 14044:2006 are met for a cradle-to-grave CF analysis. Product distribution and return of the empty box are the stages with the most significant impact for PPB over the manufacturing stage. CCB that does not have any returning stage or requirements of sanitation has its main impact in manufacturing. The comparison between both packaging systems of the same size, considering the functional unit and defined scope, points out CCB has a lower CF than PPB.
