Workers who have green skills can also be considered sustainable human capital. In fact, the process to produce sustainable human capital is closely linked to the curriculum implemented in institutions that offer training for occupations. Polytechnic Malaysia is one of the big institutions in Malaysia that offer Technical Vocational Education and Training (TVET). Focus area 1 (BT1), action plan 5 (PT5) of the Blueprint Polygreen document clearly refers to the lack of green elements in the Polytechnic Malaysia curriculum. Blueprint Polygreen also states the urgent need to implement green practices by incorporating green elements across the curriculum by up to 30%. In response to this, this study was conducted to explore green elements for greening the existing curriculum at Polytechnic Malaysia. The study was conducted using the Fuzzy Delphi Method (FDM). The FDM analysis shows elements of integrity get first ranking in the inventory of green elements in this study. These findings also indicate that the element of integrity is a very important element and should be incorporated in the Polytechnic Malaysia curriculum to enrich students' learning in order to produce sustainable human capital for the nation's needs.
