| Summary: | Green Rating System is utilized as tools to analyze the sustainability of buildings or infrastructures. Improvising green rating system is a continuous effort due to the needs of local implementation of a country. In Malaysia, there are two established rating systems for roads; MyGHI for highways and pHJKR (Roads) for non-tolled roads. Preliminary study on pHJKR (Roads) identified this rating tool assess road sustainability performance only at planning, design & construction stages. This study foresees, it is essential to sustain its engineering and sustainability performance, including carbon assessment under Operation and Maintenance (O&M). Therefore, this paper highlights the relevance and applicability of pHJKR (Roads) in comparison to other establish green road rating tools. The assessment criteria and elements during (O&M) phase are proposed for score development, which extensive research will lead to the establishment of O&M pHJKR (Roads). The data was gathered and analysed from a comprehensive review of current pHJKR (Roads) with a comparison other green road rating index. The expert panel discussion also was utilized to determine suitable sustainability factors. This study, in conclusion providing an opportunity to the enhancement of pHJKR (Roads), which offer a complete cycle of assessment in road project development of road Green Rating System. © Published under licence by IOP Publishing Ltd.
