Embodied carbon for green building rating systems

As climate change concerns are on the rise, it is essential to incorporate the assessment of embodied carbon in green building rating systems. This paper aimed to investigate the incorporation of embodied carbon in green building rating systems. A total of 45 questionnaire surveys were collected amongst certified green professionals and facilitators in Malaysia. Then, data collected was analysed by using descriptive analysis and inferential statistical analysis tests. In this paper, the green building rating systems evaluated for their embodied carbon assessment criteria were LEED, BREEAM, GBI and MyCREST. The study found six general types of embodied carbon in the project life cycle and assessment criteria affected by embodied carbon listed under the current green building rating systems. Solutions to overcome limitations and complications of embodied carbon calculation in green building rating systems were suggested. It is hoped that these findings could provide significant insights to the incorporation of embodied carbon in green building rating systems.
