Decision Making of Carbon Reduction Strategies Adoption– A Case Study in Greater Melbourne Region

9 pagesPublished: October 23, 2017


Contractors convert design into reality. They are presumed as a major contributor of carbon emissions from the construction development. Carbon reduction strategies were proposed in previous studies. Nevertheless, contractors were often criticised for standing aloof to adopt them. Some argued that the contractors may not have contractual leverage to challenge the decisions made by the developers and the consultants. Nonetheless, there has been a lack of research that focuses on how different construction project organisations (CPOs) may be affecting carbon reduction strategies adoption. This paper presents a study that investigates the effect of the construction project organisations have on the contactors’ adoption of carbon reduction strategies. An industry survey was conducted in Melbourne, Australia. 200 questionnaires were sent to the registered contractors. Monte Carlo simulations were conducted to examine how the priorities of strategies adoption may be affected by the CPOs. The results indicate that developers and the design consultants are influential to contractors’ decision in adopting those carbon reduction strategies that may incur additional project cost. The results indicate that decisions towards the adoption of strategies may not be swayed towards their effectiveness of achieving carbon reduction. Instead, tightening planning and building regulations might affect decisions.
