Perspectives on inter - linking impact assessment and green procurement the case of green energy

The construction sector consumes significant quantities of energy and contributes substantially to greenhouse gas emissions. It is imperative that the sector considers a renewable component to its energy procurement. The sector has adopted various policy instruments such as impact assessment and green procurement for improving its environmental performance. Green procurement involves the procurement of services, products and also energy that meet environmental requirements. This paper focused primarily on the conceptualisation of the inter-link between impact assessment and green procurement. Furthermore, interviews were conducted with three fundamental categories of stakeholders that involved client, contractor and energy company. Although the interview responses showed varied perspectives on the inter-link, most of the interviewees acknowledged its need and suggested certain approaches towards establishing the inter-link. The highlighted approach was to consider the use of commercially available environmental certification tools and focus on areas such as partnerships. Future research should examine how environmental certification tools could facilitate the inter-link and how partnerships need to be arranged therein.
