    Towards Effective Implementation of Carbon Reduction Strategies in Construction Procurement: A Case Study of New Zealand
    (MDPI AG, 30/09/2022) He P; Bui TTP; Shahzad W; Wilkinson S; Domingo N
    In light of climate change, the construction industry plays a crucial part in alleviating carbon emissions and other environmental impacts. The focus on improving the public procurement process poses an important opportunity for the successful implementation of carbon reduction strategies in construction projects. There is a growing body of literature mapping green and sustainable procurement practices in construction. However, previous studies have not treated the implementation of procurement in a particular area, such as carbon reduction, in much detail. This study aims to investigate the implementation of construction procurement incorporating carbon reduction strategies, with a specific focus on the public sector in New Zealand. The research was conducted through 13 semi-structured interviews with construction procurement experts in New Zealand. The results shed light on the current implementation of carbon reduction strategies in construction procurement and its challenges, such as a lack of knowledge and ambiguous procurement guidelines and documents. It also emphasises the importance of (1) well-developed carbon reduction evaluation criteria, (2) specifying a budget for carbon-related initiatives, and (3) the prerequisite of a high level of innovation in the procurement document. The study adds to the rapidly expanding field of carbon reduction construction procurement by providing a deeper insight into the way carbon reduction strategies are effectively implemented in the procurement process.

    Zero Carbon Building Practices in Aotearoa New Zealand
    (MDPI (Basel, Switzerland), 2021-08-01) Bui TTP; Wilkinson S; Domingo N; MacGregor C
    In the light of climate change, the drive for zero carbon buildings is known as one response to reduce greenhouse gas emissions. Within New Zealand, research on climate change mitigation and environmental impacts of buildings has received renewed attention. However, there has been no detailed investigation of zero carbon building practices. This paper undertakes an exploratory study through the use of semi-structured interviews with government representatives and construction industry experts to examine how the New Zealand construction industry plans and implements zero carbon buildings. The results show that New Zealand’s construction industry is in the early stage of transiting to a net-zero carbon built environment. Key actions to date are focused on devising a way for the industry to develop and deliver zero carbon building projects. Central and local governments play a leading role in driving zero carbon initiatives. Leading construction firms intend to maximise the carbon reduction in building projects by developing a roadmap to achieve the carbon target by 2050 and rethinking the way of designing and constructing buildings. The research results provide an insight into the initial practices and policy implications for the uptake of zero carbon buildings in Aotearoa New Zealand.
