Developing a framework for construction-related sustainable development goals projects using a soft systems methodology to mitigate climate change

Purpose There is a rising concern about climate change and its impacts on the physical products of the construction industry. Studies concerning mitigating the impact of climate change on construction-related Sustainable Development Goals (SDGs) projects using a soft systems methodology (SSM) framework are scarce. This study aimed to investigate the root causes of climate change and developed an SSM-based framework to mitigate the negative impacts on construction-related SDG projects in Nigeria. Design/methodology/approach This research used a SSM to understand the impact of climate change on Nigeria’s construction-related SDG projects, using a developed framework. The researchers conducted 40 face-to-face interviews with experts aligned with the SSM stages. The researchers manually analysed the collected data and presented the results. Findings This study shows that, besides the signs of climate change’s negative impacts and the absence of an institutional framework, particularly during the rainy season, it threatens value-driven construction-SDGs projects. The research findings developed a framework to improve the carbon neutrality of construction-related SDG projects, enhance risk management associated with climate change, enhance infrastructure system resilience and sustainability, and improve general operations, thereby improving construction-related SDG projects. Originality/value As part of the research’s implications, this study proposed measures to mitigate the impacts of climate change on construction-related SDG projects. Findings will also encourage stakeholders to consider relevant mechanisms to meet construction-related SDG project requirements and ensure satisfaction, thereby enhancing productivity and excellence.
