Abstract

The ethical dimensions of sustainability can be overlooked by academics and project professionals despite ethics being relevant to the achievement of United Nations (UN) Sustainable Development Goals (SDGs). A survey of United Kingdom (UK)’s construction industry leaders is used to identify ethical challenges and solutions, while highlighting the link between sustainability, ethics and individual behaviour. A Theory of Planned Behaviour (TPB) approach is employed to scope out a series of ethical scenarios via an analysis of people, work tasks, culture and training, and subsequently validated via an industry workshop. It is argued that while project tools and techniques fail to engage adequately with ethical issues (e.g., stakeholder management), a proactive examination of attitude, norm, control and intention by project managers at appropriate project times can assist with the identification of potential ethical issues: a TPB-based prompt sheet being presented to assist project managers with their ethics work. The paper makes an original contribution that highlights the relationship between sustainability, ethical working practices and UN SDGs. Despite the relevance of ethics to SDGs, no prior study has used TPB to model ethical scenarios in construction project management.
