Through the collected empirical material, we develop a framework. This includes the importance of ethical leadership and sustainable leadership for sustainable development. In this study, we want to clarify what the combination of these can contribute to the construction industry in order to more effectively realize the vision of achieving sustainable goals.  Methods: The study was mostly inspired by and used an inductive research approach but also related to an abductive research approach. Furthermore, in this study we have chosen to conduct a qualitative study where six respondents from different companies have been interviewed. All respondents represent managers with human resources responsibilities from the construction industry who have been working with sustainability for at least 2 years. A literature review has been conducted by collecting theories from previous research studies from the databases Halmstad University Library and Google Scholar.  Conclusion: The results of the study show that a leader can work sustainably and ethically towards sustainability by having respect towards his/her employees, supporting them, demonstrating assertiveness, communicating, giving rewards and recognition for good actions. We would also like to point out that the study does not exclude all characteristics that fall outside the grey zone, as the analysis also demonstrated that some situations require a single characteristic from each leadership theory.
