This master thesis investigates stakeholder perspectives on the adoption of Key Performance Indicators (KPIs) for sustainable construction of buildings. Study includes stakeholder views, preferences, and obstacles regarding adoption of sustainable construction initiatives by utilising a qualitative research approach. Key stakeholder viewpoints on the applicability, usefulness, and relevance are provided through qualitative interviews. Furthermore, stakeholder perspectives towards sustainability and process for development of KPIs are evaluated using qualitative surveys. The study utilises a case study methodology, focusing on a case company that is engaged in the construction of sustainable buildings, and employs a constructivist research design technique to comprehend the individual viewpoints and insights of stakeholders. To obtain in-depth insights, qualitative data gathering techniques like surveys and interviews are employed. A SWOT analysis (Strengths, Weaknesses, Opportunities, and Threats) is also included to determine internal and external variables impacting the adoption of KPIs and to systematically assess stakeholder viewpoints. The research findings shows that various stakeholders hold distinct opinions about the development of sustainable buildings. Although most stakeholders agree that KPIs are crucial for assessing sustainable development, there are significant differences in perspectives about sustainable initiatives in terms of the cost, lack of knowledge, and organizations involvement in decision-making. On the basis of the findings, recommendations are made to the case company to improve stakeholder involvement and collaboration in the development of KPIs for sustainable building construction. These include using standardised frameworks and rules for the creation of KPIs, incorporating stakeholder perspective into data gathering and analysis, and adopting collaborative approaches that engage stakeholders across the KPI life span.  The research contributes to the current discussion on sustainable construction approaches by addressing stakeholder perspectives and reservations, as well as influencing future efforts to develop and carry out effective KPIs in line with the goals and values of the company.
