The global halal market is rapidly expanding, providing opportunities for countries to diversify their economies and sustain their well-being. Brunei Darussalam has recognised the potential of the halal industry in achieving a future that is not dependent on oil and gas and aligning with its national development strategy, Wawasan Brunei 2035 (Brunei Vision 2035). In this context, Brunei’s halal industry must develop further and innovate in order to optimise its potential. This study employs a qualitative research design and environmental scanning techniques to identify the internal and external factors influencing the halal business ecosystem in Brunei. The findings are analysed using a SWOT matrix analysis to determine the strengths, weaknesses, opportunities and threats of incorporating the halal industry with the United Nations Sustainable Development Goals (SDGs). The study reveals that the halal industry can contribute significantly to a number of SDGs: no poverty; zero hunger; decent work and economic growth; and sustainable consumption and production. The findings provide future scholars, policymakers and researchers with a valuable resource for making well-informed decisions regarding halal industry development in Brunei. Overall, the study highlights the importance of leveraging the halal industry to achieve sustainable economic growth while advancing the SDGs.
