The global Muslim population is projected to drive unprecedented demand for halal products, with the halal market expected to reach $2.8 trillion in the coming years. This growth necessitates reliable, traceable, and sustainable halal products. The Blue Economy, which promotes the sustainable use of ocean resources for economic growth and improved livelihoods, presents a promising approach to meet this demand. This chapter underscores the importance of strategic integration and collaboration between Blue Economy principles and halal standards, promoting economic and environmental sustainability while meeting growing consumer demand for ethically sourced halal products. Integrating Fiqh al-Bi’ah, an Islamic environmental ethics framework, with Blue Economy practices enhances the sustainability of halal products, ensuring they are permissible under Islamic law and produced responsibly. Key sustainable practices in the halal industry include humane animal treatment, community engagement, eco-friendly packaging, and ethical supply chains. Despite challenges like varying interpretations of halal requirements and the need for significant investment, opportunities abound for technological advancements and regulatory support.
