Somalia possesses significant untapped potential for organic and low-input agricultural production; however, structural, institutional, and infrastructural constraints continue to limit its effective participation in high-value global markets. In contrast, the United Kingdom represents a highly innovative economy with advanced green technologies, established certification systems, and increasing demand for sustainably sourced products. This study examines the potential for environmentally aligned trade partnerships between Somalia and the United Kingdom by identifying complementary value chains and assessing their economic, environmental, and institutional feasibility. The research adopts a traditional literature review approach, complemented by value chain analysis and qualitative synthesis of secondary stakeholder data across agriculture, fisheries, certification, and green technology sectors. The study identifies several high-potential complementary value chains, including organic sesame, pollinator-friendly honey, frankincense and myrrh, small-scale fisheries and seaweed, insect-derived protein, and drought-smart horticulture. Findings indicate that these value chains offer substantial opportunities to support climate mitigation and adaptation objectives through reduced greenhouse gas emissions, enhanced biodiversity conservation, improved water-use efficiency, and strengthened circular economy practices. At the same time, the study highlights critical constraints, including weak infrastructure, limited certification capacity, governance gaps, and exposure to climate risks, which may hinder scalability. The study concludes that with appropriate institutional strengthening, targeted investments, and the adoption of blended financing mechanisms, Somalia–UK eco-trade partnerships can generate mutually beneficial outcomes. Beyond commercial gains, such partnerships provide a practical pathway for aligning trade with environmental sustainability, offering a scalable model for cooperation between low-income, resource-rich economies and high-innovation markets.
