Transparency mechanisms play a critical role in ensuring sustainable and climateresilient natural resource management (NRM), particularly in the face of increasing climate-related challenges. This study sought to assess how Transparency Mechanisms enhance sustainable NRM, focusing on Transparency International-Kenya (TI-Kenya) as a case study. Grounded in Environmental Governance Theory, the research employed a quantitative approach, drawing insights from a diverse range of stakeholders to capture quantitative dimensions of governance effectiveness. The target population was 150 people who included TI-Kenya employees, policymakers, environmental experts, and local community representatives, selected through stratified and purposive sampling techniques. The findings affirmed that sound transparency mechanisms were indispensable in fostering sustainable, climate-resilient natural resource management at Transparency International-Kenya. The study recommended that future research could explore how these corporate governance mechanisms function in more diverse contexts, particularly among smaller grassroots organizations or in different geographical regions facing distinct climate impacts.
