This thesis delves into the intricate challenges facing The Netherlands as it aims to fulfil its ambitious CO2 emission reduction goals by means of the Regional Energy Strategy (RES) framework. A significant issue highlighted is the emergence of an unintended wealth gap and energy poverty affecting over 600,000 people, which restricts their involvement in the energy transition process. These concerns point to the necessity of comprehensive research to ensure marginalized groups’ active involvement in the energy transition. The core objective of this study is to scrutinize the impact of governance and decision-making practices in the Regional Energy Strategy of Rotterdam The Hague (RES-RDH) on energy justice principles. It seeks to define and understand the concepts of ’local ownership’ and ’equitable participation' within the RES-RDH context. By exploring ways to incorporate energy justice principles into decision-making processes, this research aims to create a comprehensive reference tool to guide the region’s energy transition towards fairness and equity. The investigation employs a literature review, policy document analysis, and interviews to address the main research question and its four sub-questions. The sub-questions focus on defining equitable participation and local ownership in the RES-RDH context, understanding the influence of institutional governance on these aspects, identifying specific challenges in organizing equitable participation, and exploring how energy justice principles can enhance decision-making processes. The findings collectively answer the main research question and contribute to the final reference tool’s development. The theoretical framework incorporates elements of energy justice and public decision-making, enabling a thorough exploration of the equitability and inclusivity of RES- RDH’s decision-making processes. It examines equitable participation, local ownership, and energy justice principles through theoretical lenses, emphasizing the importance of engaging diverse stakeholders, ensuring local community involvement, and balancing power dynamics...
