This thesis investigates decarbonization of the Greek energy sector by integrating EU legislative analysis with quantitative modeling. It assesses Greece’s progress toward climate targets through the combined application of the Kaya Identity and the Logarithmic Mean Divisia Index (LMDI) method, using data from 2000 to 2023.
The study first traces the evolution of European Union climate policy, covering the Emissions Trading System (ETS), Renewable Energy Directives (RED I–II), and the “Fit for 55” package. Also examines how these regulatory milestones have shaped Greece’s national energy and climate planning. Emphasis is placed on the Greek NECP and the policy instruments guiding the phase-out of lignite, renewable deployment, and energy system modernization. Quantitative results show a 33.4% reduction in CO₂ emissions from 1990 to 2020, mainly due to improvements in energy intensity and carbon intensity. Public Energy Spendings, fuel switching, renewable integration, and sectoral restructuring played key roles in this outcome.
The thesis concludes that although Greece has achieved measurable progress, it still faces critical challenges in electrifying end-use sectors, securing grid reliability, and addressing implementation gaps in Just Transition strategies. By combining policy analysis with decomposition modeling, the research offers a structured evaluation of national decarbonization pathways within the broader EU governance framework.
