A new energy-economy-environment modeling framework: Insights from decarbonization of the Turkish power Sector towards net-zero Emission targets
(Pergamon-elsevier Science Ltd, 2024) Kat, B.; Sahin, U.; Teimourzadeh, S.; Tor, O. B.; Voyvoda, E.; Yeldan, A. E.
The power sector plays a crucial role towards decarbonization for many economies, especially in line with the net-zero targets to limit global warming to 1.5 degrees C. Technical constraints intrinsic to the sector, penetration of new technologies, investment and operational costs, and its connections with the rest of the economy make the power sector a complex system to analyze. Although there are numerous studies to integrate bottom-up power sector technology models with top-down macroeconomic models, this study is the first attempt to link the three separate and interrelated models within a single framework: an electricity market simulation model, a generation expansion planning model, and an applied general equilibrium model. The proposed framework is implemented to analyze a feasible decarbonization scenario for T & uuml;rkiye, with a particular focus on the power sector. The results suggest that, given the existing capacity and potential for renewables, T & uuml;rkiye can achieve a coal-phase out by early 2030s, alongside a trajectory towards a full-fledged fossil fuel phase-out in power generation. The results also indicate that while installed capacity and generation of coal-fired power plants are reduced, real GDP and electricity demand can be maintained and the carbon dioxide emissions from the power sector could be reduced by as much as 50% in 2030 compared to 2018 levels.

Beyond the Quest for a Technological Holy Grail: Patterns of Income Inequality and the Household Carbon Footprint in Turkey
(Cambridge University Press, 2025) Gürer, E.; Satloglu, B.; Voyvoda, E.; Erinç Yeldan, A.
Utilizing data on household consumption expenditure patterns and sectorial greenhouse gas emissions, we study the extent of inequality over Turkish households' differentiated carbon footprint incidences. We harmonize the household budget survey data of the Turkish Statistical Institute (TURKSTAT) with production-based gas emissions data from EXIOBASE3 and investigate both the direct and indirect emissions across household-level income strata. Our calculations reveal that the households in the highest income decile alone are responsible for 19.4 percent of the overall (direct and indirect) emissions, whereas the bottom 10 percent of households are responsible for 4.3 percent. We also find that for direct emissions, the per-household average of the highest income decile exceeds that of the lowest income decile by a factor of 11.2. Notably, 87 percent of the indirect emissions budget for the poorest decile is linked to food and housing expenses, underscoring their susceptibility to climate policies. We confer that in designing the net-zero emission pathways to combat climate change, it would not suffice to study the technological transition of decarbonization solely and that the successful implementation of an indigenous environmental policy will ultimately depend upon the socio-economic factors of income distribution strata, indicators of consumption demand, and responsiveness of the individual households to react to price signals. © 2025 The Author(s).
