This thesis investigates environmental and energy policies that Turkey needs to adopt on its way to a sustainable development path. A comparative-static, multi-sectoral CGE model, TurkMod, is developed in order to analyze the potential scenarios available for the Turkish economy to attain a low-carbon society with a reduced reliance on fossil fuel imports. Domestic energy demand has significantly increased in Turkey over the past decades and this has put a lot of pressure on policy-makers as the economy greatly depends on imports of natural gas and oil as far as current energy consumption is concerned. The CGE model in this study is based on a 2012 energy-disaggregated Social Accounting Matrix (SAM) constructed as a part of this thesis as well. The energy-disaggregated SAM incorporates 18 sectors for production activities, 11 products as commodities, 2 factors of production as labor and capital, 3 institutional accounts as firms, households, and the government, a separate account for taxes on commodities, taxes on production and taxes on different types of factor use, a capital account, and finally the rest of the world (ROW) account. Disaggregating the electricity sector to include 8 different types of power generating sectors (5 of which are renewable energy sources) enables electric power substitution in the model. The energy-disaggregated SAM is further linked with satellite accounts which include data on derived energy demand and greenhouse gas (GHG) emissions.The macroeconomic and environmental impacts of four distinct sets of scenarios are analyzed with respect to the baseline scenario. The first scenario simulates a 30% increase in energy efficiency in the production sectors and the residential sector and evidence is found for reaching the 21% GHG mitigation target set in Turkey’s pledge for Paris Agreement compliance. The second set of scenarios is the inclusion of a medium-level and high-level carbon tax rates for coal, oil and natural gas. The carbon tax scenarios produce significant effects on both emission reduction targets and substituting fossil fuel technologies with cleaner energy types. The third scenario investigates the sectoral and welfare impacts of providing subsidies for renewable energy sources. Turkey has already adopted a scheme where renewable energies are beings subsidized and promoted, however, this policy does not produce the necessary transformation for the Turkish society when utilized solely on its own. The fourth scenario estimates the effects of changes in world prices of energy on the Turkish economy. A 20% increase in world energy prices, i.e. oil, natural gas, and coal, induces substantial changes in the breakdown of TPES and the power-generating sector, but this scenario is a rather hypothetical one as it cannot be suggested as a viable policy option. All in all, these potential energy scenarios have significant and influential impacts on the Turkish economy and its environment. Notwithstanding, a carbon tax policy proves to be the most viable scenario which leads to reduced energy intensities in all sectors, a 21% GHG emissions abatement, and a transformation of the energy sector towards having a low-carbon content along with a reduced reliance on fossil fuel imports. / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished
