At a time of increased international concern and negotiations for greenhouse gas emission reduction, country studies on the underlying effects of greenhouse gas emission growth gain importance. The case of Turkey is particularly interesting due to rapidly growing emissions, accompanied by a political will and actions to reduce the quick growth. The refined Laspeyres method is used in this study to identify factors\ that accelerate or reduce the increase in Turkish CO2 emissions. A year-by-year decomposition over 1990{\textendash}2007 is carried out at sectoral level based on disaggregated data that is consistent over time and consistent with international standards. Various interesting results on the underlying effects of sectoral emission growth are found. Valuable insights are gained into CO2 impacts of sectoral policies including energy and emission intensities, fuel switching and activity changes. The results yield important hints for the planning of energy and climate policy.

This paper explores Turkish urban households{\textquoteright} willingness to pay (WTP) for CO2 emission reductions expected to result from improvements in power production. A face-to-face questionnaire, with a Contingent valuation (CV) module prepared using the double-bounded dichotomous choice elicitation framework, was administered to 2422 respondents representative of urban Turkey{\textemdash}a developing country with low but rapidly increasing greenhouse gas emissions. The determinants of WTP were identified by considering not only the impact of standard socio-economic factors but also the effects of environmental knowledge, attitudes and behaviour, the relevance of the identity of the collection agent (national versus international institutions) in terms of trust people have towards them, and the degree of perceived participation of others in the realization of the project. Our study confirms the existing literature in demonstrating that WTP figures reported by young and educated people that are active on environmental issues, and who also possess material security and environmental knowledge, are more likely to be high. However, their willingness to make contributions is hampered significantly by their belief that their fellow citizens will not contribute and the general lack of trust in institutions. Overall, this study may be taken as a call to eliminate governance-related uncertainties in climate change deals.

This study presents a policy planning model that integrates learning curve information on renewable power generation technologies into a dynamic programming formulation featuring real options analysis. The model recursively evaluates a set of investment alternatives on a year-by-year basis, thereby taking into account that the flexibility to delay an irreversible investment expenditure can profoundly affect the diffusion prospects of renewable power generation technologies. Price uncertainty is introduced through stochastic processes for the average wholesale price of electricity and for input fuel prices. Demand for electricity is assumed to be increasingly price-sensitive, as the electricity market deregulation proceeds, reflecting new options of consumers to react to electricity price changes (such as time-of-use pricing, unbundled electricity services, and choice of supplier). The empirical analysis is based on data for the Turkish electricity supply industry. Apart from general implications for policy-making, it provides some interesting insights about the impact of uncertainty and technical change on the diffusion of various emerging renewable energy technologies.
