The study finds that the national percentage requirements set by EU member states are inconsistent with the EU-wide renewable energy target due to cross-country externalities arising from electricity trade and TGCs market prices. This raises doubts about the feasibility of EU renewable energy policy without binding national targets, and provides guidance on how national targets should be shaped.
Several EU member states have introduced national systems of Tradable Green Certificates (TGCs), which stipulate the percentage of total energy consumption to be obtained from renewable sources. The Renewable Energy Directive sets a binding EU-wide target of 32% but without imposing legally binding national targets. To assess incentives for the choice of national percentage requirements we develop a two-country, Cournot duopoly model of the electricity market, with one greenand one blacksupplier in each country. We show that nationally determined percentage requirements do not align with the EU-welfare maximising renewable energy target due to cross-country externalities arising from trade in electricity and the market price of TGCs and examine the direction of misalignment. Our results cast doubts on the feasibility of EU renewable energy policy in the absence of binding national targets and inform how national targets should be shaped.

Impact of carbon emission trading and renewable energy development policy on the sustainability of electricity market: A stackelberg game analysis
Xiaochen Ma, Yanchun Pan, Manzi Zhang, Jianhua Ma, Wen Yang
Summary: This paper examines the impact of combined CET-FIP and CET-RPS policies on the development of renewable energy industry in China. The results indicate that both policies effectively reduce carbon emissions, with CET-RPS policy performing better in the long run for emissions reduction, and CET-FIP policy yielding stronger economic benefits. The impact of these policies varies at different stages of renewable energy development on electricity generation, company profits, and social welfare.

Energy price shocks and current account balances: Evidence from emerging market and developing economies
Mathilde Lebrand, Garima Vasishtha, Hakan Yilmazkuday
Summary: This paper investigates the effects of real energy price shocks on current account balances of emerging market and developing economies. The results suggest that oil price shocks have the most significant impact on the current account balances, and the effects of oil demand shocks are different from those of oil supply shocks. The findings are robust to country-specific factors.

Effects of the promotion pressure of officials on green low-carbon transition: Evidence from 277 cities in China
Tianwei Tang, Xiaojing Jiang, Kaiwen Zhu, Ziyao Ying, Wenyu Liu
Summary: This study investigates the impact of officials' promotion pressure on green and low-carbon transition and its mechanisms. The findings suggest that promotion pressure significantly inhibits the transition, particularly before implementing the environmental inspection system. The study also explores the influence mechanism, showing that promotion pressure leads to a dependence on resource factors, industrial structure, and investment, which restricts the regional green low-carbon transformation.

Impacts of ICT penetration shaping nonworking time use on indirect carbon emissions: Evidence from Chinese households
Junjie Zhang, Shiwei Yu, Xingyi Xiong, Xing Hu
Summary: People's time use is crucial for carbon emissions. The adoption of ICT affects time-use patterns and emissions. The study finds that increasing nonworking time reduces emissions by substituting consumption with time, while increasing the proportion of family members using mobile phones or surfing the internet increases emissions by increasing electricity and communication consumption.

Impact analysis of mergers and acquisitions on the performance of China's new energy industries
Lei Zhu, Jie Shen, Aruna Yeerken
Summary: The development of new energy industries is crucial for a nation's energy transition. Photovoltaic, wind power, lithium battery, and new energy vehicles industries have been active in the capital markets. Through investigating mergers and acquisitions (M&A) activities in these industries in China, we found that they affect firms' short-term market performance and long-term innovation.

Changing determinant driver and oil volatility forecasting: A comprehensive analysis
Qin Luo, Feng Ma, Jiqian Wang, You Wu
Summary: Academic research uses exogenous drivers to improve the accuracy of oil volatility forecasting. Dimension reduction regressions, particularly principal component analysis regression, successfully predict oil volatility at the one-month horizon. Shrinkage methods outperform other methods for medium and long-term forecast horizons. Unsupervised learning (PCA) performs better during periods of oil price decrease, while supervised learning methods (shrinkage methods) significantly improve volatility accuracy. The empirical results also identify several economic indicators that have a significant impact on oil volatility.
