Summary: China, as the largest cement producer and consumer in the world, has experienced significant increases in CO2, SO2, and NOx emissions from the cement industry from 1990 to 2015. However, the introduction of advanced technologies and policy measures has helped in reducing air pollutant emissions, particularly SO2, CO, and PM emissions, while CO2 emissions continue to rise, posing challenges to carbon emission mitigation in the future.

Summary: Turkiye is a major developing country and the second largest cement exporter in the world. This paper focuses on a detailed exergoeconomic assessment of a rotary burner in a cement factory in Turkiye, aiming to improve energy and exergy performance and reduce energy consumption, exergy costs, and environmental impacts. Through real-time data collection from the factory, the energy and exergy destructions, as well as the exergetic cost distributions for the rotary burner, are calculated using the SPECO method. The use of magnesia-spinel composite refractory bricks and the anzast layer formation leads to a 2.71% reduction in SPECO, equivalent to a saving of $2,280,000 and a yearly decrease of 13.74 MtCO(2) emissions.

Summary: Modern marine propulsion systems need to be reliable, energy efficient, environmentally friendly, and economical. Slow steaming is an effective way to reduce fuel consumption and CO2 emissions, particularly for large container ships with a design speed of over 20 knots. This paper analyzes the effects of slow steaming on a container ship with diesel-engine propulsion and investigates different propulsion systems using low-speed and medium-speed marine diesel engines. The analysis concludes that slow steaming can effectively reduce fuel consumption and emissions, but the choice of propulsion system depends on maritime market conditions.

Summary: China's feed-in-tariff policy has driven rapid growth in the photovoltaic power generation industry, but the quality has not improved alongside the expansion. High costs make it difficult to sustain competitiveness, leading to the need for a gradual withdrawal of subsidies. Uncertain subsidy exit policies may hinder R&D, and the government should provide a clear plan for subsidy reduction. In a monopoly market with government-controlled prices, social welfare is higher and total costs are lower compared to a competitive market, which may benefit from technical cooperation to lower costs and increase profits.

Summary: There are common issues in evaluating the impact of shale gas development due to limitations in identification methods, data sources, and advancing exploitation technologies. Studies indicate that the influence of shale gas development on local water supply is not significant, depending on water management methods. Compared with conventional natural gas and other energy resources, freshwater consumption in shale gas exploration is decreasing with technological progress, while its long-term greenhouse gas emissions are greater.

Summary: COVID-19 has had significant impacts on the global economy and environment. Predictions using the Global Economic-and-environmental Policy Uncertainty (GEPU) index suggest that the index will remain stable or decline in the aftermath of the pandemic. Lower economic and environmental policy uncertainty is conducive to global economic and environmental recovery, although the long-term environmental impact of uncertainty may still persist.

Summary: This study examines the long-run trends of gender pay gap (GPG) in urban China from 1988 to 2013 using the Chinese Household Income Project microdata. The research finds that the GPG has been fluctuating and expanding over time, with the average ratio of female to male earnings declining from 85.2% to 79.9%. Various analytical methods, such as OLS regressions, Blinder-Oaxaca decomposition, and Juhn-Murphy-Pierce decomposition, are employed to comprehensively analyze the factors contributing to the GPG. It is observed that conventional human capital variables explain only a small portion of the GPG by 2013, while differences in location, job characteristics, and unexplained factors play significant roles.

Summary: This study investigates the combined effects of the carbon trading system (CTS), stakeholder concerns, and innovation incentive policies on enterprises' green technology innovation. The findings suggest that enterprises' high level of concern with environmental information disclosure leads to a significant impact of CTS on green technology output and proportion. However, government concerns about decarbonization with CTS have uncertain effects on the dimensions of green technology innovation. It is found that fiscal subsidies and R&D funding under CTS are effective ways to improve enterprises' green technology output, but tax returns are the best way to improve all dimensions of green technology innovation. The study also concludes that inclusive innovation policies have a more significant combined effect of CTS compared to differentiated policies.

Summary: Green technology innovation (GTI) and environmental regulation (ER) play a key role in promoting industrial structure transformation. This study uses regional panel data from China to explore the impact of GTI on industrial structure optimization (OIS) and rationalization (RIS) under different ERs. The results show that GTI has heterogeneous effects on OIS and RIS, influenced by environmental regulation and regional characteristics. Additionally, command-controlled environmental regulation (CER) has a significant inhibitory effect on OIS. The study also finds significant threshold effects of ERs on OIS and RIS, indicating heterogeneity. Strengthening GTI is necessary to promote regional coordination and cooperation for green industrial transformation.

Summary: The social contact rate plays a significant role in the transmission of COVID-19, where higher social contact leads to more contagion cases. This study examined 18 countries with the highest number of confirmed cases in the first 200 days after the Wuhan lockdown. A General Dynamic Model was developed to simulate the epidemic under various restriction policies for 500 days since the outbreak. The findings showed that the probability of contagion ranged from 12.52% to 39.39%, and the social contact rates varied significantly among countries, from 18.21% to 96.00%. Developed economies had 3.5 times more effective restriction policies compared to developing economies. The study compared the effectiveness of different policies for disease prevention and discussed the impact of policy adjustment frequency for each country. The recommendation was to maintain the strictest restrictions or adopt alternating tightening and loosening measures, resulting in an average reduction of maximum active cases by 72.45% and 79.78%, respectively.

Summary: This study finds through empirical analysis that digital government can promote regional eco-innovation through the advancement of digital society and digital citizenship. Both formal and informal environmental regulations have a significant positive impact on regional eco-innovation. Informal environmental regulation has a positive moderating effect on the relationship between digital administration and regional eco-innovation, as well as between digital citizenship and regional eco-innovation. However, formal environmental regulation does not moderate the relationship between digital government and regional eco-innovation.

Summary: Managing shale gas resources can lead to various sustainability issues, which can be addressed through the use of Environment, Society, and Governance (ESG) reports to promote responsible natural resources management. The study examines the financial impact of the first ESG report in China on shale gas companies and finds that the report has heterogeneous effects on the market performance of relevant listed companies. The results suggest that the ESG report provides short-term positive returns to its issuer and potential associates, but negatively affects private and smaller companies.

Summary: This research, based on the data of about 73,000 individuals in China, examines the impact of labor transfer caused by foreign product demand on human capital investment. The results show that as foreign product demand increases, more labor transfers from the agricultural sector to the non-agricultural sector. Working in the non-agricultural sector requires higher-level skills and motivates people to invest more in human capital. Furthermore, labor transferring from the agricultural sector to the non-agricultural sector leads to higher income and increases children's human capital investments, exacerbating intergenerational inequality.
