Summary: The International Maritime Organization (IMO) has focused on reducing ship emissions and improving energy efficiency through operational measures, including ship speed reduction. This paper evaluates the potential energy efficiency, environmental impact, and economic benefits of implementing speed reduction measures. Container ships of different sizes were studied, and it was found that reducing the service speed to 19 knots can help comply with the energy efficiency requirements for smaller ships, while larger ships must maintain a speed of 21.5 knots or below. The operational carbon intensity indicator (CII) was also evaluated, and it was observed that a rating between A and C levels can be maintained by keeping the service speed at or below 19.5 knots. The annual profit margin of the ship was calculated based on the application of speed reduction measures, considering the size of the vessel and the applicability of carbon taxes.

Summary: This study uses the pilot policy of energy-consuming right trading in China as a quasi-natural experiment to investigate its impact on the economic performance and carbon emissions of firms. The empirical results show that energy-consuming right trading can significantly improve economic performance and reduce carbon emissions. The double dividend effect is more significant in high-carbon emission firms, non-state-owned firms, and prior to the COVID-19 pandemic. The study also finds that the policy has a Porter innovation mechanism, where innovation input contributes to the economic dividend effect and green technology innovation contributes to the environmental dividend effect.

Summary: International trade and agricultural development play critical roles in achieving carbon neutrality. This study examines the agricultural carbon emission performance using the Malmquist index and analyzes the relationship between international trade and agricultural carbon emission performance through a panel data regression model. The findings indicate that China's agricultural carbon emissions have been increasing slowly since 2005 with room for improvement in low-carbon agricultural productivity. Additionally, there is a correlation between agricultural international trade and carbon emission performance, as indicated by the coefficient of total trade in agricultural products. Suggestions are provided for agricultural international trade and the development of low-carbon agricultural production, aiming to provide technical support for carbon neutrality.

Summary: This study applies an improved dynamic undesirable zero-sum-gains slacks-based-measure model to evaluate the CO2 emission reduction scenarios and energy allocation in different provinces of China. It also calculates the optimal allocation values of carbon emission allowances for each province in 2030. The findings show that China's allocation efficiency values for energy consumption exhibited mixed trends during 2015-2019, and most input-output term efficiency values had room for improvement. After four adjustment iterations, the modeled China achieved optimal carbon emission efficiency. The research results can help regulators establish fairer and more effective policy solutions to promote regional synergistic emission reduction and achieve the national goal of peak total carbon emissions.

Summary: This paper constructs a novel stress measurement system for carbon markets and simulates the stress indices of national and pilot carbon markets in China. It finds that the overall carbon market stress is in the shape of W and remains high with frequent fluctuations and an upward trend. The stress levels of carbon markets in Hubei, Beijing, and Shanghai are increasing, while the stress level of the Guangdong market is decreasing. Trading and emission reduction are identified as the main sources of carbon market stress. Additionally, the Guangdong and Beijing markets exhibit more volatile stress fluctuations, indicating sensitivity to major events. Lastly, the pilot carbon markets are divided into stress-driven and stress-release markets, with changing types over time.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
