Green port construction has a profound impact on China's international climate commitment to carbon neutrality by 2050. To examine the carbon emission reduction potential of 20 major ports in the Yangtze River Delta port cluster of China, this study takes the perspective of environmental efficiency and employs dynamic exogenous variable DEA in efficiency evaluation. The results show the increasing environmental efficiency of the ports in the Yangtze River Delta, rising from 0.5116 in 2013 to 0.7276 in 2019. Also, there are significant spatial differences in efficiency. After considering exogenous variable, the average efficiency has increased from 0.5537 to 0.6276, indicating that regional green development is a critical factor in port environmental efficiency evaluation. Finally, the overall efficiency of input and output have risen, the slackness of carbon emission shows a trend of decreasing, and there is great potential for reducing carbon emissions from the perspective of port environmental efficiency. The previous studies paid less attention to dynamic efficiency, exogenous variables, and carbon emission. Therefore, this paper is the first comprehensive examination on the carbon emission reduction potential of China's Yangtze River Delta port cluster from the perspective of dynamic environmental efficiency.

Consolidating the results of poverty alleviation and achieving carbon neutrality are serious challenges for global sustainable development, and it is essential to explore the relationship between these goals, and then offer scientific responses. Based on the panel data of 30 provinces in China from 2010 to 2019, this paper conducted the 2SLS model by compromising the merits of the Regression Discontinuity principle with the STIRPAT model to study the interaction between poverty alleviation and carbon reduction. The study found that: (1) the implementation of poverty alleviation aggravates the problem of carbon emissions, and the main mechanism is that poverty alleviation promotes consumption and production by increasing the wealth of farmers, thereby increasing carbon emissions. (2) Carbon reduction weakens the achievement of poverty alleviation significantly, but the mitigation effect presents an "inverted U"-shaped curve, which first increases and then wanes. (3) Farmers' income and the development of rural transportation play a role in acting on the negative effects of carbon reduction. By integrating poverty theory and energy management, this article reveals the complex relationship between two important policies in China and offers relevant policy recommendations, which will not only promote the advancement of rural revitalization but also promote global sustainable development.

Carbon neutrality is an important policy in the current global response to climate change and has been widely recognized by various industries. In the process of promoting carbon neutrality, new energy plays a pivotal role. In this study, the definition and connotation of new energy and its role and specific operation in the energy transition of carbon neutrality are firstly explained. Promoting new energy development requires significant green and low-carbon investments. Taking China as an example, this paper analyzes the opportunities brought by the carbon neutral process to the field of green finance and analyzes the main features and development trends of green finance in China at present. Then this paper proposes policy recommendations to strengthen the development of green finance in China in terms of improving the green financial policy system, enhancing the supply capacity of green financial services, and optimizing the supporting environment for green financial development. Finally, this paper analyzes the measures and experiences of the United States in promoting low-carbon development and proposes countermeasures for China's low-carbon development on the basis of the five major relationships that need attention in China's carbon-neutral process. That is, strengthen the top-level design and improve the regulatory policy system; optimize the energy structure and increase the proportion of clean energy; optimize the industrial structure and reduce energy consumption in key industries; build a complete low-carbon technology system and promote low-carbon technology research and development and demonstration applications, and encourage local conditions to explore low-carbon development paths. The development of green finance can contribute to the advancement of new energy technologies, thus contributing to the achievement of carbon neutrality goals. [ABSTRACT FROM AUTHOR]
