“…More importantly, Xi'an is one of the 46 key cities identified by the Ministry of Housing and Urban-Rural Development of China (MHURD) to promote municipal solid waste selective collection [31]. In addition, as the largest developing country in the world, the experience of Chinese cities in waste management has important reference value for sustainable development in other developing nations [32,33]. Following the requirements of MHURD, in May 2019, the City Management Committee of Xi'an announced that it was introducing a policy called the "Implementation scheme of domestic waste selective collection in Xi'an in 2019" [34].…”

Understanding why people do or do not perform household waste separation is a vital premise for designing relevant policies to promote waste management. As such, in this paper, an empirical study was carried out to explore the impacts of both rational choice and altruism factors on residents’ household waste separation behavior. Through the analysis of the survey sample (n = 1102) from Xi’an, China, using structural equation modeling, the main findings suggested that (i) the rational choice model can better explain such behavior, (ii) the altruism factor cannot directly affect household waste separation behavior, (iii) the altruism factor is highly correlated with the attitude determinant of household waste separation behavior, and (iv) rational choice models incorporating the altruism factor may have better explanatory efficacy. After that, some factors influencing residents’ altruism to household waste separation were identified. The main aim of this study was to compare two different tendencies in explaining sustainable behavior and help to find a better framework for behavior analysis.

“…Naveed [19] integrated an energy-water system and stated that Hydropower can optimize the energy-water system. Two of the main influential factors in energy emissions included low water-use efficiency and the rapid growth of the GDP, and the change in energy and carbon emissions was determined by water resource utilization and the economic structure [20].…”

The water–energy–carbon (WEC) nexus is a complex, systematic relationship whose influential factors can be interdependent, as well as interactive. Although many action has been taken to achieve the goal of global carbon emission reductions, the disparity and unbalanced among water–energy–carbon systems hundles urban comprehensive development which can not be ignored. Therefore, investigating the water–energy–carbon (WEC) nexus become critical for the global. This study explores the relationship between water utilization, energy consumption, and carbon emissions systematically and take China, one of the largest global carbon emission countries in the world with high energy consumption and unevenly distributed water resources, as an example to investigate coupling coordination model. We selected 2004–2021 data from China’s 30 provinces as our research material, explored them using the entropy weight method, and attempted to study the coupling coordination level of the WEC nexus. Multiple linear regression (MLR) was used to identify the possible influential factors in the WEC nexus. In addition, Spatial correlation of the water-energy-carbon coupling coordination level in 31 provinces and cities has also been researched by Spatial Durbin Model(SDM). The results show that (1) in general, the level of WEC coupling coordination in China is increasing, and the spatial differences between different provinces are large; (2) the lowest level of WEC coupling coordination is mainly distributed in the central region, and the highest level is found in the southwestern region; and (3) water production and hydraulic engineering investment are important factors affecting the coupling coordination of the WEC nexus.
