Research on the Effect of Low-Carbon Education on Residents by the Chinese Government

The low carbon living of residents is important for China to achieve the “double carbon goal.” This paper uses the natural language processing technique in machine learning to collect data from 2005 to 2020, constructs the government’s “green will” index and residents’ low-carbon life index, and conducts an empirical study through a static panel model and a dynamic panel model. The study shows that: (a) all cities in the Yangtze River Delta pay more and more attention to low-carbon publicity, but there are individual differences in the degree of attention; (b) in general, the government’s willingness to go green does drive residents to develop a low-carbon life; (c) affluence and human capital growth are positively related to the effect of government low-carbon publicity. Accordingly, the following measures are proposed: increase the government’s low-carbon publicity efforts, deepen education reform, attract high-end talents, strengthen scientific and technological innovation, promote new urbanization, and reduce the marginal cost of carbon emissions.

Numerical study of HTJI on combustion characteristics of neat ammonia engine under atmospheric intake conditions

Low-carbon life is spreading to every corner of the world, but also offers new challenges to the internal combustion engine (ICE). Ammonia (NH3), as a hydrogen carrier and carbon-free fuel, is the key for ICE to being zero-carbon. Hydrogen turbulent jet ignition (HTJI) is thought as an optimal method to overcome the poor combustion performance of ammonia. In this study, the combustion characteristics of a neat ammonia engine with HTJI are numerically studied by addressing the orifice diameter and pre-chamber reactivity. The results show that an optimal orifice diameter is needed to maximize the promoting effect of HTJI on ammonia combustion. The jet flame quenches under small orifice conditions, and no jet flame products under large orifice conditions. When considering the pre-chamber reactivity, the scavenging process leads to a low degree of H2 in the pre-chamber during the compression, which results in low-efficiency ammonia combustion. By increasing the pre-chamber reactivity (hydrogen quantity) of the pre-chamber, the jet flame is advanced and much stronger, resulting in better engine performance. For nitrogen-based emissions, the unburned NH3 emissions mainly depend on combustion efficiency, while NO emissions show an opposite trend. The current results can help find the optimization method of the ammonia engine with HTJI.

Does culture matter for household carbon emissions? Evidence from “confucian” households in China

ABSTRACT Exploring cultural factors in household carbon emissions is of positive significance in promoting low carbon life. This research uses China Household Financial Survey 2015 (CHFS 2015) to investigate how Confucian culture impacts carbon emission of Chinese household. We found that Confucian households have significant lower level of carbon emissions due to the ‘inhibited’ consumption level and the service-oriented consumption structure; Specifically speaking, larger household sizes, stronger propensity to save, and stronger housing preferences lead to Confucian households’ lower consumption level, and an expenditure arrangement favouring education and medical care shapes a service-oriented consumption structure, which is also a low-carbon emissions consumption structure. Furthermore, Confucian ecological ethics did not notably enhance households’ subjective environmental attitudes, but strengthen adaptive behaviours in response to ecological deterioration, thereby reducing household carbon emission levels. Our research contributes fresh evidence and findings to the study of the environmental implications of Confucian culture.

"TGT-Lcarbon" - A Non-Profit Third-party Carbon Fund Platform

In the context of "carbon neutrality" and "carbon peak", energy conservation, environmental protection, and low-carbon life have become the mainstream of society. As a new force in the development of green economy, carbon trading has become an indispensable part of the financial market. There are unlimited business opportunities in the carbon market, and the good development of carbon funds is of great significance to promoting the development of China's CDM projects and enhancing the international competitiveness of the low-carbon economy. At present, government-led public welfare carbon funds are the main driving force in China's carbon financial market. Narrow financing channels have caused China's carbon financial market to face a funding gap, and there is an urgent need for social funds to participate in the carbon financial market. Therefore, this article first analyzes carbon funds and their operating methods; secondly, sorts out the existing domestic and foreign carbon fund transaction types, focusing on domestic carbon funds; and finally, in order to better serve the real economy’s low-carbon emission reduction Develop and better develop China's carbon financial market, and study the role and significance of carbon funds as media investors and financing parties in the financial system.

Impact of Climate Change on Environment and Marine Species of the Artic Ocean

As one of the four oceans on earth, the Arctic Ocean plays a vital role in affecting the ecological environment of the earth. Due to vegetation degradation, natural disasters and human activities, acid rain, global warming and ozone layer destruction as the main forms of climate change have brought serious negative impacts on the Arctic Ocean ecosystem and its environment. Currently, the Arctic Ocean is one of the regions of the world most affected by climate change. Climate change is caused by many factors. Vegetation degradation and atmospheric particulate matter caused by natural or human activities are major contributors to global climate change. Climate change has led to a dramatic rise in Arctic temperatures and increased mercury pollution. Pollution and reduced sea ice are also affecting many plant and animal species. In this paper, the causes of climate change and the effects on the environment and biodiversity in the Arctic Ocean are studied, and the improvement measures are proposed. In the future, people should pay more attention to carbon emissions, advocate low-carbon life, and pay attention to environmental protection. This study provides a theoretical basis for people to pay more attention to the abnormal changes of the Arctic Ocean environment and pay more attention to improving the environment.

How to Promote Green Building Design in the City: Taking the Green Building of Shanghai Museum of Natural History as an Example

At present, China is still in the primary stage of socialist development. With the change of the current global development situation and the concept of "sustainable development" put forward in the 1980s, this concept began to become more and more popular. In the process of urban development, the environment will be damaged to a certain extent, and the sustainable development of the city is inevitable. Green building design can save resources and has become one of the hallmarks of modern cities. But green building is not widespread in China. Low-carbon life is very necessary, therefore, we should pay attention to the reasons why green building design has not been paid attention to and how to increase efforts to promote green building design. Green building should be the development direction of current construction industry. Adhering to the concept of ecology, energy conservation and sustainable development, green buildings will bring great changes to China's urban development. The development of green architecture in our country is still in its infancy, the green building design has failed to scale to thousands, its purpose is to promote people highly harmonious and unified, architecture, natural, economic and environmental benefits, social benefits fully coordinated, prompting the harmonious development of national economy and social environment, ecological environment quickly and well.

Low-Carbon Manufacturing or Not? Equilibrium Decisions for Capital-Constrained News Vendors with Subsidy and Carbon Tax

At a time when low-carbon life has become an important global issue, the decarbonization of manufacturing enterprises cannot be delayed in the face of the government’s green policy and other objective conditions. Under these circumstances, how to arrange the production plan before and after the implication of low-carbon policies is an urgent issue to be settled, especially for the capital-constrained news vendors. To address these problems, this paper firstly builds a stylized supply chain model consisting of two different types of manufacturers (i.e., low-carbon type and traditional type) with capital constraints, then obtains equilibrium production and business strategies resorting to Stackelberg game theory, and lastly conducts an analysis of how the key factors affect manufacturers’ green transition decisions under different scenarios of carbon policy. With the study’s structure, some interesting and important results and managerial insights are derived. For example, but not limited to, it is found that: (i) compared with traditional products, the price fluctuation of low-carbon products is greater than that of traditional products with the increase in consumers’ low-carbon awareness. And consumers have more tolerance for price increases for low-carbon products. (ii) When producing low-carbon products is cost-effective, it is a wise choice to produce more low-carbon products. When producing low-carbon items is costly, producing more low-carbon products is still a dominant strategy until the expenditure difference between low-carbon and traditional ones exceeds a certain threshold. (iii) When the expenditure on low-carbon production is moderate, the manufacturer first prefers the traditional strategy, then the low-carbon one, with an increase in consumers’ low-carbon awareness. When the expenditure on low-carbon production stays at a low or high level, the low-carbon strategy always dominates the traditional one with a certain condition satisfied. This study can enrich the theory of green supply chain management and provide decision support for enterprise managers in the green transition.

Population Structure and Local Carbon Emission Reduction: Evidence from Guangdong, China

Based on the data obtained on carbon emissions in Guangdong Province, China, from 1997 to 2019, this study focused on the relationship between energy consumption and population development in Guangdong Province. This study quantitatively analyzed the impact of different population structures and technological progress on carbon emissions in Guangdong Province by establishing an extended model of Stochastic Impacts by Regression on Population, Affluence, and Technology (STIRPAT). The results showed that the population size factor was not as good as the population structure factor for carbon emissions. In addition, different demographic factors affected carbon emissions differently with both positive and negative effects. Finally, relevant policy suggestions were proposed from the perspectives of encouraging the childbearing of appropriate-age residents, optimizing the population structure, reducing the separation of people and households, guiding residents to return to the traditional family model, guiding residents to live a low-carbon life, optimizing industrial institutions, and adjusting the energy consumption structure.

High-performance lithium-ion battery equalization strategy for energy storage system

Abstract In pursuit of low-carbon life, renewable energy is widely used, accelerating the development of lithium-ion batteries. Battery equalization is a crucial technology for lithium-ion batteries, and a simple and reliable voltage-equalization control strategy is widely used because the battery terminal voltage is very easy to obtain. But when the battery voltage is used to determine whether the battery needs to end equalization, it often does not reflect the state of charge well, resulting in battery management system misjudgment, which makes it unable to achieve a better equalization effect. In this paper, we propose a high-performance equalization control strategy based on the equalization data of the general equalization strategy, which turns on the equalization again after the equalization is completed and uses the equalization time instead of the battery voltage as the indicator. In this paper, we analyse and test this principle in detail. The difference between the final voltage of the equalized battery and the target voltage is only 4 versus 3 mV, which is an extreme advantage compared with the error of 18 versus 24 mV of the general equalization strategy, and it adds almost no workload, which makes it a good prospect for application.

Application Scenarios, Low-carbon Models and Practical Paths of Green Payments in China

As an infrastructure in the field of green finance, green payment plays an important role in guiding the green-oriented allocation of social resources and the public's awareness of environmental protection, and promoting the greening, recycling and low-carbonization of the production methods of enterprises and the consumption patterns of individuals and households. This paper explores the basis of green payment development in China from five aspects: theory, market, policy, finance and digital ecology, and examines the positioning of green payment to help achieve the goal of "carbon neutrality" at three levels: macro, meso and micro. In the light of the lifestyles of Chinese residents, the specific application scenarios of green payment in China, such as transportation, low-carbon life and paperless payment, are compiled. We use electronic payment methods such as WeChat payment to explore the mode of green payment ecosystem to achieve low-carbon development, and explore the practical path of green payment to help "carbon neutrality" in both broad and narrow sense from the perspective of industrial chain. Finally, the above analysis is combined with the practical significance of green payment for carbon neutrality and the suggestions for the future development of green payment in different dimensions.

Analysis on Site Selection of Electric Vehicle Charging Pile in Xi'an

Nowadays, China practices “low-carbon life”, and environmental protection is the general trend. As an emerging industry, new energy electric vehicles must solve the problem of charging pile shortage in order to maintain a good momentum of development, so as to occupy a certain market share in the automotive industry. Therefore, with limited resources, it is necessary to make the distribution of charging pile more reasonable. This paper takes Xi'an city as an example to predict the best location for charging pile construction by entropy TOPSIS method in order to improve the utilization rate of charging piles, which has reference significance for the construction of charging piles.

Research on low-carbon lifestyle of college students in Hubei University and promotion strategies

College students, as high-quality talents for China's future social construction, are the main force for practicing low-carbon life. Through investigating the cognition, willingness, behavior and motivation of low-carbon life among college students in Hubei universities, it is found that most college students do not have a sound low-carbon cognitive concept, and their awareness of responsibility for low carbon and the subjective motivation to spread it are not strong, so it is difficult to change their low-carbon behavior in the short term. Accordingly, countermeasures to promote low-carbon lifestyle of college students are proposed in terms of raising responsibility awareness, visualizing "low-carbon", creating a good campus low-carbon atmosphere, cultivating "low-carbon" models, and promoting low-carbon ideological innovation.

Multi-dimensional and Comprehensive Measurement Study on Low-carbon Development of China's Megaciti

Taking China's megacities as the research unit, this paper selected 18 indexes from five dimensions: low-carbon economy, low-carbon development, low-carbon life, low-carbon environment and low-carbon energy consumption, and constructed a low-carbon development evaluation system. Combined with data envelopment analysis, a multi-dimensional and comprehensive measurement evaluation of the low-carbon development level of China's megacities was also conducted. The results showed that: (1) The average comprehensive scores of 16 Chinese megacities in 2005, 2010 and 2015 were 0. 0892, 0. 0854 and 0. 863, respectively. The low carbon development level showed a trend of first decreasing and then rising. (2) Spatially, the low-carbon development level of eastern cities was generally high, but the internal differences were large, and the development of the Beijing-Tianjin-Hebei region was uneven, with Beijing having a higher level of development and Tianjin having a lower level of development. The development index of the western region was generally low, and the scores of Chongqing, Chengdu and Xi'an were all at low and lower levels. (3) From 2005 to 2015, the development of low-carbon economy increased steadily, of which the development level of the eastern region was significantly improved. The level of low-carbon development had declined. The level of low-carbon living was showing a significant downward trend. The development of a low-carbon environment had improved. The development of low-carbon energy consumption was basically stable, but the pattern had changed slightly. (4) From 2005 to 2015, the overall level of the comprehensive performance of national low-carbon development was not high, which reached 75. 3% of the optimal level, and there was a problem of low input-output efficiency. The pure technical efficiency of low-carbon development had only reached 88. 3% of the optimal level, which had great development potential. The scale efficiency of low-carbon development had reached 90% of the optimal level, and there was room for improvement.

Design of Lightning Current Monitoring System on Wind Turbines

In recent years, because climate change is a major issue related to human survival and sustainable development, the global climate is warming and glaciers are melting, so the country has been advocating “green environmental protection, low-carbon life”. To achieve this goal, China is constantly looking for green and sustainable energy. However, in thunderstorm weather, wind turbines are more likely to be attacked by lightning. Even if we have a set of strict technology for lightning protection of wind turbines, we cannot resist direct lightning strikes. The blade of a wind turbine is the first target of lightning strikes. Therefore, this paper designs a lightning current monitoring system for wind turbines based on Rogowski coils, and designs a current measurement system that can be stably used to monitor the whole process of discharge when wind turbines are struck by lightning, so as to improve the safety of wind turbines. To improve the wind power generation technology due to the economic losses caused by lightning strikes to wind power generation enterprises.

Research on the Influencing Factors of Carbon Emissions in Anhui Province based on LMDI Model and STIRPAT Model

Based on the improved model of Kaya identity and LMDI decomposition method, this paper conducts decomposition analysis on the influencing factors of carbon emissions in Anhui Province from 2008 to 2020. Based on the results of LMDI decomposition method, this paper uses STIRPAT model to conduct regression analysis to study the internal driving factors of carbon emissions in Anhui Province, and provides targeted carbon emission reduction suggestions. The results show that economic development contributes the most to the positive pull of carbon emissions, and energy intensity contributes the most to the inhibition of carbon emissions. Optimizing the energy structure, improving the energy utilization rate, optimizing the industrial structure, developing the economy with high quality, and improving residents' awareness of low-carbon life can all inhibit CO2 emissions.

The Impact of the Gain-Loss Frame on College Students' Willingness to Participate in the Individual Low-Carbon Behavior Rewarding System (ILBRS): The Mediating Role of Environmental Risk Perception.

Since Chinese households account for more than half of the country’s total carbon emissions, efforts focused on consumption will be key to reaching carbon reduction targets. The Individual Low-carbon Behavior Rewarding System (ILBRS) is an emerging mechanism in China that encourages the public to develop a low-carbon lifestyle and it is critical to look for various approaches to enhance the public’s willingness to participate in it. The framing effect has been widely used to study pro-environmental behavior as a low-cost nudge. We used an online questionnaire (N = 320) to investigate how framing information (loss and gain framing) influenced people’s willingness to participate in the ILBRS through the mediation of environmental risk perception. The results indicated that the public’s willingness to participate in the ILBRS under the loss frame was significantly higher than the gain frame. Furthermore, environmental risk perception played a mediating role in the proceedings. Based on our findings, the designers and promoters of ILBRS systems could employ loss-frame information to promote the public’s willingness to participate in the ILBRS and drive more people to live a low-carbon life in the process of mechanism construction, information communication, and operational promotion.

Public Awareness, Lifestyle and Low-Carbon City Transformation in China: A Systematic Literature Review

Low-carbon city transformation is an important action area of China’s 14th Five-Year Plan (2021–2025) that aims to reach peak CO2 emissions by 2030 and achieve carbon neutrality before 2060. Responding to global climate change is not only a national responsibility but also an individual responsibility and very much depends on societal participation and acceptance. While many scholars argue that public participation would be critical to low-carbon cities developing in China, there is apparently a lack of sufficient research on the level of public participation. This systematic review aims to summarize the current related research about public awareness on low-carbon city transformation in China, and learn about the challenges and barriers of public attitude and behaviour towards the low-carbon lifestyle. This study reveals that: (1) although most scholars discussed the conception and policies of low-carbon cities, research methods, the theoretical foundation and the number of cities targeted for research are limited; (2) a public’s attention to low-carbon cities mainly focus on a low-carbon life, and there is a clear gap between low-carbon awareness and behaviour; and (3) although scholars had different opinions about the factors that affect low-carbon behaviour, most of them agree that education and government policy have an influence on the populations’ low-carbon behaviour in China.

Layer-by-layer stacking, low-temperature welding strategy to effectively recycle biaxially-oriented polypropylene film waste

High-value recycling and reuse of plastic products is very important to solve global plastic pollution in the era of green development and low-carbon economy. Giving that the mainstream of processing plastic waste is still direct mechanical recycling, the unexpected degradation on mechanical properties betrays the intention to recycle plastic waste. Here, based on the temperature sensitivity of interfacial diffusion and orientation retention, we proposed an innovative protocol of recycling biaxially oriented polypropylene (BOPP) film waste in high value and efficient manner. Specially, a lamellar assembly of the biaxially-oriented film wastes was constructed layer by layer and then compressed into a sheet near the melting temperature. The temperature effects on interfacial fusion and orientation retention were investigated comprehensively. When the welding temperature approached the end melting temperature, the low-temperature laminated processing technology not only enabled strong interfacial adhesion, but also retained most of intrinsic orientation structure, conferring the as-prepared sheet with unprecedented combination of strength and toughness, as evidenced by a dramatic increase in ∼200% of mechanical strength and ∼650% of toughness to that of mechanically-recycled convention polypropylene (PP) products without orientation. The enhancement mechanism, in essence, stemmed from high strength endowed with orientation order and the laminar structure with strong ability to inhibit the crack propagation. Finally, supercritical CO 2 foaming technology was utilized to transform the high-performance fused PP sample into more valuable lightweight and rigid foam. This simple, scalable, economical and highly effective method without any interfacial additives is easily applied to the other biaxially-oriented films and sets a good example for the recycling application of biaxially-oriented film wastes to achieve the goal of green and low-carbon life. • The strategy of low-temperature welding with orientation retention method was firstly proposed. • Orientation structure endowed the high strength of welded samples accompanying the substantial ductility and toughness. • A lightweight foam with high-strength and excellent thermal insulation was prepared based on the welded samples. • This strategy is scalable and universal for biaxially-oriented films.
