Despite the economic benefits of remittances, there is rising concern about their impact on environmental degradation. The NARDL approach was used to analyze time-series data from 1980 to 2018, to determine the impact of remittances increases and decreases on environmental degradation in Nigeria. The cointegration results show that remittances and environmental degradation have a long-run relationship. The study found that remittances is asymmetrically connected to ecological footprint (EFP) as a measure of environmental degradation both in the long run and short run whereas it is asymmetrically connected with CO2 as a measure of environmental degradation in the long run only. The study also found that remittances increase contributes to environmental degradation in Nigeria in the long run.","PeriodicalId":43051,"journal":{"name":"Chinese Journal of Urban and Environmental Studies","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2022-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44134226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the impact of climate change on dysentery is being studied in specific areas, a study in Iran is lacking. In this study, RCP 4.5 and RCP 8.5 scenarios were used to predict the prevalence of dysentery in Iran between 2050 and 2070. This study is a secondary analysis using Geographically Weighted Regression, and 273 cities of Iran were analyzed between March 2011 and March 2017. Bioclimate variables were used as independent variables. Ecological data about the prevalence and incidence of dysentery, which were collected between 2011 and 2017, were used as the dependent variables. The result shows the incidence of dysentery is significantly associated with bioclimate change exposure, in 2050 and 2070, based on RCP 4.5 and RCP 8.5. Our findings showed that in the absence of adaptation of the population, an increase in the risk of bioclimate-related diseases is expected by around 95.6% in the mid-century compared with the beginning of the century with regional variations. Based on these findings, the geographical distribution of the disease will also change. In 2050, the pattern of disease distribution would be changed, and the north of Iran will be included in the vulnerable regions. In 2070, the southeastern and northern parts of Iran will have the most vulnerability to climate change. Our study contributes important knowledge to this perspective by providing insightful findings and pieces of evidence for climate change adaptation and mitigation.","PeriodicalId":43051,"journal":{"name":"Chinese Journal of Urban and Environmental Studies","volume":"1 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2022-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41543491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, this study investigates the relation of tourism, natural resources, globalization, and foreign direct investment on the ecological footprint of the USA, the UK, Pakistan, China, and India by using annual data from 1995 to 2020. The study applied Zivot and Andrews (1992) test to demonstrate the stationarity properties of the series, and an autoregressive distributed lag (ARDL) approach was employed to estimate the long-run and short-run dynamics. The long-run findings disclose that tourism has a significantly positive effect on China and Pakistan, but a significantly negative impact on India. The outcomes further suggest that foreign direct investment increases environmental degradation in India and China in both long and short periods, but contributes to improving the UK’s ecosystem. Besides, globalization in China tends to save its environment. Natural resources in the long run also harm the ecosystems of Pakistan, China, and the USA. The error correction term is negatively significant for all countries. The reliability of the model is investigated through diagnostic tests. The selected model is stable as the critical value of CUSUM and CUSUMSQ lie within the 5% significance level.","PeriodicalId":43051,"journal":{"name":"Chinese Journal of Urban and Environmental Studies","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2022-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46756933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The year 2021 is the first year of China’s 14th Five-Year Plan period. As the main battlefields to achieve the “dual carbon” goals, cities are also required to build on their pathways towards such goals under new conditions. Based on the progress China has made with pilot cities for low-carbon development and the discussion on 60 cities by category, this paper identifies the commonalities and differences between Chinese cities’ pathways towards carbon peaking, and concludes that Chinese cities need to peak their carbon emissions in an organized and step-wise way on the basis of classification and according to their own development level and emission characteristics. In light of the above conclusion, this paper provides feasible suggestions for Chinese cities’ carbon peaking.","PeriodicalId":43051,"journal":{"name":"Chinese Journal of Urban and Environmental Studies","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49156657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

China needs to work on many aspects, including transport restructuring, alternative fuel technologies and energy efficiency improvement, to achieve near-zero emission goals by 2060.

In recent years, the country’s direct carbon emissions in the building sector have hit a plateau while the total emissions still grow rapidly. Besides, the building materials for construction and refrigerants leaked during buildings’ operation also result in greenhouse gas emissions. To achieve the targets set for future low-carbon development, the building sector should feature “sufficient demand, decarbonized structure and flexible load.” According to the analysis of the emission reduction approaches adopted by different sectors, China’s building sector should make a ceaseless effort to promote building energy conservation, improve electrification, and load flexibility, reform the energy system in rural areas, optimize the heating structure in northern China’s urban areas, as well as reduce the emissions during construction and the non-CO2 gas emissions. In the 14th Five-Year period, it is suggested to clarify the total energy consumption and carbon emission targets, adjust the energy structure more vigorously, and draw up more measures to reduce the emissions related to construction and refrigerant leakage.","PeriodicalId":43051,"journal":{"name":"Chinese Journal of Urban and Environmental Studies","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45951197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this industry will play an important role in achieving the carbon peaking and carbon neutrality goals (“dual carbon” goals) for the whole society. For this purpose, it is critical to balance four relationships, i.e. relationship between carbon mitigation and energy security, carbon peaking in the short term and carbon neutrality in the long term, the coordinated carbon mitigation in power industry and other industries, and technical feasibility and economic efficiency. This paper proposes the China’s Energy Interconnection scenario to promote carbon peaking and carbon neutrality of the society, which can be divided into three stages, i.e. peaking carbon emissions before 2030, rapid emission reduction during 2030–2050, and comprehensive carbon neutrality before 2060. It is expected that the power system will achieve zero emissions before other industries and contribute negative emissions afterwards, providing emission space for carbon neutrality in other industries across the society. Looking into the future, China’s electricity demand will continue to grow. Clean energy will become the main power source, the use of coal-fired power will be gradually reduced, and gas-fired power will undertake the function of peak-load regulation. Faster progress will be made in forming an overall grid pattern with ultra-high voltage (UHV) grid as the backbone and featuring “west-to-east and north-to-south power transmission, a balanced energy mix, and transnational power interconnection.” Finally, this paper discusses a new-type of power system characterized by a high proportion of electricity generated from clean energy, high ratio of electric and electronic equipment, and a high proportion of power transmission and reception, together with summer and winter high load periods, and points out the challenges faced by the new-type power system with a high proportion of renewable energy sources in terms of flexibility, safety, and economic efficiency, and proposes corresponding policy recommendations.","PeriodicalId":43051,"journal":{"name":"Chinese Journal of Urban and Environmental Studies","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2022-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43772979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As China pledges to achieve carbon peaking and carbon neutrality goals, how to keep a balance between carbon emission reduction and coal consumption has become a serious problem and daunting challenge facing the industrial chain of coal-based energy for a long time. The prospects for the coal mining industry are increasingly limited under carbon constraints. Faced with serious challenges in its positioning and technological development, the coal-fired power industry is suffering the consequences of negative environmental externalities. Therefore, the low-carbon transformation of China’s coal-based energy industry is necessary and urgent. This paper conducts an in-depth analysis of the development status of China’s coal-based energy industry under the carbon peaking and carbon neutrality goals and the obstacles in the transformation and upgrade of the coal-based energy industry, and comes up with response strategies. The future coal-based energy industry should make full use of emerging low-carbon clean technologies such as carbon capture, utilization, and storage to achieve low-carbon transformation, and upgrade of the entire industrial chain, following the current development trends.","PeriodicalId":43051,"journal":{"name":"Chinese Journal of Urban and Environmental Studies","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2022-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42699984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
