Abstract

The electricity sector is the biggest emitter of greenhouse gases in Bangladesh, and the country has the target to reduce these emissions and follow an environmentally sustainable development strategy. In this study, we explore how population growth, affluence and energy technology factors affect the emissions of carbon dioxide, methane and nitrous oxide emissions from the electricity sector in Bangladesh. This study employs an extended stochastic impacts by regression on population, affluence and technology model, using ridge regression for the analysis, covering a period from 1995 to 2014. The study also examines the presence of the environmental Kuznets curve (EKC) with respect to greenhouse gas emissions. We find that the chief drivers of carbon dioxide, methane and nitrous oxide emissions are population, affluence, urbanization and the carbon intensity of fuels. Energy intensity affects carbon dioxide and methane emissions. Transmission losses do not have a significant positive influence on emissions of any of the gases except carbon dioxide. Our results also show that there is no evidence of the EKC with respect to greenhouse gases in the electricity sector. Our study suggests that Bangladesh should have policies promoting a cleaner energy mix, reduce the use of fossil fuels, and increase energy efficiency technologies to counter the polluting effects of a growing power sector.

孟加拉国电力部门中温室气体排放的驱动因素

摘要

电力部门是孟加拉国最大的温室气体排放国,该国的目标是减少这些排放并遵循环境可持续发展战略。在这项研究中,我们探讨了人口增长,富裕程度和能源技术因素如何影响孟加拉国电力部门的二氧化碳,甲烷和一氧化二氮排放。这项研究通过对人口,富裕程度和技术模型进行回归分析,采用了扩展的随机影响,并使用岭回归进行了分析(涵盖1995年至2014年)。该研究还研究了温室环境Kuznets曲线(EKC)的存在气体排放。我们发现二氧化碳,甲烷和一氧化二氮排放的主要驱动因素是人口,富裕程度,城市化和燃料的碳强度。能源强度会影响二氧化碳和甲烷的排放。传输损耗对除二氧化碳以外的任何气体的排放都没有明显的积极影响。我们的结果还表明,在电力部门中,没有关于温室气体的EKC证据。我们的研究表明,孟加拉国应制定政策,促进更清洁的能源结构,减少化石燃料的使用,并提高能效技术,以应对不断增长的电力部门的污染影响。我们的结果还表明,在电力部门中,没有关于温室气体的EKC证据。我们的研究表明,孟加拉国应制定政策,促进更清洁的能源结构,减少化石燃料的使用,并提高能效技术,以应对不断增长的电力部门的污染影响。我们的结果还表明,在电力部门中,没有关于温室气体的EKC证据。我们的研究表明,孟加拉国应制定政策,促进更清洁的能源结构,减少化石燃料的使用,并提高能效技术,以应对不断增长的电力部门的污染影响。
