Abstract

Globally, the issues of climate change and global warming rapidly rises due to extensive CO emission. In this regard, countries across the globe initiate policies to combat CO emissions and attain a carbon neutrality target. As an emerging research area, the current study investigated carbon neutrality targets for BRICS economies (excluding Russia) covering the period from 1980 to 2018. This study covers important variables that influence both the economy and energy. Considering the role of electricity production from renewable energy and globalization, this study also checked for the role of income and renewable energy consumption. Various second-generation unit root and cointegration tests are used for the panel data to observe the stationarity and long-run relationship among these variables. Also, the DOLS and FMOLS are employed for the long-run estimation. Additionally, the article utilizes fixed effect and random effect models. This study also utilizes the augmented mean group (AMG) to confirm the prior findings. The empirical findings present evidence of the validity of the environmental Kuznets curve (EKC) hypothesis in the region. Moreover, the findings suggest that income and globalization play a positive role in carbon dioxide emission, which negatively influences the carbon neutrality target. However, electricity production from renewable energy and renewable energy consumption is efficient for achieving carbon neutrality targets. Specifically, the AMG estimates reveal that a percent increase in GDP and globalization increases 1.087 and 0.0342 % CO emissions while a unit increase in renewable electricity production and renewable energy consumption declines CO emissions by 0.0205 and 0.0143 %, respectively. The results are found robust and significant. Based on the empirical findings, policy implications are provided that would lead the BRICS region to attain the carbon neutrality target by revising the policies concerning globalization and economic growth. Also, proper attention should be paid to renewable energy electricity adaptation.

摘要

全球范围内,由于 CO 排放广泛,气候变化和全球变暖问题迅速加剧。在这方面,全球各国都制定了政策来应对 CO 排放,以实现碳中和目标。作为一个新兴的研究领域,本研究调查了金砖国家经济体(不包括俄罗斯)的碳中和目标,涵盖了 1980 年至 2018 年的时期。本研究涵盖了影响经济和能源的重要变量。考虑到可再生能源发电和全球化的作用,本研究还检查了收入和可再生能源消费的作用。各种第二代单位根和协整检验用于面板数据,以观察这些变量之间的平稳性和长期关系。此外,还使用 DOLS 和 FMOLS 进行长期估计。此外,本文还使用固定效应和随机效应模型。本文还利用扩充均值组 (AMG) 来确认先前的发现。实证结果为该地区环境库兹涅茨曲线 (EKC) 假说的有效性提供了证据。此外,研究结果表明,收入和全球化在二氧化碳排放方面发挥了积极作用,这对碳中和目标产生了负面影响。然而,可再生能源发电和可再生能源消费对于实现碳中和目标是有效的。具体而言,AMG 估计表明,GDP 和全球化的百分之一增长分别增加了 1.087%和 0.0342%的 CO 排放量,而可再生电力生产和可再生能源消费的单位增加分别减少了 0.0205%和 0.0143%的 CO 排放量。结果是稳健且显著的。根据实证结果,提出了政策建议,这将使金砖国家地区通过修订有关全球化和经济增长的政策,实现碳中和目标。此外,应适当关注可再生能源电力适应。
