There is a lack of proper research that highlights the impact of institutional quality (IQ) and renewable energy consumption (REC) on the carbon emission (CE). The significance of IQ and REC in the achievement of zero CE is highlighted in this research. The current research reports the effects of these important factors on the consumption-based carbon emissions in the G-7 countries from 1995 to 2018. Based on the outcome of the cointegration test, the long-run connection is recognized between IQ, REC, GDP, exports, imports, and consumption-based CE. The findings also validated that there exist significant decrease and increase in the CE in both the short and long run; for instance, IQ, REC, and exports decrease the CE, while imports and GDP increase the CE. The estimates of causality test showed that policies aimed at improving IQ, REC, GDP, exports, and imports have a significant impact on the CE. Consequently, based on these results, policymakers in the G-7 must prioritize IQ and REC to enhance environmental quality and attain carbon neutrality.
目前缺乏适当的研究来强调制度质量（IQ）和可再生能源消费（REC）对碳排放（CE）的影响。本研究强调了 IQ 和 REC 在实现零 CE 方面的重要性。本研究报告了这些重要因素对 1995 年至 2018 年 G7 国家基于消费的碳排放的影响。基于协整检验的结果，确认了 IQ、REC、GDP、出口、进口和基于消费的 CE 之间存在长期联系。研究结果还表明，CE 在短期和长期都存在显著下降和上升，例如 IQ、REC 和出口减少 CE，而进口和 GDP 增加 CE。因果关系检验的估计表明，旨在提高 IQ、REC、GDP、出口和进口的政策对 CE 有重大影响。因此，根据这些结果，G7 国家的政策制定者必须优先考虑 IQ 和 REC，以提高环境质量并实现碳中和。
