ABSTRACT

The evaluation of the contribution of consumption-based carbon (CBCO₂) emissions in greenhouse gas (GHG) emissions is crucially important for the design of sustainable environmental policies. Despite its importance, attention to the discussion of the role of environment-related technologies (ERT) in abating CBCO₂ emission is limited. The role of ERT and renewable energy in reducing carbon emissions is investigated in a panel of seven emerging economies during 1990–2016 in the ‘Environment Kuznets Curve (EKC)’ framework. Cross-sectional dependence test, CIPS unit root test, Westerlund co-integration, and cross-sectional augmented autoregressive distributive lag econometric techniques are employed to support the propositions. Findings suggest the supportive role of environment-related technologies in the presence of renewable energy in reducing carbon emissions. However, GDP growth is substantially worsening the environment. The findings indicate the need to increase investment in environment-related technologies by the E-7 economies for a sustainable reduction in CB CO₂ emissions.

摘要

评估基于消费的碳 (CBCO ₂ ) 排放在温室气体 (GHG) 排放中的贡献对于可持续环境政策的设计至关重要。尽管它很重要，但关注环境相关技术 (ERT) 在减少 CBCO _{2中的作用的讨论}排放是有限的。在“环境库兹涅茨曲线 (EKC)”框架中，由七个新兴经济体组成的小组在 1990-2016 年间研究了 ERT 和可再生能源在减少碳排放中的作用。横截面相关性检验、CIPS 单位根检验、Westerlund 协整和横截面增强自回归分布滞后计量经济学技术用于支持这些命题。研究结果表明，环境相关技术在可再生能源减少碳排放方面的支持作用。然而，国内生产总值的增长正在大大恶化环境。_{调查结果表明，为了可持续地减少 CB CO 2}排放，E-7 经济体需要增加对环境相关技术的投资。
