In an exploration of environmental concerns, this groundbreaking research delves into the relationship between GDP per capita, coal rents, forest rents, mineral rents, oil rents, natural gas rents, fossil fuels, renewables, environmental tax and environment-related technologies on CO emissions in 30 highly emitting countries from 1995 to 2021 using instrumental-variables regression Two-Stage least squares (IV-2SLS) regression and two-step system generalized method of moments (GMM) estimates. Our results indicate a significant positive relationship between economic growth and CO emissions across all quantiles, showcasing an EKC with diminishing marginal effects. Coal rents exhibit a statistically significant negative relationship with emissions, particularly in higher quantiles, and mineral rents show a negative association with CO emissions in lower and middle quantiles, reinforcing the idea of resource management in emissions reduction. Fossil fuels exert a considerable adverse impact on emissions, with a rising effect in progressive quantiles. Conversely, renewable energy significantly curtails CO emissions, with higher impacts in lower quantiles. Environmental tax also mitigates CO emissions. Environment-related technologies play a pivotal role in emission reduction, particularly in lower and middle quantiles, emphasizing the need for innovative solutions. These findings provide valuable insights for policymakers, highlighting the importance of tailoring interventions to different emission levels and leveraging diverse strategies for sustainable development.
在探索环境问题时,这项开创性的研究深入探讨了人均 GDP、煤炭租金、森林租金、矿产租金、石油租金、天然气租金、化石燃料、可再生能源、环境税和与环境相关的技术对 1995 年至 2021 年 30 个高排放国家的二氧化碳排放的影响。研究使用工具变量回归两阶段最小二乘法(IV-2SLS)回归和两步系统广义矩估计(GMM)估计。我们的结果表明,经济增长与所有分位数的二氧化碳排放之间存在显著的正相关关系,展示了具有递减边际效应的 EKC。煤炭租金与排放量呈显著负相关,特别是在较高分位数,矿产租金与较低和中等分位数的二氧化碳排放呈负相关,这加强了在减排中进行资源管理的理念。化石燃料对排放有相当大的不利影响,在递增分位数中影响越来越大。相反,可再生能源显著减少了二氧化碳排放,在较低分位数的影响更大。环境税也减轻了二氧化碳排放。与环境相关的技术在减排方面发挥着关键作用,特别是在较低和中等分位数,这强调了需要创新解决方案。这些发现为政策制定者提供了有价值的见解,强调了根据不同的排放水平调整干预措施和利用多样化的可持续发展战略的重要性。
