Irrespective of the vast array of empirical evaluations pertaining to the environmental Kuznets curve (EKC) hypothesis, both for India and other countries, previous studies, amid divergent submissions, inadvertently failed to highlight the relevant threshold that ensures significant reductions in environmental decay. Additionally, the implications of environmental-control technology on environmental quality are also lacking mostly in the context of Indian economy. Thus, this study enlists environmental-control technology and other relevant factors over the period 1980–2018 and employs the novel multiple threshold nonlinear ARDL technique, a model rarely applied in previous studies for updated empirical narratives. Accordingly, the empirical evidence rectifies that the variables converged to long-run equilibrium. Furthermore, from the tercile partial deviations, it is established that at the middle threshold (GDP²_W2), pollution shrinks more significantly amid rising income, thereby validating the EKC hypothesis for India. Likewise, environmental-control technologies provided only a short-term insignificant carbon neutrality pathway, whereas they provided long-term insignificant emission increasing effects. This implies that the depth of such technology in India is inadequate to invoke cleaner environments at all times. Likewise, energy consumption and urbanization processes are significant environmental polluters, while trade openness provides insignificant long- and short-term carbon emission effects. Against this background, economic growth within the middle threshold promises a more sustainable environment amid rising national income at all times. Moreover, given its short-term outcomes, strengthening the depth of environmental-control technology is imperative to ensure a long-lasting clean environment in India.

尽管针对印度和其他国家/地区的环境库兹涅茨曲线 (EKC) 假设进行了大量实证评估，但之前的研究在意见分歧的情况下无意中未能强调确保显着减少环境衰退的相关阈值。此外，在印度经济背景下，环境控制技术对环境质量的影响也很缺乏。因此，本研究纳入了 1980-2018 年期间的环境控制技术和其他相关因素，并采用了新颖的多阈值非线性 ARDL 技术，该模型在以前的研究中很少用于更新实证叙述。因此，经验证据表明变量收敛于长期均衡。此外，² _W2)，污染在收入增加的情况下更显着减少，从而验证了印度的 EKC 假设。同样，环境控制技术只提供了一个短期的微不足道的碳中和途径，而它们提供了长期微不足道的排放增加效应。这意味着印度此类技术的深度不足以始终唤起更清洁的环境。同样，能源消耗和城市化进程是重要的环境污染源，而贸易开放对碳排放的长期和短期影响微不足道。在此背景下，中等门槛的经济增长有望在国民收入不断增加的情况下实现更可持续的环境。此外，鉴于其短期成果，
