After the UN Climate Action Summit in 2019, many countries started progressing towards race to zero targets. The intricate framework of digitalization and green technologies has the potential to persuade governments to implement policies that promote a zero-carbon economy, i.e., green economy. Hence, this study determines the effect of digital trade (DGT) and green technological innovation (GTI) on environmental sustainability (ENS) by considering the role of renewable energy consumption (REC), globalization (GLOB), and economic growth (EG). The study measured ENS by taking into account three proxy variables, i.e., ecological footprint (EF), carbon dioxide emission (COe), and methane emissions (CHe). POLS and PMG-ARDL techniques are applied to the panel data of BRICS (Brazil, Russia, India, China, and South Africa) from 2000 to 2019. Panel Quantile Regression (PQR) along with AMG and CCEMG estimators is applied hereafter for checking the robustness of the empirical results. The long-run empirical outcomes show the positive association of DGT, GTI, REC, and GLOB with ENS. Lastly, this study inscribed the Environmental Kuznets Curve (EKC) and highlights policy implications and governmental measures to ensure environmental sustainability in BRICS economies.
在 2019 年联合国气候行动峰会之后，许多国家开始朝着零目标竞赛迈进。数字化和绿色技术的复杂框架有可能说服政府实施促进零碳经济（即绿色经济）的政策。因此，本研究通过考虑可再生能源消费（REC）、全球化（GLOB）和经济增长（EG）的作用，确定了数字贸易（DGT）和绿色技术创新（GTI）对环境可持续性（ENS）的影响。本研究通过考虑三个代理变量，即生态足迹（EF）、二氧化碳排放（COe）和甲烷排放（CHe），来衡量 ENS。采用 POLS 和 PMG-ARDL 技术对 2000 年至 2019 年期间金砖国家（巴西、俄罗斯、印度、中国和南非）的面板数据进行了分析。此后，应用面板分位数回归（PQR）以及 AMG 和 CCEMG 估计量来检验实证结果的稳健性。长期实证结果表明，DGT、GTI、REC 和 GLOB 与 ENS 呈正相关。最后，本研究记录了环境库兹涅茨曲线（EKC），并强调了政策含义和政府措施，以确保金砖国家经济体的环境可持续性。
