The research led to the development of novel cross-panel data (CPD) approaches, whereby the regressand of a single nation relies concurrently on regressor from a wide variety of other countries. This research developed the Augmented CrossPanel (ACP) unit root test and the Cross-Panel ARDL (CPARDL) estimator. It used them to measure Pakistan's environmental quality, which is sensitive to the choices made by other nations in the South Asian region. The information ranges from 1990 to 2021. The CPARDL estimates demonstrate that Pakistan's carbon emissions are mitigated by the increased contribution of India's alternative energy sources and Afghanistan's economic development. The political unrest in Bangladesh negatively impacted Pakistan's ecological stability. The CPD approach evaluates multi-regional projects to ensure sustainable infrastructure development
