This article explores the nexus between three measures of greenhouse gases (CO₂, N₂O and CH₄) with economic growth (GDP) and energy use for six South Asian countries (Pakistan, India, Nepal, Bangladesh, Sri-Lanka and Bhutan) by using panel ARDL approach from 1990 to 2017. The paper evaluates the three panel models of nitrous oxide (N₂O), carbon dioxide (CO₂) and methane (CH₄) and studies the relationships with energy use and GDP in the context of (Environmental Kuznets curve) EKC. This study shows non-linear relation of CO₂ with GDP as well as of N₂O with GDP hence proves the presence of EKC in long run. The analysis of the study shows the positive significant impact of CO₂ on GDP and energy use in long. In case of short run, the relationship of CO₂ with energy use is significant at 10% level. In case of methane model for long run, there is negative relationship between CH₄ and energy use however, there is positive significant impact between CH₄ and GDP. However, there has been negative relationship of N₂O with energy use and positive insignificant relationship with GDP.
