Abstract. This paper empirically examines the relationship among corruption, technological innovation and environmental quality in select south Asian countries such as Bangladesh, India, Pakistan and Sri Lanka during the period from 1990 to 2016. The study used Panel Fisher and Kao residual cointegration & Full Modified OLS and Dynamic OLS to analyze the long run relationship among the variables. The study found that both corruption and technological innovation has positive and significant effect on CO2 emission which is taken as environmental quality. Therefore, the policy makers should incorporate innovation into reduction of CO2 emission.

Keywords: corruption, innovation, environmental quality, panel study.
