The main purpose of this research is to test the effect of financial development, real GDP, population, technology on dioxide carbon emissions as well the technology effect of financial development and environmental degradation in the Saudi Arabia (KSA) over the period 1970–2016 and the STIRPAT (Stochastic Impacts by Regression on Population, Affluence, and Technology) with an Autoregressive Distributed Lag (ARDL) model is used for the empirical inquest. These empirical findings by the Bounds cointegration tests show that the financial development and technology have a negative and significant impact on environmental degradation, firstly. Secondly, the technology effect of financial development (composite effect of technology and financial development) has an unfortunate effect on environmental mitigation. Finally, lower environmental mitigation is associated by a deepening in total population and affluence. Moreover, findings from the pairwise Granger causality test point that there is no causality running from both financial development and technology to the effect of technology among KSA. On the opposite, we looked at economic growth Granger, cause environmental quality. In addition, a unidirectional causality was seen running from environmental quality to financial development. The same, the relationship between affluence and financial development in KSA is unidirectional. Thus, various policy implications should be proposed to policymakers as enhancing the expansion of technology, especially in the industrial sector by incorporating renewable energy consumption to upgrade environmental quality.
