It has drastically changed, and exacerbated Electricity has always been thought of as a traditional production factor. Energy is required not only for production but also for long-term economic growth, which can only be achieved with a consistent energy supply. Although renewable energy is essential to protect the future climate, electricity is regarded as the backbone of economic progress and well-being. Thus, in Pakistan, environmental pollution significantly increased due to the discharge higher concentration of carbon dioxide emissions. It has a multifaceted effect on pollution emissions. Thus, this research investigates the nonlinear and linear connection between RE and 𝐶𝐶2emissions over 1980-2020 in Pakistan. For the empirical estimation this research 1st used Augmented Dickey fuller (ADF), and Phillips Perron (pp) unit root tests to inspect the level of integration. After the confirmation of integration order ahead to inspect the symmetric and asymmetric short and long-run elasticities of coefficients, ARDL and nonlinear ARDL econometric technique is employed. The ADF and PP unit tests indicate mixed order of integration i.e.,𝐶𝐶2, and UR are integrated as I (1) and rest of variables integration order is I (0). After the confirmation of integration order, we used symmetric and asymmetric ARDL. Besides, the empirical findings from symmetric ARDL depicts that increases in the level of RE meaningfully decline in𝐶𝐶2 in the long run. The results also show that GDP statistically significantly stimulate the 𝐶𝐶2 Ems in the long run in Pakistan. According to the nonlinear ARDL estimation technique that partial sum of positive changes in RE are negatively connected with carbon emissions both in the short and long run. On the other hand, partial sum of negative change in RE are positively connected with 𝐶𝐶2 Ems in the short and long run. Further, coefficient of HD considerably declines in 𝐶𝐶2 Ems in the long run. However, GDP and UR are positively connected with carbon emissions in the long run. Further, the result suggests that TO considerably improve the environmental performance in Pakistan. Moreover, the finding assumed that the positive part of RE infers a more significant effect than the negative part. Study results show that an eco-friendly consumption pattern may promote. The insertion of greener 5 forms of energy in urban dwellers must be enhanced, which would help combat the upsurge in industrial and housing carbon dioxide emissions.en-USThesis
