Table 2 exhibits the descriptive statistics of the variables. The sustainable development index (SDI) is measured as an index number which shows the means value of SDI is 0.51. the maximum SDI is 0.79 and minimum values is 0.10. TNR is gaged as percentage in GDP. The mean value of TNR is 23.23%. The maximum % of TNR is GDP is 65.32% and minimum values is 1.79%. The renewable energy consumption and nonrenewable energy consumption are taken in exajoule. The mean values of REC and NREC are 0.08 and 3.06 exajoule respectively while the maximum value of REC is 0.14 and NREC is 12.01 and minimum value of REC is 0.04 and NREC is 0.40 exajoule. TR is gaged as percentage of GDP. The mean value of TR is 76.40% and the maximum Trade value is 172.80 and minimum value of Trade is 29.87%. The standard deviation shows the fluctuation in data which shows the Trade has more variation than other variables.

The CD test results are revealed in Table 3, which confirm the presence of the CD in our data set. The CD test's alternative hypothesis is cross-sectional dependence, which our analysis accepts. This implies that CD exists in our data set. This implies that SDI TNR, REC, TR and NREC have a problem of cross-sectional dependency.

According to the existence of CD in the data, it is recommended that the stationarity of indicators and long-run association be checked utilizing the second-generation test for both unit root and cointegration. Table 4 shows that SDI is free from the problem of unit root at level according to both the CADF and CIPS tests, while other variables are integrated at first difference I (1). According to Table 5, a statistically significant cointegration is observed at a 1% significance level between taken variables, including TNR REC, TR, NREC, and SDI. The results of CADF and CIPS suggested that the data have a unit root problem by which this study did not fulfill the assumption of least square, that data should not have problem of unit root. Hence, these results suggest that this study applies a test of cointegration to detect a long-run relationship among variables.

According to Table 5, a statistically significant cointegration is observed at a 1% significance level between many variables, including TNR, NREC, TR, REC, and SDI.

It is evident from Table 6 that Total natural resources rents have negative and significant impact on sustainable development. The results are similar with (Gyamfi et al., 2021; Zuo et al., 2021; Turan & Yanıkkaya, 2020; Kolstad & Wiig, 2009). Gyamfi et al. (2021) and Zuo et al. (2021) both found that natural resource rents contribute to environmental degradation, with Gyamfi et al. (2021) specifically highlighting the role of these rents in increasing pollution. Turan and Yanıkkaya (2020) further support this, showing that resource rents have a negative impact on public education and health expenditures, which are crucial for human capital formation. Kolstad and Wiig (2009) provides a potential explanation for these findings, suggesting that the resource curse is driven by patronage and rent-seeking behavior. These studies collectively suggest that TNR can hinder sustainable development by contributing to environmental degradation and undermining human capital formation.
Sustainable development is positively affected by REC. The results consistently support the positive effect of renewable sources of energy uses on sustainable development (Güney, 2019; Candra et al., 2023). Sustainable development is positively affected by renewable resources-based energy consumption (Güney, 2019). Zhe et al. (2021) further underscores the positive influence of renewable resources-based energy on financial development, while Candra et al. (2023) emphasizes the role of renewable energy in economic growth and greenhouse gas emissions reduction. These findings collectively suggest that increasing REC is crucial for sustainable development.
NREC has a positive and have significant impact on sustainable development. The results are in line with (Ohlan, 2016; Ivanovski et al., 2020; Adams et a., 2018; Mohammadi et al., 2023). Ohlan (2016) and Ivanovski et al. (2020) both found a positive long-run effect of NREC on GDP in non-OECD countries. Adams et al. (2018) further supported these findings, indicating that the utilization of non-renewable energy sources has a higher effect on fostering GDP. Mohammadi (2023) found that both REC and NREC have a favorable effect on economic growth. These studies collectively suggest that both types of energy consumption can contribute to GDP, with NREC having a more significant impact.
TR has a positive and significant impact on sustainable development. The results are in line with (Vandenberg, 2017; Dao, 2015). Vandenberg (2017) suggested that trade can have a positive impact on employment, which is a key component of sustainable development. However, Dao (2014) argued that trade openness can lead to higher GDP, which is often seen as a key driver of sustainable development. These studies highlight the need for a nuanced understanding of the association between TR and sustainable development.
The ECT shows the error correction term in the study which shows the dynamic stability of the model. A model's adjustment of coefficients indicates how much the model was adjusted in the previous period. The coefficient of the ECT is 0.2625, and it is statistically significant. This suggests that the model maintains its dynamic stability over time. According to the results of the study, the model of the study is stable.
