In Modern era, the Researchers are keenly interested in different areas of green financing projects such as green economics, green trade, green sustainable development activities, green climatic and environment quests, green investment and financial ventures, and green public policy-related topics, respectively. Owing to the lower cost of production for sustainable development, a healthy climate, and a neat environment is needed, this study is structured to build the significant relationship between various green sustainable development projects, the financial effectiveness and performance of PSX and NYSX, respectively. For this purpose, the time series data for 2000–2020 are collected from IFS, WBI, SBP, the Federal Reserve system, S&DP, and the UNDP financial reports. The empirical analysis reveals the insignificant effects of green investment, financial projects, public policies, and social green projects on the financial performance of PSX, whereas the empirical modeling also attests that all the green factors significantly affect the performance of NYSX except the green economic and trading projects and renewable energy green projects, which are insignificant predictors with respect to FIP-NYSX. Moreover, the index for human development insignificantly affects the prediction of FIP-NYSX. The mixed empirical results guide policymakers, the board of PSX and NYSX, and the management of green financing companies to reconsider their policies and objectives with respect to successful green operations and the financial performance of PSX and NYSX.
