This study investigates the association between remittances, FDI, energy use, and CO₂ emissions for a sample of the top six Asian nations receiving remittances, namely, China, India, the Philippines, Pakistan, Bangladesh, and Sri Lanka, during the 1982–2014 period. The results of employing an autoregressive distributed lag (ARDL)-bound technique signify that there is a stable long-run association among the stated variables. The empirical findings indicate that CO₂ increases significantly with a rise in energy use in all sample nations in both the long and short-runs. Conversely, the association between CO₂ emissions and remittances is found to be significantly positive for Sri Lanka, Pakistan, the Philippines, and Bangladesh in the long-run, positive for Pakistan, the Philippines, and Sri Lanka only in the short-term, and non-significant for India and China in both the long and short-runs. Furthermore, the empirical results illustrate that the inflow of FDI significantly increases CO₂ emissions in the cases of China, Sri Lanka, and India in both the long and short-runs. While FDI inflow has no significant effect on CO₂ emissions for the Philippines and Pakistan, it has a significant negative effect for Bangladesh in both the long and short-runs. Thus, the connection between remittances, FDI, and CO₂ emissions varies significantly across the countries considered in our study.
