Various　old　nexuses　are　getting　new　empirical　attention　in　advanced　econometric.　Therefore,　we　examine　the　asymmetric　influence　of　remittances　and　FDI　on　CO2　emissions　by　using　the　NARDL　approach　for　China　from　1981　to　2019.　Based　on　NARDL　empirical　findings,　a　negative　change　in　remittances　has　also　positive　effects　on　CO2　emissions　in　the　short　and　long　run.　We　found　that　positive　and　negative　change　in　FDI　has　also　a　positive　effect　on　CO2　emissions,　while　a　positive　change　in　FDI　is　relatively　more　effective　on　CO2　emissions　than　a　negative　change　in　FDI　in　long　run.　Asymmetry　is　observed　in　the　only　magnitude　but　not　in　direction.　Our　study　implies　that　the　China　government　should　redesign　the　environmentally　friendly　policies　and　enforces　the　foreign　investors　to　role　play　in　environmental　quality.
