Environmental　degradation　has　become　a　global　issue　that　requires　recent　studies＇　emphasis.　Non-renewable　energy　is　a　significant　factor　in　environmental　degradation.　Thus,　policymakers　have　switched　their　focus　towards　promoting　renewable　energy　production　and　consumption　in　all　economic　activities　to　secure　low　carbon　economies.　Given　this　scenario,　the　present　study　aims　to　investigate　the　effect　of　energy　consumption　(both　renewable　energy　and　non-renewable　energy)　on　carbon　emissions　under　Environmental　Kuznets　Curve　hypothesis　in　the　world＇s　next　fastest　emerging　economies　named　N-11　economies　over　the　period　1990　to　2020.　The　present　research　has　employed　the　recently　introduced　Method　of　Movement　Quantile　Regression　approach　to　examine　the　association　among　the　variables.　The　study＇s　primary　findings　reveal　that　the　consumption　of　renewable　energy　has　significant　contribution　in　environmental　quality　improvement　at　all　quantiles　(0.10–0.90)　whereas　non-renewable　consumption　has　positive　contribution　in　deterioration　of　the　environmental　quality　only　at　lower　quantiles　(0.10–0.40).　Moreover,　the　effect　of　economic　growth　turns　from　positive　to　negative　at　medium　to　higher　quantiles　(0.10–0.30),　which　is　an　indication　of　the　validity　of　Environmental　Kuznets　Curve　hypothesis　in　these　countries.　Various　policies　are　recommended　to　the　policymakers　based　on　the　findings　of　the　study.　©　2022　Elsevier　Ltd
