The　novel　pi-electron　donor-based　deep　eutectic　solvents　(DESs)　have　been　shown　to　be　a　promising　type　of　absorbent　with　excellent　performance　on　toluene　absorption.　However,　their　greenness　or　sustainability　is　still　unclear.　Thus,　to　bridge　the　gap　and　give　a　comprehensive　evaluation　for　their　industrialization　potential,　the　life　cycle　assessment　(LCA)　was　used　to　evaluate　the　potential　environmental　impacts　incurred　from　their　production　and　usage　for　absorbing　toluene.　The　environmental　profiles　are　also　compared　with　that　of　popular　choline　chloride　(ChCl)　based　DES,　common　organic　solvent　triethylene　glycol　(TEG)　and　ionic　liquid　([EMIM][Tf2N]).　The　results　indicate　that　among　the　involved　hydrogen　bond　acceptors　(HBAs),　TEBAC　generally　imparts　lower　environmental　impacts　than　other　HBAs　but　has　higher　impacts　than　ChCl.　Although　TEBAC-PhOH　is　not　the　most　environmentally　friendly　absorbent　during　the　production　stage,　its　outstanding　absorption　performance　minimizes　the　environmental　impact　when　absorbing　the　same　mass　of　toluene.　Furthermore,　the　environmental　impacts　of　the　toluene　absorption　process　using　TEBAC-PhOH　is　significantly　lower　than　that　of　[EMIM][Tf2N],　slightly　lower　than　TEG.　Therefore,　considering　both　absorption　performance　and　environmental　impacts,　TEBAC-PhOH　can　be　used　as　a　promising　＂green　and　sustainable＂　toluene　absorbent　to　traditional　absorbents　and　ionic　liquids.
