A method for producing green olefins and green gasoline from renewable sources, the method comprising: providing CO2 and hydrogen as feed to produce methanol in a methanol reactor (102), reacting the methanol in an isothermal Methanol-to-Olefin (MTO) reactor (104) to produce an MTO reaction effluent, reacting the MTO reaction effluent in a plurality of separation columns to separate hydrocarbons, wherein the plurality of separation columns comprises a Deethanizer column (106), a Depropanizer column (108), and a Debutanizer column (110), hydrogenating a fraction of separated hydrocarbons in the Debutanizer column (110) with the hydrogen in a hydrogenation reactor (112), wherein the fraction of separated hydrocarbons from the Debutanizer column (110) comprises C5+ hydrocarbons; producing the green gasoline and Liquefied Petroleum Gas (LPG) by stabilizing the hydrogenated hydrocarbons in a gasoline stabilizer column (114); and producing the olefins by separating ethylene from C2 hydrocarbons using a C2 splitter column (116) and by separating propylene from C3 hydrocarbons using a C3 splitter column (117).
