This study investigated the sustainability aspect of the fly ash (FA)-based one-part geopolymers (OPGs) with various combinations and amount of alkali activators (AA). The three groups of OPG were: the M-OPG activated with solely sodium metasilicate-anhydrous (Na₂SiO₃), the MH-OPG with Na₂SiO₃ and sodium hydroxide (NaOH), and the MC-OPG with Na₂SiO₃ and sodium carbonate (Na₂CO₃). The compressive strength, embodied carbon, embodied carbon index, embodied energy and embodied energy index were identified. Test result shows that the M-OPG and MC-OPG with the AA/FA ratio of 0.20 attained 83 MPa and 75 MPa of compressive strengths, respectively. The MH-OPG with AA/FA ratio of 0.15 attained 72 MPa of compressive strength. The embodied carbon and embodied energy of the OPGs were mainly contributed by the Na₂SiO₃-anhydrous. The values were lowered when the Na₂SiO₃-anhydrous were partially substituted with NaOH or Na₂CO₃. Increasing the AA content increased the embodied carbon and energy. The embodied carbon index (3.80 kg CO₂/m³/MPa) and embodied energy index (14.72 MJ/m³/MPa) of the MC-OPG with AA/FA ratio of 0.20 were the lowest. The outcome of this study supports the utilisation of Na₂CO₃ to partially substitute Na₂SiO₃ for the development of OPGs.
