CO2 tax revenues. The total CO2 tax revenues of the two-country economy increased from 264.1 to 333 units and the CO2 revenue gap between the two countries increased to 92.45 monetary units (Fig. 6). The significant difference of the CO2 tax revenues of the two countries are caused by the different technological levels expressed in Table 5, the different respective CO2intensities (Table 4), and the different growth rates of the CO2 tax in the analysed period. The CO2 tax in country B is lower than in country A as an institutional appreciation for its strategy of declining economic growth.
