The significant increase in energy demand over the study period also induces substantial increase in emissions of local pollutants in the country. Table 6 summarizes the results of total SO2 and NOx emissions under four scenarios during 2000–2050. Both SO2 and NOx emissions are estimated to increase considerably in the future: SO2 emission is estimated to increase by about 5.3 times under TB2 and by about 9.2 times under TA1; while NOx emission is estimated to increase by 3.6 times under TB2 and by 6.2 times under TA1 in 2050 compared to year 2000. The results also indicate that increase in SO2 emissions is relatively higher compared to increase in NOx emissions during 2000–2050 under all four scenarios. This is mainly due to increasing use of coal in electricity generation over the study period.
