Útdráttur: Geothermal resource utilization, although widely accepted as a clean energy source, has also contributed to a decrease in air quality due to hydrogen sulphide and carbon dioxide emissions. Several studies have shown that CO2 emissions from geothermal/volcanic systems occur naturally and in some cases these natural emissions exceed the amount of CO2 emitted from the geothermal power plant utilizing the geothermal resource. This study was carried out to quantify the natural CO2 soil flux emissions from the Krafla geothermal field, identify the relationship between soil gas emission and the structural geology, and compare the results to the CO2 emissions from the Krafla power plant. The results of this study show that the total CO2 flux from soil degassing is approximately 14.13 tons/day for a survey area of 2.5 km2, a positive correlation between CO2 soil flux emissions and the structural geology of the area. CO2 emission from natural sources exceeds the emission from the power plant by approximately 3 times.
