♦ Greenhouse gas: Carbon dioxide ( CO2 )

► Year 2005 —

● Greenhouse gas emission estimate —

Amount: 1,030,735 tonnes of CO2 Emitted (1,030,735 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [Geothermal power] * [Geothermal CO2 emission]

● Activity level used in calculations —

Activity: Geothermal power = 253,914,556,960,000 btu of Geothermal
Basis: Data
