► Year 1990 —

● Greenhouse gas emission estimate —

Amount: 274,545 tonnes of CO2 Emitted (274,545 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [Fuel consumption] * [Heat content] * (1 - [Proportion of carbon stored]) * [Fuel CO2 emission]

● Activity level used in calculations —

Activity: Fuel consumption = 227,262,000 gal of Natural gas liquids
Basis: data
Reference: DATA NOT AVAILABLE - Value for this year is assumed to be equal to the average value for the latest 5 years with available data.

● Parameters and Constants used in calculations —

Parameter: Fuel CO2 emission = 0.0668 g / btu

● Greenhouse gas emitted per unit activity —

Amount: 1,208 g (i.e. 1.21 kg) of CO2 per gal of Natural gas liquids
