♦ Category: Energy

IPCC: 1A1ai - Fuel Combustion Activities - Energy Industries - Main Activity Electricity and Heat Production - Electricity Generation
Sector: Electricity Generation (Imports) : Specified Imports : Washington : Goldendale Generating Station (WA)

♦ Activity: Electricity generation - Primary fuel: Natural Gas

♦ Greenhouse gas: Methane ( CH4 )

► Year 2013 —

● Greenhouse gas removal estimate —

Amount: No data of CH4 Emitted (No data CO2 Eq.)
Basis: Calculation
Calculation: [Electricity Generation] * [CH4 emission factor]
Reference: ARB (2016). Technical support document on GHG inventory methodologies for the 2000-2014 inventory. See Discussion of emissions from electricity imports available at: ttps://

● Activity level used in calculations —

Activity: Electricity generation = 0 kWh of Primary fuel: Natural Gas
Basis: Data
Reference: ARB (2019). Summary of 2008 to 2017 data from California's Greenhouse Gas Mandatory Reporting Program. Reported emissions are available at:

● Parameters and Constants used in calculations —

Parameter: CH4 emission factor = 0 g / kWh
Reference: Not Applicable.
Constant: Global warming potential of CH4 = 25

● Greenhouse gas emitted per unit activity (derived from values listed above) —

Amount: Not Applicable
