♦ Category: Energy

IPCC: 1A1ai - Fuel Combustion Activities - Energy Industries - Main Activity Electricity and Heat Production - Electricity Generation
Sector: Electricity Generation (Imports) : Specified Imports : Washington : HW Hill Landfill Gas (aka Roosevelt Biogas 1) (WA)

♦ Activity: Electricity generation - Primary fuel: Biomass

♦ Greenhouse gas: Carbon dioxide from biogenic sources ( CO2 )

► Year 2016 —

● Greenhouse gas emission estimate —

Amount: 168,880 tonnes of CO2 From biogenic materials (168,880 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [Electricity Generation] * [CO2 emission factor] * [Proportion of renewables]
Reference: CARB (2016). Technical support document on GHG inventory methodologies for the 2000-2014 inventory. See Discussion of emissions from electricity imports available at: https://ww3.arb.ca.gov/cc/inventory/pubs/reports/2000_2014/ghg_inventory_00-14_technical_support_document.pdf

● Activity level used in calculations —

Activity: Electricity generation = 145,462,200 kWh of Primary fuel: Biomass
Basis: Data
Reference: CARB (2021). Summary of 2008 to 2019 data from California's Greenhouse Gas Mandatory Reporting Program. Reported emissions are available at: https://ww2.arb.ca.gov/our-work/programs/mandatory-greenhouse-gas-emissions-reporting

● Parameters and Constants used in calculations —

Parameter: Biogenic fraction = 1

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

Amount: 1,161 g (i.e. 1.16 kg) of CO2 per kWh of Primary fuel: Biomass
