♦ Category: Industrial Processes and Product Use

IPCC: 2G4 - Other Product Manufacture and Use - CO2, Limestone or Soda Ash consumption
Sector: Industrial : Not Specified

♦ Activity: CO2 consumption -

♦ Greenhouse gas: Carbon dioxide ( CO2 )

► Year 2007 —

● Greenhouse gas emission estimate —

Amount: 623,828 tonnes of CO2 Emitted (623,828 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [US CO2 emissions from CO2 consumption] * [CA to US Population ratio]
Reference: ARB (2016). Technical support document on GHG inventory methodologies for the 2000-2014 inventory. See Discussion of emissions from consumption of carbon dioxide available at:

● Activity level used in calculations —

Basis: None
Reference: Not Applicable.

● Parameters and Constants used in calculations —

Parameter: US CO2 emissions from CO2 consumption = 5,141,000,000,000 g (i.e. 5.14 million tonnes)
Reference: DATA NOT AVAILABLE - Values were extrapolated from years for which data were available.
Constant: CA to US Population ratio = 0.121343765687597
Reference: CDOF and US CB (various years). Current population estimates from the California Department of Finance (for California) and from the U.S. Census Bureau (for the entire US) were used to compute a ratio of California to US population. This ratio is used to scale down some national statistics to California.

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

Amount: Not Applicable
