♦ Category: Industrial Processes and Product Use

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

♦ Activity: Soda ash consumption -

♦ Greenhouse gas: Carbon dioxide ( CO2 )

► Year 2012 —

● Greenhouse gas emission estimate —

Amount: 252,986 tonnes of CO2 Emitted (252,986 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [Soda ash consumption] * [Soda ash CO2 emission factor]

● Activity level used in calculations —

Activity: Soda ash consumption = 609,722,233,513 g (i.e. 609.72 thousand tonnes)
Basis: Calculation
Calculation: [National Soda Ash Consumption] * [CA to US Population ratio]
Reference: USEPA (2004). Emission Inventory Improvement Program. Technical Report Series, Volume 8: Estimating Greenhouse Gas Emissions, Chapter 6: Industrial Processes. US Environmental Protection Agency. Washington DC. http://www.epa.gov/ttn/chief/eiip/techreport/volume08/index.html
Reference: Not Applicable.

● Parameters and Constants used in calculations —

Parameter: National Soda Ash consumption = 5,060,000,000,000 g (i.e. 5.06 million tonnes)
Reference: USGS (various years). U.S. Geological Survey, Mineral Industry Surveys, Soda Ash. Accessed online at: http://minerals.usgs.gov/minerals/pubs/commodity/soda_ash/
Parameter: Soda ash CO2 emission factor = 0.415 g / g
Reference: IPCC (2006). 2006 IPCC Guidelines for National Greenhouse Gas Inventories, Prepared by the National Greenhouse Gas Inventories Programme, Eggleston H.S., Buendia L., Miwa K., Ngara T., and Tanabe K. (eds). Vol.3, Chap. 2: Mineral Industry. Published: IGES, Japan. http://www.ipcc-nggip.iges.or.jp/public/2006gl/pdf/3_Volume3/V3_2_Ch2_Mineral_Industry.pdf
Constant: CA to US Population ratio = 0.120498465121216
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 —

Amount: 0.415 g of CO2 per g
