♦ Category: Agriculture, Forestry and Other Land Use

IPCC: 3C2 - Aggregate Sources and Non-CO2 Emissions Sources on Land - Liming
Sector: Agriculture & Forestry : Ag Soil Management : Liming

♦ Activity: Dolomite applied to soils -

♦ Greenhouse gas: Carbon dioxide ( CO2 )

► Year 2009 —

● Greenhouse gas emission estimate —

Amount: 1,457 tonnes of CO2 Emitted (1,457 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [Dolomite applied to soils] * [dolomite C emission factor] * [Molecular weight ratio of CO2 to C]
Reference: CEC (2002). Inventory of California Greenhouse Gas Emissions and Sinks: 1990-1999. Publication #600-02-001F. November 2002. California Energy Commission, Sacramento. https://ww2.energy.ca.gov/2005publications/CEC-600-2005-025/CEC-600-2005-025.PDF

● Activity level used in calculations —

Activity: Dolomite applied to soils = 3,058,225,154 g (i.e. 3.06 thousand tonnes)
Basis: Calculation
Calculation: [Total lime applied to ag soils in CA] * [Total dolomite sold or used in CA] / ([Total limestone sold or used in CA] + [Total dolomite sold or used in CA])
