♦ 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 2002 —

● Greenhouse gas emission estimate —

Amount: 2,235 tonnes of CO2 Emitted (2,235 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.

● Activity level used in calculations —

Activity: Dolomite applied to soils = 4,691,229,582 g (i.e. 4.69 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])
