♦ Greenhouse gas: Carbon dioxide ( CO2 )

► Year 2017 —

● Greenhouse gas emission estimate —

Amount: 94,371 tonnes of CO2 Emitted (94,371 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [Limestone applied to soils] * [limestone C emission factor] * [Molecular weight ratio of CO2 to C]

● Activity level used in calculations —

Activity: Limestone applied to soils = 215,458,190,119 g (i.e. 215.46 thousand tonnes)
Basis: Calculation
Calculation: [Total lime applied to ag soils in CA] * [Total limestone sold or used in CA] / ([Total limestone sold or used in CA] + [Total dolomite sold or used in CA])
