♦ Greenhouse gas: Methane ( CH4 )

► Year 2004 —

● Greenhouse gas emission estimate —

Amount: 541.37 tonnes of CH4 Emitted (13,534 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [Livestock population] * [CH4 emission factor]

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

Amount: 5,000 g (i.e. 5 kg) of CH4 per head of Goats
125,000 g (i.e. 125 kg) of CO2eq. per head of Goats
