► Year 2000 —

● Greenhouse gas emission estimate —

Amount: 18,955 tonnes of CO2 From biogenic materials (18,955 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [Fuel combustion] * [Proportion of renewables] * [Heat content] * [Fuel CO2 emission]
Reference: ARB (2012). Upcoming technical support document on GHG inventory methodologies for the 2000-2010 inventory. Specific questions may be directed to ARB staff, see: http://www.arb.ca.gov/cc/inventory/contacts.htm

● Activity level used in calculations —

Activity: Fuel combustion = 41,027 ton of Tires
Basis: Data
