♦ Category: Energy

IPCC: 1A1aii - Fuel Combustion Activities - Energy Industries - Main Activity Electricity and Heat Production - Combined Heat and Power Generation (CHP)
Sector: Industrial : CHP: Industrial : Useful Thermal Output

♦ Activity: Fuel combustion - Tires

♦ Greenhouse gas: Carbon dioxide from biogenic sources ( CO2 )

► Year 1990 —

● Greenhouse gas emission estimate —

Amount: 6,443 tonnes of CO2 From biogenic materials (6,443 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [Fuel combustion] * [Proportion of renewables] * [Heat content] * [Fuel CO2 emission]
