♦ Category: Industrial Processes and Product Use

IPCC: 2D1 - Non-Energy Products from Fuels and Solvent Use - Lubricant Use
Sector: Transportation : Not Specified

♦ Activity: Fuel consumption - Lubricants

♦ Greenhouse gas: Carbon dioxide ( CO2 )

► Year 2009 —

Amount: 847,264 tonnes of CO2 Emitted (847,264 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [Fuel consumption] * [Heat content] * (1 - [Proportion of carbon stored]) * [Fuel CO2 emission]
