Emission factor summary
Tank-to-wheel (TTW) emission intensity of fuel. Example application: Europe spark ignition truck. Retrieved from the Global Logistics Emissions Council Framework for Logistics Emissions Accounting and Reporting (2025). NOTE: The CO2e value for other gases includes methane (CH4) nitrous oxide (N2O) hydrofluorocarbons (HFCs) perfluorocarbons (PFCs) sulfur hexafluoride (SF6) and other fluorinated gases.
