How Ideo Concepts' Environment Management System (EMS) works - Measuring and Managing CALCULATION METHOD CO2 Emission from Freight Transport Operations
Activity-based approach (calculation method recommended for use by chemical companies)
CO2 emissions = Transport volume by transport mode x average transport
distance by transport mode x average CO2-emission factor per
tonne-km by transport mode
[Tonnes CO2 emissions = tonnes x km x g CO2 per tonne-km / 1.000.000]
Energy-based approach (calculation method recommended for use by transport companies)
CO2 emissions = fuel consumption x fuel emission conversion factor [Tonnes CO -emissions = liters x kg CO2 per liter fuel / 1.000]
