How is the CO2 emission calculated?

Kuehne + Nagel’s GSCC is using the methodology developed by the Clean Cargo Working Group for the port to port transportation and the formula used by EcoTransit for truck or rail movements. For LCL shipments the formula uses 3 g/m3/km.

Who is the Clean Cargo Working Group (CCWG)?

The CCWG consists of the world’s largest shipping lines and works with shippers and freight forwarders in formulating universal standards for the measuring of CO2 emissions for the port to port sea transport of containers.

Who is EcoTransit?

EcoTransIT World calculates environmental impacts of different carriers accross the world, they provide an online tool for the emissions and energy consumption for all transportation modes based on an intelligent input methodology, large amounts of GIS-data and an elaborate basis of computation.

What formula did Kuehne + Nagel use for the calculation of the port to port CO2 emission?

Kuehne + Nagel used the aggregate trade-lane data reported by CCWG  ocean carrier members to the CCWG in 2012.

What is the purpose of the GSCC?

The GSCC allows customers and other parties interested to quickly calculate the total CO2 emission in kg per TEU (container).

What is CO2?

Carbon dioxide (CO2) is a non-flammable, colorless and odorless gas.  
CO2 emissions result from the combustion of heavy fuel oils as well as diesel oils when operating vessels. The amount of CO2 emissions are directly related to the amount of fuel burned. Therefore, marine fuel consumption is the basis for CO2 calculation. Carbon dioxide is the dominant greenhouse gas worldwide impacting climate change.

Are the terms used in the GSCC defined?

Carbon dioxide (CO2) - Greenhouse gas absorbing heat radiation from the Earth

Carbon dioxide equivalent (CO2e) - Quantity of CO2 that would have the same global warming potential, when measured over a specific timescale (generally, 100 years)

Nitrogen oxide (NOx) - Greenhouse gas and air pollutant

Sulphur dioxide (SO2) - Potent global warming gas

Particulate matter (PM10) - Small pieces of solid or liquid matter associated with the Earth's atmosphere

Energy consumption (EC) - Consumption of energy of power

Tank-to-Wheel (TTW) - Assessment related to the vehicle

Well-to-Wheels (WTW) - Assessment related to both vehicle and energy process
