Grams of CO2 produced for every tonne carried one kilometre.
Air 903
Road 147

Freight Transport – another view
Another way of looking at freight transport is to calculate the distance is travelled when the weight of CarbonDioxide produced is equal to the weight of the load carried. Using the figures above.
Air 1,100 Km – about the length of the British Isles
Road 6,800 Km – a road journey to India
Sea 57,000 Km – more than the circumference of the world (40,000 Km)
Rail 68,000 Km – more than the circumference of the world (40,000 Km)
These may be used to estimate the CarbonDioxide generated by goods carried to the UK.
Carbon Dioxide from Air Freight
903 grams CO2 per kilometre tonne
1,100 Km carried will create Co2 equal to the weight carried
903 grams CO2 per tonne kilometre
What does this suggest?
Carbon Dioxide from Road Freight
147 grams CO2 per tonne kilometre
Carbon Dioxide from Sea Freight
18 grams CO2 per tonne kilometre
give 17.5 grams CO2 per tonne kilometre
Carbon Dioxide from Rail Freight
15 gm per tonne kilometre (?)

Per tonne carried, rail produces around 10% of the carbon dioxide produced by road transportation. – AEA Technology for SRA in October 2004
Road Freight is 147 gms COo2 per tonne kilometerer. So this makes 15 gm per tonne kilometer for rail freight. This may be too small. It come s in lower than sea freight.
