A top London restaurant, we shall call it the Extravaganza, is impatient to receive its consignment of Alpure water and decides to have it air-freighted from France rather than wait for delivery by the 14-metric-ton truck. Compare the transportation energy for 100 bottles, with a total mass 104 kg including the water, over 550 km, by 14-metric-ton truck and by short-haul air freight. The relevant data are contained in Table 6.8. Is the embodied energy of the PET still the largest contribution to life energy?
