Transport and Energy Consumption

Primary Energy Intensity

The primary energy intensity relates the total consumption of a region (including biomass) to its Gross Domestic Product. From 1980 to 2002, a significant reduction in energy intensity in the world (last column) has been observed, mainly due to efficiency improvement in industry and households.

The picture also shows that energy intensity reduction in transport is almost absent in rich countries, except in North America, which starts from a very high level of intensity.

This trend is confirmed also by other data: the following graph shows carbon dioxide (CO2) emissions by end-user in the UK, 1970 to 2001. Also in this case, it can be stated that the CO2 emission for transport in UK is increased in last 30 years both in relative and absolute values.

Therefore, it is apparent that the problem of reducing CO2 emissions is particularly serious in transport sector.
