The line graph compares 4 European nations in terms of the average carbon dioxide emissions over the period from 1967 to 2007.
It is noticeable that the UK was responsible for the highest level of CO2 emissions. Moreover, a downward trend can be observed in emissions from Sweden throughout the period.
From 1967 to 1977, the amount of CO2 emissions in the UK remained unchanged, at around 11 metric tonnes per person. During the same period, an upward trend can be seen in 3 other countries: Sweden Italy and Portugal, with an increase to about 10.5 tonnes, 6.5 tonnes and 2.5 tonnes respectively.
By 2007, CO2 emissions from Sweden had plummeted to nearly 5.5 metric tonnes, whereas the respective amounts came from Italy and Portugal had considerably risen to 5.5 tonnes and 7.5 tonnes. By contrast, there had been a reduction in the level of CO2 in the UK since 1977, with a gradual decrease of around 2 metric tonnes per person at the end of the period.
