Average carbon dioxide emissions per person, 1967-2007

The graph represents carbon dioxide(co2) emissions for each person averagely in four countries from 1967 to 2007. Overall, Portugal and Italy had less cabon dioxide emissions at the first, however at the end, their Co2 emissions had grown. On the other hand United Kingdom and Sweden rates experienced a downward in this period. So the graph shows some fluctuations. At the year 1967 average of carbon dioxide was about 1 tonnes per person in the Portugal, then it rose to about 3 tonnes in 1987, next, in ten years it had risen sharply to approximatley 7 tonnes. between 1997 and 2007 it didn't significant change. Italy carbon dioxide emissions was a little more than 4 tonnes per person in 1967, but it rose suddenly to a little more than 6 tonnes between the years 1967 and 1977. then it had increased smoothly to about 7 tonnes until 1997, next, the trade hadn't any fluctuation until 2007. Although the UK had worse state at the begining, they can decreased their Co2 about 3 tonnes in this period. At the year 1967 the trade shows approximatlly 11 tonnes carbon dioxide per person, but it fell steadily to abot 9 tonnes in 2007. Sweden had significant fluctuation in this graph, first, their Co2 emissions was about 8. 2 tonnes, but in ten years it increased to more than 10 tonnes at the end of 1977. Next, the carbon dioxide emissions had decreased in a sharp way from 1977 to 1987, it continued to decreased to about 5 tonnes per person at the year 2007.
