The graph below shows an average carbon dioxide (CO2) emissions per person in the United Kingdom, Sweden, Italy and Portugal between 1967 and 2007. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

This

line graph provides information about the average carbon dioxide (CO2) emissions per person in four countries(the United Kingdom,

Sweden

, Italy and Portugal) between 1967 and 2007.

Overall

,

it is clear that

the UK is the top emitter all the time, though it kept decreasing from 1967 to 2007.

Similarly

, the figure for

Sweden

decreased, except between 1967 to 1977. In the contrast, the emissions of CO2 from Italy and Portugal kept increasing. CO2 emissions in the United Kingdom decreased from 11 metric

tonnes

in 1967 to 9 metric

tonnes

in 2007. After an increase from 9 metric

tonnes

in 1967 to a peak at over 10 metric

tonnes

in 1977, the CO2 of

Sweden

decreased to less than 6 metric

tonnes

in 2007, which was surpassed by Italy in 1987 and Portugal in 2007. The figure for Italy and Portugal increased from more than 4 metric

tonnes

and 1 metric tonne in 1967 to more than 7 metric

tonnes

and 5 metric

tonnes

respectively in 1997, before levelling off until 2007. By the end of the given period, Italy took second place

instead

of

Sweden

, and Portugal took third place, which had the top increase of the four countries.
