题目原文：The graph below shows 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.
The line graph shows the average amount of carbon dioxide emissions per person in the United Kingdom, Sweden, Italy and Portugal from 1967 to 2007.
Overall, the UK produced the highest amount of CO2 during the whole period, although its figure gradually decreased. Sweden also showed a downward trend after reaching a peak in 1977. By contrast, Italy and Portugal experienced steady increases, and Italy became the second highest country at the end.
In 1967, the UK had the highest emissions, at about 11 metric tonnes per person. Sweden was lower, at around 8.5 tonnes, while Italy and Portugal were much lower at about 4 tonnes and 1 tonne respectively. Ten years later, Sweden rose to just over 10 tonnes, which was its highest point, while the UK remained slightly above 10 tonnes.
After 1977, Sweden's emissions fell sharply to around 7 tonnes in 1987 and continued to decline to about 5.5 tonnes in 2007. The UK also dropped, but more slowly, finishing at about 8.5 tonnes. On the other hand, Italy increased steadily from 4 to nearly 8 tonnes over the period. Portugal also went up significantly, from about 1 tonne to just above 5 tonnes in 2007.

The line graph illustrates the average carbon dioxide (CO2) emitted per person in four European countries — the United Kingdom, Sweden, Italy, and Portugal — between 1967 and 2007.
Overall, the UK produced the highest amount of CO2 throughout the entire period, although its figure declined gradually. Sweden also exhibited a downward trend after reaching a peak in 1977. By contrast, Italy and Portugal experienced steady increases, with Italy becoming the second largest emitter by the end of the period.
In 1967, the UK had the highest emissions, at approximately 11 metric tonnes per person. Sweden was lower, at around 8.5 tonnes, while Italy and Portugal recorded significantly lower figures, at about 4 tonnes and 1 tonne respectively. A decade later, Sweden rose to just over 10 tonnes, reaching its peak, while the UK remained slightly above 10 tonnes.
After 1977, Sweden's emissions fell sharply to around 7 tonnes in 1987 and continued to decline to about 5.5 tonnes by 2007. The UK also dropped, but more gradually, finishing at about 8.5 tonnes. On the other hand, Italy increased steadily from 4 to nearly 8 tonnes over the 40-year period. Portugal also rose considerably, from about 1 tonne to just above 5 tonnes in 2007.
