The graph below shows average carbon dioxide (CO2) emissions per person in the United Kingdom, Sweden, Italy and Portugal between 1967 and 2007.

The line chart illustrates the average CO2 emissions for each person in four European countries in the years 1967 to 2007.

Overall

, it can be easily seen that the UK had the

first rate

in the emission of carbon dioxide in the period.

On the other hand

, Portugal had the lowest rate.

In addition

, Sweden was the second emitter at the beginning of the period but it has a significant fall until 2007. The United Kingdom emitted approximately 11 metric

tons

but it had a slight decrease to about 9 metric

at the end

of the period.

Also

, Sweden emitted about 9 metric

in 1967 and its emission increased to reach a peak of 10.5 metric

in 1977 and
