the graph below shows average carbon dioxide emissions per person in the United Kingdom, Swedan, Italy and Portugal between 1967 and 2007.

The presented graph provides information about a comparison of producing of carbon dioxide emission per individual in terms of various years in four different regions. As can be seen clearly from the graph half of the examined countries faced up increasing trends

at the end

along with

the other half faced a downsize direction. Meanwhile ,

Sweden

rose a fluctuation

in contrast

to the other steady trends during examined years. As is illustrated by the graph, Portugal began at less than 2 tons in 1967 and finished at almost 6 tons in 2007.

This

change experienced two different rises, one of them was till 1987 with a mount of nearly 4 tons

as well as

6

tones

in 1997. Same as Portugal , even though Italy witnessed a smooth growth and ended near 8

tones

, it has a slight variation in its tendency to rise.

On the contrary

,

Sweden

and the United Kingdom saw a substantial decrease over time.

While

the United Kingdom plummeted moderately between more than 10

tones

in 1967 aligned with nearly 8

tones

in 2007,

Sweden

reached a peak in 1977, thereby a decline during the remaining years was inevitable. Based on the sharp fall,

Sweden

finished at less than 6 tonnes, which is equal to the amount of Portugal at its maximum value.
