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

This

line chart illustrates carbon dioxide waste per person in four different countries over almost a 40-year duration. From an

overall

perspective,

it is clear that

Italy and Portugal experienced a gradual increase between 1967 and 2007.

However

, the other two countries (the United Kingdom and Sweden) show a downward trend during the same time period.

According to

surging from almost 9 to 10 metric tonnes of greenhouse gas from the span of 1967 to 1977, respectively.

Nonetheless

, there was a sharp drop afterwards until 2007.

On the other hand

, the United Kingdom went through a plunge through the whole period.

In contrast

, Portugal accounts for an increase from 1967 to 2007.

Similarly

, Italy

also

represented an upward trend, but it showed some fluctuation from 1977 to 1997, and it flattened out,

finally

. In conclusion, Italy and Portugal emit more carbon dioxide gases than the other two countries.
