The charts below show average carbon dioxide emission per person in the United kingdom, Sweden, Italy and portugal between 1967 and 2007.

The chart illustrates the

number

of carbon dioxide

emissions

per person in 4 countries in 40 years. Measured in metric

tonnes

.

Overall

,

it is clear that

there were 2 countries that faced an increase, namely Italy and Portugal,

while

two others felt a decrease. Looking at the line in 1967, the United Kingdom was the most significant donor of carbon dioxide

emissions

, approximately 11 metric

tonnes

, and they slightly decreased until 2007, accounting for 9 metric

tonnes

.

In addition

, the second contributor of CO2

emissions

was Sweden, with a

number

of contributions of almost 9 metric

tonnes

and surged in 1977 to reach 10 metric

tonnes

and plummeted in 1987 and slightly decreased until 2007, approximately 5 metric

tonnes

. Turning to the 2 countries (Italy and Portugal), Portugal was the lowest philanthropist in 1967 and rose until 1997 with the

number

of 5 metric

tonnes

, and slightly increase reached the same

number

as Sweden, around over 5 metric

tonnes

.

Furthermore

, Italy contributed CO2

emissions

in 1967, around 4 metric

tonnes

, and rose by approximately 7 metric

tonnes

.
