The graph shows the average carbon emissions per person in four countries between 1967 and 2007

The line chart illustrates the average

carbon

emissions from each

person

in

four

different countries through

four

decades, from 1967 to 2007.

Overall

, per capita,

carbon

emissions in Italy and Portugal increased steadily,

while

the United Kingdom faced a gradual decline, and

Sweden

hit a peak in 1977

then

significantly dropped until the end of 2007. At the start of the period, 1967, Portugal in terms of the

carbon

footprint was only around 1.2 metric

tonnes

per

person

, which is the lowest among the

four

countries.

On the contrary

, people in the United Kingdom emitted almost 11 metric

tonnes

, which is the highest among the

four

countries. Through the improvement in renewable energy and effective education.

Although

the United Kingdom is still the country which produces the most amount of

carbon

dioxide, people living there reduced by roughly 2 metric

tonnes

, from almost 11 to a little under 9. Look into Italy and Portugal, their trend of increase is quite the same, both grew around 4 metric

tonnes

per

person

. Italy ended a little lower than 8, meanwhile, Portugal ended at approximately 5.

Moreover

,

Sweden

reached a high peak in 1977, which was slightly above 10 metric

tonnes

per

person

, and significantly dropped to 7 metric

tonnes

in 1987. At the same time, Italy's

carbon

emissions first exceed

Sweden

's.

At the end

of the period, 2007, the data in

Sweden

and Portugal were identical, around 5.5.
