You should spend about 20 minutes on this task. The graph below shows average carbon dioxide (CO2) emissions per person in the United Kingdom, Sweden, Italy and Portugal between 1967 and 2007. Summarise the information by selecting and reporting the main features, and make comparisons where relevants.

The graph illustrates the mean carbon dioxide

emissions

per individual in four countries, namely the UK,

Sweden

, Portugal and Italy from 1967 to 2007, a 40-year period. In detail, 1967 witnessed an average of about 11 metric

tonnes

of CO2

emissions

per person in the UK, which was the highest ever compared to the other countries at any given point. Followed by gradual declines until 2007, which was accounted for almost 9 metric

tonnes

of CO2

emissions

per capita.

Sweden

,

on the other hand

, started at an average of 8.5 metric

tonnes

in 1967.

Then

, it rose sharply by the end of the first

decade

exceeding 10 metric

tonnes

for each Swedish.

Furthermore

, Portugal started with subtle

emissions

at only 1 metric tonne individually in 1967.

However

, the numbers soared dramatically to the end of 1997 at 5 metric

tonnes

, which is 5-fold surprisingly. In the

last

decade

, they managed to level off their numbers to intersect with

Sweden

at 5.25 metric

tonnes

CO2

emissions

for each person, supposedly the least possible average in 2007.

While

Italy showed substantial increases in CO2

emissions

from about 4.5 to 6.2 metric

tonnes

in the first

decade

, they controlled the pace through the remaining period and coincided with

Sweden

's averages in the middle of the third

decade

, at almost 6.8 CO2 metric

tonnes

,

as well as

finished at around 7.5 metric

tonnes

CO2

emissions

per person.

Overall

,

while

the highest

emissions

throughout the period were in the UK, the lowest

emissions

were in Portugal.

Besides

,

Sweden

saw a fluctuation but finished with the least

emissions

as well.
