head of the population of Britain,

, Italy and Portugal in the years from 1967 to 2007.

Overall

, it can be seen that the UK was the leading country regarding the CO2 emissions issued per person during

this

40-year period,

although

, there was a decrease in

this

emission through the years, similar to the score in

Sweden

.

In contrast

, there was a rise in data in Italy and Portugal. In 1967 the major amount of carbon dioxide per person was discharged from the United Kingdom with around 11 metric

tons

, but,

however

,

this

quantity declined to about 9 in 2007. At the beginning of the period,

Sweden

's emission was just over 8 metric

tons

, and in general, it decreased to 5.5 in 2007 with a brief climb to over 10 metric

tons

in 1977. In Portugal and Italy, the releasement in 1967 was 1.5 and just over 4 metric

tons

, respectively. These numbers increased sharply until 2007 when they were almost 8 metric tonnes in Italy and 5.5 in Portugal, as the latter had the same issue as

Sweden

for the year.
