The given line graph illustrates the

figure

for

carbon

dioxide

emitted by each person in four countries in Europe over a span of 40 years, from 1967 to 2007.

Overall

, the amount of

carbon

dioxide

emissions in the United Kingdom took the lead throughout the entire period,

while

that of Portugal had the lowest

figure

.

However

,

this

number in Italy and Portugal experienced an upward trend, whilst that of the United Kingdom and Sweden the opposite is true. Regarding each person who emitted

carbon

dioxide

in the UK, standing at the highest

figure

compared to others(about 11 metric

tonnes

of CO2 emissions)

initially

, after which it had slightly decreased to 9 metric

tonnes

in 2007.

Moreover

, the average

carbon

dioxide

emissions per individual in Sweden rose steadily to reach its peak of 10.5 metric

tonnes

in 1977, but

then

this

number hit a low in the next three decades, particularly plummeting to approximately 5 metric

tonnes

in 2007. Turning to Italy and Portugal, the data on the former started at just 4 metric

tonnes

in 1967 and

then

witnessed a marginal increase to nearly 8 metric

tonnes

after 40 years.

As well as

the aforementioned nation,

this

figure

for the latter soared to more than 5 metric

tonnes

in 1997(

while

that in 1967 just at 1 metric ton), and in the

last

decade,

this

number remained unchanged
