The graph below shows average carbon dioxide (Co2) emissions per person in the United Kingdom, Sweden, Italy, and Portugal between 1967 and 2007.

The line graph illustrates on average

carbon

dioxide

released by every individual in four different countries over the

period

of 40 years. It is clearly seen that, throughout the

period

the United Kingdom was the highest amongst the other four nations in releasing CO2 and it is

also

notable that there was a drastic decrease in Sweden’s CO2 emission, whilst the other two regions kept growing in leaking CO2 till the

year

2007.

To begin

with, in the

year

1967 England outflowed nearly 11 metric

tonnes

of

carbon

dioxide

into the air, after remaining steady for a decade it started dropping and reached close to 9 metric

tonnes

by the end of the

period

.

On the other hand

, Sweden was at approximately 9 metric

tonnes

in the

year

1967 and reached its peak by nearing 11 metric

tonnes

but

then

we can see a drastic dip from the

year

1977 till the rest of the

period

,

at the end

Sweden was identically matching with Portugal.

Furthermore

, the two countries which were lower compared to others in 1967 were Portugal just above 1 metric tonne and Italy around 4 metric

tonnes

, despite being lowest in the beginning, both the countries kept growing in releasing

carbon

dioxide

and

at the end

of the era Italy was second highest with nearly 8 metric

tonnes

in the amount of leaking CO2 and Portugal was as same as Sweden at just above 5 metric

tonnes

of

carbon

dioxide

in the air.
