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 provides information about the

amount

of CO2 which each person emits in four different nations over a period of 40 years.

Overall

, the

amount

of CO2

emissions

in the UK and Sweden follows a downward trend.

However

, the figure for average carbon dioxide

emissions

in Italy and Portugal has risen over the entire period.

To begin

with, the figure for CO2

emissions

per person in Italy and Portugal is near 4 and 1 metric

tonnes

respectively in 1967.

Whereas

, they both followed an increasing trend and reached almost 5 and 8 metric

tonnes

respectively

at the end

of the period.

In addition

, the

amount

of carbon dioxide

emissions

which was produced by British people was 11 metric

tonnes

in 1967,

nonetheless

, it saw a gradual decline and stood at 9 metric

tonnes

in 2007.

Furthermore

, there was a rapid rise from 9 to just over 10 metric

tonnes

in the

amount

of Swedish people’s carbon dioxide production from 1967 to 1977. After which, it saw a significant decline of 5 metric

tonnes

in the subsequent 30 years.
