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

The line graph provides information on the average carbon dioxide

emissions

per person in 4 European countries: the UK,

Sweden

, Italy, and Portugal over a 40-year period from 1967 to 2007. In general, the amount of CO2

emissions

fell in the UK and

Sweden

,

whereas

the numbers rose in Italy and Portugal over

this

period. With regard to the downward trend, British people were responsible for approximately 11 metric

tons

of

emissions

in 1977 and

this

number fell gradually to almost 9 metric

tons

by 2007.

Additionally

, in

Sweden

, it started with almost 8 metric

tons

of carbon

emissions

at the beginning and

then

peaked at roughly 11 metric

tons

in 1977.

This

trend went down marginally to 6 metric

tons

at the end

of the period. In terms of increase, both Italian and Portuguese people were starting to increase the amount of CO2

emissions

. In Italy,

emissions

of carbon dioxide were nearly 4 metric

tons

at the beginning, and it rose to 8 metric

tons

by 2007. Meanwhile, in Portugal,

emissions

were under 2 metric

tons

in 1967 and it reached 6 metric

tons

by 2007, similar to

Sweden

.
