The line graph show of amount of carbon dioxide emissions in 1976 to 2007 in four countries united Kingdom, Sweden Italy and Portugal.

The graph illustrates the

carbon

dioxide emitted by the United Kingdom, Sweden, Italy, and Portugal between the years 1976 and 2007. The United Kingdom and Sweden had the highest

carbon

emission

at the start of 1976 which later decreased by the

end

of 2007. Meanwhile, Italy and Portugal showed a lower release of gas in 1976, which showed a notable increase by the

end

of the

year

2007. The United Kingdom had a

carbon

emission

of 11 metric

tons

in the

year

1967, which later showed a steady decrease to 7 metric

tons

by the

end

of the

year

2007.

While

Sweden was marked to release 9 metric

tons

of

carbon

in the

year

1967, which increased to about 10 metric

tons

in 1977, and later showed a tremendous decline to approximately 5 metric

tons

by the

end

of 2007.

Whereas

, Italy and Portugal show a similar trend, both these countries showed an elevation in

carbon

emission

between 1967 and 2007, from 4.5 to 7 metric

tons

and 1 to 5 metric

tons

respectively.

In addition

, both these countries maintained their

emission

rate between the

year

1997 and 2007.
