The graph shows the average carbondioxide emission per person in the United kingdom,Sweden, Italy,Portugal between 1997 and 2007.

The line graph illustrates the amount of carbon dioxide gas per person in four different regions, namely the United Kingdom,

Sweden

, Italy, and Portugal, in the span of time between 1967 - 2007.

Overall

, it can be seen that Italy and Portugal were relatively increasing their emissions every 10

years

,

whereas

the UK and

Sweden

were decreasing in general. Every country has its own starting point of the emissions level in 1967. Portugal and Italy may start at a low average, merely 1 metric tonne and 4 metric tonnes. But the two of these lands had a dramatic rise every 10

years

until 1997, just before they both were slightly rising for roughly 1 metric tonne in 2007.

On the other hand

, the United Kingdom and

Sweden

had different trends. The two of these regions were opposite to each other,

However

Sweden

, which had decreased by roughly 4 metric tonnes over the rest 30
