The graph below shows average carbon dioxide (CO2) emissions per person in the United Kingdom, Sweden, Italy and Portugal between 1967 and 2007.

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 compares the average
emissions
of carbon dioxide in four countries - the
UK
,
Sweden
, Italy and Portugal - over a period of 40 years.
It is clear that
the
UK
has by far the highest CO2
emissions
over the period shown. Portugal,
on the other hand
, had
overall
the lowest
emissions
,
although
a slow but steady rise can be observed. In 1967, each inhabitant of the
UK
produced around 11 metric tonnes of CO2, which was significantly more than people in other regions. Italy and
Sweden
had average
emissions
of around 9 and 4.5 respectively. Portugal's residents generated only a negligible amount, just 1 metric tonne per person.
However
, the
UK
saw a decrease in CO2
emissions
by 4 metric tonnes per person after 40 years.
Sweden
's average
emissions
peaked in 1977 at over 10 metric tonnes and
then
gradually declined.
By contrast
, Italy and Portugal both had more CO2
emissions
. Italy's
emissions
surpassed
Sweden
's after 1987, and in 2007 the
emissions
of Portugal were at the same level as that of
Sweden
.
