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 discharging the average

amount

of greenhouse gases per person in the four countries, the

UK

, Sweden, Italy, and Portugal from 1967 to 2007.

Overall

, it can be seen that the average

carbon

dioxide

emissions in Italy and Portugal experienced an increase

while

releasing

carbon

dioxide

in the

UK

and Sweden decreased notably over the 40 years, albeit, the

UK

represented the highest

amount

of

carbon

dioxide

emission

. The

amount

of

carbon

dioxide

emission

in Italy surged from 4 metric

tonnes

to over 6 metric

tonnes

in the first

decade

,

then

experienced a stable increase and in the

last

decade

, reached a plateau and stood under 8 metric

tonnes

although

Portugal in the first 30 years, saw a sharp increase in

carbon

dioxide

emission

,

similarly

, in the

last

decade

with just under 6 metric

tonnes

reached a plateau.

While

the

UK

discharged more than 10

tonnes

metric 1967, the

amount

of greenhouse gas declined significantly and in 2007 stood at above 8 metric

tonnes

. Sweden in the first

decade

witnessed a surge, amounting to approximately 10 metric

tonnes

;

however

, the average

carbon

dioxide

emission

from 1997 to 2007 decreased dramatically and stood under 6 metric

tonnes

.
