The graph below shows average carbon dioxide (CO) emissions per person in the United Kingdom, Sweden, ltaly and Portugal between 1967 and 2007.Summarise the information by selecting and reporting the main features, andmake comparisons where relevant.

The line graph illustrates the mean emissions of CO2 per individual in four countries from 1967 to 2007.

Overall

, it can be seen that the release of carbon dioxide in Italy and Portugal experienced an upward trend ,

while

in the UK and Sweden, it showed a downward trend . Despite

this

, the UK is the country with the most emissions of CO2 over the period .

To begin

with , in 1967 the emission of carbon dioxide in the UK was approximately 10 metric

tonnes

. It remained constant until 1997 but in 2007,the release of gas dropped to 8 metric

tonnes

.

Furthermore

, the emission of CO2 in Sweden decreased from 8 metric

tonnes

to 6 metric

tonnes

over the period .

Conversely

, the gas evolved in Italy , in 1967 , was nearly 2 metric

tonnes

. It rose dramatically to almost 6 metric

tonnes

in 2007 .

Moreover

, in Portugal , the emission of gas rose to 8 metric

tonnes

from 4 metric

tonnes

in 50 years .
