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 gives information about the average CO2

emissions

per individual in four countries,namely the United Kingdom,

Sweden

, Italy, and Portugal, from 1967 to 2007.

CO2

emissions

increased in Italy and Portugal,

whereas

they decreased in the United Kingdom and

Sweden
