The line chart compares the amount of carbon dioxide produced per person in four different countries from 1967 to 2007.
Overall,it is clear that the amount of CO2 emissions in Italy and Portugal increased during the period,while the United Kingdom and Sweden experienced a decline in carbon emission.
In 1967,the United Kingdom was the highest producer of CO2 which was close to 11 metric tonnes.It then declined steadily over the years,reaching around 9 metric tonnes in 2007.In contrast,Sweden started at around 9 metric tonnes in 1967 it then gradually rose to just over 10 metric tonnes in 1977 before decreasing significantly to about 5.5 metric tonnes in 2007.
Moving on to Italy and Portugal,in 1967,the amount of carbon dioxide produced per person in Italy was just over 4 metric tonnes.It then rose to around 8 metric tones in 1997 and remained stable until 2007. Similarly,Portugal which was the least producer of CO2 in 1967 saw a rapid increase in the production of CO2 reaching over 5.5 metric tonnes in 1997 and remained stable until 2007.
