The given line graph provides information about the average discharge of carbon dioxide by each person in four different countries from 1967 to 2007. And the units are measured in metric tons.
Overall, it can be seen that the average carbon dioxide released by Portugal and Italy showed an upward trend while Sweden and UK followed a decrease during the period.
To start with, in 1967, number of carbon dioxide breakdowns in Portugal was the lowest, at around 1 metric ton. But it rose gradually and reached at almost 6 Matric tons in 2007. On the other hand, in United Kingdom the rate of carbon dioxide emissions started at 11 metric tons which fell slowly and stood at 7 metric tons in 2007.
In addition to this, the breakdowns of carbon dioxide in Italy experienced a increase between 1967 and 2007. The figure for Italy began at approximately 4 metric tons which finished by 7 metric tons in 2007. Meanwhile,from 1967 to 2007, the amount of carbon dioxide emissions in Sweden in increased sharply. But the figure dropped slowly from 1976 to 2007 at nearly 7 Matric tons.
