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 on the emissions of carbon dioxide in four nations from 1967 to 2007. Overall, while the amount of CO2 emitted by Italy and Portugal rised throughout the whole period, the figures for the UK and Sweden showed a reverse trend.
In 1967, Italy produced the least amount of C02, at approximately 1 metric tonne. 40 years later, the figure increased considerably by 5 times. Similarly, the figure for Portugal also doubled to nearly 8 metric tonnes.
By contrast, there was a decline in carbon dioxide emission in Britain, from about 11 to 9 tonnes. On the other hand, the emission in Sweden saw a sharp rise by 2 tonnes in the first 10 years of the period before experiencing a sharp drop to 7 in 1987. At this point, it got exceeded by the figure for Italy. In 2007, Sweden and Italy emitted the same amount of carbon dioxide, at slightly over 5 metric tonnes.
