The line chart illustrates average carbon dioxide (CO2) emissions per person in four different countries between 1967 and 2007, and the data are given in metric tonnes. At first glance, it can be seen that Sweden and the UK achieved to decrease the amount of their carbon footprints, whilst there was an increasing trend in CO2 emissions in Portugal and Italy over the period of 40 years.

At the beginning of this period, the UK had the biggest carbon footprint per person among the four, and although it was able to diminish its carbon emission over this time frame, it still had a higher proportion than the others at the end of the period. Another country that experienced a drop in carbon emissions was Sweden. Firstly, its carbon emission increased over the first ten-year period, reaching its peak at slightly over than 10 metric tonnes per person. Then, there was a dramatic continuous fall in carbon emission rates, finishing the period at a low of nearly five metric tonnes.

In contrast, it is clear that the carbon emissions of Italy and Portugal showed increasing similar patterns. Despite their lower emissions rates compared to others at the beginning, both countries had either higher or similar quantity of carbon emissions at the end of the period, 2007. The carbon footprints of these countries increased by approximately 4 metric tonnes within this 40-year period.
