The chart demonstrates the average amount of carbon dioxide emitted by individuals in 4 different nations from 1967 to 2007. Overall, it can be clearly seen that there were upward trends in the CO2 emissions in Italy and Portugal, while the case was reverse for the United Kingdom and Sweden. Looking at the graph more closely, in 1967, more than one ton and four tonnes of carbon dioxide were released in Portugal and Sweden, respectively. In the next 30 year period, there were gradual trends for both regions, before witnessing stabilization. The number leveled off at just under 8 tonnes for Italy, and around 5 tonnes for Portugal. It is also interesting to note that there were approximately 9000 and 11000 kilograms of CO2 emissions in Sweden and the UK, respectively, in 1967. Between 1967 and 1977, Sweden experienced growth of carbon dioxide emitted by individuals, which was more than 10 tonnes. Afterward, there was a drop to almost 5 tonnes in 2007, that was practically the same as Portugal’s. Besides, the UK’s figure fell steadily, to approximately 9 tonnes at the end of the given period.
