The line graph compares the amount of carbon dioxide released per person in 4 different countries over a period of 40 years.
Overall, what stands out from the graph is that UK citizen’s emission was by far the highest. It is also interesting to see the only two among four nations had their figures increased during the period shown.
In 1967, the amount of carbon dioxide emitted by an average British stood at well under 11 metric tonnes, followed by Sweden with nearly 9 metric tonnes. Portuguese produced least carbon dioxide, and their figure was just about 1.2 metric tonnes.
Between 1967 and 2007, the amount of carbon dioxide released per an Italian increased dramatically to reach its peak of over 5.5 metric tonnes. The number of Portugal experienced the same trend, soaring from 4 to approximately 8 metric tonnes. While the UK reduced about two tonnes of emission over time, Sweden just saw a significant rise to its peak of around 10 metric tonnes of CO2 released in 1977, but it soon cut down the amount and overtook Portugal’s lowest position by 2007.
