The line graph illustrates the average carbon dioxide emissions per person in the United Kingdom, Sweden, Portugal, and Italy from 1967 to 2007.
Overall, it is evident that there were significant fluctuations in carbon dioxide emissions per person in the four countries over the forty-year period. Notably, Italy and Portugal experienced substantial increases in emissions, whereas the United Kingdom and Sweden saw considerable decreases. Furthermore, there was a sharp incline in emissions in Sweden between 1967 and 1977, followed by a notable decline.
Looking specifically at Italy and Portugal, both countries experienced a dramatic surge in emissions. Italy’s emissions more than doubled from 4 metric tonnes in 1967 to 8 metric tonnes in 2007, while Portugal’s emissions increased from 1 to 5.5 metric tonnes over the same period.
In contrast, the United Kingdom and Sweden witnessed a decline in emissions. The United Kingdom’s emissions dropped from 11 metric tonnes in 1967 to just above 9 metric tonnes in 2007, whereas Sweden’s emissions decreased from 9 to 5.5 metric tonnes over the same period
