The provided linegraph illustrates average carbon dioxide emissions per person in four countries comprising UK, Sweden, Italy and Portugal for 40 years starting from 1967.
In the first decade While Sweden demonstrated considerable elevation from approximately 8.5 tonnes of CO2 emissions to just above ten tonnes, United Kingdom’s CO radiation levels slightly declined from its initial 11 metric tonnes. Despite an initial climb Sweden faced significant drop to seven metric tonnes emission of carbon dioxide in the mid point, as well al UK which experienced a ton of decline. At the finish of the period both Sweden and UK displayed gradual decrease of CO2 radiations by one and just under two metric tonnes respectively.
On the other hand, Italy revealed noticeable growth up to roughly 6.5 tonnes, even though it started from low amount of carbon dioxide emission at just above 4 tonnes. Before remaining constant at alomost eight tonnes in the final decade, carbon dioxide levels were increasing modestly when the period was underway. Meanwhile, Portugal went through a climb in Carbon dioxide toxins from approximately one metric tonnes to just above 5 tonnes during the entire time span.
Generally, the United Kingdom and Sweden reduced CO2 levels, while Italy and Portugal reached their peak rates of emissions.
