the graph below shows average carbon dioxide emissions per person in the United Kingdom, Swedan, Italy and Portugal between 1967 and 2007.

The provided line graph depicts information on average carbon acid radiations per person in the UK, Sweden, Italy and Portugal from 1967 to 2007. A glance at the chart makes that clear that the carbon acid gas discharges per individual in Italy and Portugal grew,

whereas

it went down in the United Kingdom and Sweden throughout the period in question. Turning to details, the proportion of people emitting CO2 gas in the UK was just over 4 metric tonnes in 1967, which was followed by significant growth, reaching 7 in 2017. Meanwhile, 2017 year witnessed an increase in carbon dioxide emissions, showing close to 4, which specifically started from the lowest percentage of nearly under 2 MT. The United Kingdom experienced the peak in CO2 emissions per person in 1967, before falling slightly over the four decades, constituting about 9 MT in 2007.

Although

the figures for Sweden rose between 1967 and 1987, climbing from 8 to 10, emissions

then

plummeted to 7 metric tonnes, after that, there was a gradual decrease, representing 4 in 2017.
