The graph below shows average carbon dioxide (CO2) emissions per person in the United Kingdom, Sweden, Italy and Portugal between 1967 and 2007.

The line graph illustrates the CO2 footprints of each person in four countries over a 40-year period, starting from 1967.

Overall

while

the amount of Carbon Dioxide dumped by an individual in both the United Kingdom and Sweden experienced a downward trend, the figures for Italy and Portugal saw an upward trend.

Furthermore

, UK citizens are responsible for the most CO2 emissions throughout the entire timeline. Regarding the greater amount of CO2, in the UK there were roughly 11

tonnes

of CO2 footprints for a single citizen.

However

at the end

of the period and still became the lion’s share.

similarly

, one Italian released about 4

of CO2 in 1967. That witnessed a considerable climb up to around 7.8

surpassed the second rank of Sweden’s figure.
