The line graph represents the average amount of CO2 emissions that every person consumes in many countries: UK, Sweden, Italy and Portugal from 1967 to 2007. Overall, throughout 40 years, UK was always the country which had the highest amount of Co2 consumption per person, while Portuguese released the least emissions individually.

From 1967 to 1977, there were upward trends in 3 countries which were Portugal, Italy, Sweden. In 1977, the amount of average consumption per person in such 3 countries was 2 tonnes, just over 6 tonnes, and just over 10 tonnes, respectively. In contrast, UK almost stabilized at nearly 10 tonnes which was the same amount of Sweden.

After 10 years, there were glaring changes in 4 nations. The average rate of CO2 emissions released personally in Portugal continued to rise to 3 tonnes, while the amount in UK saw a gradual downward by 10 tonnes and still a tendency of decrease in later years till 2007.
