The graph conveys data on the emission of a greenhouse gas called carbon dioxide, per person in European nations namely United Kingdom, Sweden, Italy and Portugal spanning across four decades from 1967 to 2007. The units are measured in tonnes.
Inclusive of all the given data, it is eminent that United Kingdom led in carbon dioxide emissions as opposed to Portugal with least emissions throughout. Although, Sweden showed fluctuations, but it managed to go downhill by 2007. However, Italy displayed steady growth in this arena.
To commence with, United Kingdomís CO2 emission gradually declined by 2 tonnes and in 2007, 9 tonnes of CO2 was released. As far as Sweden is concerned, it showed rapid increase to around 10.2 tonnes (approx.) from 9 tonnes (approx.) in 1997, before plummeting to 7 tonnes (approx.) in 1987 and 5.7 tonnes (approx.) in 2007.
Furthermore, Italy let out 4 tonnes (approx.) in 1967, which then kept on surging till it reached around 8 tonnes in 2007. In another scenario, Portugalís CO2 emission skyrocketed from around 1 tonne in 1967 to approximately 5.7 tonnes in 2007.
To sum up, Italy and Portugal showed rapid decrease and increase in CO2 emissions respectively. Moreover, United kingdom and Sweden showcased substantial decrease and increase respectively.
