The polyline graph depicts the information about approximate carbon dioxide emissions of each individual in the four different countries such as United kingdom, sweden, Italy and Portugal between 1967 and 2007.
It is clearly seen that, CO2 emission per capita in Sweden increased just over 8 metric tonnes to around 10, 2 tonnes within 1967 to 1977. After that the emission of corbon was sharply decrease from 1977 to2007 and it reached at nearly 3 metric tonnes in the last year. Similarly, CO2 emissions of Uk was virtually 10, 3 tonnes in the initial year 1967 then it slowly decided during 30 years time period. Lastly, in 2007 it observed 8. 3 tonnes. Furthermore, in italy per human emission was star above 4metric tonnes in the starting point. Whereas, after 10years it was reach approximately 6, 2 tonnes after this it was continuously followed the upward trend till 1997. However, in the next 10 years it was stable. While, Portugal per person CO2 emissions begin around 1 metric tonnes in the first year and it dragametically inclined untill 1997. In final, year 2007 it reached near about 5 metric tonnes.
Overall, it can be seen from the graph the England experienced the declined in the average of CO2 every human from 1977to 2007. Although, italy and Portugal were the most usage of carbon dioxide emission countries.
