The graph below shows average carbon dioxide (CO₂) emissions per person in the United Kingdom, Sweden, Italy and Portugal between 1967 and 2007. Summarise the information by selecting and reporting the main features, and make comparisons where relevant

The graph depicts the average chemical compounds per person in four countries from 1967 to 2007.

Overall

, it is noticeable that the United Kingdom had the highest chemical emissions,

while

Sweden and Portugal lowest.

Moreover

, there is a significant uplift in Portugal and Italy ,

whereas

Sweden and the United Kingdom decreased.

To begin

with, the United Kingdom accounted for over 10 CO2 emissions ,

therefore

it declined gradually from 10 in 1977 to under 8 in the final years. The figure for Sweden improved from over 8 to approximately 10 in 1977 before levelling out to 5 in the final epoch. In terms of Italy , it accounted for 4 which increased marginally to under 8 in 1997 before maintaining the same level between the next 5 aeon. Portugal had roughly 1 which rose progressively to under 4 in 1997 before going up to 5 in the final cycle.

However

, Portugal obtained the lowest CO2 emissions over the period in question.
