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

The provided line graph illustrates how much carbon dioxide (CO2) was emitted per person in the United Kingdom, Sweden, Italy, and Portugal over 40 years period from 1967 to 2007. Units are measured in metric tonnes.

Overall

, it can be clearly seen that

while

the

two

countries with the highest level of

emissions

at the start decreased moderately, the

two

countries with the lowest amount of production increased significantly.

As a result

,

although

the United Kingdom remained the most producer of CO2 throughout the given period, the gap between the highest and lowest was smaller

at the end

. In terms of the

two

nations with high levels of

emissions

in 1967, the UK was the first rank which accounted for 11 in 1967,

the figure experienced a steady fall over 40 years to the end at under 10.

Likewise

, Sweden started at over 8, and even though reached its peak at 10 in 1977, it

then

fell significantly to the end at approximately under 6. Regarding the

two

countries with the low levels at the start, in 1967, the figures for both Italy and Portugal were far lower than the UK starting at above 4 and below 2, respectively. In the following 30

the production of

Similarly

, the figure for Portugal climbed noticeably by roughly 4. After that, the amount of
