The graph below shows average carbon dioxide (Co2) emissions per person in the United Kingdom, Sweden, Italy, and Portugal between 1967 and 2007. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

The line graph illustrates the average discharge of carbon dioxide per person in four different areas from 1967 to 2007.

Overall

,

it is clear that

average CO2 emission per person in the

UK

and

Sweden

generally declined between 1976 and 2007,

while

emissions in Italy and Portugal gradually increased over the same period, with the

UK

consistently having the highest emission per person throughout the time frame, followed by

Sweden

, Italy, and

then

Portugal with the lowest emission. Regarding emissions, both the

UK

and

Sweden

exhibited a downward trend in per capita CO2 emissions. with the

UK

starting at the highest level in 1967 approximately 11 metric

tonnes

and gradually decreasing to remain the highest emitter by 2007(approximately 8 metric

tonnes

),

while

Sweden

, which started from a relatively high point of over 8 metric

tonnes

, experienced a more significant decline to nearly 6.

In contrast

, Portugal and Italy experienced an upward trend in CO2 discharge, Having started at a very low level of approximately 1 metric tonne in 1967 Portugal, which experienced the most dramatic rise, increased almost fourfold by 2007,

whereas

the trend for Italy had shown gradually increased, started in 1967 approximately 4 metric

tonnes

and nearly doubled by 2007.
