You should spend about 20 minutes on this task. 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 compares the average amount of carbon dioxide released by each person between 4 countries over a period of 40 years.

It is clear that

the United Kingdom and Sweden mostly saw a downward trend,

whereas

Italy and Portugal led an upward trend throughout

this

period. in 1967 the United Kingdom was the prior producer with about 11 metric

tonnes

, and Portugal was the lowest with above 1 metric

tonnes

.

While

Sweden reached its peak in 1977 with just above 10

tonnes

and almost became the primary source of carbon emission, it gradually fell after that and in 1990 Italy overtook the first place in

this

debate and in 2007 Sweden tied up with Portugal, which had the lowest during these years. Between 1967 and 2007 Italy and Portugal saw a

similarly

rapid rise, about 4

tonnes

, meanwhile, the United Kingdom remained stable between 9 and 11 metric

tonnes

. Italy saw a significant boost at

first,

reaching 10 metric

tonnes

, and after 1977 fell under 6 metric

tonnes

,

therefore

is the smallest producer of carbon dioxide.
