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 chart illustrates how much greenhouse gas was discharged per individual across 4 specific nations during a period of 4 decades from 1967, measured in metric

tonnes

.

Overall

, the amount of CO2 in the

UK

and

Sweden

dropped slightly,

whereas

those in the rest encountered moderate rises. It is

also

reported that the vast majority of the greenhouse footprint was released by

UK

residents. Looking first at the amount of CO2 in the

UK

and

Sweden

, the former commenced the period at just shy of 11 metric

tonnes

, which was 2 metric

tonnes

more than the corresponding figure for the latter, at around 9 metric

tonnes

.

Thereafter

, there was a fair decline of 2 metric

tonnes

in the

UK

's CO2 emissions, ending at approximately 9 metric

tonnes

in 2007. Similar changes, but to a greater extent, can be observed in

Sweden

's data, decreasing to just north of 5 metric

tonnes

at the end

, despite reaching a peak of above 10 metric

tonnes

in 1977. Turning to the remaining nations, over 4 metric

tonnes

of CO2 was discharged by Italy citizens, with a marked rise to nearly 8 metric

tonnes

after 3 decades, and a final plateau towards the end. The amount of CO2 in Portugal showed a dramatic elevation from almost 1 metric tonne to about 5 metric

tonnes

during

this

period, reaching parity with 2007 's

Sweden

figure. "
