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 chart illustrates the average amount of carbon dioxide (CO2) emissions per person in the United Kingdom, Sweden, Italy, and Portugal from 1967 to 2007.

Overall

, the UK had the highest emissions throughout the 40-year period,

although

its figure decreased consistently. The UK started with the highest emissions at around 11 metric

tonnes

per person in 1967, and

this

figure declined gradually to nearly 9 metric

tonnes

by 2007. Sweden, the second-highest emitter until 1987, began at approximately 9 metric

tonnes

in 1967. It rose sharply to just over 10 metric

tonnes

in 1977 but

then

fell significantly, reaching almost half of its peak value by 2007. Italy saw a steady increase, starting from just over 4 metric

tonnes

in 1967 and rising to just under 8 metric

tonnes

by 1987.

This

level remained constant for the rest of the period. Portugal, the lowest emitter throughout, saw a dramatic increase from around 1 metric tonne in 1967 to about 5 metric

tonnes

in 1997, reflecting a fivefold increase before stabilizing at these levels by 2007.
