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

The line graph showcases how much an average resident in four various European countries accounted for the emissions of carbon dioxide between 1967 and 2007.

It is clear that

throughout the four decades, Italy and Portugal demonstrated an upward tendency,

while

others showed a reversed trend with some fluctuations shown by Sweden.

According to

the data, at the beginning of the period, Britons contributed the largest amount of carbonic acid gas with approximately 11 metric

tonnes

per person, which is roughly ten times as high as Portugal.

Although

there was a steady fall experienced by the UK, it finished at just over 8.

growth and a flat for 10 years after 1997,

whereas

Swish numbers demonstrated a considerable decrease after hitting a peak of around 10 metric

tonnes

in 1977. In the end, the figures were the same for both nations with just under 6

tonnes

per meter per person.
