The graph below shows an average carbon dioxide (CO2) 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 illustrates the amounts of CO2 emitted by each person in four countries from 1967 to 2007.

It is clear that

each Swedish or

person released less CO2 over the period researched, but CO2 emissions in Italy and Portugal showed a rise. Citizens in the
