The Graph below shows average carbon dioxide (CO2) emissions per person in the United Kindom, Sweden, Italy and Portugal between 1967 and 2007. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The graph provides information about exhalation of CO2 per person in 4 countries (UK, Sweden, Italy and Portugal) from 1967 to 2007. CO2 emission measures in metric tonnes. Overall, amount of UK and Sweden people emits CO2 shows downward trends, on the contrary, Italy and Portugal illustrates upward trends in discharge of CO2 in given period of time. In 1967, about 0. 6 metric tonnes of CO2 discharged in Portugal, while this numbers accounts for 4. 1, 8. 2 and 10. 2 in Italy, Sweden and UK respectively. The numbers went down markedly and hit the bottom (about 8. 3) in 2007 in UK. Whereas, CO2 emission per person in Sweden went up slightly until next decade and reached to 10. 1 in 1977, in the following next 3 decades there was sharp decline in numbers and reached to around 4. 8 in 2007. In contrast, there was significant growth in metric tonnes in Italy from 4 in the beginning to around 6. 9 in 2007. Similarly, the number rose dramatically in Portugal from 0. 6 in 1967 to 4. 8, as same as Sweden in 2007.
