average carbon dioxide emissions per person in the UK between 1967 and 2007

The graph gives illustrates the amount of discharged co2 by individuals in 4 separate countries from 1967-2007, a period of 40 years. Overall, the CO2 emissions in the United Kingdom were higher than those of other countries. Gradually, carbon dioxide releases in UK and Sweden were decreased while they increased in Italy and Portugal by the end of the given period. At the beginning, in Portugal the CO2 emissions were about 1. 2 metric tonnes per person. The graph very clearly shows a rise every decade and was almost five times higher than its initial value. Similarly, an average person in Italy generated approximately 4. 2 metric tonnes of carbon dioxide which also increased till 1977. From 1977 to 1987, the emissions of CO2 dropped by a small amount but gradually grew after and rose to 7. 8 metric tonnes at the end. In 1987, Sweden was about 8. 3 metric tonnes CO2 per person. This figure reached to its peak in 1977 and then decreased to 5 metric tonnes and eventually it touches the lowest point, less than nine metric tonnes in 2007.
