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 selcting and reporting the main features.

The line graph illustrates the amount of carbon dioxide which is released by individuals living in four countries from 1967 to 2007.

Overall

, the figure for carbon dioxide emissions increased in Italy and Portugal over a 40-year period.

In contrast

, during the same period, the UK and

Sweden

residents reduced their CO2 emissions. In 1967, just over 4 metric tonnes of CO2 were emitted by each person in Italy,

while

in

Sweden

people released approximately 1 metric tonnes. Over the next 40 years, the amount of CO2 emission in Italy doubled,

while

that of Portugal went up remarkably to just under 6. In terms of

Sweden

's and English's carbon dioxide production, both groups saw a substantial drop. There was a turning point in

Sweden

's emissions in 1977 (about 10 metric tonnes) which saw a substantial decrease of about 4 until 2007. People who live in England accounted for the most CO2 producers over the mentioned period.
