The graph below shows average carbon dioxide (CO2) emissions per per person in the United Kingdom, Sweden, Italy and portugal between 1967 and 2007.

The line graph illustrates the amount of carbon dioxide

emissions

an individual produced in the United Kingdom, Sweden, Italy, and Portugal from 1967 to 2007.

Overall

, it can be seen that, through 40 years, the average carbon dioxide

emissions

per person in the United Kingdom and Sweden despite some fluctuations, had a declining trend.

Whereas

, Portugal and Italy's rates increased over the past years.

to begin

, in 1967 the amount of CO2 emitted by Swedish and British people stood at approximately 8.1 and 10 tonnes.

However

, over the following 10 years, there was a sharp increase to 10 tonnes in Sweden.

, 1977 saw a dramatic decline in the CO2

rate

, which was followed by a gentle fall.

Similarly

, the UK followed a similar pattern.

At the end

of

this

period, the

rate

hit a low of 5.8 in 2007.

In contrast

, in countries with the opposite trends, Portugal and Italy, in 1967 the CO2

emissions

rate

stood at 1.8 and 4. As the chart shows, Portugal had the lowest CO2

rate

per person in 1967.

Finally

, from 1967 to 1997, CO2

emissions

in Italy and Portugal steadily rose.
