The graph below shows average carbon dioxide emissions per person in the United Kingdom, Swedan, Italy and Portugal between 1967 and 2007.

The provided line chart displays the average CO2 production per person in four different countries

such

as the United Kingdom, Sweden, Italy and Portugal from the year 1967 to 2007.

Overall

, it can be seen in the UK and Sweden, there was a considerable decrease in carbon dioxide

emission

throughout the period of time,

while

the amount of co2

emission

increased significantly in Italy and Portugal in the given years. In 1967, the UK produced the highest carbon dioxide with around 11 metric

tonnes

. After that, it continuously declined till 2007 and stood at nearly 9 metric

tonnes

which is still at the top. In Sweden, average CO2

emission

amounted around just above 8 metric

tonnes

in the year 1967,

then

the rate of

emission

rose by nearly 2 metric

tonnes

and reached just above 10 metric

tonnes

in 1977. There was a steep decrease observed in co2 emissions from 1977 to 2007 which is around just below 6 metric

tonnes

. In Italy, the average rate of co2

emission

grew throughout the period when it began with just 4 metric

tonnes

, it doubled

at the end

of the year.

Lastly

, In Portugal, the rate of carbon dioxide produced was around just below 2 metric

tonnes

and

then

, it significantly increased till 1997 which is nearly 5 metric

tonnes

and after ,that it remained stable till 2007.
