The graph below shows average carbon dioxide (Co2) emissions per person in United Kingdom,  Sweden, Italy and Portugal between 1967 to 2007.

The line graph gives information about average carbon dioxide emissions per person in four different types of categories including the UK, Sweden, Italy and Portugal from 1967 to  2007 . Units are measured in metric

tonnes

. It is noticeable that   the United Kingdom had a considerable increase Sweden had some fluctuation and fall

while

tonnes

and it fall gradually to around 8

tonnes

in 2007 and followed by , Sweden had the same amount that reached a pick of about 10 metric

tonnes

  in 1977

however

,  it  experienced considerable decrease just under 6 tonne

at the end

of that period .

By contrast

, in the first year of

this

,period Italian people's carbon dioxide emissions were 4

tonnes

but they increased to about 8

tonnes

  and Portugal had only 1 metric tonne  . It experienced a gradual increase and picked up just under 6

tonnes

in 2007.
