The given line graph illustrates the figure for carbon dioxide emitted by each person in four countries in Europe over a span of 40 years, from 1967 to 2007.

The line chart illustrates the amount of CO2 that people in four nations produced for four decades.

Overall

, people in the United Kingdom and Sweden tended to emit less CO2

whereas

the amount of CO2 produced in Italy and Portugal increased. The United Kingdom continued to be the largest producer of CO2 with Portugal being the least throughout the whole examined periods. Starting with the countries whose emission of CO2 tended to rise, Italy showed a
