The line graph illustrates the average emissions of carbon dioxide by each person in several countries in Europe from 1967 to 2007

The carbon dioxide emanation per individual in Italy, Portugal,

Sweden

and the United Kingdom, between 1967 and 2007 is clearly accessible in the given graph.

Overall

, CO2

emission

per person averages up to 12 metric

However

, in the year 2007, results clearly stated that all the countries except UK and

Nevertheless

, among the four, in a span of 40 years, UK and
