The graph illustrates the average Carbon Dioxide(CO2) which is emitted per person between the year 1967 and 2007 in the countries like United Kingdom, Sweden, Italy and Portugal. Units are measured in metric tonnes.
Overall, in Italy and Portugal the Co2 emission has increased over the years in contrast to other two countries, UK and Sweden whose CO2 emission has decreased.
In 1967, Italy had nearly 4 units of CO2 emission and in 1977 it rose sharply to nearly 6 units and it increased a little from 1977 to 1997. It stayed almost consistent from 1997 to 2007 with nearly 8 units. Portugal followed a similar situation with almost 1 unit at 1967 and gradually increased from 1977 to 1997 with nearly 5 units. The emission stayed consistent till the next 10 years.
United Kingdom experienced a downfall of their CO2 emission from nearly 11 units to 9 units from 1967 to 2010. Whereas, Sweden faced a different pattern of emission. It increased the emission from nearly 8 units to 10 units in 1977 which is their highest and suddenly emissions reduced to 7 units in 1987 and gradually reduced till 2007 with 5 units. In 2007, both Sweden and Portugal emit the same amount of CO2 with nearly 5 units.
