The chart illustrates the average carbon dioxide (CO2) emissions for individuals in the United Kingdom, Sweden, Italy and Portugal between 1967 and 2007.
Overall, the United Kingdom’s waste from CO2 decreased over time. Sweden’s line of CO2 emissions fluctuated year over year, but in the end, it remained stable and downgraded. Italy and Portugal went up, and CO2 expanded during this period.
The United Kingdom’s CO2 emissions in 1967 were 10.9 CO2 emissions in metric tonnes, but this reached its lowest in 2007 touching the 9 CO2 emissions metric tonnes mark. On the other hand, Italy’s CO2 disposals in 1967 were 4.2 and it was one of the lowest countries in this chart. However, this changed in 2007 and reached its highest peak which was 7.8 CO2 emissions in metric tonnes, making Italy the second highest country on this list, equally, Portugal also went on the same path as Italy, because in 1967 Portugal’s CO2 emissions were 1.6 CO2 emissions metric tonnes and went rapidly hitting the 4.6 CO2 emissions in metric tonnes in 2007.
In contrast to that, Sweden’s line changed a lot between 1967 and 2007, in 1967 Sweden’s wastes were 8.5 CO2 emissions in metric tonnes, raised to 10.2 CO2 emissions in metric tonnes in 1977, then began to decrease in 1987 by hitting the 7 CO2 emission in metric tonnes, crossing by 6 CO2 emission in metric tonnes in 1997, and reached its lowest number in 2007 which is 5.2 CO2 emissions in metric tonnes.
