carbon dioxide emissions
The line chart demonstrates the amount of carbon dioxide that each person released in four different countries from 1967 to 2007.
Overall, as can be seen from the chart, the emission of carbon dioxide of the two nations Italy and Portugal witnessed an upward trend while the figure for the United Kingdom and Sweden showed a decline over the period shown. In addition, at the beginning of the period, the United Kingdom was the highest country to produce the emission of carbon, and this was still true for the final year of this stage.
Looking at the chart in more detail, it is clear that people in the United Kingdom emitted the most with over 10 metric tonnes of carbon dioxide in 1967. Following up were Sweden, Italy with 8.3 and 4.1 metric tonnes in the given order. Portugal, on the other hand was the country that witnessed the lowest data for the first year of the chart. After 30 years from 1967 to 1997, these data changed. The figure for the United Kingdom decreased steadily by nearly 2 metric tonnes in 1997, compared to the fluctuating increases of Italy and Portugal which were at least twofold higher than it was at the beginning.
At the end of the period, the amount of carbon dioxide that Italian and Portuguese released expected to be the most changes during the time. They continued to increase after the year of 1997 until 2007. One noticeable difference was that the United Kingdom was still the highest one after 40 years despite experiencing a steady decrease. Beginning with over 8 metric tonnes, Sweden reached a peak at 10 in 1997 and then significantly declined until it reached the equal figure to Portugal at nearly 6 metric tonnes.
