The line graph depicts how much carbon dioxide was emitted per person in 4 different countries (the United Kingdom, Sweden, Italy, and Portugal) from 1967 to 2007. Units are measured in metric tonnes. Overall, the British were the nation with the highest carbon dioxide production throughout the given period.
To begin with, the amount of Co2 emitted in the United Kingdom and Sweden decreased in the forty-year period. In 1967, the UK produced around 11 metric tonnes of Co2 which gradually reduced to less than 9 metric tonnes in 2007. Although this amount had a downward trend throughout the period in question, the UK generated the highest amount of Co2 among the other countries. Similarly, Co2 emissions in Sweden started at less than 9 metric tonnes; it peaked at around 10 metric tonnes in 1977 before, it sharply declined to roughly 5 metric tonnes in the final year.
On the other hand, different picture emerged for Italy and Portugal, with an increase in Co2 emissions during the given period. Both countries, followed almost the same pattern with a steady increase, prior to leveling off from 1997 to 2007.Their starting point was close to 4 metric tonnes and approximately 1 metric tonnes Co2 emissions for Italy and Portugal respectively. In 1997, at around 8 co2 emissions for Italy and 5 co2 emissions for Portugal were the highest level of co2 production which remained almost stable until the end of the period.
