The pie chart compares the proportion of carbon dioxide emissions by six major countries and the remaining part of the world in the year 2015, whereas the bar graph shows the CO₂ emissions per capita measured in metric tonnes in the same year.
Overall, it is evident that China was responsible for the largest percentage of CO₂ emissions, while Germany made up the smallest share. It is notable that the big nations responsible for global CO₂ emissions were not in the list for per capita emissions, where Saudi Arabia dominated the figures.
In terms of global CO₂ emissions, China accounted for almost one-third of total CO₂ pollution, followed by the USA at 17%. On the other hand, Russia and India contributed 5% and 7% of total CO₂ emissions globally, respectively. The proportion for Japan was 4%, and Germany made up 2% of global CO₂ emissions, which was the lowest amongst all. Finally, the remaining nations accounted for 34% of the total emissions.
In regards to per capita emissions, Saudi Arabia produced 16 metric tonnes – the highest among all. United States, Australia, and Canada all produced around 15 metric tonnes of carbon dioxide. Similarly, South Korea was responsible for production of 12 metric tonnes. By contrast, Russia generated the lowest CO₂ with only 10 metric tonnes.
