The given chart illustrates the amount of carbon dioxide emitted into the air by different income classes between 1990 and 2000. The pie chart illustrates the percentage of the global population by different financial groups, including high-, middle-, and low-income, in 2000.
Overall, in the first chart can be seen that people from the middle class recorded the highest carbon dioxide emissions; second came high-income individuals. In the second chart, affluent individuals showed the highest percentage of the global population, then the middle class ranked second, and the low class ranked third.
Focusing on carbon dioxide emissions first, in 1990, wealthy individuals released 13 units of carbon dioxide, while the middle-income group showed 15 units. Underprivileged communities released into atmosphere only 1. In the next decade, the wealthy ones presented 13 units, just over what it was in 1990. But middle ones increased significantly to 22 units, and impoverished people rose only to 2 units.
By contrast, by 2000, the upper class started with 84%, taking the top. Then, representatives of the middle-income community accounted for 34%. Finally, representatives of the low-capital came last with 18% of the world population.
