The bar chart compares the volume of CO2 emissions from energy production in five different nations – China, India, Russia, Japan, and the US – over a decade, from 2000 to 2010.
Overall, China and the US were the most significant contributors to CO2 emissions throughout the period. While China witnessed a dramatic increase in its emissions, the US saw a noticeable decline. The emissions from the other three countries remained relatively stable but were substantially lower.
In 2000, the US was the largest emitter, releasing approximately 12 units of CO2, compared to China’s 10 units. Over the following decade, this trend reversed dramatically. China’s emissions rose sharply to just under 14 units by 2010, making it the world’s leading polluter from energy production. Conversely, the USA’s emissions fell significantly to about 8 units.
The remaining countries had considerably lower emission levels. Both India and Russia started at around 4 units in 2000 and experienced minimal change, with India’s figure rising slightly and Russia’s remaining almost static. Japan’s emissions, which began at approximately 6 units, also remained stable over the ten-year period.
