Overview of World CO2 Emission

Reviewing the historical emission, we could locate the 10 countries producing the most carbon dioxide in the past. If a causal relationship exists between the emission and GDP, it could be fair to argue that countries with higher GDP have the responsibility to contribute more and providing support to the less developed regions. However, data shows us that some countries, e.g., Estonia and Russia, experience high emission without leading economy.

Comparison within G7

The G7 is an informal grouping of seven of the world’s advanced economies. Comparing the emission of these seven countries give us an overview of the developed world.

Comparison within Low-Income Developing Countries

The scheme is quite different in the developing world. As developing economy, countries like Nigeria and Vietnam release excessive amount of CO2, with an observable tendency to increase during the recent three years. At the same time, Kenya and other countries accumulates less than 5000 tons CO2.

The absolute amount of CO2 each resident produces in the developing countries is significantly lower than that in advanced economy.
