Which country has the most carbon emissions?

People's Republic of China

Explanation:

China is a country that has experienced an incredible development in the past few decades. The development of this country also meant that the consumption and usage of energy has grown significantly as well. The United States were the leading country when it came to carbon emissions for around a century, but China overtook them by a storm, to a point that at the present this country alone is responsible for over 27% of the total carbon emissions in the world. The reason for such high emissions of carbon is not just the big development of the industry, but also what that industry uses for producing energy. The majority of the energy used is from fossil fuels, with the coal still being heavily used, and the oil usage being constantly on the rise as well. Unlike lot of developed countries, China doesn't seem to put a lot of effort in more environment friendly energy production and usage as it doesn't want to experience stagnation in its economical development.
