What is the most polluted country in the world?

“The cumulative perspective shows that in some countries, even those that emit many greenhouse gases bear a relatively small responsibility for climate change compared to historically large emissions,” the report says.

What country emits the most carbon dioxide today?

China is the largest emitter of carbon dioxide into the atmosphere today. According to Our World, based on the Global Carbon Project, in the data, in 2020 alone, China emitted 10.67 billion tons of carbon dioxide, nearly 30% of global emissions. In second place comes the United States, with 4.710 million tons of carbon dioxide emitted.

The third place for the European Union member states is 2,600 million tons, and the fourth place is India with 2,400 trillion tons, representing 7% of the total emissions.

The country with the highest emissions per inhabitant

Here, the list is completely different. The largest source of carbon dioxide emissions per capita is Qatar, emitting 37.02 tons per capita. New Caledonia, Mongolia, Trinidad and Tobago and Brunei are in the top five.

On this list, the United States is in 14th place with 14.24 tons of emissions per capita. China ranks 14th, with nearly half of emissions per capita. India ranks 131st in this ranking, thanks to its huge population.
