What country causes the most global warming pollution?

Answer 1

The politically correct answer is all countries are responsible for GHG emissions. However the top contributors of carbon dioxide are:

World total: 27 Billion tonnes/ year

USA : 6 Billion tonnes/year (22.2%)

China: 5 Billion tonnes/year (18.4 %)

European Union: 4 Billion tonnes/year (14.7%)

All the rest of the world (+150 countries) produces the other 50% of the carbon dioxide

Answer 3

Per capita, the US is one of the worst offenders. China's CO2 output only recently eclipsed that of the US, but they have a long way to go yet to match the US per capita emissions.

There are a few smaller countries that are worse, per capita, than the US, but their total emissions are not substantial as their populations remain fairly small.

Answer 4

Until recently the United States was by far the largest emitter of greenhouse gasses. China only recently wrestled away that dubious distinction.

Answer 5

China emits the most emissions annually. The USA historically has emitted the most overall.
