More Evidence Identifies China as The Source of Mysterious Ozone-Destroying Emissions
For years, a mystery puzzled environmental scientists. The world had banned the use of many ozone-depleting compounds in 2010. So why were global emission levels [DOI: 10.1038/s41586-018-0106-2] [DX] still so high?
The picture started to clear up in June. That's when The New York Times published an investigation into the issue. China, the paper claimed, was to blame for these mystery emissions. Now it turns out the paper was probably right to point a finger.
In a paper [open, DOI: 10.1029/2018GL079500] [DX] published recently in the journal Geophysical Research Letters, an international team of researchers confirms that eastern China is the source of at least half of the 40,000 tonnes of carbon tetrachloride emissions currently entering the atmosphere each year. They figured this out using a combination of ground-based and airborne atmospheric concentration data from near the Korean peninsula.

Greenhouse gas?
Do you mean the most important greenhouse gas, water? Because I think you'll find that the Amazon river is the largest emission of water by a single country. Of course, that is not in vapor form and even if it was it would be dwarfed by the water vapor coming off the oceans.
