Emissions from power plants are often out in the countryside not adding to city smog.
Really? If we're getting pollution from Asian power plants in the US, do you think pollution generated a few miles out of town isn't impacting nearby cities?

A growing amount of pollution from China and the rest of Asia is being carried over the Pacific and dumped on the west coast of the US.
The impact is a fairly regular number of air pollution violations in US cities, directly attributed to pollution that originated in Asia.
Asia burns a lot of coal, and Chinese coal in particular contains a high amount of mercury, making the country the largest source of chemical in the world.
Although there are ongoing UN negotiations on reducing mercury emissions, expectations that China will be willing to invest in technology, or be given help in getting technology, to reduce atmospheric emissions of mercury are low.
Ironically, the US could also be contributing to its own mercury pollution too if it pushes through plans to scale up the export of coal to China.
US coal is already being exported to China through Canada. Just south of the west coast port city of Vancouver, the Westshore Coal Terminal ships 22 million tonnes of coal a year, of which 59% goes to China. There are plans to build dozens of new terminals in the states of Washington and Oregon, on the west coast of the US, and export 150 million tonnes of coal a year to Asia.
We ship coal to China, they burn it and we get the pollution back.
