Question

Under current WTO rules, a country can adopt:

		any environmental standard it chooses, even if it discriminates against foreign producers.
		any environmental standard it chooses as long as it does not discriminate against foreign producers.
		only WTO-approved environmental standards.
		only the same environmental standards as its immediate geographic neighbors.

Answer 1

Option 2

any environmental standard it chooses as long as it does not discriminate against foreign producers

the WTO rules protect the right of foreign producers concerning the international trades, and that monitor regulary so a country can adopt any environmental standard it chooses as long as it does not discriminate against foreign producers, but it should not discriminate any producer because of it.

The environmental goal or targets are constrained only in the border of the country and the country can not ban the import of a good on the basis of domestic standards.
