Two countries, A and B, have to make a decision on the targets of emission permits (one emissions permit is considered equivalent to one metric ton of carbon dioxide (C02) emissions; also referred to as carbon credits, Kyoto units, assigned amount units, and Certified Emission Reduction units (CERD that they will impose for their national industries, given the EU wide cap on emissions.
