We consider two delinking policies. One differentiates banked permits by origin, the other treats banked permits the same. We describe the price behavior and relative cost-effectiveness of each policy. Treating permits differently generally leads to higher costs, and may lead to price divergence, even with only speculation about delinking.

In order to increase the cost-effectiveness, liquidity, and stability of these markets, the entities that control them may choose to link programs together in a framework that allows permits to be unilaterally or bilaterally accepted across joined systems... read more on Common resources
