   When automobiles that are now new become older, they will, because of a design change, cause less air pollution

   This actually feels like it supports the argument, as it suggests that later models of cars, even as they age, will pollute less than the current older models, bolstering the idea that air pollution will be reduced in the future. It's technically irrelevant since the conclusion is only about what air pollution will be contributed by the older cars, not overall air pollution.

   Even if all the older automobiles in the United States were retired from service, air pollution from United States automobiles could still increase if

   This describes a scenario where global air pollution could increase, but that increase would have nothing to do with pollution contributed by older U.S. cars, which is what the conclusion is talking about. In fact this answer is basically guaranteeing that all the older U.S. cars will be out of service, so by definition they should be contributing less pollution than before.
