Taxes are a more effective method of controlling pollution than are environmental standards because:

A) standards allow greater flexibility.
B) standards require less information.
C) standards never require the efficient level of output.
D) taxes encourage reducing pollution at the lowest possible cost.

Environmental Standards

Flexibility
