Final answer:
One advantage of environmental taxes is that firms that can reduce pollution cheaply and easily will do so to minimize their pollution taxes. The pollution tax also eliminates favoritism and loopholes for politically well-connected producers. Carbon taxes are an example of a pollution tax.
Step-by-step explanation:
One advantage of environmental taxes is that firms that can reduce pollution cheaply and easily will do so to minimize their pollution taxes, while firms that will incur high costs for reducing pollution will end up paying the pollution tax instead. This creates an incentive for companies to find the least expensive technologies for reducing pollution. Another advantage is that if the pollution tax applies to every source of pollution, there are no special favoritism or loopholes for politically well-connected producers. A global example of a pollution tax is carbon taxes that directly tax carbon dioxide.
