Applying Market-Oriented Environmental Tools

Applying Market-Oriented Environmental Tools

Market-oriented environmental policies are a tool kit. Specific policy tools will work better in some situations than in others. For example, marketable permits work best when a few dozen or a few hundred parties are highly interested in trading, as in the cases of oil refineries that trade lead permits or electrical utilities that trade sulfur dioxide permits. However, for cases in which millions of users emit small amounts of pollution—such as emissions from car engines or unrecycled soda cans—and have no strong interest in trading, pollution charges will typically offer a better choice. Market-oriented environmental tools can also be combined. Marketable permits can be viewed as a form of improved property rights. Or the government could combine marketable permits with a pollution tax on any emissions not covered by a permit.
