Key Concepts

Pollution Cap

The pollution cap is the total allowable amount of pollution established under a marketable permits system. It directly determines the ceiling level of pollution in the economy. A zero pollution outcome would require setting the cap at zero, but this is typically impractical because it would eliminate the possibility for any pollution-related economic activity and undermine the purpose of using market mechanisms to achieve a balance between environmental goals and economic performance.

Marketable Permits System

A marketable permits system, often known as cap-and-trade, is an environmental policy instrument where a governing body sets a cap on the total amount of pollution allowed and issues permits corresponding to that limit. These permits can be bought and sold by polluters, enabling firms with lower abatement costs to sell excess permits to those facing higher costs of reducing emissions. This system is designed to achieve pollution reduction targets in an economically efficient manner while allowing flexibility in how individual firms meet their targets.

Economic Trade-offs and Efficiency

The design of marketable permits systems inherently involves trade-offs between environmental quality and economic costs. Since the system is structured to minimize overall abatement costs by allowing flexibility and trading, it establishes a nonzero level of pollution that meets the cap rather than eliminating pollution entirely. Achieving zero pollution would forgo these economic efficiencies and is generally not pursued because it could impose disproportionately high costs on the economy without significant marginal benefits in terms of environmental improvement.
