Abatement

Reduction in amount, degree, or intensity of an activity, particularly in reference to emissions and pollutants.

In one sentence

Abatement is any action that reduces pollution (emissions or other environmental damage), either by changing production technology or changing behavior.

What is being reduced

Abatement can refer to reducing:

  • the flow of emissions (e.g., CO2 per year),
  • the intensity of pollution (e.g., CO2 per unit of output),
  • or the stock of pollutants (e.g., cleaning a contaminated site).

Two practical types

  • Technical abatement: cleaner inputs and processes (filters, scrubbers, electrification, process redesign).
  • Behavioral abatement: changes in consumption or operations (driving less, energy conservation, shifting demand to low-carbon options).

How economists think about it (margins)

The central idea is that abatement has rising marginal costs: the first reductions are usually cheap, and deeper cuts are more expensive. This leads to the marginal abatement cost (MAC) curve.

Policy design often targets least-cost abatement by equalizing MAC across sources.

    flowchart TD
	  A["Pollution target set"] --> B{"How to reach it at lowest cost?"}
	  B --> C["Let low-MAC sources abate more"]
	  B --> D["Let high-MAC sources abate less"]
	  C --> E["Equalize MAC across sources<br/>(via tax or permit price)"]
	  D --> E
	  E --> F["Same total abatement<br/>at minimum total cost"]

Common policy instruments

  • Emissions tax (or carbon tax): firms abate until MAC equals the tax.
  • Cap-and-trade: permit price equalizes MAC across firms.
  • Standards (technology/performance): can work, but may be more expensive if they prevent trading/adjustment.
  • Abatement Cost: The expense incurred in reducing pollutant emissions.
  • Emission Trading: A market-based approach to control pollution by providing economic incentives.
  • Carbon Tax: A tax on fossil fuels aimed at reducing carbon dioxide emissions.
