What does abatement mean in economics?

Abatement costs refer to expenditures which reduce the direct pressures on natural assets (for example from air emissions or waste disposal).

How do you interpret a marginal abatement cost curve?

How to read a Marginal Abatement Cost curve. The height of the vertical or y-axis of the graph represents the cost of each of the potential energy efficiency projects, while the width of the horizontal or x-axis represents the total GHG abatement potential for each option. The fattest block delivers the most abatement.

What does the marginal abatement curve plot?

An typical example of a Marginal Abatement Cost Curve (MACC). MACCs plot cumulative emissions reductions from successive mitigation options (e.g. tonnes of GHGs avoided in CO2e) against the incremental cost per unit of emission reduction (e.g. $/T CO2e).

Why is the marginal abatement cost curve upward-sloping?

MAC curve reflects the additional costs of reducing the last unit of carbon and is upward-sloping: i.e. marginal costs rise with the increase of the abatement effort. Figure 3. 1 shows a stylised Marginal Abatement Cost curve.

What is marginal abatement costs in economics?

Abatement cost is the cost of reducing environmental negatives such as pollution. Marginal cost is an economic concept that measures the cost of an additional unit. The marginal abatement cost, in general, measures the cost of reducing one more unit of pollution.

Why is the marginal abatement cost curve downward sloping?

The upward-sloping MB curve means that any additional ton (unit) of abatement generates smaller additional benefit than the one that preceded it. The downward-sloping MC curve means that any additional ton (unit) of abatement costs more than the one that preceded it.

When the marginal cost curve is above the average total cost curve?


When the marginal cost curve is above an average cost curve the average curve is rising. When the marginal costs curve is below an average curve the average curve is falling. This relation holds regardless of whether the marginal curve is rising or falling.

How do you calculate abatement cost?

To work out the total abatement costs under a uniform standard, we just need to compute the area of the two triangles that capture the total abatement costs of each firm. The abatement cost of the type I firm is (4*4*0.5) = 8. The abatement cost of the type II firm is (2*4*0.5) = 4.

How is a MAC curve built?

The MAC curve methodology involves initially a compilation of a city’s climate mitigation policies and programs, followed by a quantitative analysis of the technical and economic dimensions of each of the mitigation measures considered.

What is the relationship between marginal and total abatement costs?

units of pollution, while marginal abatement costs are the cost of abating each unit of pollution. Total damages are and total abatement costs are represented by the areas under the marginal curves. Total social costs are the sum of total damages and total abatement costs for a given level of emissions.

What is Mac and MD?

MD can be interpreted as the marginal benefit of reducing emissions (damages saved), and MAC is the marginal cost of reducing emissions. That is, they are social marginal benefits and social marginal costs of reducing pollution.

What can be inferred from a typical marginal abatement cost curve MACC )?

A marginal abatement cost curve – or MACC – is simple to understand when you break it down. In this context, ‘abatement’ means ‘reducing’. A MACC presents the costs or savings expected from different opportunities, alongside the potential volume of emissions that could be reduced if implemented.
