Marginal Abatement Cost Curve

Visualise the impact and compare the cost of different policy options. For example, you can illustrate the cost-effectiveness of measures to reduce greenhouse gas (GHG) emissions by plotting the marginal cost per tonne of CO₂-equivalent avoided against the volume of abatement each measure can deliver. Marginal abatement cost curves can be used for: • Policy prioritisation: identifying which options should be implemented first (typically those with the lowest or negative costs). • Scenario modelling: estimating total abatement potential at various carbon price levels. • Budget allocation: guiding public or private investments towards the most cost-efficient decarbonisation pathways. • Environmental planning: informing Nationally Determined Contributions (NDCs), long-term climate policy strategies, or sectoral decarbonisation roadmaps.
