What is Marginal Abatement Cost Curve (MACC)?
The Marginal Abatement Cost Curve (MACC) illustrates the potential emissions reduction and corresponding costs of various mitigation options relative to a baseline over a specified period. Determining the baseline is critical and relies on data and assumptions about future projections. MACCs can assess strategies for organizations, countries, or sectors, though creating economy-wide or global MACCs is complex due to diverse marginal abatement costs across sectors and countries.
