Marginal Abatement Cost Curve (MACC-McKinsey)

The McKinsey MACC tool provides information on the abatement potential, cost and investment of over 200 mitigation options with the possibility of various levels of granularity. The opportunities for emission reductions included in the MAC-curve take into account the investments and associated operating costs. It presents how much emissions can be abated per specific option and the associated amount of money it will cost or save you per tCO2e. Developing the MAC-curve is done in projects with McKinsey with a high number of local experts and stakeholders to account for local specifities. The projects include substantial awareness raising and capacity building on mitigation. McKinsey has also developed the Climate Desk tool for the global GHG abatement cost curve, which users can access a license for. Over 100 academics and other experts have been granted a free license to the tool.
