Marginal Abatement Cost Tool (MACTool)
The Marginal Abatement Cost Tool (MACTool) is an Excel-based tool which provides an easy way for building marginal abatement cost curves, and for calculating break-even carbon prices. MACTool helps policymakers compare the costs and benefits of emission reduction options that can be used to build low-carbon scenarios at a national or sub-national level. It provides a cost-benefit comparison of these options and an estimate of the incentives needed to make these options attractive for the private sector by calculating break-even carbon prices. It also enables governments to assess the total investment needed to shift towards low carbon growth.
