GHG Abatement Cost MOdel (GACMO)

 GHG Abatement Cost MOdel (GACMO)

The GACMO (Greenhouse Gas Abatement Cost Model) is a greenhouse gas emissions projections tool developed over more than twenty years by the UNEP Copenhagen Climate Centre.
It allows countries to carry out rapid but accurate scenario analysis of how a variety of mitigation options impact emissions, thereby increasing transparency and contributing to informed decision making.

The tool can provide valuable input for preparing and updating NDCs by identifying NDC targets for emissions reductions and by providing assessments of future emissions in different climate action scenarios.

It can also be used to prepare biennial transparency reports (BTRs) under the Paris Agreement.

A new version of GACMO has been developed with support from ICAT and is now available. The new version follows the same methodological approach, but has a user-friendly step-by-step improved interface, and comes with detailed guidance and two video tutorials.
