Webinar: GACMO 2.0 – for enhanced climate action

This webinar presents the new version of the GACMO emissions projections tool for strengthening global climate policy and ambition

15 February, 2024 13:00 - 15 February, 2024 14:00

An upgraded version of the Greenhouse Gas Abatement Cost Model (GACMO) is now available, supporting informed decision-making on climate change – addressing the climate crisis and reducing greenhouse gas emissions.

The GACMO tool can be downloaded here.

This webinar will delve in to how GACMO 2.0 can provide countries with a clear understanding of the implications of their climate actions to enact meaningful change and contribute to global emissions reduction goals.

The new GACMO version introduces a more user-friendly interface with an enhanced step-by-step design, making it easier to navigate the complexities of emissions reductions and chart future emissions pathways.

Using GACMO provides valuable inputs for preparing and updating NDCs and to prepare national climate plans and long-term strategies as well as international transparency reports such as the Biennial Transparency Reports.
