GACMO 2.0: New tool for enhanced climate action

UNEP Copenhagen Climate Centre has launched the GACMO 2.0, an enhanced tool strengthening global climate policy

An upgraded version of the Greenhouse Gas Abatement Cost Model (GACMO) is now available, enabling informed decision-making on climate change mitigation.

Providing countries with a clear understanding of the implications of their climate mitigation actions, the new GACMO version allows countries to enact meaningful change and contribute to global emissions reductions.

The new version of GACMO can be downloaded freely here.

Transparent climate action

Data on current and future greenhouse gas emissions is a prerequisite for countries to inform political decisions concerning climate action. It is also the foundation for transparent and credible climate mitigation action at national and global levels.

GACMO is a greenhouse gas emissions projections tool that has been updated and refined by the UNEP Copenhagen Climate Centre over two decades, equipping countries with a tool for navigating the complexities of emissions reductions and chart future emissions pathways.

This new version has been developed with the support of the Initiative for Climate Action Transparency (ICAT).

User friendly scenario analysis for mitigation action, NDCs and BTRs

The new version, GACMO 2.0, adheres to the well-established methodological approach of the previous version while introducing a more user-friendly interface. It has an enhanced step-by-step design, ensuring that users, regardless of their expertise, can harness the tool's power. It also offers new options for presenting results so that they can be used to inform policymakers.

Additionally, detailed guidance and two video tutorials accompany the tool, providing comprehensive support to users.

GACMO has been an instrumental tool in enabling countries to conduct rapid, yet precise scenario analysis of how different mitigation options would impact greenhouse gas emissions. This provides valuable inputs for preparing and updating NDCs by identifying NDC targets for emissions reductions and by providing assessments of future emissions in different climate action scenarios.

GACMO can also be used to support the preparation of national climate plans and long-term strategies as well as international transparency reports such as the Biennial Transparency Reports outlined in the Paris Agreement.

By offering valuable insights into how various mitigation actions influence emissions, GACMO 2.0 can be an indispensable resource in the quest for sustainable and impactful climate action.

Highlights:

Climate Transparency Platform

The Climate Transparency Platform  is a one-stop shop for climate transparency , covering everything related to the Enhanced Transparency Framework of the Paris Agreement and the continued reporting under the UNFCCC.

It provides a global overview of transparency initiatives and developing countries transparency efforts, allowing users to stay up to date on the latest developments, events, and knowledge products, as well as get detailed information on any developing country, support provider and transparency projects. The platform allows for vivid exchange within the climate transparency community, both through a Community of Practice space with discussions on different transparency projects as well as ten Network Forums for peer-to-peer exchange and learning among countries. 

The platform also serves as space for coordination among transparency support providers, and for countries to directly request support to cover specific needs for transparency in all areas of the Enhanced Transparency Framework.

As well as providing updated overviews and a direct avenue for getting support, the Platform serves as a knowledge clearinghouse for climate transparency information containing everything from case studies to guidelines, offering a comprehensive and diverse range of knowledge products that can help build capacity and facilitate learning for policymakers, practitioners, and experts.  

The Climate Transparency Platform is part of the Capacity-building Initiative for Transparency - Global Support Programme (CBIT-GSP), a global transparency support project , funded by the Global Environment Facility (GEF), implemented by UNEP, and executed by the UNEP Copenhagen Climate Centre.

Climate Transparency and why it matters? 

In this informative explainer, we will explore the critical importance of climate transparency in today's world. The credibility of climate policies and implementation actions ultimately depends on a credible transparency system that can assess and report on their effectiveness.

Transparency at the national level is critical to building trust in the multilateral climate regime, while credible data and reporting on climate action informs on what does and does not deliver the expected results. Climate change is one of the most significant challenges facing humanity, and understanding its effects and the actions we must take to combat it.
