Climate Action Aggregation Tool

The Climate Action Aggregation Tool (CAAT) supports government experts, analysts and policymakers to identify, quantify and aggregate the impact of non-state and subnational actions. As a result, they can be integrated into mitigation targets, projections and scenarios in support of policy development, policy evaluation and target-setting. 

The tool distils the step-by-step process laid out in the ICAT Non-State and Subnational Action Guide. The tool was updated in 2024.

Uses and functionalities:

1. Better quantify the impact of region, city, and business emissions reduction efforts
2. Evaluate how they overlap with or complement national policies
3. Determine the impact of combined national and sub-national efforts for integration into more holistic target-setting
