The concept of transformational change recognizes the fundamental, radical changes in economic activity required to meet the global goals for climate and sustainable development. Transformational change refers to system change, rather than singular, stand-alone development, and involves multiple actors at multiple levels of society.

The Transformational Change Toolkit is a set of easy-to-use tools that support policymakers and other users to assess the potential transformational impacts of a wide range of climate policies, actions, and projects, covering both mitigation and adaptation. These are referred to as interventions in the toolkit. It is a free-to-use, web-based software.

The toolkit is composed of the following tools:

• The carbon market tool: assesses the transformational impact of interventions with a carbon market component, i.e., interventions where emission reductions may be partially or totally traded.
• The investment tool: assesses the transformational impact of investments by funds or private companies.
• The general assessment tool: assesses the transformational impact of interventions that do not fall under two tools above. 
• The portfolio tool: aggregates and compares the transformational impacts of several single interventions grouped under a portfolio. Such a portfolio may be artificial or correspond to an existing package of interventions, such as a country’s nationally determined contributions.

Combine with the ICAT Transformational Change Methodology:

The toolkit facilitates the application of the ICAT Transformational Change Methodology, which defines transformational change for greenhouse gas mitigation and provides a stepwise approach to determining the extent to which a policy is truly transformational.
