Scenarios

The document explains the functionality of the LEAP Scenario Manager, focusing on the hierarchical structure of expression inheritance to minimize data entry. It details how to edit scenario properties, such as Global Warming Potential (GWP) values and Marginal Abatement Cost Curve (MACC) report inclusion, and describes the tools available for adding, deleting, and duplicating scenarios.

• LEAP utilizes a hierarchical scenario structure based on expression inheritance, allowing users to enter data only in a scenario if it differs from its parent or ancestor scenario, which reduces data entry requirements.
• The Scenario Manager allows users to override default global warming potential (GWP) values for greenhouse gas emissions calculations, including the ability to select values from any of the five IPCC assessment reports (ARs) for sensitivity calculations.
• Users can designate specific scenarios for inclusion in Marginal Abatement Costs Curve (MACC) summary reports, though the guide recommends including only scenarios representing individual policies and measures rather than integrated combinations.
• The software provides a 'sensitivity' setting that allows expressions within a specific scenario to override the values typically shared from the Current Accounts scenario.
