Using Different IBC Methods in Different Scenarios

This guide explains how to configure and vary Integrated Benefits Calculator (IBC) methods within LEAP scenarios, specifically regarding health impact functions, particulate matter scaling, and background emission scenarios.

• Users can control the health impact relative risk function by creating a Key Assumption Branch at 'Key\IBC Settings\Relative Risk Version' and assigning an integer value. Supported versions include Global Burden of Disease 2010 (0), 2015 (1), and 2019 (2).
• Particulate matter (PM) scaling is managed via the 'Key\IBC Settings\PM Scaling' branch with two options: 'No Scaling' (0), which calculates concentrations directly from LEAP emissions for any base year, and a scaling approach based on van Donkelaar, 2016 (1). The latter requires a LEAP base year of 2010 and complete accounting of all relevant national particulate-forming emissions.
• The background Rest of World emission scenarios are controlled through the 'Key\IBC Settings\ECLIPSE' branch, which allows users to select between IIASA ECLIPSE scenario versions 5 or 6.
