Environmental Results

This guide explains how to display and configure environmental results within the LEAP software, detailing the options for reporting individual effects, Global Warming Potential (GWP), and the territorial accounting approach used for emissions.

• Environmental effect results, including non-energy sector effects, are only accessible if the user enables "Energy Sector Effect Loadings" in the General: Settings: Scope & Scale screen. Results can be organized by branch, effect, fuel, scenario, year, and region.
• LEAP allows for the calculation of combined global warming potential (GWP) for greenhouse gases, measured in either Carbon (C) or Carbon Dioxide (CO2). Users can select time horizons of 20, 100, or 500 years, with default GWP factors based on the IPCC Second Assessment Report (ARII), though users can switch to factors from the first, second, third, or fourth IPCC assessment reports.
• Environmental loadings are available in four formats: Individual effects (standard physical units), Direct GHG Emissions at the point of emissions (20, 100, and 500-year GWP), Direct (Demand) plus Indirect (Transformation) GHG Emissions Allocated to Demand Branches (100-year GWP), and Indirect (Transformation) GHG Emissions Allocated to Demand Branches (100-year GWP). Only the first two formats are enabled by default.
• LEAP employs a territorial accounting approach for environmental results, aligning with IPCC and UNFCCC National GHG Emissions Inventory Guidelines. This method includes combustion and fugitive emissions occurring within the LEAP area boundaries—including those from energy sector operations for exported final fuels—but excludes emissions from primary fuels exported and consumed in other areas.
