This guide explains the demand-driven logic used for transformation calculations within the LEAP framework, detailing how requirements flow from final demands to primary resources through a sequence of modules.

The document is a technical guide describing the functionality of the Tree Filter Toolbar within the LEAP software, explaining how users can filter model branches to improve productivity without affecting data or calculations.

This guide explains the dispatch rules used in the LEAP Transformation module when operating in simulation mode to determine how processes meet energy and power requirements.

This guide describes the 'Basic Parameters Screen' in the Low Emissions Analysis Platform (LEAP) software, detailing the settings used to configure the scope, scale, timeframes, and calculation methodologies for energy system modeling.

This guide lists the reserved words that cannot be used as branch, fuel, or region names in LEAP expressions and outlines the character and length requirements for naming LEAP branches.

This guide explains the 'Renewable Target' variable within a transformation analysis tool, which is used to set minimum percentage requirements for renewable fuel in optimization-based scenarios, such as Renewable Portfolio Standards (RPS).

This guide explains the 'Fraction of Scrapped Replaced (%)' variable within the LEAP software, which determines the proportion of scrapped devices that are immediately replaced by new sales.

The Technology and Environmental Database (TED), integrated within LEAP, provides comprehensive quantitative data on the technical characteristics, costs, and environmental impacts of approximately one thousand energy technologies to support analysts, particularly those in developing countries.

This fact sheet presents findings from a multi-country needs assessment conducted across Bangladesh, Cambodia, Nepal, and Thailand to inform the design of capacity-building programs for inclusive climate finance between 2023 and 2025.

This guide describes the use of expressions within the Low Emissions Analysis Platform (LEAP), explaining how mathematical formulae are used to specify variable values in the Analysis View for both historical data and future scenarios.

This guide from the Stockholm Environment Institute explains four methods for specifying capacity data within the Low Emissions Analysis Platform (LEAP) Transformation module, ranging from ignoring capacity limits to full least-cost optimization.

This guide explains how the Low Emissions Analysis Platform (LEAP) handles expression search in a scenario hierarchy featuring multiple inheritance, specifically when a mitigation scenario is composed of multiple sectoral packages.

This guide describes the open-source data services provided by the Stockholm Environment Institute for use in energy and environment models, detailing the REST web services and JSON format used to access datasets such as UN Population Prospects, World Development Indicators, IDEES, and IPCC Shared Socioeconomic Pathways.

This guide describes the different types of tree branches used in the LEAP modeling software, explaining their functions, icons, and the types of data they handle across Demand, Transformation, and Resource analyses.

This technical guide explains the 'Lookup' function, which determines a dependent value based on an independent variable reference using either linear interpolation or step-wise changes. It specifies that independent values must be listed in ascending order and provides a concrete example of calculating wind power capital costs based on installed capacity.

This guide explains how to enable and configure land-based resource analysis within the Low Emissions Analysis Platform (LEAP) software, detailing the necessary settings, data requirements, and the resulting changes to the software's interface.

This guide from the Stockholm Environment Institute explains how to input yield, land area, and woodfuel accessibility data into a resource analysis tool, detailing the mathematical calculation of the overall access fraction based on location, tenure, and management factors.

This guide explains the mathematical logic and sequence LEAP uses to calculate endogenous capacity expansion, focusing on how the system determines the amount of capacity needed to meet peak power requirements and maintain a planning reserve margin.

The SUMERNET PLUS fact sheet describes a transboundary programme running from July 2025 to December 2029, funded by the Swedish Government. The initiative aims to enhance climate resilience in the Mekong Region through scientifically robust research, inclusive policy development, and the adoption of sustainable practices by the private sector.

This briefing from the Stockholm Environment Institute (SEI) outlines a call for events designed to mobilize knowledge from women environmental human rights defenders (EHRDs). The initiative focuses on the intersectional discrimination faced by women EHRDs and seeks to showcase how their empowerment and mobilization can transform power imbalances that drive gender and social inequality, particularly within an Asian context.
