Logistic Substitution model II (LSM2)

The "IIASA Logistic Substitution Model II" (LSM2) is a software tool to estimate the parameters of technological growth and substitution processes. Applications include marketing research, scenario development, historical transition analyses, as well as meta-analysis across many individual technologies.

Applied Justice Taxonomy and Assessment Framework (AJUST)

The AJUST Framework comprehensively outlines justice in its multiple aspects with the aim to facilitate justice assessment across diverse research and policy contexts. It is meant to be accessible across disciplines, powerful in terms of capacity to express a variety of justice ideas, and modular so researchers can select and deploy the aspects that are most appropriate or useful.

ENGAGE Scenario Explorer

The Horizon 2020 project ENGAGE quantifies avoided climate change impacts through analysis of the exposure and associated costs for individual sectors and regions to climate change at different levels of and timing for global peak temperature. A particular focus is placed on quantifying the benefits (or trade-offs) of climate policies on biodiversity, food, poverty, water, air quality, health, and employment, particularly for vulnerable populations.
