Project products


The project is developing a number of useful and versatile tools targeted at policymakers, civil society and educators and experts:

The Integrated Assessment Model (IAM) “Within Limits IAM” (WILIAM) in Vensim and in open-acess through its Python version (pywiliam).

A Model Analyser that harnesses an easy-to-use graphical interface that allows policymakers to exploit the models without the need for programming skills.

A Model Explorer that enables non-experts to take a tour of the WILIAM model and to run through different scenarios.

A database that contains the results of projections of the most relevant variables and discloses details on each of the scenarios used.


The Global Sustainability Crossroads II Game in which the player’s mission is to find solutions for a set of environmental and societal challenges.
