The Climate Framework for Uncertainty, Negotiation and Distribution (FUND) is a so-called integrated assessment model of climate change. FUND was originally set-up to study the role of international capital transfers in climate policy, but it soon evolved into a test-bed for studying impacts of climate change in a dynamic context, and it is now often used to perform cost-benefit and cost-effectiveness analyses of greenhouse gas emission reduction policies, to study equity of climate change and climate policy, and to support game-theoretic investigations into international environmental agreements.
FUND links scenarios and simple models of population, technology, economics, emissions, atmospheric chemistry, climate, sea level, and impacts. Together, these elements describe not-implausible futures. The model runs in time-steps of one year from 1950 to 2300, and distinguishes 16 major world regions.

FUND further includes the option to reduce emissions of industrial carbon dioxide. Reductions can be set by the user, or calculated so as to meet certain criteria set by the user.
An integrated assessment model, FUND is used to advice policymakers about proper and not-so-proper strategies. The model, however, always reflects its developer's world views. It is therefore regularly contrary to the rhetoric of politicians, and occasionally politically incorrect.
It is the developer's firm belief that most researchers should be locked away in an ivory tower. Models are often quite useless in unexperienced hands, and sometimes misleading. No one is smart enough to master in a short period what took someone else years to develop. Not-understood models are irrelevant, half-understood models treacherous, and mis-understood models dangerous.
Therefore, FUND does not have a pretty interface, and you will have to make to real effort to let it do something, let alone to let it do something new. If you want to give it a try, you can download selected versions of the model. You will need TurboPascal 7.0 for DOS to operate version 2.9 and below. This programme is no longer on the market, but you can purchase Delphi by Borland instead. For version 3.0-3.4, you need MS Visual Studio 2008 and Oxygene/Chrome/Prism.
For version 3.5 and higher you can run FUND with the free Visual C# Express Edition.
Descriptions and applications of the model can be found in the publications listed below.
FUND was originally developed by Richard Tol. It is now co-developed by David Anthoff and Richard Tol. FUND does not have an institutional home.
FUND would not have existed without the generous financial support by the Netherlands National Research Programme on Global Air Pollution and Climate Change,various research programmes of the European Commission, Directorate-General XII, the National Science Foundation through its support for the Center for Integrated Study of the Human Dimensions of Global Change, the Michael Otto Foundation, the Princeton Environmental Institute, and the Electric Power Research Institute.
