English Abstract IMAGE 2 is an integrated assessment model for global
and regional climate change. The aim of the model is to simulate
scientifically and thoroughly the policy-relevant issues in climate change.
The model therefore simulates the whole cause-to-effect chain covering
emissions from energy and land use, biogeochemical cycles, atmospheric
chemistry, and circulation and impacts. IMAGE 2 consists of three major
components: the Energy-Industry System, the Terrestrial Environment System
and the Atmosphere & Oceans System. Interactions and feedbacks are modelled
explicitly. Improvements and new modules (e.g. TIMER, agricultural
economics model, land degradation, sulphate aerosols and sea-level rise) are
described and some tests and applications highlighted. The full
documentation of IMAGE 2.1 and its applications have been published in book
form and as a User Support System on a CD-ROM. This report is intended only
to summarise these publications, describing recent developments in working
towards the IMAGE 2.2.
