25th march 2009 International workshop for experts & policymakers HOW CAN CLIMATE POLICY MODELS SHAPE REAL DECISIONS ?

Purpose of the workshop :

Ever since the first attempts to model GHG mitigation policies at the end of the 70s, an international industry for energy-economy-climate models has emerged. This model industry produces dozens of new scenarios and thousands of figures every year, a profusion of scientific material contrasting with the few truly new conclusions that can be drawn from them. This model industry has its producers, about fifty research teams worldwide working hard to handle increasingly complex models, and its final consumers, private and public decision-makers trying to make progress on global climate management.

This industry does enjoy flourishing activity and ongoing methodological advances, and has produced cost estimates for various levels of GHG emissions reductions, at various points in time, and under various policy frameworks. However, it must be admitted that the modeling community has yet to fulfill its potential to structure rationale in climate policy deliberations. Some attribute this shortfall to policymakers turning a blind eye to modeling results, sometimes because of distrust of the very wide range of published scenarios and policy cost figures. Others attribute it to economists using inappropriate assumptions in the models.

The post-2012 regime is approaching and there is urgent need for an open exchange of views between modelers and policymakers on modeling practices, the shortcomings of models and the extent of their legitimacy, the language employed in communications concerning models high in technical content, and upcoming challenges for the modeling community.

We thus propose a one-day workshop bringing together a small group of modelers and decision makers for an in-depth discussion on the above concerns, focusing in particular on the current state of modeling, ongoing developments, and the information that decision makers currently lack and need in order to push forward the climate agenda.

The workshop is organized by the IDDRI “ Institute for Sustainable Development and International Relations and the CIRED “ International Center for Environment and Development Research, and benefits from the support of the Ile-de-France region through R2DS - the Research Network for Sustainable Development.

Transversal themes that cut across the open-ended discussions throughout the workshop include :

- Pending methodological issues
- Translation problems between the language of modelers, the internal language within decision-making circles, and politically acceptable language with the general public.
