Long run scenarios of transition pathways


Global scenarios scenarios produced by Imaclim asses international coordination regimes of reduction efforts and stabilization trajectories of GHG concentrations.


Imaclim-R computed 53 of the scenarios in the AR5 database, and 15 different journal articles based on Imaclim-R results are mentioned in the chapters of the AR5 report on mitigation. This presence of Imaclim-R in the AR5 stems from the participation to three modeling comparison projects - RECIPE, the EU-FP7 AMPERE project and the Stanford-led Energy Modelling Forum study 27 – as well as from specific studies on monetary compensations in climate policy or on the costs of climate policies in a second best world It also participates to the International research network IAMC (Integrated Assessment Modeling Consortium) and to the elaboration of SSP scénarios (Share SocioEconomic Patways).
