NCCR-CLIMATE Phase I (WP4): Integrated Assessment Modelling (IAM)

The overarching questions of WP4.1 (IAM) of NCCR-Climate are as follows:
  1. What is the portfolio of efficient technological and other options to mitigate climate change?
  2. Which policy mix will insure that the most efficient options are selected and promoted?
In the framework of WP4.1 (IAM), the Energy Economics Group (EEG) at PSI concentrated efforts on the development of a global energy-modelling framework for the examination of alternative energy-technology development paths and the associated impact on climate indicators as well as the evaluation of flexible climate policy instruments. These efforts have the general-equilibrium MERGE-ETL model, the energy-system GMM model and the energy-system ERIS model as the core tools and have emphasized the role of technological change in climate-change mitigation strategies. The developments of the ERIS model have been carried out in collaboration with the International Institute for Applied Systems Analysis (IIASA-ECS).
Specifically, significant advances have been made on the endogenization of technology learning, an important driving force in the evolution of global energy systems. The two main technology learning mechanisms, namely Research and Development (R&D) and experience gathered in the marketplace through demonstration and deployment (D&D), have been incorporated in the models in order to capture the early investments required for a technology to progress and achieve long-term competitiveness. Insights from our modelling exercises suggest that models with endogenized technology learning tend to produce lower estimates of the costs of climate-change mitigation policies than models where technological change is exogenous, in particular when higher learning rates are assumed for emerging low-carbon energy technologies. The use of experience curves in this kind of models draws attention to the fact that without accumulation of knowledge through R&D activities and market experience through demonstration and deployment (D&D) programs, cleaner and more efficient low-carbon energy technologies cannot develop and become competitive in the long term.
