Looking under the hood: A comparison of techno-economic assumptions across national and global integrated assessment models

摘要: Integrated assessment models are extensively used in the analysis of climate change mitigation and informing national decision makers as well contribute to international scientific assessments. This paper conducts a comprehensive review techno-economic assumptions electricity sector among fifteen different global integrated models. Particular focus is given six major economies world: Brazil, China, EU, India, Japan US. The comparison reveals that characteristics quite across models, both for base year future years. It is, however, important recognize assessments from literature exhibit an equally large range parameters reviewed. Beyond numerical differences, representation technologies also differs which needs be taken into account when comparing parameters. While desirable, it seems difficult fully harmonize broader due structural differences technology. Therefore, making available future, together with technology exact definitions should become standard approach allows open discussion appropriate assumptions.
