This paper aims at providing a consistent framework to appraise alternative modeling choices that have driven the so-called "when flexibility" controversy since the early 1990s dealing with the optimal timing of mitigation efforts and the Social Cost of Carbon (SCC). The literature has...

Modeling of non-carbon dioxide (non-CO2) greenhouse gas (GHG) emissions in integrated assessment models (IAMs) is critical to achieving long-term climate targets. This study selects nine IAMs to reveal the modeling mechanisms and mitigation of non-CO2 GHGs. It further explores the impact of...

Integrated assessment modeling studies the nexus between the systems of climate and economy, both known for their high complexity and vast uncertainty. One key question is how sensitive climate policy inference produced by such models is to the uncertainty in their initial assumptions and the...

This survey examines the history and current practice in integrated assessment models (IAMs) of the economics of climate change. It begins with a review of the emerging problem of climate change. The next section provides a brief sketch of the rise of IAMs in the 1970s and beyond. The subsequent...
