Integrated Assessment Models: what are they and how do they arrive at their conclusions?

Bioenergy, like that produced from rapeseed, represents a	key area of uncertainty in IAMs.

Integrated Assessment Models (IAMs) models are used to evaluate the technological and economic feasibility of climate goals such as the Paris Agreement’s long-term temperature goal to hold global warming well below 2˚C and pursue efforts to limit this warming to 1.5˚C above pre-industrial.

The results of these models are assessed in Intergovernmental Panel on Climate Change (IPCC) reports, and play a central role in the IPCC Special Report “Global Warming of 1.5°C” (SR1.5).

This briefing sets out some of the important context and caveats in relation to understanding IAMs and their results, particularly in relation to the Paris Agreement’s 1.5°C limit.
