Rickels, W.; Merk, C.; Reith, F.; Keller, D.; Oschlies, A. (2019): (Mis)conceptions about modelling of negative emissions technologies. In: Environ. Res. Lett.
"Intentionally removing carbon from the atmosphere with negative emission technologies (NETs) will be important to achieve net-zero emissions by mid-century and to limit global warming to 2°C or even 1.5°C (IPCC, 2018). [...] Here, we show the results from an anonymous expert survey, including 32 Earth-System-Model (ESM) experts and 18 Integrated-Assessment-Model (IAM) experts, about the role of NETs in future climate policies and about how well the various technologies are represented in current models. We find that they strongly support the view that technology portfolios are requires to achieve negative emissions, however, the responses show that the number and range of NETs that can be assessed in IAMs is small and that IAMs and ESMs are rather applied to analyze technologies separately than in combination."
