Fuss, Sabine; et al. (2016): Research priorities for negative emissions
Fuss, Sabine; Jones, Chris D.; Kraxner, Florian; Peters, Glen P.; Smith, P.; Tavoni, Massimo et al. (2016): Research priorities for negative emissions. In Environ. Res. Lett. 11 (11), p. 115007. DOI: 10.1088/1748-9326/11/11/115007.
"While there are few pathways to 2 °C that do not rely on negative emissions, 1.5 °C scenarios are barely conceivable without them. Building on previous assessments of NETs, we identify some urgent research needs to provide a more complete picture for reaching ambitious climate targets, and the role that NETs can play in reaching them."
