"Carbon dioxide adsorbents based on the reaction of pentaethylenehaxamine (PEHA) or tetraethylenepentamine (TEPA) with propylene oxide (PO) were easily prepared in “one pot” by impregnation on a silica support in water. The starting materials are readily available and have a low cost facilitating the production of the adsorbents on a large scale. The prepared polyamine/epoxide adsorbents were efficient in capturing CO2 and regenerable under mild conditions (50‐85 °C)."

Brown, C.; Alexander, P.; Arneth, A.; Holman, I.; Rounsevell, M. (2019): Achievement of Paris climate goals unlikely due to time lags in the land system. In: Nat. Clim. Chang. 9 (3), S. 203–208. DOI: 10.1038/s41558-019-0400-5.

"These shortcomings are partially the result of avoidable ‘blind spots’ relating to time lags inherent in the implementation of land-based mitigation strategies. Key blind spots include inconsistencies between different land-system policies, spatial and temporal lags in land-system change, and detrimental consequences of some mitigation options. We suggest that improved recognition of these processes is necessary to identify achievable mitigation actions, avoiding excessively optimistic assumptions and consequent policy failures."

"As global emissions of carbon dioxide (CO2) continue to exceed levels compatible with achieving Paris Agreement targets, attention has been focusing on the role of bioenergy as a ‘renewable’ energy source and its potential for removing CO2 from the atmosphere when associated with carbon capture and storage (CCS). The European Academies’ Science Advisory Council (EASAC) examined these issues in 2017/18, but since then many peer-reviewed papers and international reviews have been published. EASAC has thus revisited these important issues and updates its earlier findings in this commentary."
