"This special collection encourages submissions to this broad application scheme of EW and welcomes contributions on laboratory experiments, greenhouse experiments as well as field trials. We also encourage submissions on modelling studies, as predictions about the efficiency of CDR, impacts on soil functioning and biological uptake of released elements by EW need improvements, such that in the future EW in combination with other CDR options can be applied in a sustainable way."

Paulo, Carlos; Power, Ian M.; Stubbs, Amanda R.; Wang, Baolin; Zeyen, Nina; Wilson, Siobhan A. (2021): Evaluating feedstocks for carbon dioxide removal by enhanced rock weathering and CO2 mineralization. In Applied Geochemistry, p. 104955. DOI: 10.1016/j.apgeochem.2021.104955.

"We have developed a new method to evaluate the reactivity of mineral feedstocks that consists of a batch leach test using CO₂ coupled with total inorganic carbon (TIC) analysis to quantify easily extractable Mg and Ca from non-carbonate (desirable) cation sources."

"A variety of igneous rocks and minerals are currently under evaluation as potential prospects to facilitate permanent carbon sequestration. Olivine, serpentine, and peridotite are some of the many that bind with carbon dioxide to form carbonates, hence providing a more permanent removal of captured carbon. This post is about a rock that deserves more attention: basalt."

"Project Vesta is excited to announce that Additional Ventures has made a grant of $1.6M in December of 2020, supporting our mission to remove carbon dioxide from the atmosphere. This generous donation will accelerate our progress in advancing the science of coastal enhanced weathering (CEW)."
