Abstract

âº Urban soils potentially capture 12.5Â kgCO2Â MgâÂ 1Â yrâÂ 1 (value Â£51,843-Â£77,765Â haâÂ 1). âº Formation of carbonate may be significant and exploitable storage route for soil C. âº Urban soil C sequestration can be engineered using Ca/Mg-rich material. âº Soil engineering is a tool in urban ecosystems service provision (carbon capture). âº Conditions for 100% in situ carbonation of Ca/Mg-rich material must be determined.
