Haque, Fatima; Santos, Rafael M.; Chiang, Yi Wai (2021): Urban Farming with Enhanced Rock Weathering As a Prospective Climate Stabilization Wedge. In Environmental science [&] technology. DOI: 10.1021/acs.est.1c04111.

„With no single carbon capture and sequestration solution able to limit the global temperature rise to 1.5–2.0 °C by 2100, additional climate stabilization measures are needed to complement current mitigation approaches. Urban farming presents an easy-to-adopt pathway toward carbon neutrality, unlocking extensive urban surface areas that can be leveraged to grow food while sequestering CO₂. Urban farming involves extensive surface areas, such as roofs, balconies, and vertical spaces, allowing for soil presence and atmospheric carbon sequestration through air-to-soil contact. In this viewpoint we also advocate the incorporation of enhanced rock weathering (ERW) into urban farming, providing a further opportunity for this recognized negative emissions technology that is gaining momentum worldwide to gain greater utilization.“
