Impact of naturally leaking carbon dioxide on soil properties and ecosystems in the Qinghai-Tibet plateau

Abstract One of the major concerns for CO2 capture and storage (CCS) is the potential risk of CO2 leakage from storage reservoirs on the shallow soil property and vegetation. This study utilizes a naturally occurring CO2 leaking site in the Qinghai-Tibet Plateau to analog a “leaking CCS site”. Our o...
