Working Paper: Monitoring CO2 Concentrations in Soil Gas: A Novel MRV Approach for Cropland-Based ERW?
by Dirk Paessler, Ralf Steffens, Jens Hammes, Ingrid Smet, Carbon Drawdown Initiative, May 17, 2023
This paper discusses the challenges the authors have faced in the past 2.5 years of field-experiments trying to measure the speed of Enhanced Rock Weathering (ERW) in agricultural settings for removing CO2 from the atmosphere. They propose using CO2 sensors placed inside the soil in combination with automated CO2 flux meters on top of the soil as a new method to assess the Carbon Dioxide Removal (CDR) effects resulting from ERW treatments in agricultural settings.
