About the methodologyThis methodology covers durable carbon removal through enhanced rock weathering. This includes crushing and spreading specific types of rocks on soils to increase the rock's surface area exposed to the atmosphere, which speeds up the naturally occurring rock weathering CO2 removal process.Read documentationTechnologyERW projects involve crushing and spreading specific types of rock feedstock within eligible sites, and performing ongoing sampling and monitoring.Carbon removal occurs when atmospheric CO2 dissolved in rainwater reacts with minerals in the rocks, and is converted to stable bicarbonate ions that are transported through the watershed to permanent storage in oceans.The upstream/downstream activities associated with that spreading (e.g. GHG emissions from rock souring, transport...) are also taken into account.Scientific approachThe baseline scenario shall represent the conditions or practices that would occur in the absence of the project.The net CDR from the project scenario is determined by measuring the CDR gains in the Near Field Zone (NFZ), and subtracting the CDR losses in the Far Field Zone (FFZ) and the GHG emissions from upstream and onsite activities.Our calculations compare the quantity of carbon removed from the treatment area where rock is spread (project scenario), to that of the control plots where no eligible feedstock is spread (baseline scenario).Compliance)
