Methodologies under the BioCarbon Water Standard establish science-based requirements for quantifying measurable water benefits from projects that improve water security, protect watersheds, restore ecosystems, enhance water availability, and reduce pollution.
They apply to eligible water projects and nature-based solutions focused on sustainable water management, aquifer recharge, water source protection, efficient water use, soil and landscape management for water retention, and water quality improvement.
Each methodology defines the technical requirements, indicators, baseline conditions, monitoring procedures, and assessment criteria used to determine eligible water outcomes under the BioCarbon Water Standard.
By providing clear and traceable quantification rules, these methodologies contribute to credible water crediting, transparent environmental claims, and finance for projects that protect critical water resources.
