In addition to the general Riverse requirements outlined in the , eligible projects must:
Spread eligible feedstock rocks on eligible sites to generate alkalinity and drive net carbon removals.
Demonstrate capability to perform MRV as agreed upon in the validated project documentation (PDD and Monitoring Plan).
Demonstrate a net-negative project carbon footprint based on initial LCA estimates of induced emissions and initial modeled CDR estimates.
One project shall be defined as any spreading activities within eligible sites within the project lifetime (i.e. the crediting period), and all removal that occurs as a result of that spreading over the project lifetime, plus the upstream/downstream activities associated with that spreading (e.g. GHG emissions from rock souring, transport...).
See the for default crediting period durations, and crediting period renewal.
Rocks must be spread on soils, including but not limited to agricultural fields, forests, prairies, golf courses, and parks. There is no predefined maximum area of a project: spreading sites must be within the same administrative, jurisdictional and geographic area.
See the section for measurement requirements.
Eligible types of feedstock are silicate rocks that also contain alkaline materials. This includes minerals such as olivine, pyroxene, and plagioclase feldspar, and rocks such as basalt, dunite and peridotite. Removals from carbonate feedstocks are currently excluded.
The quantity of feedstock applied must comply with jurisdictional regulations on nutrient and metal additions to soils (e.g., national fertilizer guidelines). The frequency of application is determined by the Project Developer but is restricted to the extent that a robust sampling and MRV plan can effectively distinguish overlapping weathering signals from .
