Coordinated Research Network
The Coordinated Research Network (CRN) will consist of up to 15 standardized experimental field trials across diverse global geographies, beginning with two pilot sites selected in 2026.
By deploying standardized protocols, measurement strategies, and experimental designs on sites over five years, the CRN will achieve what isolated studies cannot: cross-site learning powered by comparable datasets.
The CRN is designed to answer four core scientific questions:
- Across a range of soils and climates, what is the carbon removal potential of ERW and on what timescales?
- How can different CDR quantification strategies be compared and combined to build a more complete picture of ecosystem-level geochemistry — and ultimately, of ERW's carbon removal potential?
- What are the agricultural benefits of ERW, and what factors drive them?
- What happens to weathering products in deeper soils, where reactions may reverse carbon removal but are difficult to observe and are poorly represented in models?
Host sites will receive operational funding, authorship opportunities on site-specific and network-wide publications, and access to a global community of ERW researchers.
