Lifetime Carbon Balance of Enhanced Rock Weathering Explained, Part 2
What the Life-Cycle Assessment (LCA) actually measures and why that matters
Lifetime Carbon Balance of Enhanced Rock Weathering Explained, Part 1
Doesn’t mining and grinding the rock emit more CO₂ than it captures?
New Pre-Print about Enhanced Weathering: It’s Not Just the Rock—It’s the Soil (And it holds on tight)
Based on the large dataset from our greenhouse experiments we have written an extensive paper about alkalinity and cation retention in Enhanced Weathering (EW) projects over recent months.
