Improving Soil Quality & Capturing Atmospheric CO2
Green Golf Carbon transforms golf courses and managed turf into carbon sinks through innovative basalt-enhanced sand technology.

Transforming Golf Courses into Carbon Sinks
Green Sand Advantage
Our enhanced basalt blend delivers multiple benefits over traditional quartz sand, improving turf quality while capturing carbon.
How Our Technology Works
Integrating Basalt Blends into Routine Turf Maintenance for Seamless Carbon Capture

Enhanced Rock Weathering (ERW)
Enhanced Rock Weathering is a natural process that we accelerate to capture CO2 from the atmosphere and lock it away permanently as stable carbonates in the soil.
- ✓Fastest scale, most co-benefits & permanence at half the cost of Direct Air Capture
- ✓1,000+ years of carbon storage durability
- ✓Improves soil fertility, turf productivity & vitality
Basalt Sourcing & Processing
We source high-purity basalt and process it into an optimized blend to maximize its natural reactivity.
Soil Analysis & Deployment
Our basalt blend is applied as part of standard topdressing and aeration routines using existing equipment.
Ongoing Weathering
Once in the soil, the basalt reacts with water and CO2 to form stable carbonates—locking away carbon dioxide for millennia.
Monitoring & Verification
We install monitoring sensors and conduct regular soil tests to verify CO2 uptake and maintain durable carbon credits.
Carbon Credit Generation
Verified carbon removal is monetized via high-quality carbon credits, adding a revenue stream that supports sustainability.
Traditional Sand vs. Green Sand
See how our enhanced basalt blend compares to traditional quartz sand used in golf courses.
