Virridy Home | Lume — Water Quality Sensing Water for Carbon

Clean Water.
Carbon Credits.
Proven Impact.

Virridy designs and scales drinking water treatment, precision irrigation, and watershed restoration programs—then uses IoT sensors, rigorous science, and digital MRV to verify emissions reductions and generate carbon credits that sustain the service. Our drinking water programs reach communities where most people drink untreated water because they cannot afford fuel to boil it.

Drinking Water Credit Model
Step 1
Clean Water
Deploy water treatment so communities that can't afford to boil—or that burn firewood to do so—get safe drinking water.
Step 3
Fuel Saved
Actual and suppressed fuel demand is eliminated. Avoided emissions from both sources are quantified and verified under Gold Standard and Verra.
Step 2
Monitor & Verify
IoT sensors objectively measure usage. Combined with surveys, audits, and water quality testing for rigorous digital MRV.
CO₂CREDIT
Step 4
Carbon Revenue
Avoided emissions generate certified carbon credits. Revenue sustains and expands the clean water service.
Revenue Reinvested in Water Services

Evidence-Based, Carbon-Financed Clean Water

Hundreds of millions of people lack access to safe drinking water. Most cannot afford the fuel needed to boil it and instead drink untreated, contaminated water—leading to preventable disease and death. Those who do boil consume vast quantities of firewood, driving deforestation and household air pollution. When we provide proven water treatment technologies, we eliminate both the actual and suppressed demand for fuel, and the avoided emissions generate verified carbon credits.

Virridy pioneered this model. Our team developed the first-ever UN Clean Development Mechanism programs earning carbon credits for water treatment, and we've since deployed drinking water treatment programs across five countries in Africa, precision irrigation in Turkey and Mexico, and watershed restoration programs in the US—all financed by carbon credit revenue that sustains the service long-term.

  • 29–49% reduction in childhood diarrhea (peer-reviewed RCTs)
  • IoT sensors objectively verify usage—no reliance on self-reporting
  • 39 publications in The Lancet Planetary Health, Nature, Science of the Total Environment, Communications Earth & Environment, and more
  • 6 drinking water programs across 5 African countries, precision irrigation in Turkey and Mexico, and watershed restoration in the US
  • Gold Standard, Verra VCS, and UN CDM certified
  • Cost-benefit ratio of 5.6x across health, livelihood, and environmental benefits
