There's a difference between gas and gas

Our CO2 is exclusively produced from renewable resources within the agricultural industry in the US. This means that the CO2 comes from sources already in the eco-system. We’re not adding any unnecessary CO2 gas to the atmosphere.

This renewable CO2 should not be confused with the CO2 gas extracted from underneath the surface of the Earth, isolated from our atmosphere for millions of years. Instead, our CO2 derives from biomass; corn-based bioethanol production that is continually replenished. It's then purified and certified to become a fresh, food-grade gas for sparkling water makers.
