Studies suggest that elevated levels of carbon in plants reduces the rate at which plants lose water through its cells, also known as transpiration. The net result is that various crops may use from 20% to 50% less water when exposed to elevated levels of CO₂.

Because crops require much less water when exposed to CO₂ enrichment, CO₂ gas can be thought of as a “Substitute Good.” This Substitute Good is of particular importance to arid regions like southern California and the Middle East that consume incredible volumes of water for irrigation, yet have skyrocketing metropolitan water demands.

In areas where water supply and consumption is a concern, like the southwestern United States and other arid regions, Carbogation brand systems may have a real economic and agricultural difference by simultaneously conserving irrigation water and increasing crop yields.
