Brooklyn company Air Co has developed a process for making vodka that converts carbon dioxide into alcohol.
Air Co claims the spirit is "the world's first carbon-negative vodka".
"We invented a way to capture excess carbon from the air and turn it into ultra-refined, covetable products," Air Co said.

The co-founders of Air Co vodka, electrochemists Stafford Sheehan and Greg Constantine, teamed up with a partner to source its carbon dioxide from beverage manufacturing plants and ethanol factories in the northeast of the USA, which produce waste gases and emit CO2.
The collaborator captures the gas, liquefies it at facilities powered by hydroelectric plants and then trucks it to Air Co's facility in Brooklyn's Bushwick neighbourhood. The distilled alcoholic beverage is then made with a process that uses electrical energy to convert carbon dioxide into ethanol, a form of alcohol. Called electrochemical conversion, the process has been around for decades but Air Co claims this is the first time it has been used for large-scale production of vodka.
The brand calculated that the beverage remains carbon negative because the production never makes as much carbon dioxide as the amount originally collected.

To support this, it conducted a life-cycle analysis (LCA) that verifies the amount of carbon dioxide released during the vodka's entire production process. The results are tallied against the amount of carbon dioxide that was collected to first produce the sp...
