Coronavirus-driven CO2 shortage threatens US food and water supply, officials say

An emerging shortage of carbon dioxide gas (CO2) caused by the coronavirus pandemic may affect food supply chains and drinking water, a Washington state emergency planning document has revealed. The document, a Covid-19 situation report produced by the State Emergency Operations Center (SEOC), contains a warning from the state’s office of drinking water (ODW) about difficulties in obtaining CO2, which is essential for the process of water treatment.

The main reason for national shortages, according to the CEO of the Compressed Gas Association (CGA), Rich Gottwald, is a ramping down of ethanol production. “Back in the summertime, the [Trump] administration exempted some gasoline manufacturers from using ethanol. Then we had Russia and Saudi Arabia flooding the market with cheap gasoline. All of that led to an oversupply of ethanol,” Gottwald said. “As ethanol manufacturers were ramping down because there wasn’t a market for their product, along comes Covid-19, which meant people weren’t driving anywhere”, he added.

Gottwald’s association, along with a number of associations representing food and beverage industries, which together use 77% of food-grade CO2, issued a joint warning to the federal government about the shortage. In an open letter to the vice-president, Mike Pence, the coalition warns: “Preliminary data show that production of CO2 has decreased by approximately 20%, and experts predict that CO2 production may be reduced by 50% by mid-April.” It continues: “A shortage in CO2 would impact the US availability of fresh food, preserved food and beverages, including beer production.”
