The British government has developed contingency plans in response to potential carbon dioxide (CO2) shortages stemming from the ongoing conflict in Iran. In a scenario where the Strait of Hormuz, a critical maritime route for global oil and gas, remains closed beyond June, officials anticipate reduced product variety in supermarkets rather than empty shelves. CO2 is vital for food production, packaging, and healthcare, including the humane slaughter of livestock and the transport of medical supplies. Business Secretary Peter Kyle announced that the Ensus bioethanol plant in northeast England has resumed operations to bolster domestic CO2 supplies. Tesco, the largest supermarket chain in Britain, is collaborating with the government to monitor supply risks, with CEO Ken Murphy stating that current conditions do not indicate immediate food supply issues. However, he acknowledged that the situation could change depending on the conflict's duration and its impact on household costs. The UK government and retailers are focusing on resilience to mitigate any potential shortages.
