The UK could face some gaps on supermarket shelves this summer if disruption caused by the Iran war continues, with shortages of carbon dioxide potentially hitting supplies of chicken, pork and fizzy drinks.
Government ministers are reportedly drawing up contingency plans for a “reasonable worst-case scenario” if the key shipping lane of the strait of Hormuz does not reopen, disrupting supplies of the CO2 required by the food industry.
Officials from government departments including No 10, the Treasury and the Ministry of Defence have run a planning operation named Exercise Turnstone to rehearse various scenarios of how British industry could be affected by a long closure of the strait, the Times reported.
The planning exercise, run by the government’s Cobra emergency committee, was said to be based on the assumption that the maritime channel remained closed in June and that a permanent peace deal between the US and Iran had not been reached.
The business secretary said on Thursday that the public should be “reassured” by the fact that ministers were making contingency plans to deal with possible consequences of the Iran war, adding that supplies of CO2 were “not a concern” for the UK economy.
Peter Kyle called the leak “unhelpful”, telling Times Radio: “The public need to be reassured that we are doing this kind of planning and we are doing this kind of scenario planning.”
His comments came as the boss of Tesco, Britain’s biggest retailer, said it was not aware of any problems with carbon dioxide availability across its supply chain.
CO2 is a byproduct of industrial production, but is widely used across numerous industries, particularly farming, food production and hospitality.
The gas is essential for the humane slaughter of livestock as it is used to stun pigs and chickens, while it is also widely used in the packaging of fresh meats and fresh produce such as salad and baked goods, where it halts bacteria growth and extends shelf life.
CO2 is necessary for fizzy drinks and beer, as well as being vital for cooling systems used to refrigerate products.
Beyond food and hospitality, it is also needed for surgical procedures, MRI scans and cooling nuclear power plants.
The UK is one of Europe’s largest users of CO2. In March, Kyle said the government would invest £100m to reopen the mothballed Ensus bioethanol plant on Teesside over fears that the war in Iran could trigger shortages of the gas.
On Thursday he said the decision to restart the Ensus plant for three months meant “people should be reassured that we are doing this kind of action behind the scenes to keep resilience in our economy” at a time when the situation was still unfolding in the Middle East.
He told Sky News: “If any of these things change, I will be upfront with the public about it in advance so that we can prepare. But right now, people should go on as they are, enjoying beer, enjoying their meats, enjoying all the salads.”
Ken Murphy, the chief executive of Tesco, said the government was “doing the right thing in planning for a worst case scenario” on potential interruptions to CO2 supply, it had made a “reasonable analysis” and welcomed the reopening of the Teesside plant.
But he said Tesco had “seen nothing at this point” in terms of problems within its supply chain caused by issues with CO2 availability and that “at this point none of our suppliers have flagged any issues to us”.
Murphy said that after six years of various crises – from Covid to Brexit – Tesco was confident it could head off problems with supply and was “constantly working on various scenarios internally”.
He added that the biggest impact on supply chains in recent months had come from terrible weather in the south of Spain and north Africa and shoppers would not have noticed gaps on shelves because Tesco was able to flex its supply chain to keep goods flowing. “We are making sure we head off any issues at the pass well ahead of time,” he said.
