There's a CO2 shortage across Europe right now - and there are fears it could lead to a beer and fizzy drink shortage during the World Cup.

A number of producers are closed for maintenance during the summer months meaning production is halted - while the British Beer and Pub Association predicted last week England fans would buy 14million extra pints during the World Cup group stages.

In the worst case scenario, pubs could be hit by beer shortages during key England matches, the Mirror reports.

Brigid Simmonds, chief executive of the British Beer and Pub Association, said: "We are aware of a situation affecting the availability of CO2 across Europe, which has now started to impact beer producers in the UK.

There could be a shortage of beer during the World Cup

"We have recommended our members to continue to liaise with their providers directly where they have concerns over supply.

"We will continue to monitor the situation carefully. However, given the time of year and the World Cup, this situation has arisen at an unfortunate time for the brewing industry.”

It is unclear which specific companies have been hit by the shortfall.

Gavin Partington, director general of the British Soft Drinks Association, told Sky News : "The shortage of CO2 across northern Europe is impacting a wide range of businesses across the food and drink sector.

"Soft drinks producers in the UK are taking active steps to maintain their service to customers including working with their suppliers to mitigate the impact as well as looking at alternative sources."

GasWorld reported ammonia plants, which produce one of the key sources of food-grade CO2, generally shut down for maintenance during the summer months, with their peak production running from August to March.

High natural gas prices mean there is little incentive to produce lots of ammonia, one of the key ingredients of food-grade CO2

And high natural gas prices have dented the amount of money ammonia producers can make at an already quiet time of year.

With many big plants offline and little financial incentive for ammonia producers to get them up and running again at speed, supplies face the risk of running dry.
