Sainsbury’s decision to phase out brown eggs from its own-brand range has sparked a wider supermarket response, with rivals Morrisons and Waitrose confirming where they stand on the controversial shift.
The UK’s second-largest supermarket Sainsbury’s recently announced plans to sell only white eggs
The UK’s second-largest supermarket recently announced plans to sell only white eggs across its own-brand lines, citing environmental and animal welfare benefits.
According to Sainsbury’s, white eggs have a 12.7 per cent lower carbon footprint than brown eggs, largely due to the efficiency of the hens that produce them.
The retailer explained that white-feathered hens tend to live longer, consume less feed, and lay eggs for a longer period.
They are also less prone to feather pecking, which can improve overall welfare standards. Despite the change, Sainsbury’s insisted customers would still receive the same “taste, quality and nutrition” they expect.
A spokesperson said the move is part of a broader push to help shoppers make more sustainable dietary choices, adding that the transition will take place as suppliers shift production towards white-shelled eggs.
However, the announcement has not led to an industry-wide shift at least not yet.
Morrisons and Waitrose respond to Sainsbury’s decision to phase out brown eggs
Both Morrisons and Waitrose have confirmed they will continue selling brown eggs, offering customers more choice rather than following Sainsbury’s lead.
Morrisons said it remains committed to stocking brown eggs within its own-brand range, emphasising that shoppers should have the freedom to choose between varieties. The supermarket added that while customers are increasingly looking to shop more sustainably, flexibility remains important.
Waitrose echoed a similar stance but highlighted its ongoing efforts to balance sustainability with high animal welfare standards. A spokesperson said the retailer believes it can “achieve high welfare and reduce environmental impact at the same time,” without removing brown eggs from shelves.
The move marks a notable change in the UK grocery landscape, where brown eggs have long dominated supermarket shelves. Historically, white eggs were more commonly used in the hospitality sector, while British consumers showed a strong preference for brown shells.
That trend has already begun to shift in recent years. During the pandemic, Tesco introduced white eggs to help manage supply shortages caused by panic buying. Since then, supermarkets have been quietly testing consumer demand for the alternative.
Sainsbury’s decision could signal a more significant turning point, particularly as supermarkets face increasing pressure to reduce emissions and improve sustainability credentials.
For now, though, shoppers will still find both options available in most major supermarkets highlighting a growing divide in how retailers approach environmental changes in everyday food staples.
