Sainsbury’s, the UK’s second largest supermarket chain, has announced plans to phase out brown eggs in its own brand ranges as part of its sustainability drive. The move comes after the retailer found that white eggs have a 12.7% lower carbon footprint than their brown counterparts.
Environmental and Welfare Benefits
The supermarket stated that the switch to white eggs will help customers make more sustainable dietary choices without compromising on taste, quality, or nutrition. The lower carbon footprint is largely attributed to better feeding efficiency and the longer productive lifespan of white hens. Additionally, white hens are less prone to feather pecking, leading to improved animal welfare.
A Sainsbury’s spokeswoman explained: “White eggs have the same delicious taste and nutritional benefits as their brown counterparts but result in lower carbon emissions and better welfare outcomes for the hens that lay them. White feathered hens typically live longer, eat less feed, and lay eggs for longer, cutting carbon emissions by over 12% compared with hens that lay brown eggs.”
Collaboration with Suppliers
The initiative is part of Sainsbury’s broader strategy to build a more resilient food system in the UK. The company emphasized its collaborative approach with suppliers to achieve these sustainability goals.
“We know Brits love their eggs, and as we work with suppliers to transition all of our own brand to white shells, they can now enjoy them knowing they are better for the environment and the hens,” the spokeswoman added.
Historical Context and Market Trends
Until recently, almost all eggs sold in British supermarkets were brown. White-shelled eggs, produced by breeds such as the white leghorn (originally from Italy), were predominantly supplied to restaurants rather than retail customers. However, British supermarkets have been testing demand for white eggs in recent years. During the pandemic, Tesco began selling white eggs after lockdown panic buying led to a shortage of brown eggs.
Sainsbury’s decision marks a significant shift in the UK egg market, reflecting growing consumer and corporate focus on sustainability and animal welfare.
