Sainsbury's, the UK's second largest supermarket, announced it will phase out own-brand brown eggs in favor of white eggs to reduce emissions. The company says white eggs have a 12.7% lower carbon footprint due to better feed efficiency and longer productive lifespans of white hens. The switch also improves animal welfare as white hens are less prone to feather pecking. This move reflects a growing trend in retail to source lower-carbon food options without changing taste or nutrition. White eggs were previously common in restaurants but are now entering mainstream UK supermarkets. The transition supports Sainsbury's goal of building a more resilient food system while helping customers make sustainable choices.
