Sainsbury’s recently made a significant change in their product offerings, triggering responses from Morrisons and Waitrose. The supermarket giant announced a decision to discontinue the sale of brown eggs and exclusively offer white-shelled eggs under its own brand. This move is in line with Sainsbury’s commitment to sustainability and achieving net-zero targets by 2035, as white eggs have a lower carbon footprint compared to brown eggs.
Despite Sainsbury’s decision, Morrisons and Waitrose have affirmed that they will continue to stock brown eggs, emphasizing the importance of providing customers with choices. Both retailers highlighted their focus on high welfare standards and reducing environmental impact. Morrisons expressed that customers are increasingly seeking sustainable shopping options, hence their decision to maintain brown eggs in their product selection.
The shift towards white eggs by Sainsbury’s is part of their strategy to reach net-zero targets by 2035. White eggs, sourced from white-feathered hens, are known for their longer laying lives and lower feed requirements, resulting in a smaller carbon footprint. Research conducted by SAC Consulting revealed that white eggs have a 12.7% lower carbon footprint compared to brown eggs.
Sainsbury’s aims to achieve net-zero emissions within its operations by 2035 and across its entire supply chain by 2050. A spokesperson for Sainsbury’s highlighted that white eggs offer the same taste and nutritional benefits as brown eggs but contribute to lower carbon emissions and better welfare outcomes for the laying hens.
Similarly, a spokesperson from Waitrose emphasized their commitment to animal welfare and quality, promoting British eggs from reputable, high-welfare farms. Waitrose is on track to achieve net-zero emissions across its UK farms by 2035, showcasing the potential to maintain high welfare standards while reducing environmental impact simultaneously.
