Lidl GB has exceeded its sales targets for healthy food in the UK by 80% ahead of schedule, aligning with the Eat-Lancet Planetary Health Diet. The supermarket saw an 82% increase in healthy food sales between 2019 and 2023, surpassing its goal of an 80% hike by 2025. Additionally, sales of plant-based meat, dairy, and other products under its own-label brands skyrocketed by 694% last year, far exceeding the target of 400% growth by 2025.

Lidl's sustainability efforts include plans to increase the proportion of plant-based foods sold by 20% globally by 2030 and make 25% of all protein sales plant-based by the same year. The company is also working to reduce its scope 1 and 2 emissions by 70% by 2030 while focusing on scope 3 emissions, which account for 98% of its climate footprint. Despite challenges, Lidl has made significant progress in sustainability, with initiatives to reduce plastic packaging, donate food surplus, and source materials responsibly.
