A new Europe-wide benchmark of supermarket sustainability performance suggests that while some retailers are beginning to align with climate and nutrition goals, progress across the sector remains inconsistent. Superlist Europe Environment 2026, led by think tank Questionmark with a coalition of environmental and food system organisations, assesses 27 major supermarket groups across eight European countries.
The benchmark focuses on two areas with significant implications for the food value chain: alignment of climate strategies with the Paris Agreement and efforts to shift protein sales towards more plant-rich diets. Transparency, target-setting and disclosure play a central role in how retailers are assessed.
Retailers in Germany and the Netherlands emerge as the strongest performers overall, with discounter Lidl consistently ranking highly across multiple markets. Several leading chains, including Albert Heijn, REWE, Jumbo and Aldi Süd, have published climate commitments and begun addressing the balance between animal- and plant-based protein sales.
However, the data also indicates that absolute greenhouse gas emissions remain a challenge. Only a small number of supermarkets report sustained emissions reductions since they began disclosures, while emissions across much of the sector have continued to rise. Differences in reporting approaches further limit comparability, reinforcing calls for more standardised, Paris-aligned reporting.
Protein transition is highlighted as a critical lever for reducing Scope 3 emissions. Around two-thirds of supermarkets acknowledge their role in influencing dietary shifts, and some now disclose the proportion of plant-based versus animal-based protein in sales. German and Dutch retailers, along with Lidl in several countries, are among the most advanced in this area. By contrast, a third of retailers in France, Poland, Spain, Sweden and the UK have not yet taken action to shift protein sales towards more plant-based options.
The benchmark also finds that only seven supermarkets have published detailed roadmaps outlining how they plan to lower emissions. For manufacturers and retailers alike, the findings underline the growing importance of credible transition planning, data transparency and collaboration across the value chain as sustainability expectations continue to rise.
