Müller UK & Ireland sustainability score: 28/100

Müller claims 40% Scope 1&2 reduction versus 2015 baseline and 100% renewable grid electricity, but publishes no absolute tonnes CO₂e for any year since 2022. No third-party assurance cited. For a company processing billions of litres of milk across multiple dairies with estimated footprint >100,000 tonnes CO₂e, absence of disclosed absolute data is a material transparency gap.

Müller acknowledges Scope 3 emissions (farm enteric fermentation, soya feed, packaging) and runs Müller Advantage programme for 500+ direct farmers incentivising feed and genetics changes. No total Scope 3 figure published, no methodology disclosed, no third-party verification. Complex global supply chain (South American soya) lacks quantified baseline.

Müller claims 40% Scope 1&2 reduction and early achievement of 2025 target, but zero absolute tonnes disclosed 2022–2025, blocking independent verification. No Scope 3 trajectory published. Company is growing (tripling profits 2024, acquiring Biotiful April 2025, new German facility) raising absolute emissions risk. SBTi commitment pending; no validated targets appear in SBTi dashboard as of research date.

All grid electricity for manufacturing stated as 100% renewable; combined heat and power (CHP) deployed at dairies. No instrument detail (REGO, PPA, on-site solar) disclosed; no third-party verification; not RE100 member. Thermal energy (process heat, gas boilers) dominates dairy processing energy use and is not addressed with renewable claims.

Müller discloses no TNFD alignment, quantified biodiversity footprint, or deforestation-free commitment with third-party verification. Müller Advantage aspirationally reduces soya feed (South American deforestation driver) but progress unverified. Dairy processing carries significant nature dependencies (feed crop land use, nutrient run-off, packaging waste) with no published impact assessment.

Müller discloses concrete packaging moves: clear PET pots (+3,000 tonnes rPET/year), clear caps on milk bottles (1,560 tonnes recyclable plastic), ≥30% recycled content milk bottles, 30% recycled plastic target by 2025. UK Plastic Pact member. Zero-waste-to-business target 2040 and WRAP food waste signatory. Some delivery evidence (clear cap transition 2023); no absolute circularity metrics published.

Müller targets 30% relative water reduction by 2030; states all dairies have energy and carbon systems including water monitoring. No absolute consumption data, no baseline volume disclosed, no third-party verification. For a company processing billions of litres milk annually (typical use 1–5 litres water per litre milk), absence of volumetric reporting is material.

Müller states Scope 1&2 net-zero 2035 and Scope 3 net-zero 2050; claimed SBTi commitment by 2024. No validated SBTi targets appear in SBTi dashboard. Farm 30%-by-2030 target is intensity-based. 40% Scope 1&2 claim unverified. No offset or CDR strategy disclosed. Targets lack SBTi validation and absolute framing.

Müller publishes September 2023 Sustainability Action Plan and website pages but no dedicated ESG report, TCFD, CSRD, TNFD, or CDP disclosure. No third-party assurance statement. No board-level sustainability oversight referenced. Parent company Unternehmensgruppe Theo Müller also lacks quantified data. No executive compensation linkage to sustainability targets disclosed.

No ASA rulings, CMA enforcement, or Environmental Agency notices identified 2022–2025. Not named in InfluenceMap May 2024 EU meat/dairy lobbying report. Member of Dairy UK (mixed climate policy alignment, recorded in EU lobby register). Unverified net-zero claims ('100% renewable', '40% reduction') lack published absolute data or third-party verification, presenting greenwashing risk under CMA rules, though no regulatory action taken.
