Read Aldi Stores Limited (UK subsidiary of ALDI SOUTH Group)'s own report ↗
Aldi UK has validated science-based net-zero targets and reduced operational emissions 4.3% year-on-year, but absolute Scope 3 emissions rose 18% in 2023 due to business expansion. Supply chain emissions remain largely unquantified at entity level. A 2023–2024 greenwashing complaint over the 'carbon neutral' claim—later amended but still present—and NGO criticism of unaddressed meat/dairy sales targets expose a gap between headline commitments and systemic action.
