Müller UK & Ireland publishes sustainability targets but provides no verified absolute emissions data, no third-party assurance, and no SBTi validation despite claiming 2024 commitment. Core weaknesses: unsubstantiated carbon claims, missing Scope 3 quantification, and no nature risk disclosure across a supply chain dependent on deforestation-risk soya.
