Miller & Carter is a UK-based premium steakhouse chain founded in 1976 and operated by Mitchells & Butlers plc. The company operates over 60 restaurants across the UK and Ireland, specializing in high-end beef dining. As a hospitality business within the food service sector, it faces material exposure to agricultural supply-chain emissions and resource impacts.

Miller & Carter operates under SBTi-validated net-zero targets with strong operational emissions reporting and renewable energy deployment. However, beef dominance creates a critical supply-chain blind spot: Scope 3 targets are notably weaker than Scope 1&2, nature and water impacts remain largely unquantified, and biodiversity risk is explicitly deferred to 'future collaboration.' Operational waste performance masks upstream vulnerabilities.
