Carbon Footprint — Operations: How does Miller & Carter score?

Miller & Carter is a brand of Mitchells & Butlers plc (M&B), which reports Scope 1 and 2 emissions in its Annual Report and Accounts 2024 (published December 2024). M&B states that reductions in FY2024 were 'primarily driven by reduced energy consumption, reduced reliance on gas as a fuel.' Specific absolute tonnage figures for Scope 1 and 2 were not extractable from publicly available web search results of the annual report, but the group has a GHG Protocol-aligned methodology and multi-year tr

Carbon Footprint — Supply Chain: How does Miller & Carter score?

M&B engaged Bioregional to map Scope 3 emissions categories (excluding food, which was assessed by the World Resources Institute separately). M&B acknowledges that 'the food we sell is the largest contributor to our greenhouse gas footprint.' Scope 3 targets exist (28% reduction by FY2030 vs 2019 baseline, SBTi-validated). However, Miller & Carter's core business is premium beef steak — one of the highest-emission food products — and no specific supplier-level emissions reductions for beef have

Emissions Trajectory: How does Miller & Carter score?

M&B reported an 11% absolute reduction in total footprint (Scope 1, 2 and 3) in FY2023 versus prior year, confirmed in its January 2024 SBTi announcement. The FY2024 Annual Report notes continued reduction 'primarily driven by reduced energy consumption, reduced reliance on gas.' The sustainability website states 16% cumulative progress toward net-zero target. These are described as absolute reductions, not intensity-only, which is consistent with the SBTi absolute target framing (Scope 1&2: -70

Energy Source: How does Miller & Carter score?

M&B states it 'ensure[s] that all our electricity is generated from renewable sources,' confirmed across multiple sources. A solar PV rollout to 100+ UK venues was completed by end-2024, with a target of 200+ sites, generating an estimated 1,859kWp capacity reducing CO2 by 395 tonnes annually. The company is actively converting kitchens from gas to electric to address remaining fossil fuel Scope 1. The 100% renewable electricity claim is credible but the mechanism (green tariff vs. PPA vs. RECs)

Nature & Biodiversity Impact: How does Miller & Carter score?

Miller & Carter's core product is premium beef steak, a product category with among the highest nature footprints globally — entailing land use, deforestation risk (via feed crops), water consumption, and biodiversity loss from agriculture. M&B acknowledges that the food industry has 'a significant impact on biodiversity' but explicitly describes this as a 'future focus area on which we plan to collaborate with the wide sector' — i.e., no current action is evidenced. No TNFD disclosure was found

Resource Use & Waste: How does Miller & Carter score?

M&B reports strong operational waste performance: as of September 2024, 99% of operational waste is diverted from landfill, food waste has been reduced by 23% (against a target of 50% reduction by FY2030), and 60% of operational waste is recycled against an 80% ambition. 16 tonnes of surplus food was donated via FareShare and 726,000 meals redistributed through Too Good To Go in FY2024 (Annual Report 2024). Zero operational waste to landfill target set for FY2030. These are measurable, publicly

Water Impact: How does Miller & Carter score?

M&B's website acknowledges that the food industry has 'a significant impact on water consumption,' but no specific water usage data, water reduction targets, or water stewardship programmes were identified in publicly available sources. No water bill data, discharge compliance information, or watershed engagement was found. Miller & Carter's beef-heavy menu represents material upstream water impact (beef is among the most water-intensive foods), yet no evidence of water footprint quantification

Targets & Commitments: How does Miller & Carter score?

M&B has SBTi-validated near-term and long-term targets (validated January 2024): Scope 1&2 -70% absolute by FY2030 vs 2019 baseline (well-below 2°C aligned); Scope 3 -28% absolute by FY2030; net-zero across all scopes by FY2040. The long-term target uses SBTi's Corporate Net-Zero Standard and references FLAG (land/agriculture) guidance. Targets are absolute, not intensity-based. Additional operational targets include zero landfill by FY2030 and 50% food waste reduction by FY2030. No evidence of

Transparency & Accountability: How does Miller & Carter score?

M&B publishes sustainability data within its Annual Report and Accounts (TCFD-aligned, confirmed FY2024). A dedicated Director of Investor Relations and Sustainability (Amy de Marsac) is named, with Board-level committee oversight noted ('Board-level committee, steering committee and focused workstreams'). The company won the 'Best Sustainable Pub Company' at the Publican Awards 2025. TCFD disclosure is included in the annual report. However, no evidence of executive compensation linked to susta

Controversies & Red Flags: How does Miller & Carter score?

No regulatory actions, ASA/FTC rulings, credible greenwashing complaints, environmental fines, or significant controversies were found for Miller & Carter or Mitchells & Butlers in relation to environmental matters. No evidence of climate lobbying or membership of trade associations actively opposing climate policy was found; M&B is a hospitality company not typically engaged in fossil fuel or industrial lobbying. The company received a sustainability award (Publican Awards 2025 Best Sustainable
