Carbon Footprint — Operations: How does Harvester score?

Harvester is a brand of Mitchells & Butlers (M&B), a UK-listed company with ~1,726 sites and ~£2.6bn revenue (FY2024 Annual Report). M&B discloses Scope 1 and 2 emissions in its Annual Report (most recently FY2024, filed December 2024), with multi-year tracking. However, the publicly accessible extracts of the FY2024 Annual Report do not surface specific Scope 1 and Scope 2 tonne figures in search-accessible form — only targets and progress statements are visible. M&B states it has SBTi-validate

Carbon Footprint — Supply Chain: How does Harvester score?

M&B engaged Bioregional in 2019 to calculate Scope 3 emissions, identifying 15 categories including purchased goods (food) as the dominant source. The company's own sustainability pages state that food sold is its largest GHG contributor. Scope 3 quantification is included in the SBTi-validated net-zero target (2040 for Scope 1, 2 and 3), with a 2030 interim target of -28% Scope 3 against a 2019 baseline. M&B reported an 11% reduction in total footprint (including Scope 3) in FY2023. However, sp

Emissions Trajectory: How does Harvester score?

M&B reported an 11% reduction in total footprint including Scope 1, 2 and 3 in FY2023 (per January 2024 SBTi validation press release). The company's sustainability page states 16% progress towards net-zero by 2040 as of September 2024. M&B has SBTi-validated 2030 interim targets: -70% Scope 1+2 and -28% Scope 3 against 2019 baseline. On-site solar (1,859kWp across 60 sites by end-2024) and 100% renewable electricity tariff indicate genuine Scope 2 reduction trajectory. However, the FY2024 Annua

Energy Source: How does Harvester score?

M&B states it ensures 100% of electricity used is generated from renewable sources, confirmed on its sustainability page and by its Head of Sustainability in a Geo Green Power case study. This is a renewable energy tariff/procurement arrangement, not a wholesale REC-only approach — the company is also actively adding on-site solar PV across its estate, with 60 installations (1,859kWp) completed by end-2024 and targeting over 20% of energy self-generated from solar. M&B is not listed as a RE100 m

Nature & Biodiversity Impact: How does Harvester score?

M&B's sustainability page states it is 'committed to reducing emissions, tackling waste and protecting biodiversity' but provides no quantified nature footprint, no TNFD disclosure, and no deforestation-free commitment with third-party verification. Animal welfare standards for meat and poultry are documented (Red Tractor, Bord Bia, RSPCA-audited), but these relate primarily to welfare, not ecosystem/deforestation impact. A 2021 WWF Palm Oil Scorecard found M&B failed to engage with the scorecar

Resource Use & Waste: How does Harvester score?

M&B reports strong, measurable waste data as of September 2024: 99% of operational waste diverted from landfill (target: 100% by 2030), food waste reduced by 23%, and 60% of overall operational waste recycled. These are specific figures with a disclosed baseline and timeline. The company works with Too Good To Go, saving 500 tonnes CO2e via over 200,000 Magic Bags as of 2024, and with FareShare for food redistribution. A food waste reduction target of 50% by FY2030 is in place. LED lighting and

Water Impact: How does Harvester score?

No water consumption data, discharge data, or water stewardship programme is publicly accessible for M&B or Harvester from searches of their 2022–2024 sustainability disclosures. A 2021 Food Foundation scorecard noted 'review water usage and develop strategy to reduce consumption' as an outstanding action for M&B, with no data found at that time. Restaurant operations involve significant water use (dishwashing, cooking, sanitation across ~1,726 sites) but no water footprint, reduction targets, o

Targets & Commitments: How does Harvester score?

M&B has SBTi-validated net-zero targets (validated January 2024) covering Scope 1, 2 and 3 by 2040. Near-term 2030 interim targets are: -70% Scope 1+2 and -28% Scope 3 against a 2019 baseline. These are SBTi-aligned and represent genuine third-party validated science-based targets with defined baselines and timelines. Additional operational targets include zero waste to landfill by FY2030, 50% food waste reduction by FY2030, and 100% renewable electricity (ongoing). The Scope 3 target of -28% by

Transparency & Accountability: How does Harvester score?

M&B publishes an Annual Report with a sustainability section and has a named Director of Investor Relations and Sustainability (Amy de Marsac). It reports annually against sustainability targets in its statutory Annual Report (FY2024 filed December 2024), covering GHG emissions, waste, food waste, and energy. TCFD-aligned reporting is implied by listing requirements for a UK-listed company. The SBTi validation process itself requires disclosed base-year data and methodology. However, no standalo

Controversies & Red Flags: How does Harvester score?

No upheld greenwashing rulings, regulatory climate fines, or credible NGO reports of systematic environmental harm were found for Mitchells & Butlers or Harvester in recent searches. The company received the Best Sustainable Pub Company award at the Publican Awards 2025. One legacy finding (2021 WWF Palm Oil Scorecard) shows M&B failed to engage with palm oil sustainability reporting — a gap, but not an upheld controversy. No evidence of active lobbying against climate policy or membership of tr
