Carbon Footprint — Operations: How does B&Q score?

B&Q reports through parent Kingfisher plc. Kingfisher's 2024/25 Responsible Business Report discloses Scope 1 (83,581 tCO2e) and Scope 2 market-based (11,374 tCO2e) across the group, with GHG Protocol methodology and limited assurance. B&Q does not disaggregate its own Scope 1&2 from Kingfisher's group total. Multi-year tracking shows a 66% reduction in operational emissions since 2016/17. The methodology change in 2024/25 for haulage classification introduces minor comparability issues but the

Carbon Footprint — Supply Chain: How does B&Q score?

Kingfisher quantifies Scope 3 across multiple categories; in 2024/25 total Scope 3 was approximately 19.6 million tCO2e, with product sourcing/manufacturing at 23.8% and customer use/disposal at 61.9% of the total. The group works with Manufacture 2030 to engage suppliers and has set vendor decarbonisation targets requiring top 100 vendors to have SBTi-aligned roadmaps by 2028. However, Scope 3 emissions intensity reduction of 38.7% masks the fact that absolute Scope 3 rose 6% in the most recent

Emissions Trajectory: How does B&Q score?

Scope 1&2 shows strong absolute reduction: 66% since 2016/17, verified through Kingfisher's annual report. However, Scope 3 tells a mixed story. Intensity improved 38.7% per £m turnover since 2017/18, but absolute Scope 3 emissions rose 6% in the most recent year and only fell 30.4% in absolute terms since baseline. Given Scope 3 accounts for 99.5% of total emissions, the overall trajectory is not clearly declining in absolute terms. The switch from intensity-based previous targets to new absolu

Energy Source: How does B&Q score?

B&Q's 2024/25 Build a Life Report states 99% of electricity purchased came from renewable sources. Total energy use has fallen by 34% over the past 10 years. B&Q and Screwfix have purchased 100% renewable electricity since at least 2021 as noted in the Kingfisher SBTi announcement. The logistics fleet has shifted to LNG (105 vehicles, second-largest LNG fleet in UK) and HVO fuel, with emerging EV fleet. This approaches near-complete renewable electricity with active fleet transition underway.

Nature & Biodiversity Impact: How does B&Q score?

B&Q was a founding member of the Forest Stewardship Council in 1993/94. In 2024/25, 99.8% of wood and paper used in B&Q products was responsibly sourced per the Build a Life 2025 report. Kingfisher is a founding member of the Rainforest Alliance's Forest Allies initiative, supporting projects covering 190,000 ha of community-managed forests. B&Q has partnerships with the Woodland Trust for native woodland restoration. The company stopped selling non-native invasive plants, peat-based products, a

Resource Use & Waste: How does B&Q score?

B&Q has launched the 'Refurbed by B&Q' range for secondhand tools, expanded tool hire services, and reports that 64.7% of products sold have more sustainable features. Kingfisher group reports 53% of sales from Sustainable Home Products. The company has removed expanded polystyrene packaging from bedding plants and works with suppliers on packaging redesign. However, no specific waste tonnage data, recycling rates, or circular economy metrics were found in the publicly available information. The

Water Impact: How does B&Q score?

No water consumption data, water footprint assessment, or water management strategy was found for B&Q or Kingfisher. As a home improvement retailer, B&Q is not a water-intensive operation in its direct activities, but its supply chain includes water-intensive products (timber, cement, paint, ceramics). The absence of any water disclosure or water risk assessment, despite the supply chain exposure, limits the score. The company does sell water-efficient products (water butts) to customers but doe

Targets & Commitments: How does B&Q score?

Kingfisher had SBTi-validated 1.5°C-aligned targets approved in 2021. In November 2024, new science-based targets were submitted for SBTi validation: 68% absolute reduction in Scope 1&2 by 2030 (from 2016/17), 46% absolute Scope 3 reduction by 2030 (from 2017/18), net zero operations by 2040, net zero value chain by 2050. The shift from intensity-based Scope 3 targets to absolute targets is a positive step. The 2025/26 targets have been exceeded. No evidence of offset reliance was found; the app

Transparency & Accountability: How does B&Q score?

B&Q publishes an annual Build a Life Project report (second edition in 2025) and benefits from Kingfisher's group-level reporting, which includes a Responsible Business Performance Data Appendix with limited third-party assurance. Kingfisher holds CDP Climate score of A-, uses GHG Protocol methodology, and has dedicated Responsible Business governance at group executive level. B&Q has a Director of Responsible Business. The company reports through Kingfisher's annual report. However, B&Q does no

Controversies & Red Flags: How does B&Q score?

No greenwashing lawsuits, regulatory fines, ASA rulings, or significant environmental controversies were found for B&Q. No InfluenceMap profile exists for B&Q or Kingfisher, and no evidence of anti-climate lobbying was identified. B&Q is not a member of known obstructive trade associations. Kingfisher is a member of EDRA/GHIN which focuses on industry collaboration for Scope 3 reduction. The Scope 3 intensity target framing (per £m turnover) could be flagged as a potential greenwashing risk, but

Making progressPending Review

B&Q reports strong operational emissions cuts (66% since 2016/17) and near-complete renewable electricity (99%), but absolute Scope 3 emissions rose 6% last year despite intensity improvements. Water impact is unreported entirely. Supply chain decarbonisation relies on unvalidated 2024 SBTi targets and vendor compliance mechanisms not yet proven.
