Honda Motor sustainability score: 26/100

Honda reported Scope 1+2 combined at 3.14 Mt CO₂e (FY2024) using GHG Protocol market-based methodology with independent assurance. Corporate activity emissions fell 37.7% versus FY2020 baseline with regional breakdown provided. However, Scope 1 and 2 not separately disclosed at top level.

Honda reports all Scope 3 categories since 2012, totalling 270.53 Mt CO₂e (FY2024), with product use phase representing ~80%. Engaged 500+ North American suppliers on CO₂ reporting (96% procurement spend). Co-developed Automotive Climate Action Questionnaire with Ford and GM. Emissions overwhelmingly driven by combustion vehicles sold.

Total value chain emissions rising: 291.77 Mt (FY2023) to 296.86 Mt (FY2025). Despite 37.7% corporate activity reduction, absolute total emissions trend upward. 2030 EV forecast of 24% falls far below IEA 1.5°C scenario of 66%, making trajectory incompatible with climate goals.

Secured 320MW wind and solar via VPPAs covering 80%+ North American electricity; new 63MW VPPA in Japan. Installed 7.3MW on-site renewable in North America. Committed to 100% renewable by 2050 globally. However, renewable sourcing globally below 90%; Japan and Asia manufacturing still grid-reliant.

Honda identifies biodiversity as material and uses TNFD-recommended methods (IBAT, IUCN Red List, KBAs) for site risk assessment. Joined Japan's 30by30 Alliance; obtained Nature Symbiosis Site certification for 415 hectares at Motegi. No deforestation-free commitment found for supply chain materials (steel, rubber, plastics).

North American plants achieve 98.6%+ zero waste-to-landfill. 2030 target to reduce waste generation 14.5% versus BAU; 2050 target for 100% sustainable materials. European operation reuses 75% wastewater; packaging reuse saved 2,044 tonnes CO₂. Closed-loop systems and supply chain circularity remain underdeveloped.

Zero industrial water intake target by 2050; 2030 target to reduce total intake 14.5% versus BAU. Global sites recycle 3.16 million m³ annually (14% total). Uses WRI AQUEDUCT and WWF Water Risk Filter to assess manufacturing sites. Honda Italia treats and reuses 75% of 4,000 tonnes water annually. Watershed engagement limited.

Honda targets carbon neutrality by 2050 for all products and operations, 30% EV sales by 2030, 100% EV/FCV by 2040, and 46% corporate CO₂ reduction by 2031 versus FY2020. Removed from SBTi for failing to submit within required timeframe. Targets lack independent science validation and rely on intensity-based metrics.

Honda publishes annual ESG Data Books and Reports (2024, 2025) under GRI 2021 with independent assurance. TCFD-aligned climate disclosure and TNFD-aligned biodiversity reporting provided. World Environment and Safety Strategy Committee oversees strategy; CSRD double materiality completed for Europe. Executive compensation linkage to sustainability targets not documented; CDP Climate marked 'Not disclosed'.

InfluenceMap rates Honda D+ for climate advocacy; actively opposes ZEV mandates in US, UK, Japan. JAMA vice chair representing Honda pushed back on stringent G7 regulation. Trade association memberships show mostly negative climate engagement. Removed from SBTi. Historical EPA Clean Air Act settlement ($267M, 1998) and CARB settlement ($1.9M, 2020 small engine violations) noted.
