Carbon Footprint — Operations: How does Honda Motor score?

Honda reports Scope 1+2 combined at 3.14 million t-CO₂e for FY2024 (ESG Data Book 2024), using GHG Protocol market-based methodology with independent assurance. Multi-year tracking shows a 37.7% reduction vs FY2020 baseline in corporate activity emissions. Granular breakdown by region is provided. Score limited because Scope 1 and Scope 2 are not separately disclosed in the top-level figures found.

Carbon Footprint — Supply Chain: How does Honda Motor score?

Honda reports full Scope 3 across all 15 GHG Protocol categories since 2012, with total value chain emissions of 270.53 million t-CO₂e for FY2024. Category 11 (product use) accounts for ~80% of total. Honda has engaged over 500 suppliers in North America on CO₂ reporting (96% of procurement spend) and co-developed the Automotive Climate Action Questionnaire with Ford and GM. However, emissions are dominated by use-phase of sold products, which are still overwhelmingly ICE vehicles.

Emissions Trajectory: How does Honda Motor score?

While corporate activity emissions (Scope 1+2) fell 37.7% vs FY2020, total value chain emissions are rising: 291.77 Mt (FY2023), 278.59 Mt (FY2024), then 296.86 Mt (FY2025). Total absolute emissions are trending upward. Honda's 2030 EV production forecast of only 24% is far below the IEA's 66% 1.5°C-aligned scenario. The intensity improvement in product use is noted but absolute emissions rising means this cannot score above 4. Scored at 2 due to rising absolute total emissions and slow EV trans

Energy Source: How does Honda Motor score?

Honda has secured significant renewable energy via VPPAs: 320MW of wind and solar covering 80%+ of North American electricity use, plus a new 63MW VPPA in Japan. Honda has installed 7.3MW of on-site renewable generation in North America. The company is committed to 100% renewable energy by 2050 globally. However, renewable sourcing globally is not yet at 90%+ (mainly covers North America), and Japan/Asia manufacturing still relies heavily on grid electricity. VPPAs use RECs which are retired, no

Nature & Biodiversity Impact: How does Honda Motor score?

Honda has identified biodiversity conservation as a materiality and uses TNFD-recommended methods (IBAT, IUCN Red List, KBAs) to assess biodiversity risks at production sites. Honda joined Japan's 30by30 Alliance and obtained Nature Symbiosis Site certification for 415 hectares at Mobility Resort Motegi. BirdLife International supports their assessments. However, quantified nature footprint is limited, and no deforestation-free commitment for supply chain raw materials (steel, rubber, plastics)

Resource Use & Waste: How does Honda Motor score?

Honda's North American plants are virtually zero waste-to-landfill (98.6%+ achieved). The company has a 2030 target to reduce total waste generation by 14.5% vs BAU. Honda aims for 100% sustainable materials by 2050. The European operation developed a wastewater treatment plant reusing 75% of water, and packaging reuse saved 2,044 tonnes CO₂. Honda promotes circular value chain initiatives. However, full closed-loop systems are not yet in place and supply chain circularity is still developing.

Water Impact: How does Honda Motor score?

Honda has set a target of zero industrial water intake by 2050 and a 2030 target to reduce total water intake by 14.5% vs BAU. Global manufacturing sites recycle 3.16 million m³/year (14% of total). Honda uses WRI AQUEDUCT and WWF Water Risk Filter tools to assess water risk at all manufacturing sites. Wastewater is treated and discharged in compliance with local regulations. The Honda Italia plant treats 4,000 tonnes of water per year and reuses 75%. While monitoring and targets exist, verified

Targets & Commitments: How does Honda Motor score?

Honda targets carbon neutrality for all products and corporate activities by 2050, with interim targets of 30% EV sales for automobiles by 2030 and 100% EV/FCV by 2040. It targets 46% reduction in corporate CO₂ by 2031 vs FY2020. However, Honda was removed from SBTi for failing to submit targets within the required timeframe. Without SBTi validation, targets are self-set and intensity-based metrics feature prominently. The carbon neutrality pledge is vague without a science-validated pathway. Re

Transparency & Accountability: How does Honda Motor score?

Honda publishes comprehensive annual ESG Data Books and Reports (2024 and 2025 editions) compiled under GRI 2021 with independent assurance. TCFD-aligned climate disclosure and TNFD-aligned biodiversity disclosure are provided. A World Environment and Safety Strategy Committee oversees environmental strategy. CSRD-aligned double materiality assessment completed for European operations. Annual reporting spans 13+ consecutive years. However, executive compensation linkage to sustainability targets

Controversies & Red Flags: How does Honda Motor score?

Starting at 8: InfluenceMap rates Honda D+ for climate policy engagement, with active opposition to ZEV mandates in US, UK, and Japan, and membership in trade associations (JAMA, Alliance for Automotive Innovation) with mostly negative climate policy engagement (-3). Honda was removed from SBTi for lapsed commitment (-1). Historical EPA Clean Air Act settlement of $267M in 1998 and 2020 CARB settlement of $1.9M for small engine violations are noted but dated (-1). The InfluenceMap finding of a J

Significant gapsPending Review

Honda reports comprehensive Scope 1+2 emissions and full Scope 3 tracking, but absolute value chain emissions are rising despite corporate activity reductions. The company's 24% EV target by 2030 lags climate science requirements. Removal from SBTi, weak climate policy advocacy, and trade association opposition to ZEV mandates expose a fundamental misalignment with decarbonization urgency.
