Summary
Honda achieved marginal improvements in the 2026 edition, improving its overall score by just 2 percentage points this year. As a result, the company remains near the bottom of the Leaderboard rankings.
However, Honda did make notable progress in the two General subsections of the Leaderboard, improving its score by an impressive 17 percentage points in the General climate and environment subsection and by 5 percentage points in the General human rights subsection. This indicates that Honda is beginning to take basic first steps to implement foundational supply chain decarbonization and due diligence processes.
However, these marginal improvements are still not being translated into more targeted action in the remaining issue-specific subsections. In the climate and environment section, Honda continues to score 0%, 1% and 2% on the steel, aluminum and batteries subsections. In the human rights section, Honda’s scores actually decreased in the Responsible Sourcing and Workers’ Rights subsections, by 2 percentage points and 3 percentage points respectively.
This indicates that, rather than building on the limited progress the company has made on overall supply chain sustainability and due diligence, Honda is instead shirking its responsibilities to address adverse human rights and environmental impacts across critical parts of its value chain.
Key Findings
- For the first time, disclosed a full disaggregation of its Scope 3 GHG emissions across all categories, including purchased products and services (Category 1).
- Established a clearer process to monitor supplier CO2 emissions reduction progress, including implementing a PDCA cycle, document request and on-site investigation. Has additionally adopted a visualization system to analyze supplier alignment with Honda’s 2030 and 2050 targets.
- Continues to be the only company to disclose data on water usage by key suppliers (limited to tier 1 suppliers in Japan), through which the company demonstrates progress against targets to reduce water consumption within its supply chain.
- Disclosed minimal details on aluminum recycling processes, though this lacks detail and does not mention post-consumer scrap.
- Launched the ALTNA joint venture with Mitsubishi Corporation, focused on battery health monitoring and repurposing.
- Has yet to take some basic first steps on human rights due diligence, such as requiring suppliers to respect all human rights, disclosing salient supply chain human rights risks, and setting up a supply chain grievance mechanism.
- Strengthened its supply chain risk assessment process, including processes to identify high risk suppliers beyond Tier 1 and monitor supplier compliance.
- Still fares poorly on Responsible Transition Mineral Sourcing, with only limited commitments and supplier requirements in this area. Has disclosed some progress on supply chain mapping, but fails to disclose any information resulting from these efforts.
- Continues to be one of the poorest performing companies on Indigenous Peoples’ Rights and Workers’ Rights in the Supply Chain, having failed to take basic first steps such as committing to respecting FPIC and requiring suppliers to respect the ILO fundamental principles and rights at work.

Honda and Mercedes face allegations of illegal union-busting in the U.S.
Global automakers Honda and Mercedes are facing allegations that they have engaged in illegal union-busting activities in the U.S. Honda has been accused by the National Labor Relations Board of violating the rights of workers at a Greensburg, Indiana, factory by illegally cracking down on union organizing. Mercedes, meanwhile, has been accused by the UAW of engaging “in a relentless anti-union campaign” including the firing of employees who were pro-union and holding frequent captive-audience meetings to spread anti-union views, according to the filing.
