Toyota vs Volkswagen: Which Car Maker Is More Ethical?

Volkswagen's finance subsidiary settled with the SEC for $48.75 million in March 2024 for defrauding investors by concealing defeat devices in diesel vehicles. Toyota's subsidiaries Daihatsu, Hino Motors, and Toyota Industries were found to have committed systematic certification fraud across 174 test items in 64 vehicle models. Both companies score -70 on data privacy, having each exposed millions of customers' personal information through preventable security failures.

These are the two largest automakers by volume, selling roughly one in every five cars worldwide. Both are also at a crossroads: the transition from internal combustion to electric vehicles is reshaping the industry, and each company's ethical record reflects a different approach to that shift.

Mashinii scored Toyota and Volkswagen across 11 ethical dimensions using court filings, regulatory penalties, and investigative reporting. No self-reported ESG data.

The Scorecard at a Glance

Neither company scores positively across most dimensions. Both carry deep negatives in data privacy, climate, and health. The nature of those failures, however, differs in ways that matter for portfolio alignment.

Dieselgate's Lasting Impact on Volkswagen's Scores

In 2015, Volkswagen admitted to installing software in 11 million diesel vehicles that manipulated emissions test results. The U.S. EPA imposed a $1.45 billion civil penalty for Clean Air Act violations. Research cited in our analysis estimates the excess nitrogen oxide emissions contributed to approximately 1,200 premature deaths in Europe.

The financial consequences continue a decade later. As recently as March 2024, the SEC extracted another $48.75 million from VW's finance subsidiary for concealing the defeat devices from investors. Total Dieselgate costs have exceeded $30 billion when including buybacks, repairs, and settlements globally -- a figure that still appears in the company's risk disclosures.

What changed after Dieselgate matters for scoring. Volkswagen built a Group-wide whistleblower system that received 3,555 reports in 2024, offering anonymous reporting via a 24/7 international hotline and mobile app. The company maintains a zero-tolerance anti-corruption policy with 100% implementation of training for at-risk functions. Five cases of corruption were still ascertained in 2024, resulting in one conviction.

Toyota has no equivalent single scandal. But an Independent Third-Party Committee investigation found systematic certification fraud at Daihatsu, with irregularities across 174 items in 25 test categories covering 64 models. Similar misconduct was identified at Hino Motors and Toyota Industries Corporation. The public announcement of Hino's misconduct came more than a year after discovery. Toyota Industries' misconduct took roughly ten months to disclose.

The pattern is different: one catastrophic, public failure that forced institutional reform vs. a series of quieter failures with delayed disclosure.

Toyota's Emissions Record and Hybrid Strategy

Volkswagen Group's total Scope 1, 2, and 3 greenhouse gas emissions reached 412 million tonnes of CO2 equivalent in 2024. Toyota's global emissions stood at 170 million tonnes in FY2024. The gap partly reflects Volkswagen's larger production volume and its commercial vehicle brands.

On transition pace, the two companies are moving at different speeds. Volkswagen's Scope 1 and 2 reduction targets are validated by the Science Based Targets initiative at the 1.5-degree pathway. By end of 2024, the company achieved a 51% cut -- exceeding its 2030 target ahead of schedule. Two-thirds of Volkswagen's global electricity now comes from renewable sources.

Toyota North America reported Scope 1 and 2 emissions of 823,870 MT CO2e in FY2025, a 32% reduction from FY2019. Renewable electricity accounts for 35% of purchases. The company's carbon neutrality target for North American facilities is 2035, with full vehicle lifecycle neutrality set for 2050. Toyota's climate targets have not received SBTi validation at the 1.5-degree level.

Both companies score negatively on Planet-Friendly Business: Toyota at -50, Volkswagen at -40. Volkswagen's faster transition pace accounts for the 10-point gap.

EV Transition Scorecard

The shift to electric vehicles is not just a business strategy -- it intersects directly with ethical performance. Here is how the two compare.

Toyota's bet on multiple technologies -- hybrids, hydrogen fuel cells, and battery electric vehicles -- reflects a different philosophy. It is a hedged strategy, but one that has drawn criticism for slowing the company's pure EV transition. Volkswagen's more aggressive pivot carries higher execution risk but has produced faster measurable emissions reductions.

For investors, the ethical question is not which strategy is commercially smarter. It is whether the supply chains feeding battery production meet basic human rights and environmental standards -- an area where Volkswagen's contractual mandates score 80 points higher than Toyota's guidelines-based approach.

Factory Workers: Pay, Safety, and Union Rights

Both companies score +10 on Fair Pay & Worker Respect, but the underlying records look different.

Toyota reported a global lost workday case frequency of 0.28 in FY2023. Toyota Kirloskar Motor in India reported a Lost Time Injuries Frequency Rate of 0.25 in FY2023-24. Employee satisfaction at Toyota Boshoku reached 74%.

Volkswagen's Total Recordable Injury Rate was 11.7 in 2024 -- substantially higher. On the other hand, 92% of Volkswagen's European employees are covered by collective bargaining agreements. The company discloses a CEO-to-median pay ratio of approximately 195:1 and a gender pay gap of 13%.

Both companies have recent labour disputes. In 2024, Mexico agreed to ensure Volkswagen provides full backpay and strengthens worker rights protections following a U.S. request. Toyota's subsidiaries faced certification fraud scandals that called subsidiary governance into question.

Supply Chain Ethics: Battery Minerals and Parts Sourcing

The widest divergence between these two companies is in Fair Trade & Ethical Sourcing. Volkswagen scores +30. Toyota scores -50. That 80-point gap is the largest single-dimension difference in this comparison.

Volkswagen mandates its Code of Conduct for Business Partners in all contracts with direct suppliers. Compliance with human rights, environmental, and social requirements is a condition for contract awards. Direct suppliers are contractually required to pass these standards down the supply chain.

Toyota Industries Group surveys 95% of applicable suppliers on conflict minerals and expanded its survey to include cobalt and mica from FY2025. Toyota's Supplier Sustainability Guidelines were revised in 2021. But the framework relies on informing tier 1 suppliers and asking them to implement guidelines -- a fundamentally different enforcement mechanism than contractual mandates.

Neither company's supply chain is clean. In 2024, only 61% of Volkswagen's 3TG suppliers were assessed by the Responsible Minerals Initiative. The company's supply chain in 2023 and 2024 included gold from the Sudan Gold Refinery, which is controlled by a paramilitary group accused of genocide, according to investigative reporting.

Data Privacy: Both Score -70

Both companies score -70 on Safe & Smart Tech. As cars become rolling computers, data security becomes an integrity issue.

Toyota's breach record includes: a 64GB data leak in October 2025; two cloud misconfigurations that exposed car-location data for approximately 2.15 million customers over ten years; an access key left on GitHub for five years exposing roughly 300,000 customer email addresses; a 240GB leak of employee, customer, and financial data in August 2024; and a Medusa ransomware attack on Toyota Financial Services.

Volkswagen's record is comparable. A breach exposed personal data of 3.1 million Americans. A separate incident in late 2024 exposed precise location data for 460,000 electric vehicles and 9.5 terabytes of telemetry data, stored unencrypted on AWS cloud servers. Security researchers described the unencrypted storage as a "fatal mistake."

For context, BMW scores +10 on this dimension, with a public bug bounty program, Privacy by Design principles, and no in-vehicle personal data sales. Its most significant recent breach affected approximately 14,000 customers in Hong Kong -- a fraction of the exposure at Toyota or Volkswagen.

Health Impact: Recalls vs Premature Deaths

Toyota scores -60 on Better Health for All. The company issued recalls in 2025 and early 2026 affecting over 3.3 million vehicles for safety defects including airbag malfunctions, fuel pump failures, and fire risk from engine starter corrosion.

Volkswagen scores -70, largely because of the documented health consequences of Dieselgate. The excess nitrogen oxide emissions contributed to approximately 1,200 premature deaths in Europe. These were not modelled risks -- they were documented regulatory outcomes with a $1.45 billion civil penalty attached.

How Do Other Automakers Compare?

BMW scores +40 on Fair Pay -- the highest among these five. BMW has achieved 100% collective bargaining coverage, near gender pay parity (adjusted gap under 1%), and an accident frequency rate of 2.8 per million hours worked.

Mercedes-Benz matches Volkswagen on ethical sourcing at +30, with 100% of direct suppliers under contractual sustainability requirements and partnerships with NGOs in India and the DRC to prevent child labour in mining regions.

Tesla registers 0 on Planet-Friendly Business -- the best climate score in this group -- but carries the lowest governance score at -60, with $7.4 million in ethics-related fines, removal from the S&P 500 ESG Index, and at least 15 substantiated labour law violations in 2023-2024.

If You Are Buying a Car

For consumers rather than investors, the ethical dimension plays out differently.

If data privacy matters to you: Neither Toyota nor Volkswagen offers a strong record. BMW is the standout in this group at +10. Consider what telemetry your car collects and whether the manufacturer has a history of protecting it.

If supply chain ethics matter: Volkswagen's contractual mandates are meaningfully stronger than Toyota's guidelines. But neither company can guarantee conflict-free battery minerals -- the supply chains are still opaque at tier 2 and below.

If emissions matter: Volkswagen's faster EV transition and SBTi-validated targets suggest a more aggressive decarbonisation path. Toyota's multi-pathway strategy may prove pragmatic but currently produces slower measurable results.

If worker treatment matters: Toyota's safety record is significantly better (0.28 vs 11.7 injury rate). Volkswagen's collective bargaining coverage is significantly broader (92% in Europe).

What the Comparison Reveals

Every automaker in this analysis carries negative scores across multiple dimensions.

Volkswagen has a faster climate transition, stronger supply chain mandates, and a comprehensive whistleblower system built after Dieselgate. It also carries the documented consequences of the largest corporate integrity failure in automotive history and a supply chain that included gold from a genocide-linked refinery as recently as 2024.

Toyota has no single scandal of that magnitude. Its workplace injury rate is substantially lower. But the company shows a pattern of delayed disclosure across three subsidiaries, at least six major data breaches in three years, and a supply chain framework that relies on guidelines rather than contractual mandates.

For investors, the comparison turns on which type of documented failure weighs more: a single catastrophic event that has been penalised and restructured around, or a series of quieter failures that continue.
