Tesla has taken first place in a global ranking of auto supply chain sustainability for the second year in a row. The 2026 Lead the Charge Auto Supply Chain Leaderboard compares 18 major automakers on climate impact, sourcing of raw materials, and human rights performance across their value chains.
Lead the Charge is a campaign run by a coalition of climate, environmental, and human rights groups. It includes organizations such as the Sierra Club, The Sunrise Project, and Public Citizen. The coalition scores automakers on more than 80 indicators that cover issues like deforestation risk, Indigenous rights, and supply chain emissions disclosures.
Tesla pulls further ahead of rivals
In the 2026 edition, Tesla reached an overall score of 49%, which is an increase of six percentage points compared with last year. Ford stayed in second place at 45% after a smaller gain of about two points. So the gap between the two companies has widened to nearly five percentage points, where a year ago it was under one point.
Volvo, Mercedes‑Benz, and Volkswagen complete the top five. Campaigners say these higher-ranked brands have improved at about twice the pace of the remaining 13 automakers since the leaderboard launched in 2023. Yet no company has crossed the 50% mark on the overall score, and that detail has raised concern among advocacy groups about the broader pace of change.
Battery supply chain is Tesla’s strongest area
Tesla’s largest step forward came in the battery category. The company’s score for battery supply chains jumped by about 20 percentage points year‑on‑year, which pushed it past 50% in that section for the first time. For Lead the Charge, that placed Tesla back at the top of the battery ranking.
The report notes that Tesla is the first automaker to fully meet a detailed benchmark for battery emissions disclosure. The company broke out the separate emissions contributions from cell production and from key minerals, including lithium, nickel, cobalt, and graphite. For campaigners and investors, this level of breakdown is important, since it helps them track where supply chain emissions are concentrated and where pressure on suppliers may have the most impact.
Work on aluminum and recycled steel
The report also highlights moves Tesla has made on high‑emission materials beyond batteries. In North America, Tesla has signed an offtake agreement for low‑carbon aluminum with an emission intensity below 2 kilograms of CO₂e per kilogram of aluminum. This lower figure is linked in part to the use of post‑consumer recycled scrap in the material.
The company has pointed to reuse of metals in side projects as well. Its first Tesla Diner in Hollywood was built using recycled stainless steel from Cybertruck production. The diner is a small project in business terms, but it gives a clear example of how Tesla can loop surplus or off‑spec material from vehicle manufacturing back into new uses instead of sending it to waste.
Industry progress is uneven
Lead the Charge says average scores for automakers have nearly doubled since the first leaderboard in 2023. Campaigners link this to more public commitments on responsible sourcing and to growing pressure from regulators, investors, and local communities in mining and industrial regions. Yet the group also points out that even the best‑performing companies on the list still leave a large share of possible actions on the table.
To make that point, the coalition calculated a “theoretical best” score of 86% by combining the strongest category scores already achieved by different automakers. The high figure is meant to show that many of the practices the campaign wants to see are already in place somewhere in the industry. The gap between 49% and 86% is one reason advocates argue there is room for much faster action.
Chinese brands BYD and Geely stand out among the larger movers this year, with gains of about nine percentage points each compared with the previous report. At the same time, Lead the Charge places Toyota, SAIC, and GAC near the bottom of the table. The report criticizes them for limited progress on decarbonizing steel and aluminum and for weak due‑diligence systems on minerals that affect Indigenous land rights and local ecosystems.
For Tesla, the repeat first‑place ranking adds another data point for investors and campaigners who view the company as an early mover on supply chain transparency. The business relies heavily on a vertically integrated model, and that structure gives it direct control over more parts of its supply chain than many legacy automakers have.
For readers who want the full data, the coalition has published the complete 2026 leaderboard and detailed company scorecards on its website.
