The Tire Industry Project (TIP), a voluntary CEO-driven initiative representing ten of the world’s largest tyre manufacturers, including co-chairs Bridgestone, Continental, Goodyear and Michelin, has reported lower carbon emissions intensity, reduced water withdrawals and greater use of renewable electricity among its members between 2021 and 2025.
Its annual report, “Sustainability Driven: Key Performance Indicators for TIP Members 2021-2025”, tracks progress against 16 environmental, social and governance indicators covering seven pathways in TIP’s Sector Sustainable Development Goals (SDGs) Roadmap, which outlines the industry’s contribution to the United Nations’ SDGs.
According to the report, members reduced carbon emissions intensity by 29.2% from 2021 to 2025, including a 4.9% decrease from 2024. Renewable sources accounted for 60.5% of electricity procured by members, up 6.5% from the previous year.
Water withdrawals also fell by 18.4% compared with 2021, including a 5.7% year-on-year reduction in 2025. Withdrawals from water-stressed areas decreased by 35.2% over the same period, with a 10.9% reduction from 2024.
On responsible natural rubber sourcing, all TIP members continued reporting their procurement efforts to the Global Platform for Sustainable Natural Rubber (GPSNR). The report also indicated that 90% of members had independently implemented responsible sourcing policies covering all materials used in tyre production.
The proportion of TIP members with validated science-based targets rose to 90% in 2025, from 80% in 2024.
Dr How Yong Ng, an adjunct professor at the National University of Singapore and a member of TIP’s Assurance Group, said the report showed how members were translating their sustainability commitments into measurable results across the tyre value chain. He also noted that TIP had been monitoring progress against the SDGs for a decade.
TIP has continued funding research into tyre and road wear particles (TRWP) to strengthen scientific understanding of tyre-related pollutants. In 2025, the initiative funded five new research projects and supported the publication of eight scientific papers, twice the number published in 2024.
By the end of 2025, TIP-supported research had produced 36 publications and received 796 citations, a 14% increase from 2024. TIP also committed US$2 million in grants through its first Open Call for Projects, a global initiative aimed at expanding independent research in this field.
Meanwhile, the report also covered progress in tyre circularity, including the publication of the End-of-Life Tyres (ELT) Toolkit 2.0 and the Interactive ELT Data Map, as well as further work on post-consumer recycled (PCR) materials.
TIP said the indicators provide information on the industry’s sustainability progress for policymakers, regulators, industry partners and transport sector stakeholders.
