As 2025 comes to a close, we reflect on a year of progress, one that has strengthened the Tire Industry Project’s (TIP) collective commitment to advancing credible science, responsible industry practices and meaningful progress on sustainability. As expectations and scientific understanding continue to evolve, TIP’s mission — and the integrity with which we pursue it — has remained constant.
Celebrating our 20th anniversary this year, TIP members once again showed what’s possible when transparency, collaboration and scientific rigor guide our work.
Together, we have advanced scientific understanding in a meaningful way. The publication of the first-of-its-kind State of Knowledge (SOK) papers marked an important milestone for global tire emissions research. Developed by an international group of independent scientists and supported by TIP, the SOK consolidates over 850 research studies, identifies critical evidence gaps, and calls for greater harmonization. It sets a new benchmark for transparency and scientific alignment.
Alongside the SOK, TIP continued to support multiple research projects, guided by an expanded external Assurance Group to maintain objectivity and integrity. Our second Open Call for Projects deepened engagement with researchers, broadening our network and supporting innovative ideas shaping the next chapter of tire emissions research.
This momentum carried into our 2025 Tire Emissions Research Conference, hosted in partnership with MIT, bringing together scientists, engineers, policymakers, and industry leaders across the world to exchange ideas and promote actionable solutions.
In line with our longstanding focus on transparency, we also published our latest KPI Report, tracking members’ collective progress on key sustainability indicators between 2021 and 2024. This annual reporting effort remains a cornerstone of TIP’s approach to accountability and shared improvement.
This year also saw TIP develop and accelerate its End-of-Life Tire (ELT) strategy, advancing circularity and sustainable resource management across the tire industry, publishing action-oriented frameworks and tools such as the Recycling Management Hierarchy.
In addition, the CEOs of the TIP member companies came together in Q4 for their recurring review meeting, to assess the progress and approve upcoming plans, reaffirming their commitment to TIP’s mission.
Looking forward to 2026, TIP’s vision remains clear. We will continue to strengthen scientific understanding of tire emissions, advance best practices across sustainability, and strengthen industry transparency through consistent, credible reporting. And we will do so in partnership with our stakeholders, guided by the values that have defined TIP for the last 20 years.
TIP extends its sincere thanks to its members, affiliates, Assurance Group members and all other partners across the industry who have contributed to its progress this year. Together, we move into the year ahead with optimism and determination, remaining committed to advancing solutions for people, planet and the future of mobility.
