Exhaust Aftertreatment System Market

The exhaust aftertreatment system market is expected to grow from USD 32.77 billion in 2025 to USD 40.93 billion by 2032 at a CAGR of 3.2%. This market is driven by a rise in stringent emission regulations, increased penetration of advanced gasoline and diesel powertrains, and the need for OEMs to comply with real-driving emission (RDE) and particle number (PN) limits across the majority of the automotive markets, such as China, India, and others. Regulations such as China 6, Euro VI/VI-d, BS VI, and EPA 2010 have mandated the adoption of multi-component aftertreatment architectures, including DOC, DPF, SCR, GPF, LNT, and auxiliary catalysts, which in turn are increasing the requirements for per-vehicle aftertreatment systems. Moreover, the shift toward gasoline direct injection (GDI) engines and high-efficiency diesel platforms has accelerated demand for GPF and SCR systems, reinforcing OEM dependency on advanced emission control technologies.

The exhaust aftertreatment system market is led by prominent companies such as Tenneco, Faurecia (now part of FORVIA), Continental AG, Eberspächer, Futaba Industrial, Sango, and Friedrich Boysen, which together account for a substantial share of OEM installations. To sustain competitiveness, leading players are focusing on technology upgrades aligned with future emission norms, platform-level collaborations with OEMs, localization of manufacturing, and integration of advanced catalyst formulations and dosing technologies. Strategic investments in cost optimization, regulatory readiness, and global platform standardization remain central to expanding the OEM customer base and maintaining leadership across regions.
