Urban Air Quality Policies Strengthen Global Catalytic Converter Market Outlook Through 2032

 

The global automotive catalytic converter market continues to gain momentum as rising emission control regulations and accelerating automotive production drive strong demand across regions. According to recent industry estimates, the market is projected to reach US$ 121.74 billion in 2025, supported by stringent environmental compliance requirements and improved adoption of advanced catalytic technologies among OEMs. Over the assessment period from 2025 to 2032, the market is forecast to expand at a compound annual growth rate (CAGR) of 7.2%, ultimately achieving a valuation of US$ 198.06 billion by 2032.

This expansion is fueled by multiple factors, notably the increasing global focus on reducing greenhouse gas emissions, tightening governmental regulations that require vehicles to comply with Euro 6, China 6, and Corporate Average Fuel Economy (CAFE) standards, and rising vehicle production in both emerging and mature markets. Additionally, the growing demand for hybrid and plug-in hybrid vehicles, which still rely on exhaust after-treatment systems, supports steady market growth. Technological enhancements in catalytic coatings, substrate materials, and integrated emission reduction systems are further contributing to the expanding landscape.

Segmentation Analysis

By Type

Automotive catalytic converters are typically segmented into two-way oxidation catalysts, three-way oxidation-reduction catalysts, and diesel oxidation catalysts (DOCs). Among these, the three-way catalytic converter (TWC) remains the dominant segment due to its extensive use in gasoline-powered vehicles and its ability to reduce carbon monoxide, hydrocarbons, and nitrogen oxides simultaneously. The segment continues to benefit from improved coating technologies, precious metal optimization, and advanced substrate structures that enhance overall conversion efficiency.

The diesel oxidation catalyst segment is expected to experience accelerated growth during the forecast period, driven by expanding diesel vehicle usage in commercial and heavy-duty transportation fleets, particularly in Asia Pacific and parts of Europe. Increasing adoption of diesel after-treatment systems, including DOCs combined with diesel particulate filters (DPFs) and selective catalytic reduction (SCR) units, is contributing to higher demand. Meanwhile, two-way catalytic converters, mainly used in older or smaller engine vehicles, continue to show steady but moderate growth due to their limited application range.

By Vehicle Type

The market exhibits strong segmentation across passenger cars, light commercial vehicles (LCVs), heavy commercial vehicles (HCVs), and off-highway vehicles. Passenger vehicles account for the largest share of global demand, owing to their high production volume and broad presence in markets worldwide. As urban populations grow and consumer demand for personal mobility rises, the segment continues to generate substantial requirements for catalytic solutions.

The commercial vehicle segment is anticipated to grow at a faster rate, driven by rising industrial logistics activities, expanding construction and mining operations, and increasing regulatory focus on diesel emission standards. Off-highway vehicles, widely used in agriculture, mining, and infrastructure development, also contribute to rising demand for specialized catalytic solutions due to evolving regulatory frameworks that increasingly target non-road engines.

By Propulsion and Technology

While electric vehicles (EVs) do not require catalytic converters, the global shift toward cleaner mobility has significantly increased adoption of hybrid electric vehicles (HEVs and PHEVs). These vehicles depend on internal combustion engines for part of their operation and thus require modern catalytic converters optimized for varying thermal conditions and intermittent engine activity. This segment is expected to post strong growth over the forecast period.

Advancements in SCR, DPF, and gasoline particulate filter (GPF) technology are also shaping the market. Integration of catalytic converters with particulate filters or NOx reduction modules has emerged as a major trend among OEMs seeking to meet stringent emissions thresholds.
