Automotive Selective Catalytic Reduction (SCR) Market size was valued at USD 9.88 Billion in 2023 and is expected to reach USD 33.32 Billion by the end of 2036, expanding at around 9.8% CAGR during the forecast period i.e., between 2024-2036. In the year 2024, the industry size of automotive selective catalytic reduction (SCR) is assessed at USD 10.75 Billion. The growth of the market can primarily be attributed to the increasing number of vehicles throughout the world, as well as the worldwide growing emission of nitrogen oxide (NOx) compounds that have generated enormous prospects for market growth. For instance, the emission of nitrogen oxide (NOx) in the United States was found to be about 7.5 million tons in 2021.
In addition to these, factors that are believed to fuel the market growth of the global selective catalytic reduction (SCR) market include the rise in government rules and regulations to control the expanding ratio of emissions. Moreover, there has been a dynamically rising awareness regarding the notable benefits of automotive SCR in decreasing various sort of emissions level, that is estimated to create lucrative opportunities for the expansion of the automotive SCR market in the coming years. For instance, automotive SCR can reduce NOx emissions by up to 91% while also cutting HC and CO emission levels by around 52% to 88% and PM emission levels by 35% to 54%. Additionally, the worldwide expanding advancement in transportation infrastructure is also predicted to present the potential for market expansion over the projected period.
Growth Drivers
Growing Cost of Congestion – The design of SCR technology is such that it allows NOx reduction reactions to take place in an oxidizing atmosphere. As it reduces the levels of NOx using ammonia as a reductant within a catalyst system, it is called selective. It is expected that, to reduce the cost of congestion, the demand for automotive SCR will boost in the forecasted period. It was found that road traffic congestion costs over 1.1 % of the European Union’s GDP.
Growing Concern About Air Pollution –As of the growing count of vehicles and industrialization, the proportion of pollutants in the air has massively increased, which also lowered the air quality. Such air pollution has been damaging the environment. Recent scientific research has revealed that some pollutants can indeed be harmful to public health and welfare even at very low levels. Therefore, the government of nations is now highly concerned regarding air quality and pollution to save the environment, and this factor is anticipated to drive market growth. For instance, it was found that global life expectancy is reduced by an average of 1.8 years per person owing to fossil fuel-induced air pollution.
Rising Penetration of Heavy-Duty Vehicles – It was found that heavy-duty vehicles that run on diesel are responsible for more than 25% of global warming emissions.
Increasing Carbon Dioxide (CO2) Emissions from Passenger Vehicle – As it was found that, an average passenger vehicle emits around 400 grams of Carbon Dioxide (CO2) per mile.
Increasing Urban Traffic – For instance, increased traffic in urban areas was responsible for about 25% of urban ambient air pollution from fine particulate matter (PM2.5) in 2019.
Challenges
High Price of Automotive SCR – The high price of SCR technology, followed by the lack of emission-related regulations in emerging nations, is the major factor that is estimated to push manufacturers to seek alternative emission control techniques for vehicles. Hence, this factor is estimated to hamper the growth of the market during the projected time frame.

Vehicle Type (Light Commercial Vehicle, Heavy Commercial Vehicle, Passenger Car)
The global automotive selective catalytic reduction (SCR) market is segmented and analyzed for demand and supply by vehicle type into light commercial vehicle, heavy commercial vehicle, and passenger car. Out of the three types of vehicle type, the passenger car segment is estimated to gain the largest market share over the projected time frame. The growth of the segment can be attributed to the widespread increasing count of passenger cars throughout the world, coupled with expanding production of these cars. For instance, the worldwide production of passenger cars was expanded from nearly 56 million in 2020 to over 58 million in 2021. Such a booming ratio of passenger cars is estimated to push the market growth further in the coming years, as people are now splurging more on their lifestyle and comfort. Moreover, spiking growth in per capita income along with surge in urbanization are some further factors that are estimated to drive the market growth during the forecast period.
Besides this, the light commercial vehicle segment is also projected to grasp a noticeable market share over the forecast period on the back of the increasing proportion of off-road activities among people, such as trekking, sports, racing, and so on.
Type (Copper Zeolite, Iron Zeolite)
The global automotive selective catalytic reduction market is also segmented and analyzed for demand and supply by type into copper zeolite, iron zeolite, and others. Amongst these three segments, the copper zeolite segment is expected to garner a significant share. The growth of this segment is owing to its outstanding capacity to operate at extreme high temperature ranging from 180 to nearly 600 degrees Celsius, coupled with its high competency as part of an emission monitoring system to convert the nitrogen oxide. On the other hand, the iron zeolite segment is also anticipated to generate good market growth during the projected time frame on the back of its excellent properties, such as extreme thermal constancy. This, as a result, is anticipated to create numerous opportunities for the growth of the segment in the coming years.
