Commercial Vehicle SCR Market Size

Commercial Vehicle SCR Market Size

The global commercial vehicle SCR market size was valued at USD 7.9 billion in 2024 and is projected to grow at a CAGR of 5.9% between 2025 and 2034. Stringent emissions regulations are a key growth driver for the market. SCR is used in vehicle emissions control to reduce nitrogen oxide (NOx) emissions from diesel engines.

Governments worldwide are enforcing stricter standards to reduce harmful emissions, such as nitrogen oxides (NOx), from diesel-powered commercial vehicles. Regulations like Euro VI in Europe, Bharat Stage VI in India, and EPA Tier 4 in the U.S. mandate advanced emission control systems, boosting SCR adoption. These regulations aim to improve air quality, reduce carbon footprints, and combat climate change. As technology effectively reduces NOx emissions while maintaining fuel efficiency, it has become essential for compliance. This regulatory push is fostering steady demand for SCR systems in new vehicles and retrofitting older fleets.
 

According to OICA, in 2023, close to 26 million commercial vehicles were produced, rising more than 10% from figures of 23 million in 2022. Thus, coupled with rising regulations and production of demand for commercial vehicles, the market for commercial vehicles SCR is expected to grow parallel. The rising demand for fuel efficiency is another significant driver of the market. These systems not only reduce emissions but also optimize engine performance, enabling better fuel efficiency.
 

With increasing fuel prices and operational costs, fleet operators prioritize technologies that reduce fuel consumption. These systems allow engines to operate at higher combustion temperatures, enhancing efficiency while meeting emission norms. This dual benefit of compliance and cost savings drives the adoption of SCR systems across commercial vehicle fleets globally?.
