Diesel Exhaust Fluid (DEF) Market Size & Share, by Component Type (SCR Catalyst, DEF Tank, Injector, Supply Module and Sensor); Vehicle Type (Commercial and Passenger Vehicle) and By Market Type (OEM and Aftermarket) - Global Supply & Demand Analysis, Growth Forecasts, Statistics Report 2025-2037

Growth Drivers

Growing Concern For Vehicular Emissions Amongst Various Nations

According to the World Health Organization (WHO), road transport, mostly diesel traffic, is considered to be a major contributor towards particulate air pollution. Additionally, it also estimated that in the European cities, road transport contributed to around 30% of particulate emissions, followed by 50% in OECD countries.

With the increasing vehicle fleet around the world, the concern for vehicular emissions is also increasing. As such, government of nations around the world are increasingly taking measures to curb the issue of pollution. For instance, in the European Union, stringent norms were introduced gradually to reduce NO_x emissions. The Euro 3 norms which was approved in the year January 2000, had a proposed NOx emission for light commercial diesel vehicle of 0.50 g/km, which further reduced to 0.80 g/km in the proposed Euro 6d norms approve din the year January 2020. Diesel exhaust fluid helps to decrease the emissions of vehicles. Vehicle manufacturers are thereby increasingly deploying the technology to adhere to the stringent emission norms of the governments. Such a factor is anticipated to drive the growth of the global diesel exhaust fluid (DEF) market over the forecast period.

Increasing Deployment of SCR in Vehicles

To meet the emission standards around the world, vehicle manufacturers are increasingly deploying selective catalytic reduction (SCR) technology in diesel vehicles. The technology was first patented in the United States in the year 1957 and was found to be one of the most effective technology to reduce harmful emissions from the exhaust system. The technology involves the conversion of nitrogen oxides with the aid of a catalyst. As deploying the technology allows vehicles to adhere to the requirement of EPA emission regulations, it has been widely accepted amongst vehicle manufacturers till date. Such a factor is thereby anticipated to drive the growth of the global diesel exhaust fluid (DEF) market.

Challenges

Increasing Demand for Electric Vehicles

Rising trend of electric vehicles on the back of increasing awareness for the environment amongst the population, along with the concern for fluctuating oil prices, increasing demand for vehicles that run on alternative sources of energy and difficulties observed in processing urea are some of the factors anticipated to act as a key restraint factor towards the growth of the global market.
