Strict emission norms implemented by governments across the globe to curb pollution are expected to drive the diesel exhaust fluid market growth during the forecast period. Many countries in Europe and North America have implemented the Euro 6 and Tier 4 emission standards respectively. These standards promote the usage of selective catalytic reduction (SCR) systems, thereby increasing the consumption of diesel exhaust fluids. The increasing international trade and growing transportation & logistics industries will further drive the demand for commercial vehicles that use diesel exhaust fluids.

Tightening Emission Regulations

The tightening of emission regulations across the globe is a major factor driving the growth of the global Diesel Exhaust Fluid (DEF) market. Governments are focusing on reducing vehicular emissions and improving air quality in their countries. Strict emission norms such as Euro 6 by the European Union and Bharat Stage VI by India that have came into effect recently mandate the use of SCR technology in modern diesel vehicles to cut down nitrogen oxide emissions by over 80%. SCR technology requires diesel vehicles to be fitted with urea-based DEF dosing systems that inject the fluid into the vehicle's exhaust stream to convert nitrogen oxide into harmless nitrogen and water vapor. This has significantly increased the demand for DEF or aqueous urea from the automotive industry. According to the data from the Environmental Protection Agency, the newly introduced emission standards in the United States under their National Program has led to 95% reduction in nitrogen oxide emissions from long haul trucks and buses which has established the country as one of the largest DEF markets currently. Similarly, the statistics from the Department of Environment, Forest and Climate Change of India shows that over 30% of heavy commercial vehicles sold in 2021 were compliant with Bharat Stage VI norms requiring DEF, marking a huge rise over previous years.  Original equipment manufacturers globally have also started proposing SCR systems as standard fittings on their modern diesel models or fleets in order to meet the stringent norms, creating a steady demand stream for DEF. Furthermore, with developing economies pushing for early adoption of advanced emission standards as part of their nationwide pollution control plans, the uptake of DEF is expected to grow multifold in the future. The imminent implementation of next-gen emission regulations such as Euro 7 in Europe from 2025 will further raise the compliance bar and propel higher DEF consumption across major automotive markets.

Stringent emission regulations globally have increased the demand for diesel exhaust fluid. Additionally, , the low consumer awareness about the product and its functioning poses a major challenge. Availability and maintenance of diesel exhaust fluid throughout the vehicle's usage life also remains a concern. High production and transportation costs associated with diesel exhaust fluid make it expensive for consumers. These factors can negatively impact market growth.

Opportunities: Increasing adoption of diesel-powered vehicles and rising pollution levels

The rising levels of vehicle pollution globally pose a major challenge to the environment. Diesel vehicles in particular contribute significantly to toxic emissions like nitrogen oxide. However, this also opens up a big opportunity for the diesel exhaust fluid market. Diesel exhaust fluid, also known as AdBlue, is a liquid reagent that is added to selective catalytic reduction systems in diesel vehicles and machinery to convert nitrogen oxide emissions into harmless nitrogen and water vapor. As more countries implement stringent emission regulations on commercial vehicles and trucks to curb air pollution in urban centers, the demand for AdBlue will see a corresponding rise.  Already, many nations in Europe and regions like California have implemented Euro 6 or equivalent emission standards that make AdBlue mandatory for modern diesel engines to function. With growing evidence that toxic vehicle emissions pose serious health risks, other populous developing countries in Asia and Latin America will also look to tighten their diesel vehicle pollution norms in the coming years. The International Council on Clean Transportation estimates that between 2020-2025, over 80 million heavy and light commercial diesel vehicles will need to upgrade to newer models equipped with AdBlue technology in major global vehicle markets in order to meet increasingly strict emission standards. This translates to a ready customer base and growing need for diesel exhaust fluid to service those newer, cleaner diesel fleets.
