Diesel Exhaust Fluid Market Strengthened by Fleet Expansion
The global diesel exhaust fluid (DEF) market was valued at USD 39,112.7 million in 2024 and is projected to reach USD 61,561.8 million by 2030, expanding at a compound annual growth rate (CAGR) of 7.9% from 2025 to 2030. Market growth is primarily driven by the increasing adoption of DEF in construction and agricultural equipment, where compliance with stringent emission standards is mandatory. Diesel exhaust fluid plays a critical role in modern diesel engines equipped with Selective Catalytic Reduction (SCR) systems. By converting harmful nitrogen oxide (NOx) emissions into harmless nitrogen and water vapor, DEF enables vehicles and off-highway machinery to meet increasingly strict environmental regulations. Growing global emphasis on air quality improvement, sustainability initiatives, and emission reduction continues to accelerate DEF adoption across multiple end-use sectors.
