Particle emissions from modern vehicles

Ultra-low sulphur fuels have enabled the introduction of modern engine and after-treatment technologies in order to meet increasingly stringent exhaust emissions limits. Through these improvements, substantial reductions in road vehicle emissions have occurred over the past two decades with corresponding improvements in air quality.

As one example, light-duty diesel vehicles meeting Euro 5 emissions limits will emit less than 5% of the particulate mass (PM) emitted by similar passenger cars just 15 years ago, with comparable improvements in other exhaust emissions.
