New Emissions Analytics study suggests pollution from tire wear now 1,850 times worse than exhaust emissions

Green Car Congress

In early 2020, UK-based independent testing firm Emissions Analytics published a study claiming that tire particulate wear emissions were 1,000 times worse than exhaust emissions ( earlier post ). As a result, distance-specific mass and number emissions can be derived, which can then be compared to equivalent tire metrics.

Faurecia acquires Amminex to accelerate efficient NOx reduction for passenger and commercial vehicles

Green Car Congress

ASDS is a system for ammonia storage and delivery that is used to activate the SCR catalysts used on diesel vehicles to remove NOx from the engine exhaust. Conventional dosing technology is based on spraying an aqueous urea solution (diesel exhaust fluid, DEF) into the exhaust stream. At low exhaust temperatures—e.g.
