Our history

Responding to the Dieselgate scandal and its far-reaching implications, the TRUE Initiative was formed as an independent initiative to analyze real-world emissions data. We have since partnered with more than 20 cities in 6 regions around the world, and through our on-the-ground testing campaigns, collected over 4 million measurements.
