Real-world data for cleaner city air
Every city should have clean transport and healthy air.
The TRUE Initiative supports the development of effective air quality and climate policies using our independent vehicle emissions data, analysis, and expert guidance.
Urban air quality is a global health crisis

Each year, nearly 250,000 deaths are attributed to the pollution caused by dirty transportation. Yet targeting vehicles to improve urban air can often be challenging.
The Dieselgate scandal exposed significant gaps between lab-based testing results and real-world performance, making it difficult for cities to assess vehicles’ impact on air quality and public health.
The TRUE Initiatives provides a new perspective – independent, real-world data collection and analysis that offers a “truer” picture of the sources causing a city’s pollution.
Cities offer a solution
Cities have the ability to address urban air quality at a localized level. As more and more look to develop policies for high-traffic, often under-served areas, the TRUE Initiative’s research can provide the necessary tools to better map their challenges, and the solutions.

TRUE works globally
TRUE works in six regions around the world to support the implementation of solutions such as clean transportation zones, fuel and emission standards, and inspection programs, as well as fleet monitoring and management.
How does your car rate in Europe?
In cities like London, Brussels, and Warsaw, real-world vehicle emissions are often much higher than regulatory standards. The TRUE Rating Tool allows you to explore how your vehicle measures up against European emission standards and offers a closer look at the full magnitude of emissions over its lifetime.
