A core element of the TRUE Initiative is the ongoing collection of real-world emissions data from in-use vehicles in cities.

TRUE collaborates with local governments, on-the-ground partners, and research institutions to gather and analyse real-world emissions data that can support low emission transportation policies and actions.

Data comes from two main sources:

  1. Remote Sensing: A non-intrusive technique to capture a short sample of emissions data from vehicles during normal, on-road operation in a city
  2. Database and toolkit analysis: Utilizing existing data sets, new conclusions can be drawn about vehicle fleets and their impact on local environments.

This data can be used to craft new policies and improve existing programs to better address the harmful emissions from motor vehicles and the related health impacts. TRUE’s global reach extends to cities in Europe, North America, Latin America, Asia, and the Middle East.

TRUE analysis can:

  • Demonstrate the extent and negative impact of real-world vehicle emissions in a city
  • Provide evidence and build public support for city-level low-emission transportation policies and actions
  • Accelerate a shift to zero-emission vehicles
  • Encourage an uptake in alternative forms of mobility, such as walking, cycling, and public transport.

The TRUE project has already compiled a large database of real-world emissions data collected by the initiative, third-party institutions, or research consortium (e.g., CONOX and CARES projects, Transport Scotland, etc.).

With ongoing data collection since 2017 in cities around the world, the TRUE Initiative now yields a database of over 70,000,000 vehicle records on 4 continents.
