Research
Building a global database of real-world emissions to improve local air quality and mitigate climate change.
The TRUE Initiative collaborates with local governments, on-the-ground partners, and research institutions to gather and analyze real-world emissions data. These valuable insights help cities around the world as they seek to craft low-emission transportation policies and improve existing programs. These actions will provide effective actions to address the health and climate impacts from on-road vehicles.
Our methods for collecting and analyzing data drives action towards cleaner urban transport.
