Why is Drive Clean important?

The Drive Clean program improves air quality and protects people’s health.

Emission technologies in vehicles, even newer ones, can deteriorate over time. Vehicle emissions are responsible for more than 18 per cent of smog-causing pollution created in Ontario, despite today’s cleaner vehicles and fuels.
