Why the NRDE Program Matters

The NRDE Program exists to improve the health of people in Metro Vancouver.

Diesel engines emit a complex mixture of air pollutants. The visible emissions are known as particulate matter (PM) and sometimes called, "diesel soot". Diesel exhaust gases contain particles of carbon coated with other chemicals. These include known, cancer-causing chemicals. When inhaled, the smallest particles can become embedded in the lungs or pass directly into the blood stream.  

Diesel PM is linked to premature death and a number of heart and lung diseases. Diesel PM emissions are responsible for 67% of the lifetime cancer risk from air pollution in Metro Vancouver. Non-road diesel engines are responsible for approximately 41% of diesel PM emissions. Exposure to diesel PM is a health hazard - particularly to children, the elderly, and those working around diesel exhaust. Diesel exhaust is classified as a, "known or probable human carcinogen," by the World Health Organization and US Environmental Protection Agency.

Diesel PM is linked to many other serious heart and lung diseases including:

  • Asthma
  • Chronic obstructive lung disease
  • Chronic bronchitis
  • Pneumonia
  • Cancers
  • Heart attacks
  • Arrhythmia

Operator Guidance


Non-road Diesel Bylaw & Enforcement

Our Officers are responsible for ensuring businesses operate within the terms of the Bylaws and site-specific permits. If a company exceeds these terms, we have several regulatory options available including education, compliance promotion and enforcement measures. Enforcement measures available to us include tickets, notices of bylaw violation and prosecution.

The engine lookup tool can be used to determine if a registered engine is compliant with Bylaw 1161.
