Proposed Changes to Metro Vancouver’s Ambient Air Quality Objectives

We want to hear from you

Metro Vancouver is seeking input on the proposed changes to ambient air quality objectives from interested parties representing diverse perspectives, and will consider all feedback in the development of the final ambient air quality objectives.

Metro Vancouver invites you to provide feedback by August 1, 2019, to You can also sign up for a mailing list to receive updates on consultation activities.

Feedback will be considered until the MVRD Board adopts updated ambient air quality objectives. Thank you for taking the time to consider and provide input on the proposed changes to Metro Vancouver’s ambient air quality objectives.

Metro Vancouver is responsible for managing air quality and regulating the discharge of air contaminants in the region to protect human and environmental health. We are seeking input on establishing new air quality objectives, which establish acceptable ambient concentrations of air contaminants. To minimize impacts on public health and the environment, new objectives are proposed for the following contaminants:

  • nitrogen dioxide (NO2)
  • carbon monoxide (CO)
  • ground level-ozone (ozone)

New federal standards are coming into effect for NO2 and ozone, and the provincial government now has a more stringent objective for CO. As a result, following a principle of continuous improvement, Metro Vancouver’s objectives for these air contaminants are being revised to align with other government standards. More detailed information can be found in the Consultation Paper for the proposed changes.

Health Impacts

Nitrogen dioxide, also known as NO2, is produced during high-temperature fuel combustion. On hot and sunny days, NO2 reacts with volatile organic compounds to form ground-level ozone. There is strong evidence that nitrogen dioxide and ground-level ozone have negative heart and lung impacts and can shorten life expectancy. One tool that Metro Vancouver uses to manage these air contaminants is ambient air quality objectives.
