Our AQHI light installations will be displayed at various locations. Currently, there's an installation located at City Hall, the CBC downtown studio, the Edmonton Valley Zoo and the Orange Hub.

Resources

Clean air is something we should be working towards every day. Here are some tips on how you can support clean air:

Learn more about air quality in Edmonton, including how to set up your own Air Quality Health Index (AQHI) light bulb and information on AirBeam air monitoring kits. For current data, see the Air Quality Health Index (AQHI).
Be Idle Free: idling your vehicle not only wastes gasoline (and therefore, money), it also causes needless pollution and can be damaging to your vehicle. Protect your wallet and your health - be aware of your idling habits.
Traffic can be a big headache. Lessen the traffic by using alternative modes of transportation. Walk, bike or try taking Edmonton Transit instead of driving. Edmonton Transit is committed to offering environmentally-friendly transportation. Just 1 bus can replace about 50 private cars on the road.
Plant a tree in your community.
Learn about how you can contribute to improving indoor and outdoor air quality at home, school and work.
If you're a grade 5 teacher, check out Inside Education's air quality scavenger hunt and design challenge for your class.
Encourage your organization to become a member of the Alberta Capital Airshed.
