Outdoor air quality

What you can do to improve outdoor air quality

There are many ways you can reduce outdoor air pollution. Here are some ideas:

Things you can do to reduce air pollution  – on a smog day:
  • Don’t idle your vehicle.
  • Don’t use gas or diesel-powered equipment, including lawnmowers and barbecues.
  • Turn off non-essential lights and electronics.
  • Don’t use pesticides.
  • Don’t paint.

Everyday things you can do to reduce outdoor air pollution – on the road:
  • If you do drive, plan ahead. Make one trip with several stops, instead of separate trips.
  • Don’t idle. If you stop for more than 10 seconds, turn the engine off. Ten seconds of idling uses more fuel than restarting the engine 1.
  • Avoid aggressive driving. Tests show that rapid stops and starts can increase fuel use by about 40 per cent – and only reduce travel time by about 4 per cent 2.
  • Drive more slowly. Reducing your speed from 120 to 90km/hr will decrease fuel consumption by about 20%.3
  • Use overdrive and high gears. Aim for the lowest engine RPM by selecting the highest gear for your speed, whenever possible.
  • Be aerodynamic. Keep your windows rolled up when driving on the highway to cut wind resistance. Less drag means less fuel consumed.
  • Minimize your use of air conditioning. Using your air conditioner in stop-and-go traffic can increase fuel consumption by as much as 20%.4
  • Travel light. The heavier the vehicle, the more fuel it burns. Avoid unnecessary weight.
  • Tune-up regularly. A tune-up can improve the fuel efficiency of your car by 15% and up to 50% if your car has not been regularly maintained 5.
  • Check tire pressure. Properly inflated tires improve fuel efficiency. Driving your vehicle with just one tire under inflated by 6 psi can reduce the life of the tire by 10,000 km and increase fuel consumption by 3%, costing you extra money and releasing more pollution into the air 6.
  • Make sure wheels are aligned and balanced, and ball joints or constant velocity joints are well lubricated.
  • Have your brakes checked. Brakes that drag can decrease fuel efficiency by up to 40 per cent.
  • Clean or replace spark plugs and oil filters; this will help keep fuel consumption and greenhouse gas emissions down.
  • Gas up your vehicle before sunrise or after sundown.
  • Take care not to spill gasoline when filling a tank. Don’t top up- when the gas pump automatically shuts off as you’re filling the tank, don’t add more gas. This could lead to a gas spill.
  • Replace or service the exhaust gas recirculator (EGR) valve. It reduces the emission of a variety of greenhouse gases.
  • Use a timed block heater in cold weather. A block heater warms the oil and engine coolant, making it easier to start your vehicle and improving winter fuel economy by as much as 10%7. Set the timer to turn the block heater on about 2.5 hours before you plan to start your vehicle. Avoid plugging the vehicle in overnight.
  • Have your catalytic converter replaced or serviced regularly.
  • If you’re thinking about buying a new car, pay close attention to fuel efficiency. Chose a car that’s fuel-efficient, buy a hybrid, or find a way of living without a car (car sharing, etc.)
Everyday things you can do to reduce outdoor air pollution – around work:
  • Avoid using a vehicle to get to work. Try car-pooling, take public transit, walk, or ride your bike.
  • Try teleconferencing and telecommuting, to avoid unnecessary travel.
  • Turn off non-essential lights.
Everyday things you can do to reduce smog – in your community:
  • Advocate for cleaner air – tell your elected officials at the national, provincial and local level that you care about clean air, and vote for parties and candidates who support clean air legislation
  • Support and abide by laws intended to clean the air, like pesticide bans and laws against idling your car
  • Lead by example 
  • Interact with like-minded people: GreenNexxus is an online community that allows members to share their environmentally-focused projects and thoughts, belong to groups, invite friends, and attend events.
