Central Oklahoma Air Quality

A Guide to Safeguarding Health, Advancing Equity and Driving Economic Growth

Imagine an Oklahoma where every community breathes clean air, businesses thrive through sustainable practices and future generations inherit a healthier, more resilient environment and economy.

The Oklahoma Regional Air Quality Plan, led by ACOG, is more than a policy — it's a vision for change.

 By working together to tackle emissions and drive sustainable economic growth, we can protect our communities, spark innovation and build a future we can all be proud of.

Together, we’re shaping a healthier, more vibrant Oklahoma.

  • Take Mass Transit

    The average driver spends about 64 cents per mile to drive their personal vehicle, including ownership and maintenance. By opting to take public transit or carpooling just once a week, you’ll save money and reduce traffic congestion and air pollution. Fewer vehicles on the road mean fewer sources of Volatile Organic Compounds (VOCs) and Nitrogen Oxides (NOX). A reduction in these ozone-forming components may result in an overall improvement of the local air quality

  • Combine Errands - Trip Chain

    Chances are, you’re already trip-chaining by combining your errands into one trip. It helps you get things done and reduce traffic congestion and air pollution.

  • Ride Your Bike

    Transportation accounts for 29 percent of all air pollution nationwide; ride a bike or walk for short trips during morning hours when ozone levels are lower.

  • Walk Instead of Ride

    Walk or skate instead of driving! These modes of transportation are easy ways to get exercise and they’re easy on the air.

  • Care for your Car

    Regular maintenance, tune-ups, oil changes, and checking tire pressure can improve gas mileage, extend your car’s life, and increase its resale value. It can also reduce traffic congestion by preventing breakdowns and lead to reduced emissions.

  • Fuel When It's Cool

    SKIP FUELING ON OZONE ALERT DAYS! Refueling during cooler periods of the day (morning/evening) can prevent gas fumes from heating up and creating ozone. This is essential to practice on air alert days when high ozone levels may be present.

  • Don't Top Off The Tank

    Topping off your tank releases gas fumes into the air and cancels the benefits of the car’s antipollution equipment. This practice is also dangerous because it can lead to spills, with gasoline either getting on your body, clothes, or on the ground. Stopping short of a full tank is safer and it reduces pollution.

  • Telecommute - Work from Home

    Work from home if possible. You’ll save time and money while reducing emissions and traffic congestion.

  • Know Before You Go

    Be in the know about traffic in your area: tune into your local radio for traffic reports, watch local news, or map your route via smartphone application. Get traffic updates before you leave home and you won’t get stuck in a traffic jam, preventing your car from running/idling longer than necessary.

  • Avoid Drive Thru - Go Inside

    Idling your vehicle for more than 10 seconds uses more fuel and emits more CO2 than turning off and restarting your engine. Every time you use a drive-thru window you waste gas, money, and emit air pollution by idling. Do your part! Next time you are at a fastfood restaurant, ATM, bank, or other location with a drive-thru, go inside instead.
