Simple Steps


Metro Denver and the North Front Range’s air quality does not meet current federal standards. Find your “simple step” below to create cleaner air.


Challenge Yourself

You can challenge yourself to improve air quality the entire month of August. Many regional bus and train rides will be free. Hop on to get to the game, a concert, local farmer’s market, or anywhere you and your family go for fun. If this will be your first time on RTD, find your route before you go.

Combine car trips

Combine Trips

Sometimes you just need to drive. It happens. But by adopting a “while I’m out” approach you can have a dramatic impact on our air. Here are a few ideas about how to combine trips:

  • Pick one day each week to run errands. You can even create an “errand bag” (Hello, Pinterest) and fill it with reminders so you won’t forget anything while you’re out.
  • When you order delivery, ask for a bundled shipment to save trips and in summer, have deliveries sent after 5:00 p.m. when possible.

On the Road & At Home

Our air can benefit from small changes to your daily routine.

  • Fill up your car after 5:00 p.m. on hot, sunny summer days and “stop at the click” to prevent gasoline vapors from turning into air pollution.
  • Use low-VOC or water-based cleaners, paints and other products around the house.
  • Switch to electric lawn equipment and mow after 5:00 p.m. when possible.
  • Visit for information on the RAQC’s lawn mower exchange program.

Take public transportation

Take Public Transportation

Metro Denver is fortunate to have multiple public transit choices that are extremely beneficial to overall air quality. RTD will get you around the metro and with CDOT’s Bustang and Snowstang, getting to and from the mountains or along the Front Range has never been more fun. Pack your bags, leave the car in the driveway and say “so long” to sitting behind the wheel in congested I-70 traffic.

Combine passenger trips

Combine Passengers on Trips

Carpooling or vanpooling to skip a car trip has plenty of advantages, including keeping the air clean. In addition to gas savings, carpooling and vanpooling prevents parking woes and allows access to Metro Denver’s HOV lanes. FACT: More time in the passenger seat means more time to catch up on your favorite podcast, show or book.

skip two car trips each week

Skip Two Car Trips Each Week

If you skip two car trips each week and replace them with other ways to get around, you decrease traffic congestion and improve our air quality. Emissions from cars, trucks, vans, and motorcycles are some of the largest contributors to ground-level ozone in Metro Denver.

  • Walk to lunch instead of driving.
  • Walk, jog, or ride a bike if the trip is less than 2 miles.
  • Use e-scooters and bikes or public transit to get to a game, concert, event, or the airport.



Many Colorado employers and employees have realized the benefits of teleworking. We prefer a healthy and prosperous Colorado and understand working from home may not be right for everyone, but for those who can it’s an important solution to air pollution. Even if it’s just one day a week.

Avoid Idling

Did you know that idling uses more fuel than simply restarting your car? When you are stopped for more than 60 seconds, turn your engine off to prevent pollution and save on gas. Each pound of fuel burned produces about 20 lbs of CO2, and a car wastes about .3 gallons of fuel per hour while a big truck wastes 1 gallon/hour.

Energize Your Ride

Driving a low- or zero-emission vehicle, like an electric vehicle (EV), is a common-sense way to create better air in Metro Denver. Colorado has some of the best tax incentives in the nation that make owning an EV easier on the pocketbook. We also have a highly accessible and increasingly growing network of charging stations around the Front Range, and you can charge at home. Visit to see how EVs are better for your wallet and Colorado.

The Regional Air Quality Council (RAQC) is responsible for creating a plan to meet federal air standards. Read about the RAQC’s Ozone State Implementation Plan (SIP), what it aims to achieve in Metro Denver and the North Front Range, and your role in reducing air pollution.
