Many Options Available to Help Reduce Auto Emissions

Now that the prime of summer has reached us, the importance of keeping the region’s air clean is at an all-time high. The Clean Air Partnership, along with several other organizations, helps play a significant role in raising awareness about all the ways people in the St. Louis region can reduce emissions to help keep the air quality in healthy ranges. With transportation being one of the biggest contributors to air pollution, much of the focus is on communicating the many benefits of alternative transportation options, such as transit use or carpooling, or walking or riding a bike when air quality conditions are good.

Thankfully there are plenty of resources available to help members of the St. Louis community take voluntary steps that can improve the quality of the air we breathe and improve our health overall. Area residents are encouraged to check out the following:

    • The region’s public transit system is designed so riders can walk to a nearby stop, or park and take a train or bus, or a combination of the two, to get where they’re going – safely, comfortably and conveniently.  ( or
    • Citizens for Modern Transit offers a Guaranteed Ride Home program as an incentive for commuters that allows employees to take transit/bicycle while providing them a “safety net” – an assurance they can get home and not be left at work if a situation arises. (
    • RideFinders provides free carpool and vanpool ride-matching services for commuters in the St. Louis region to save money, reduce traffic congestion and improve air quality. They also offer a version of the Guaranteed Ride Home program! (
    • Don’t let worry about potentially needing a car during the day derail plans to share the ride. Consider carsharing opportunities to get to and from midday errands and meetings when needed. Visit for more information.
    • Visit or use MoDOT’s 511 travel information number to get real-time traffic information and use it to better plan your route to avoid traffic tie-ups and construction zones.
    • LimeBike and Ofo are bike-sharing companies that offer a great alternative to hopping in your car for short trips. Users download one of the smartphone apps to find a bike nearby. When they get to the bike, they can enter a code to unlock it via their phone, pedal where they need to go, lock it up and leave it for the next user. (
    • Ridesharing services such as Uber and Lyft match drivers of private vehicles to those seeking transportation and are a great option for group outings to eliminate the use of multiple vehicles.

MoDOT – Guiding the Region to Cleaner Air

As the Clean Air Partnership works to encourage activities that reduce emissions, we continue to spotlight organizations in the St. Louis region that share our passion. With transportation being one of the largest contributors to air pollution, the efforts carried out by the Missouri Department of Transportation (MoDOT) are crucial in championing clean air.

MoDOT oversees a total of 33,856 miles of roadway throughout the state and, while commuting by automobile is necessary for many, MoDOT recognizes the importance of keeping congestion-related emissions at a minimum.  Considering idling vehicles emit 20 times more pollution than a car traveling 30 miles per hour, alleviating congestion that causes stop-and-go traffic is key in promoting cleaner air.

Here is a look at several of the initiatives MoDOT has implemented to help keep traffic flowing, decrease emissions and clear the region’s air:


  • Gateway Guide – This initiative combines several tools to provide motorists with real-time traffic updates. Traffic sensors alongside the road provide information on upcoming traffic speeds and volumes. MoDOT utilizes over 100 Dynamic Message Signs across the state which are permanent message boards located along state highways used to broadcast information regarding travel times, interstate closures, vehicle crashes and congestion. The @StLouisTraffic Twitter feed shares real-time information on closed lanes and roads. Closed-circuit cameras positioned throughout the region also provide real-time footage of area highways. These cameras provide video to help direct emergency response forces to quickly and safely address incidents. More importantly, the camera footage is streamed on Gateway Guide. MoDOT’s intent is that motorists will use this information to take alternate routes when traffic is heavy. By shifting traffic flow in various directions, congestion can be alleviated or avoided, ultimately reducing vehicle emissions.

  • Ozone Information – During the ozone forecasting season, MoDOT operates eight portable message boards alongside roadways in the St. Louis region. These, along with the Dynamic Message Signs, present the daily ozone forecast and often provide motorists with air-friendly tips. For example, when the air quality is poor, the message board not only notifies motorists of the red state of the air, but it might also encourage motorists to avoid filling up with gasoline until after 7 p.m., to help prevent the development of ground-level ozone. These boards have the potential to reach more than half a million travelers in just one day and encourage the community to take part in activities that keep the air cleaner.


  • Modification of Daily and Internal Operations – When the air quality is predicted to be poor, MoDOT works especially hard to alleviate congestion. This means halting routine maintenance operations on state highways that might create congestion and vehicle idling when the air quality is red.  MoDOT also encourages their staff to use alternative forms of transportation and has a carpooling program in place for employees to team up to share the ride. These modifications further help to reduce pollution and improve the quality of the air we breathe.
