Summer Months Bring Air Quality Concerns

Automobile use adds to ground level air pollution during the summer months. Exhaust and the simple act of refueling contribute to smog.

The Clean Air Campaign provides education and services to reduce smog and free metro Atlantans from the cycle of traffic gridlock

During smog season, May 1 to September 30, our hot, sunny weather makes it more likely ground-level ozone concentrations will exceed federal limits. In fact, metro Atlanta has recorded exceedences each year since monitoring began in 1980. In 2002, the region experienced 38 days when ozone levels were considered unhealthy for some or all of the population.

In this region, the majority of nitrogen oxides (NOx) emissions – one of two chemical components of ozone - come from cars and trucks. The Clean Air Campaign, a non-profit organization that serves as the clearinghouse for air quality information and traffic mitigation services, works to increase voluntary use of commute alternatives by offering free assistance and financial incentives to employers and commuters. Reducing traffic congestion not only improves air quality, it also improves quality of life, benefiting individuals and employers.

Because ozone is hazardous to human health, one of The Clean Air Campaign’s services is distribution of Smog Alerts on days when ozone levels are expected to exceed federal limits. The Air Quality Index (AQI), used to forecast and report ozone levels, can help determine which days exposure may impact you and your family.

The AQI color codes correspond to increasingly severe conditions and the higher the reading, the more you should consider limiting or postponing outdoor activities. When the AQI rises into “Code Orange” or higher levels The Clean Air Campaign issues a Smog Alert. It is important to note that the highest smog levels usually occur between 3pm and 7pm so that even on Smog Alert Days, you may be okay conducting outdoor activities that occur outside of these hours. Health experts recommend that active people and those with sensitivity to ozone exercise in the mornings rather than evenings on Smog Alert Days.

Because reactions to smog levels can be very different from one person to another, you may need to factor in individual sensitivities or health conditions. Depending on sensitivities, some populations may even need to limit exposure on “Code Yellow” (Moderate) days.

The good news is commute alternatives can help. The best evidence of this comes from the 1996 Olympic experience. During this time, many employers changed their policies, offering teleworking and alternative work schedules, and many residents tried transit. The reduced number of vehicle miles traveled helped reduce ozone concentrations by 28 percent, and emergency room visits by asthma patients decreased by 42 percent, according to a study in the Journal of the American Medical Association.

If you’d like to try a commute alternative, The Clean Air Campaign is offering Cash for Commuters, where you can earn up to $180 over a three-month period by carpooling, teleworking, taking transit, biking or walking. For employers, the organization also offers a vanpool incentive program, where employees can ride for free for three months, and at a reduced rate for an additional period.

10 Solutions to Smog Pollution
  1. Commute by carpool or vanpool, transit, biking or walking
  2. Telework or use an alternative schedule
  3. Combine your trips and errands to reduce driving
  4. Brown bag it – eat lunch in instead of driving
  5. Don’t top off your gas tank – escaping fumes contribute to smog formation
  6. Refuel vehicles after 6 PM or on non-Smog Alert Days
  7. Drive on properly inflated tires and within the speed limit for better gas mileage and reduced emissions
  8. Use electric or natural gas grills instead of charcoal and lighter fluids
  9. Use environmentally-safe paints and cleaning supplies
  10. Be energy efficient by using Energy Star products; turn off lights and office equipment when not in use
