(19/P043) TRENTON – The Department of Environmental Protection reminds individuals that making basic changes in their daily routines can improve air quality across New Jersey while also protecting public health and saving money.

Improve NJ Air Quality“Spring is the perfect time of year to review our daily routines and see what we can do to help improve the quality of the air we breathe,” DEP Commissioner Catherine R. McCabe said. “Everyone can do their part to take simple steps that will help reduce emissions and greenhouse gases and protect public health, like turning our cars off when we’re not driving.”

Some simple changes include combining automobile trips, eliminating car idling, keeping your car’s maintenance current, purchasing an energy-efficient vehicle, and checking the state’s Air Quality Index before heading outside.

New Jersey is a national leader in clean energy and controlling sources of air pollution in the state, resulting in significant progress in improved air quality, including:

  • Electric vehicle registrations have increased from about 500 in 2011 to more than 23,000 today.
  • New Jersey has selected its first round of clean air projects from the federal Volkswagen settlement 533 electric vehicle charging stations throughout the state and eight new electric, zero-emitting, NJ TRANSIT buses that will operate in the City of Camden.
  • New Jersey ranked first in the United States for total installed solar photovoltaic capacity per square-mile basis.

Transportation is the largest source of ozone-forming pollutants in New Jersey and contributes nearly half of the greenhouse gas emissions in the state. Vehicles emit nitrogen oxides that react with other pollutants to create ozone.

Ground level ozone, or smog, is formed through a reaction involving warmer temperatures, sunshine and certain types of pollutants. The young, the elderly and those with respiratory conductions such as asthma are especially vulnerable to the effects of ozone.

Improve NJ Air QualityGreenhouse gases contribute to global warming, which causes more floods, droughts or intense storms, as well as more frequent and severe heat waves. The planet's oceans and glaciers have also experienced big changes oceans are warming and becoming more acidic, ice caps are melting, and sea levels are rising.

As warmer weather approaches the Garden State, residents are encouraged to take steps to reduce air pollutants include:

  • Consider an electric vehicle when it’s time for your next vehicle. Visit to assess affordability, find state and federal incentives, and learn about charging options.
  • Keep vehicle tires properly inflated to increase gas mileage, thereby reducing the amount of pollutants emitted from the engine.
  • Turn the engine off while waiting in line. This will save fuel and money, as well as benefit health. Do not idle your car.
  • Improve NJ Air QualityCombine automobile trips to reduce “cold starts” or choose a cleaner commute by carpooling, using public transportation, bicycling or walking when possible.
  • If your check-engine light is on, get your car emission codes read to determine what type of maintenance your car needs. Ensure your fleet or personal vehicles are properly maintained and inspected at licensed inspection facilities when required. Visit for more assistance.
  • Do not ask a mechanic to remove or change emission control features on your car or truck to improve performance or create “puffs of black smoke.” State and federal laws prohibit tampering with the emissions system of any vehicle.
  • Install solar in your home and offices. Participate in the Community Solar Pilot Program.
  • Use DEP’s mapping application to know the facilities in your neighborhood, their emissions and how DEP controls their emissions.

Everyone, especially those with health problems, is encouraged to check out DEP’s Air Monitoring Alert System, which uses color codes to plan daily activities around current air quality conditions. Conditions are updated daily on the DEP’s Air Monitoring Web site, Overexertion on poorer air quality days can be harmful to your health.

Consider subscribing to EnviroFlash, an online alert system that delivers air quality information to your email inbox or cell phone. You can also see air quality forecasts on Twitter and through RSS feeds through the federal Environmental Protection Agency’s EnviroFlash system. Visit
