What Needs to Be Done

Many major challenges require the Administration, working through the EPA, and Congress to take steps to protect the health of the public. Here are a few that the American Lung Association calls for to improve the air we all breathe, starting with cleaning up smokestacks and tailpipes.

Clean up harmful emissions from smokestacks.

Clean up harmful emissions from tailpipes.

Reduce emissions of wood smoke.

Improve the air pollution monitoring network.

Adopt an ozone standard that follows the law and protects health.

Protect the Clean Air Act.

What you can do.

Clean up harmful emissions from smokestacks. 

  • Carbon pollution. Power plants are the largest stationary source of greenhouse gases in the United States. Energy production accounts for 86 percent of total 2009 greenhouse gas emissions, and the electric sector represents 39 percent of all energy-related carbon dioxide (CO2) emissions.1 In 2013, President Obama pledged to reduce carbon pollution from power plants. Now the EPA needs to finish the job and issue strong final standards for carbon pollution from new and existing plants.
  • Transported ozone and particle pollution. In 2011, the EPA set tough new limits on ozone and particle pollution that could blow across state lines and add unhealthy air downwind. That same year the EPA also, for the first time, set national limits on the toxic pollutants these power plants can emit. However, these standards have been blocked in the courts. The Lung Association has taken legal steps to defend the EPA's efforts. The EPA and the states must move forward with actions to clean these plants up. 

Clean up harmful emissions from tailpipes.

  • Dirty diesel vehicles and heavy equipment. Rules the EPA put in effect over the past several years mean that new diesel vehicles and equipment must be much cleaner. Still, the vast majority of diesel trucks, buses and heavy equipment (such as bulldozers) will likely be in use for thousands more miles, spewing dangerous diesel exhaust into communities and neighborhoods. The good news is that affordable technology exists to cut emissions by 90 percent. Congress needs to fund the EPA's diesel cleanup ("retrofit") program. Congress should also require that clean diesel equipment be used in federally-funded construction programs.

Reduce emissions of wood smoke.

  • Residential wood burning devices, including as outdoor wood boilers and stoves, are the largest residential source of particle pollution. Emissions harmful air pollutants from wood burning devices have worsened air quality and public health in many cities, such as Fairbanks and Salt Lake City. These devices could have significant impacts on their owners and immediate neighbors. The U.S. Census reports that nearly two percent of all U.S. households use wood as a primary heat source.2 In 2006, one study estimated that approximately 14 to 17 million such devices were then in use in the United States.3
  • Besides particle pollution, wood burning also produces carbon monoxide, nitrogen oxides, sulfur dioxide, and even toxic air pollution. Studies have found that wood smoke leads to coughing and shortness of breath, decreases in lung function, and aggravated asthma and may even cause cancer.4
  • The EPA has not updated national standards for these devices since 1988. Improved technologies in use today can limit harmful emissions from wood burning devices. The EPA needs to update the standards to reflect this new technology. All wood-burning devices can burn cleaner to reduce impacts on public health.

Improve the air pollution monitoring network.

pollution monitoring network. That network forms the public health infrastructure for air pollution. States and local governments use monitors to accurately measure the amount of air pollution in the community.  

  • Less than one-third of all counties have ozone or particle pollution monitors, seriously limiting the ability to adequately detect and track the levels of harmful air pollution.
  • Coverage is especially limited near major highways, where people likely breathe higher levels of air pollution. The EPA needs to expand the monitoring network to include comprehensive coverage in areas near major roads and highways. These monitors are needed to measure the highest levels of exposures air pollution related to traffic. 
  • Unfortunately, funds for existing air pollution monitors have been cut across the nation. These resources may be cut further unless Congress and the White House resolve to protect the health of the nation from air pollution.

Adopt an ozone standard that follows the law and protects health.

  • National air quality standards are the official limits that drive the cleanup of air pollution around the nation. The Clean Air Act requires that the EPA set national air quality standards based on the need to protect public health "with an adequate margin of safety." In 2001, the Supreme Court unanimously ruled that protecting health was the only basis for the standards. The Clean Air Act also requires that the EPA review the standards every five years to make sure that the standards are based on the most current science. 
  • In its previous review, the EPA estimated that setting the standard for ozone to 60 ppb would save 4,000 to 12,000 lives and prevent 21,000 hospitalizations, 58,000 asthma attacks, 5,300 heart attacks, and result in 2.5 million fewer school and work days lost each year. The lower ozone levels would yield $35 billion to $100 billion in health and economic benefits by 2020.5
  • The Obama Administration decided in 2011 to ignore the overwhelming scientific research and the opinion of experts that much stronger standards were needed. Now, the EPA has the opportunity to propose a new, more protective standard. A stronger standard is needed to protect public health.

Protect the Clean Air Act.
The continued improvement shown in the State of the Air report is possible because of the Clean Air Act, the nation's strong public health law that the U.S. Congress passed over 40 years ago. The Act requires that the EPA and each state take steps to clean up the air.  Some members of Congress are proposing changes to the Clean Air Act that could dismantle progress made in the last 40 years. We must keep that law strong to continue to protect public health.

What you can do

Individual citizens can do a great deal to help reduce air pollution outdoors as well. Simple but effective ways include –

  • Tell the President and EPA to set standards for carbon pollution from new and existing power plants. The EPA also needs to set tighter standards for ozone.
  • Send a message to Congress. Urge them to support cleaner, healthier air and oppose measures to block or delay the cleanup of air pollution. They should support and protect the Clean Air Act.
  • Share your story. Do you or any member of your family have a personal reason to want healthier, cleaner air? how healthy air affects you.
  • Drive less. Combine trips, walk, bike, carpool or vanpool, and use buses, subways or other alternatives to driving. Vehicle emissions are a major source of air pollution. Support community plans that provide ways to get around that don't require a car, such as more sidewalks, bike trails and transit systems.
  • Use less electricity. Turn out the lights and use energy-efficient appliances. Generating electricity is one of the biggest sources of pollution, particularly in the eastern United States.
  • Don't burn wood or trash. Burning firewood and trash are among the largest sources of particles in many parts of the country. If you must use a fireplace or stove for heat, convert your woodstoves to natural gas, which has far fewer polluting emissions. Compost and recycle as much as possible and dispose of other waste properly; don’t burn it. Support efforts in your community to ban outdoor burning of construction and yard wastes. Avoid the use of outdoor hydronic heaters, also called outdoor wood boilers, which are frequently much more polluting than woodstoves.
  • Make sure your local school system requires clean school buses, which includes replacing or retrofitting old school buses with filters and other equipment to reduce emissions. Make sure your local schools don’t idle their buses, a step that can immediately reduce emissions.
  • Get involved. Participate in your community's review of its air pollution plans and support state and local efforts to clean up air pollution. To find your local air pollution control agency, go to www.4cleanair.org.
