Although commercial airlines have been replacing their fleets with jets that are quieter and more
fuel efficient, the engines actually emit more of certain pollutants. The Great Lakes Radio
Consortium’s Lester Graham explains:


The federal government’s watchdog agency, the General Accounting Office, issued a report that
finds many airports have worked to reduce air pollution. Some have converted airport ground
vehicles to cleaner burning fuels. Newer jet engines emit less carbon monoxide and
hydrocarbons. But, they produce higher amounts of nitrogen oxides than engines on the older
models. As much as 40-percent more during landings and take offs. Those emissions contribute
to ozone pollution. That’s helping to keep more than half of the nation’s major airports in
violation of the federal ozone standards.


The General Accounting Office noted there are technologies available to limit nitrogen oxides
emissions from some of the newer aircraft models. Many government officials indicate that will
likely have to be the next step if ozone pollution around the airports is to be reduced.
