Denver International Airport expects to prevent more than 92 tons of carbon monoxide emissions from entering the air thanks to a $442,500 grant by the Federal Aviation Administration.
The FAA implemented the program in 2005 to help airport sponsors meet their air quality responsibilities under the Clean Air Act. Through VALE, airport sponsors can use Airport Improvement Program (AIP) funds and passenger facility charges to acquire low-emission vehicles, refueling and recharging stations, gate electrification, and other airport-related air quality improvements.
At DIA, the grant will be used to purchase pre-conditioned air (PCA) handlers that allow aircraft to shut off their auxiliary power units while parked at the gate and connect to a cleaner central heating and cooling system, saving the airline fuel and reducing emissions. This project also will improve air quality in the ramp and gate areas.
In addition to shrinking its carbon footprint over the expected 13-year life of the systems, DIA expects the new equipment to prevent more than 134 tons of pollutants that cause ozone pollution.
Other US airports are implementing similar sustainability measures such as Miami International, which has expands its recycling program to include glass, plastic and metal containers, along with paper and cardboard materials. And last year the Chicago Department of Aviation (CDA) hired a herd of goats to provide sustainable vegetation management at O’Hare International Airport.
