Dallas/Fort Worth Airport and air quality improvement
Located halfway between the cities of Dallas and Fort Worth in Texas, Dallas/Fort Worth International Airport handles nearly 1,900 flights each day and 60 million passengers annually.
Did you know?
- Many airports are actively limiting their NOx, CO and other emissions in order to address local air quality issues and at the same time cut greenhouse gas emissions.
- One major way to so this is to focus on converting fleets of ground vehicles, and ground power.
What are we doing?
As of 2005, the following had been achieved by Dallas/Fort Worth Airport:
- 100% of the light and medium duty fleet and 72% of the heavy duty and off-road fleet had been converted to alternative fuel vehicles (AFV), mainly compressed natural gas (CNG).
- 87% of the light and medium fleet meet or exceed super ultra low emission vehicle standards (SULEV)
- 3% of the light and medium fleet were hybrid and electric vehicles
- All of the bus and shuttle van fleet had been converted to AFV
- A total of almost 400 AFV are envisaged by the year 2010
- In the central utility plant, boilers and chillers were replaced with low emission technology resulting in a 97% NOx reduction.
- 18 rapid rechargers for electric vehicles have been installed to supply both the airport vehicles and those purchased by airlines.
What is the result?
- In 1996, the airport sources produced just less than 120 tonnes of emissions dominated by NOx and CO.
- By 2005, with the above measures in place, the annual emissions figure was less than 15 tonnes. Continuation of the vehicle fleet replacement programme will improve this figure.
- This, along with our efforts in other areas, is helping to limit our contribution to climate change.
