Dubai Airports’ conservation efforts reduced its gateways CO2 emissions by 72,793 tonnes, saved 131.9 million gallons of water and achieved $4.3 million in fuel savings last year.
“We take our environmental responsibility very seriously and as we step up efforts to limit our footprint, it’s becoming increasingly clear that green business is good business,” says Dubai Airports CEO, Paul Griffiths.
Dubai Airports attributes its success to its "aggressive campaign" to conserve water and reduce power consumption across both of its airport properties.
By installing energy-saving lamps and occupancy sensors, re-setting air conditioning by three degrees (from 21 degrees Celsius to 24 degrees), and implementing chiller management systems, it managed to save over 21.4 million kilowatt/hours of electricity worth $2.21 million – equivalent to 9,993 tonnes of CO2 during 2011.
At Dubai World Central, the conservation of 2.242 million kWh of electricity saved $272,000 and equivalent 1,906 tonnes of CO2 during the same time frame.
Water conservation efforts led to a reduction of 126.45 million gallons and savings of $1.3 million at Dubai International last year.
At DWC water savers were introduced in all facilities, resulting in the conservation of 696,000 gallons of water worth $7,500.
Additionally the use of treated sewage effluent water for irrigation has resulted in the saving of 4.75 million gallons of potable water worth $52,000.
During the year under review, the company also set a new standard in the region with the installation of the largest solar panel array for any airport in the Middle East.
Thanks to the considerable contributions and support of long standing partner Air BP, the array consists of 92 panels of high efficiency photo-voltaic cells providing 21.6 KW capacity.
Located atop the airport's Car Park B, it provides enough power to offset fully the energy consumed by the lighting and plasma displays in the airport’s historical photo exhibition.
The installation has a lifespan of 25 years, and will continue to provide free, clean energy to Dubai International during its lifetime.
Dubai Airports will join other energy-conscious organisations across the world on March 31 to mark Earth Hour by switching off all non-essential lights across Dubai International Airport's three terminals and at Dubai World Central.
Last year Dubai International’s demand for electricity dropped by 11 Megawatts from 80 MW to 69 MW during the one hour event.
“Our ultimate goal is to contribute to the development of a clean, sustainable future in which airports, aircraft and all ancillary services are carbon-neutral,” adds Griffiths.
