The carbon management certification standard for airports competed against 269 entries in the World You Like contest.
EU Commissioner for Climate Action, Connie Hedegaard, announced the finalists and winner in the Sustainia Awards ceremony in Copenhagen last night.
The voluntary climate change initiative was recognised as an efficient and innovative climate solution that is making a real difference in helping airports address their CO2 emissions.
Olivier Jankovec, director general ACI Europe, says: "We are delighted that Airport Carbon Accreditation has won this distinction at Sustainia tonight.
"We launched this programme four years ago during the worst trading conditions, but our faith was quickly rewarded by solid uptake from airports all around Europe and beyond.
“This is a fantastic recognition for the 90 airports that are currently certified under the programme - for their on-going work to map, reduce, optimise and ultimately neutralise their carbon emissions.”
In Europe, 77 airports in 24 countries are currently certified at one of the 4 available levels of certification, among the 90 around the globe, which include 12 airports in the Asia-Pacific region of ACI and 1 airport in ACI Africa's region.
In year 4 of the programme (June 2012 to May 2013), the collective reduction achieved was over 170,000 tonnes of CO2, enough energy to power 71,000 households for a year.
