Four years on from its launch, ACI Europe presented an update on the programme at the ACI Europe and ACI World Annual Congress and Exhibition in Istanbul.
The scheme assesses and recognises airports’ efforts to manage and reduce their CO2 emissions.
It certifies airports at four different levels of accreditation.
In the past twelve months, Airport Carbon Accredited status has been earned by a total of 75 airports in 22 countries in Europe and 10 airports in seven countries in Asia-Pacific.
Earlier in the conference, a special agreement was signed with ACI Africa, extending the programme to African airports.
Enfidha-Hammamet International Airport in Tunisia became the very first African airport to become certified.
All the airports now certified by Airport Carbon Accreditation collectively represent 22% of global air passenger traffic.
Olivier Jankovec, director general of ACI Europe, said: “Year four of Airport Carbon Accreditation has been an epic year.
“We’d seen more airports reducing their CO2 than ever before, including an entire national airport group becoming carbon neutral.
“And now, year five kicks off with the extension to Africa. That’s real momentum for such a young programme.
“In Europe alone, accredited airports welcome more than 900 million passengers each year and year four has yielded a reduction of over 170,000 tonnes of C02 – enough energy to run 71,000 households for a year.”
