Airports around the world are making commitments to reduce carbon emissions and lessen the industry's impact on climate change.
96 airports across four continents have been certified under the Airport Carbon Accreditation program.
This independent and voluntary initiative is administered by WSP Environment & Energy, an international consultancy created by ACI Europe.
In order to become accredited under the program, airports need to get their carbon footprints verified by an independent assessor in accordance with the ISO14064 (Greenhouse Gas Accounting) standard.
The latest airports to join the program include Venice Airport, Treviso Airport, Naples Airport and Groningen Airport Eelde.
This brings the total number of European airports certified under the program to 80.
Several existing members have already made significant strides in moving up through the different certification levels.
The airport is the fourth busiest across Europe and is the largest to date to have successfully complete the certification.
Eindhoven Airport has also reached carbon neutral status, while Athens International Airport, Hamburg Airport and Farnborough Airport have moved up to the third level of certification.
