A host of carbon reducing initiatives over the last decade proved instrumental to the Hungarian gateway's success in achieving the milestone.
Its efforts have included replacing the lighting fixtures in the terminals with energy-saving LED-based systems, and it continues to refurbish and maintain the district heating pipes as well as the pumps of its water supply system.
As a result of its efforts, CO2 emission of Budapest Airport per passenger was reduced by as much as 44% over the last five years.
“In Europe, only thirty airports are in the elite club of carbon-neutral operations, and in Central-Eastern Europe we are the first to receive this accreditation,” enthuses Gábor Szarvas, Budapest Airport's environmental director.
“Since passenger traffic has been increasing significantly, we are continuously working on making the airport operation greener, in the framework of our Greenairport programme.
"This summer the new passenger pier at Terminal 2B will be handed over, featuring state-of-the-art heating and cooling technologies.
"In addition, we continue to increase the number of electric vehicles at the airport and to commission charging stations, reducing CO2 emissions due to fossil fuels.”
Apart from "optimising" its own operation, Budapest Airport is also encouraging its partners at the airport as well as all other organisations and authorities to adopt sustainable practices.
The Greenairport initiative was launched three years ago, aimed at making the operation of the gateway sustainable via joint environmental actions.
The energy consumption of the airport – based on the energy consumed for making hot water, heating, and lighting – is equivalent with the energy consumption of 23 thousand households, the energy demand of a small town.
