With regard to carbon dioxide emissions, SEA is committed to maintaining the neutrality level achieved through

  • constant and effective process rationalisation
  • use of renewable energy sources
  • purchase of carbon offsets

In 2019, SEA confirmed its European leadership positioning for both Linate and Malpensa airports within the 3+ neutrality grouping, together with 51 other airports, of which 4 are Italian (Naples, Rome, Treviso and Venice), representing 26.2% of European traffic.

The trend of recent years shows a constant and incisive commitment and SEA is committed to maintaining this level of neutrality through the constant effective rationalization of processes, energy saving policies, sustainable mobility and through the purchase of offset.

CO2 emissions




In June 2020, SEA committed to the “NetZero2050” resolution promoted by ACI Europe, which requires its 500 members to reach “net zero” CO2 emissions by 2050.

This commitment is accompanied by a need for the aviation sector to develop a shared long-term goal and vision towards achieving zero carbon emissions.

Operators at zero emissions airports will not be able to purchase “off-set credits” to achieve neutrality.

Offsetting is considered a temporary measure to deal with residual emissions, which airports will gradually have to replace with the use of renewable energy as new technologies and decarbonisation opportunities arise.

NetZero2050 has been signed by over 200 airports managed by more than 47 airport operators in 42 European countries.

Based on current European airport traffic volumes (2.34 billion passengers welcomed in 2018) and the estimated carbon footprint, this commitment to zero emissions will hopefully reduce annual emissions by 3.46 million tons by 2050.

As such, SEA and the European airport industry are aligning themselves with the Paris Agreement and the latest reports from the IPCC, which reaffirm the need to guarantee a temperature rise of no more than 1.5°C.
