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 2018, SEA confirmed its European leadership positioning for both Linate and Malpensa airports within the "3+ neutrality" grouping, together with 40 other airports, of which 4 are Italian (Naples, Rome, Treviso and Venice), representing 24.2% 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.
SEA’s interventions at both airports resulted in progressive energy savings of 13,589 MWh in 2010 (-7.7% compared to 2009), of 8,353 MWh in 2011 (-5.1% compared to 2010) and of 1,080 MWh in 2012 (-0.7% compared to 2011).
Despite the enlargement of Malpensa Terminal 1 with new infrastructural spaces of 49,600 m2 in 2013, 18,500 m2 in 2014 and 4,950 m2 in 2015, for the operation of the third satellite and north building and the implementation of the new railway station at Terminal 2, SEA nevertheless managed to achieve significant energy savings compared to 2009.
In 2018, consumption in both airports decreased by 4.1% compared to 2017, continuing the positive containment trend compared to 2009, the year in which SEA began energy saving policy interventions.
The main energy saving measures carried out in 2018 were:
- night-time switch off of unused runways under noise reduction programming;
- introduction of low consumption lighting;
- optimization of the air conditioning units (reduction of the ‘minimum external air flow rate’ as a function of the presence of passengers, integration of inverters at thermal substations, optimization of AHUs and mixing chambers, optimization of microclimate);
- continuation of the computerization of energy consumption data and the integration of additional field sensors in order to subdivide and analyse consumption more precisely;
- almost complete elimination of decentralized production centres (boilers, refrigeration units, direct methane use) with consequent further improvements in terms of environmental impact;
- introduction of small electric cars for operators, in addition to the elimination of diesel vehicles in the aeronautical area; revamping of refrigeration units with the integration of new, more efficient units serving both the arrivals and departures buildings of Terminal 2;
- replacement of CDZ heat recovery units in Terminal 1.
We have at both airports co-generation/ tri-generation stations in operation which generate on an ongoing basis energy savings benefitting our Group, the quality of the environment and the inhabitants of neighbouring areas. We offer high efficiency services which allow the generation of savings both for the Company and for clients which, thanks to the use of district heating, achieve savings from heat recovery. No renewable source energy production facilities are in use within the group.
