Climate & energy


Climate protection is a top priority for Flughafen Zürich AG. It has set itself concrete goals to significantly reduce its own CO2 emissions.

Impact of aviation on the climate

Based on today's scientific knowledge, aviation influences the climate mainly through emissions of carbon dioxide (CO2). Other significant emission products which can cause changes in the atmosphere are nitrogen oxides, water vapour and particulate matter. Aviation accounts for 1.5% of all global man-made CO2 emissions (according to the IPCC-Report). When combined with other effects created by aircraft, such as cloud formation and soot particles, it contributes 3.5% towards global warming (with a 1-10% range of uncertainty).


Successful reduction at the airport

Flughafen Zürich AG as the airport operator is part of the aviation system and acknowledges the increasing importance of long-term climate protection, even though it is only responsible for approximately 10% of the CO2 emissions of the airport system. We are committed to ensuring that aviation evolves in an environmentally-friendly manner.

All CO2 emissions have been calculated in detail since 1991 according to the GHG protocol (Greenhouse Gas). Flughafen Zürich AG has been able to reduce the applicable emissions (scopes 1 and 2) through various measures by approximately 50% since 1991. In 2018, Flughafen Zürich AG's CO2 emissions amounted to approximately 26,800 tonnes in scopes 1 and 2. Further information can be found in the Annual Report.


Ambitious goals

We decided to voluntarily reduce our CO2 emissions to 20,000 tonnes by 2030 and to 10,000 tonnes by 2040. We further ultimately aim towards Zero-Emissions in 2050.
The climate protection programme has been accredited at level 3 of the independent Airport Carbon Accreditation of the Airport Council International EUROPE. This means that not only has our airport mapped and reduced the CO2 emissions under its direct control, but also that we have engaged other stakeholders on the airport site to reduce their CO2 emissions as well.


Flughafen Zürich AG's key objectives include using energy efficiently and keeping consumption as low as possible.

Photovoltaics is constantly being expanded.

2030 energy strategy

Flughafen Zürich AG has taken a careful look at its energy future. With the energy strategy it approved in 2013, it is aiming for a secure, economical and environmentally sound energy supply by 2030. Key successes have already been achieved. The consumption of energy for heating purposes has been significantly reduced since 1994. More renovation and replacement projects are planned over the next few years, and these should serve to further reduce energy consumption. 

Alternative energies

Alternative energies are an important pillar for achieving the goals of the energy strategy 2030. Since 2003, a photovoltaic system has been producing electricity on the roof of Dock E, and underground energy piles provide energy for cooling and heating. Since then, several photovoltaic systems have been added and the use of geothermal energy has also been expanded.

Today, Flughafen Zürich AG operates eleven photovoltaic systems on roofs with a total installed capacity of 2400 KWp. Around 2300 KWh of electricity can thus be produced per year, which corresponds to approximately 1.4% of the airport's total requirements. Further systems for alternative energy generation are in the planning stage.
