Air traffic and the German airports are bearing more and more responsibility for climate and the environment. Therefore, the long-term business development of Cologne Bonn Airport is closely linked to climate protection guidelines.
The Airport has made a commitment to CO2-neutral growth. The objective is that, taking 2005 as the reference year, emissions will on a long-term basis be kept at least constant. Until 2020, the 55,000-tonne mark of carbon dioxide (CO2) may not be exceeded. If the RECS certificates, with which the Airport obtains its eco-hydro electricity, were also taken into consideration, the CO2 emission would be decreased by almost 30 percent by 2020.
In the past, the annual CO2 emission was also considerably reduced by technical innovations and the efficient use of energy. This included the construction of a combined heating and power unit, energy-efficient heating, ventilation and air conditioning systems, the installation of roof solar systems in the Cargo Center and the new FedEx sorting centre, plus sourcing regenerative or emission-free hydro-electricity (RECS certificates), all of which led to a considerable improvement of the carbon balance. Since 1998, more than 135,000 tonnes of carbon dioxide have been saved.
To continue with this reduction of absolute carbon dioxide emissions until 2020, further investments are planned for energy efficiency projects. This includes the installation of LED technology in Terminal 1, another photovoltaic system on the roof of the UPS building and a modern heating, ventilation and air conditioning system in Terminal 1. A climate protection management system, which will monitor the effects of the individual reduction measures and identify further CO2-saving potential, will also be set up.
